Answer:
x=12
Step-by-step explanation:
If the triangles are similar:
x/8=18/12
x/8=1.5
x=12
Answer:
X = 3 x − 14
y = − x + 5
Step-by-step explanation:
Solve for the first variable, then substitute the result into the other equation.
Answer:
1/4 of them were rotten
rotten ones = 1/4 × 12 = 3
ones that weren't rotten = 12 - 3 = 9
