Let's set up an equation to solve this problem. Let's say the number of cupcakes JoJo decorates is 'x'. According to the information given, Darcy decorates 8 cupcakes, which is 2 more than 13 times the number of cupcakes JoJo decorates.
So, we can write the equation as:
8 = 13x + 2
To solve for 'x', we subtract 2 from both sides of the equation:
8 - 2 = 13x
Simplifying, we get:
6 = 13x
Finally, we divide both sides of the equation by 13 to solve for 'x':
6/13 = x
Therefore, JoJo decorates approximately 0.46 cupcakes. However, since we are working with whole numbers, we should round this value to the nearest whole number.
Hence, JoJo decorates approximately 0 cupcakes. (rounded down to the nearest whole number).
To find out how many cupcakes JoJo decorates, we need to use the information provided.
It is given that Darcy decorates 8 cupcakes, which is 2 more than 13 cupcakes that JoJo decorates.
Let's set up an equation to solve for the number of cupcakes JoJo decorates:
Cupcakes decorated by Darcy = Cupcakes decorated by JoJo + 2
Given that Cupcakes decorated by Darcy = 8 and Cupcakes decorated by JoJo = x (unknown), we can write:
8 = x + 2
To solve for x, the number of cupcakes JoJo decorates, we need to isolate x on one side of the equation.
By subtracting 2 from both sides of the equation, we have:
8 - 2 = x
6 = x
Therefore, JoJo decorates 6 cupcakes.
divide - 3/17 by -2/3
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by swapping the numerator and the denominator.
So, to divide -3/17 by -2/3, we can rewrite it as:
-3/17 ÷ -2/3
Reciprocal of -2/3 is -3/2.
Now we have:
-3/17 x -3/2
Multiplying the numerators and denominators, we get:
(-3) x (-3) / (17) x (2)
Simplifying, we have:
9 / 34
Therefore, -3/17 ÷ -2/3 equals 9/34.
find the product
4/7(- 20/2)
To find the product of two fractions, we simply multiply the numerators together and then multiply the denominators together.
In this case, the product of 4/7 and -20/2 can be calculated as follows:
(4/7) x (-20/2)
Multiplying the numerators (4 x -20) and the denominators (7 x 2), we get:
-80/14
This fraction can be simplified by finding the greatest common divisor. In this case, the greatest common divisor of 80 and 14 is 2.
Dividing the numerator and denominator by 2, we get:
(-80/14) ÷ 2 = -40/7
Therefore, the product of 4/7 and -20/2 is -40/7.
