THESE ARE THE RIGHT ANSWERS FOR TEXAS CONNECTIONS UNIT 3 LESSON 9
Im a freshman im also in ALG 1A so it might be diff for others but here are the answers believe me of you dont have to but those the answer soo yeah:p
If you’re going to put up the wrong answers don’t put them up
hey guys! please understand that the teachers swapped questions so they won't all be the same 4 everyone :-)
1. is the equation true, false, or open? 9p + 8 = 10p + 7
Open; there is a variable
2. which value is a solution of the equation 5-4x=-3?
2 or letter (b)
Subtract 5 from both sides:
5 - 4x - 5 = -3 - 5
- 4x = -8
Divide -4 from both sides
-4x/-4 = -8/-4
x = 2
3. which ordered pair is a solution of the equation y=x-3?
(5,2)
4. which ordered pair is a solution of the equation y=5x?
(-2,-10)
5. which ordered pair is a solution of the equation y=-5x+4?
(d) or (5,-21)
6. tony and his sister maria have the same birthday but tony is five years older than maria. let the variable x represent tony's age and y represent maria's age. which graph represents the relationship between tony's age and maria's age?
1st graph or the graph where the arrow is going up from 5 (maria's age)
7-11. solve the following equations:
(1) ,, -4=g+1
g=−5
(2) ,, z-4=-8
z=−4
(3) ,, 6.4=4x
x=8/5 =1 3/5 = 1.6
x = 1.6
(4) ,, -3 = x/5
x=−15
(5) ,, -4=7/33x
x=-132/7
!! IF YOU'RE UNSURE WHETHER THESE ARE CORRECT OR NOT, i suggest you use the microsoft math solver !!
12. which equation is an identity? (remember!! "If solving a linear equation leads to a true statement such as 0 = 0, the equation is an identity.")
5w + 8 - w = 6w - 2(w - 4)
13. which equation has no solution?
5v + 3 = 5v – 5
14-15. solve the following equations:
(1) ,, 5(z-4)-z=4z-20
infinitely many solutions
(2) ,, 5+7x=11+7x
no solutions
16. Ella and Margaret were at a carnival. They each got a ticket to the Ferris wheel. Ella got a snow cone, and Margaret got a cotton candy. Ella had a certificate for $6 off the cost. Margaret paid the rest, which came to $12.75. Each Ferris wheel ticket is $5. And a snow cone is $3.50. What was the cost of the cotton candy?
(b) or $5.25
17-19. solve the following equations:
(1) ,, 6(z-2)+4=10
z = 3
(2) ,, 96=-6(-4-3y)
y = 4
(3) ,, -6p+7=3(2p-3)-4(-10+4p)
p = 6
as always, check your work!! if you don't understand a problem ask for help (´▽`ʃ♡ƪ)
