Answer:
They are not congruent
Step-by-step explanation:
the 4cm in the first triangle is located opposite of the 37 degrees. in the second traingle, the 4cm length is adjacent to the 37 degrees. thus, they are not congruent.
Your answer would be A: y = 1/4x +9
Answer:
A belt costs $15 and a wallet costs $27.
Step-by-step explanation:
Let's mark price of a belt with x and price of the wallet with y. That leaves is with a system of equations:
x + y = $42
7x + 4y = $213
The goal when solving this system is to get rid of one of the variables. We can do that by multiplying first equation with -4:
-4x - 4y = -168
7x + 4y = 213
Now, we simply add these two equations up:
-4x - 4y + 7x + 4y = -168 + 213
3x = 45
x = $15
Now, we plug in x into any of the two starting equations to find y:
x+y=42
15 + y = 42
y = $27
Answer:
x = 7.5
Step-by-step explanation:
Given
- 15 = ( multiply both sides by - 0.5 to clear the fraction )
- 15 × - 0.5 = x
7.5 = x
