You would evaluate by plugging in the given number of 7 to get your answer.
Janine = J = 15
Leah = L = ?
L = J + 6
L = 15 + 6
L = 21
So Leah spent $21
Answer:

Step-by-step explanation:
By applying geometric mean theorem in the given right angle,

By substituting values in the given ratio,




Exact value of y is
.
Answer:
Consecutive integers:
x
(x+1)
(x+2)
Now your equation is given by sum of the first and twice the third is equal to four times the second decreased by five:
x+2(x+2) = 4(x+1)-5
Step-by-step explanation:
X=0.2
All you have to do is simplify both sides of the equation. Add 3x to both sides. Then subtract 0.8 from both sides.
