Answer:
Height is 7m
Step-by-step explanation:
B = 10 feet area = 35 feet 2 Find the height of the triangle.
Area of triangle = 1/2 b×h
35 = 1/2(10×h)
35 × 2 = 10h
70 = 10h
h = 70/10
h = 7m
Answer:
the answer is -31/20
Step-by-step explanation:
The answer is 5x + 76y
There is no complete standard form because there is no value for x or y given.
Answer:
Shira: x = 8
Samuel: m = 0
Step-by-step explanation:
Shira's mistake was that she subtracted 2 from both sides instead of adding to on both sides.
Correct Solving:
2x - 2 = 14
Add 2 to both sides;
2x = 16
Divide both sides by 2;
x = 8
Samuel's mistake was that when he distributed -2 to 8m and 8 he put the wrong sign for -2 * 8.
Correct Solving:
-2(8m + 8) = -16
Distribute;
-16m - 16 = -16
Add 16 to both sides;
-16m = 0
Divide both sides by -16;
m = 0
