The operator that can be inserted to make the statement true is the addition operator (+). The correct expression would be:
6 - 1/4 * 28 - 2 1/4 + 3/4 + 2 * 2 - 11
6 - 1/4 times 28 - 2 1/4 ________ 3/4 + 2 times 2 - 11
Which operator cab be inserted to make the statement true?
6 - 1/4 * 28 - 2 1/4 + 3/4 + 2 * 2 - 11
6 - 1/4 times 28 - 2 1/4 ________ 3/4 + 2 times 2 - 11
Which operator cab be inserted to make the statement true?
A. >_
B. =
C. <
D. >
6 - 1/4 * 28 - 2 1/4 ________ 3/4 + 2 * 2 - 11
= 6 - 7 - 2 1/4 ________ 3/4 + 4 - 11
= -1 - 2 1/4 ________ 3/4 - 7
= -1 - (2 + 1/4) ________ (3 - 7/4)
= -1 - (9/4) ________ (12/4 - 7/4)
= -1 - (9/4) ________ 5/4
Now let's compare the two sides of the expression:
-1 - (9/4) _____ 5/4
To evaluate this comparison, we can convert both sides to have a common denominator:
-1 - (9/4) _____ 5/4
-4/4 - (9/4) _____ 5/4
(-4 - 9)/4 _____ 5/4
-13/4 _____ 5/4
Since -13/4 is less than 5/4, we can conclude that the correct operator to make the statement true is C. < (less than).
The inequality is: -32.5 - 6b ≥ 48.5
Let's start by isolating the variable b.
Add 32.5 to both sides of the inequality:
-32.5 - 32.5 - 6b ≥ 48.5 + 32.5
-6b ≥ 81
Divide both sides of the inequality by -6, remembering to reverse the inequality sign when dividing by a negative number:
b ≤ 81 / -6
Simplifying:
b ≤ -13.5
Therefore, any value of b that is less than or equal to -13.5 will make the inequality -32.5 - 6b ≥ 48.5 true.
A. 4x + 8 = -4
B. 4x + 8 = 4
C. 4x - 8 = 4
D. 4x - 8 = -4
A. 4(-3) + 8 = -4
-12 + 8 = -4
-4 = -4 - This equation is false.
B. 4(-3) + 8 = 4
-12 + 8 = 4
-4 = 4 - This equation is false.
C. 4(-3) - 8 = 4
-12 - 8 = 4
-20 = 4 - This equation is false.
D. 4(-3) - 8 = -4
-12 - 8 = -4
-20 = -4 - This equation is true.
Therefore, the equation that has the solution set {-3} is D. 4x - 8 = -4.
A. { x : 5/2 <_ x < 7}
B. { x : 5/2 <_ x < 1}
C. { x : 3 <_ x <7}
D. { x : -3/2 <_ x <1}
First, let's solve the left inequality: -2 ≤ 2x + 1/3 - 4
Adding 4 to both sides:
2 ≤ 2x + 1/3
Subtracting 1/3 from both sides:
2 - 1/3 ≤ 2x
Multiplying both sides by 1/2:
1 2/3 ≤ x
So the solution to the left inequality is x ≥ 1 2/3 or x ≥ 5/3.
Now let's solve the right inequality: 2x + 1/3 - 4 < 1
Adding 4 to both sides:
2x + 1/3 - 4 + 4 < 1 + 4
2x + 1/3 < 5
Subtracting 1/3 from both sides:
2x < 5 - 1/3
Simplifying:
2x < 14/3
Dividing both sides by 2:
x < 7/3
So the solution to the right inequality is x < 7/3.
As we are looking for the intersection of both solution sets, the solution to the compound inequality is: x ≥ 5/3 and x < 7/3.
Simplifying this interval notation, we get:
{ x: 5/3 ≤ x < 7/3}
which is the same as:
{ x: 1 2/3 ≤ x < 2 1/3}
Therefore, the correct answer is A. { x: 5/2 ≤ x < 7}
9d/4 + 3 - 2d = -2(3 + d)
First, distribute -2 to both terms inside the parentheses:
9d/4 + 3 - 2d = -6 - 2d
Next, let's combine like terms on both sides of the equation:
9d/4 - 2d + 2d = -6 - 3
Simplifying further:
9d/4 = -9
To eliminate the fraction, we can multiply both sides of the equation by 4:
4 * (9d/4) = 4 * (-9)
9d = -36
Finally, divide both sides of the equation by 9 to solve for d:
d = -36/9
d = -4
Thus, the linear equation that has the same solution set as 9d/4 + 3 - 2d = -2(3 + d) is d = -4.
