What 3D figure/shape is it?
Answer:
angle BED and angle DEB are the answers.
The answer is D because when multiplied by 1/10 you move the decimal place of 7 one space to the left so 7 now equals .7 and when multiplied by 1/100 23 is moved two spaces to the left to make .23
Subtract the powers
c. 9-7 so 10^2
d. 8-1 so 5^7
x -y = 1
5x + 3y = 45
Solve the first equation for x: x = y + 1
Substitute x in the second with y + 1
5x + 3y = 45
5(y + 1) + 3y = 45
5y + 5 + 3y = 45
8y + 5 = 45
8y = 40
y = 5
Substitute 5 for y in x = y + 1
x = y + 1
x = 5 + 1
x = 6
Answer: (6, 5)
