Step-by-step explanation:
3/17 = u/13
Cross multiply:
3 * 13 = 17 * u
Simplifying
3 * 13 = 17 * u
Multiply 3 * 13
39 = 17 * u
Solving
39 = 17u
Move all terms containing u to the left, all other terms to the right.
Add '-17u' to each side of the equation.
39 + -17u = 17u + -17u
Combine like terms: 17u + -17u = 0
39 + -17u = 0
Add '-39' to each side of the equation.
39 + -39 + -17u = 0 + -39
Combine like terms: 39 + -39 = 0
0 + -17u = 0 + -39
-17u = 0 + -39
Combine like terms: 0 + -39 = -39
-17u = -39
Divide each side by '-17'.
u = 2
Simplifying
u = 2.294117647
Answer:
A) 22x-11
B) 121 cupcakes
Step-by-step explanation:
The expression that shows how many peanut butter
cupcakes she baked is 5 (2x-4) + 3(3+4x).
To simplify this, we need to use the distributive property:
We expand using the distributive property to get:
We group similar terms on the right to obtain:
Combine similar terms on the right to get:
Therefore the simplified expression is
B) We want to find how many cupcakes Mrs Jones baked last week, when x=6.
We substitute 6 into the simplified expression for x to get
Therefore she baked 121 cupcakes last week.
