Answer:
8. m=6
9. x=2; Alyssa is incorrect because she subtracted 8 from 16 when in reality she should have divided 16 by 8 to get 2. The real solution is 2 because 8 times 2 is equal to 16.
Step-by-step explanation:
Question 8:
2m-6=m
-2m -2m (subtract 2m from both sides)
<u>-6</u>=<u>-m</u>
- - (divide both sides by the negative)
m=6
Question 9:
<u>8x</u>=<u>16 </u> (divide both sides of the equation by 8)
8 8
x=2
B (2x+5y=-10) is the answer.
Answer:
See below
Step-by-step explanation:
To solve for d, multiply both sides of the equal sign by 4.
4(1/4d) = 4 (1/5g(g+e)-h)
4/4d = 4(1/5
+ 1/5ge - h)
d = 4/5
+ 4/5ge - 4h
A and E are corresponding angles so A=E