A. 35 - 15b = 95
B. 4w - 2 ( 7 - 3w) = w/3 - 6
C. 14 = 7/4 x - 19/4 + 2x
D. 3x/5 - 10 = -7
9d/4 + 3 - 2d = -2(3 + d)
First, distribute -2 to the terms inside the parentheses:
9d/4 + 3 - 2d = -6 - 2d
Next, let's combine like terms on both sides of the equation:
9d/4 - 2d + 2d = -6 - 3
Simplifying further:
9d/4 = -9
To eliminate the fraction, we can multiply both sides of the equation by 4:
4 * (9d/4) = 4 * (-9)
9d = -36
Finally, divide both sides of the equation by 9 to solve for d:
d = -36/9
d = -4
Now let's compare the simplified equation d = -4 with the options provided:
A. 35 - 15b = 95
B. 4w - 2 ( 7 - 3w) = w/3 - 6
C. 14 = 7/4 x - 19/4 + 2x
D. 3x/5 - 10 = -7
None of the options provided match the solution d = -4.
Therefore, none of the options A, B, C, or D have the same solution set as the given equation 9d/4 + 3 - 2d = -2(3 + d).
A. g > -5
B. g < -5
C. g < 71/-17
D. g > 71/-17
Let's start by getting all the g terms on one side of the inequality:
-12g + 18 > -5g + 53
Add 12g and subtract 53 from both sides:
-12g + 12g + 18 - 53 > -5g + 12g + 53 - 53
18 - 53 > -5g + 12g
Combine like terms:
-35 > 7g
Divide both sides by 7, remembering to flip the direction of the inequality when dividing by a negative number:
-35/7 < g
Simplify:
-5 < g
So, the solution to the inequality -12g + 18 > -5g + 53 is g > -5.
Therefore, the correct option is A. g > -5.
Let's start with the first inequality:
4x - 3 > 9
Add 3 to both sides:
4x - 3 + 3 > 9 + 3
4x > 12
Divide both sides by 4:
x > 12/4
x > 3
So, the solution to the first inequality is x > 3.
Now let's solve the second inequality:
x + 6 > -2
Subtract 6 from both sides:
x + 6 - 6 > -2 - 6
x > -8
So, the solution to the second inequality is x > -8.
To find the intersection of the solution sets, we take the smaller of the two values. In this case, the smaller value is x > 3.
Therefore, the solution set for the given inequalities is { x : x > 3 }.
The equation is defined for all values of x except for those that would make the denominator of the expression 7x/9 equal to zero.
To find the undefined value, we set the denominator equal to zero and solve for x:
9 = 0
However, there is no value of x that satisfies this equation. Therefore, there is no undefined value for the given equation 14 = 7x/9 + 4x. The equation is defined for all real values of x.
A. x not equal 9/4
B. x not equal 0
C. x not equal -9/4
D. x not equal -4/9
The equation is defined for all values of x except for those that would make the denominator equal to zero. In this case, the denominator is the sum of 7x/9 and 4x.
To find when this denominator would be zero, we set it equal to zero and solve for x:
7x/9 + 4x = 0
To simplify, we can find a common denominator:
(7x + 36x)/9 = 0
Combining like terms:
43x/9 = 0
Now, to have a zero denominator, we need 43x to be equal to zero:
43x = 0
Dividing both sides by 43, we find:
x = 0/43
x = 0
Therefore, the undefined value for the equation 14 = 7x/9 + 4x is B. x is not equal to 0.
1. First, let's simplify the equation by combining like terms:
11/s + 7 = 5
2. Next, we subtract 7 from both sides of the equation:
11/s = 5 - 7
11/s = -2
3. To isolate the variable s, we multiply both sides of the equation by s:
s * (11/s) = s * (-2)
4. The s term in the numerator and denominator cancels out on the left side of the equation:
11 = -2s
5. Lastly, we divide both sides by -2 to solve for s:
11 / -2 = -2s / -2
-5.5 = s
Therefore, the solution to the equation 11/s + 3 + 4 = 5 is s = -5.5.
1. Start by multiplying both sides of the equation by 2 to eliminate the fraction:
2A = h ( b1 + b2 )
2. Divide both sides of the equation by ( b1 + b2 ) to isolate h:
2A / ( b1 + b2 ) = h
Therefore, the correctly rearranged formula for the height (h) of a trapezoid is:
h = 2A / ( b1 + b2 )
To isolate d, multiply both sides of the equation by v:
t * v = (d/v) * v
This simplifies to:
t * v = d * (v/v)
Since v/v equals 1, we have:
t * v = d
Now, d is isolated and we have the formula for distance:
d = t * v
A. addition
B. subtraction
C. multiplication
D. division
By multiplying both sides of the equation by v, we have:
t * v = (d/v) * v
This simplifies to:
t * v = d
Therefore, the correct operation to isolate the distance is C. multiplication.
According to the deal, if Sebastian buys three tires at the cost of x dollars each, the fourth tire would cost $5.
So, the total cost of four tires would be 3x + $5.
Given that the total price of all four tires is $237.50, we can set up the equation:
3x + $5 = $237.50
Subtracting $5 from both sides of the equation:
3x = $237.50 - $5
3x = $232.50
To find the cost of each of the first three tires (x), we divide both sides of the equation by 3:
x = $232.50 / 3
x ≈ $77.50
Therefore, the cost of each of the first three tires is approximately $77.50.
