Answer:
The sum is
Step-by-step explanation:
Assuming we are finding the sum of :
3e + 7 - e and 2e + 10 + 2e -3
Then we set up the addition as follows:
We group similar try to get:
We now combine the similar terms to obtain:
Therefore the sum is
Answer:
17°
Step-by-step explanation:
ΔXWZ = ΔYWZ (they are congruent triangles so ∠XWZ = ∠YWZ)
5x - 8 = 9x - 28
Rearrange and collect the like terms
-8 + 28 = 9x - 5x
20 = 4x
x = 5°
∠YWZ = 9x - 28
sub x = 5
= 45 - 28
= 17°
Answer:
The value of x is 21 .
Step-by-step explanation:
We are given that x varies directly as y
--- A
We are given that x = 7 and y = 28
Substitute the values in A
7 = 28k
Now equations becomes :
y = 84
Hence The value of x is 21 .

Answer:
5. there was a: 18% decrease.
6. if the intial value was 285 and there was a 15 difference then the final value is 300. The change is 5.26%.
