Do you know what D equals?
Answer:
The answer is 3
Step-by-step explanation:
7 - 4 = 3
So, 3+4=7
To get to 20 minutes from 2 minutes you multiply by 10, do the same to the 30 problems to get 300. The answer is 300 problems in 20 minutes.
Answer:
m∠I = 50 degrees
Step-by-step explanation:
Mathematically, the base angles of an isosceles triangle are equal
So in this case, since H is a vertex;
m∠I + m∠H + m∠G = 180
m∠I = m∠G = x
2x + 80 = 180
2x = 180-80
2x = 100
x = 100/2
x = 50
