Z = 75

You can simply do the reverse operation of this, which would be division, and find the answer that way. 15/0.2 is 75 and that's your answer! You can check by doing "75 x 0.2", which would give you 15, your starting answer. Hope this helped!

HELP!!! (x+3)²+8=72 (quadratic equation)

svet-max [94.6K]

Answer:

x = 5 or x = -11

Step-by-step explanation:

(x+3)²+8=72

x² + 6x + 9 + 8 = 72

x² + 6x -55 = 0

(x - 5) (x + 11) = 0

x = 5 or x = -11

Points B, D, and F are midpoints of the sides of ACE. EC = 32 and BF = 2x - 10. Find the value of x.

Svetlanka [38]

Answer:

Step-by-step explanation:

Remark

This only works if B is between AC and F is between AE

Givens

CE = 32

BF = 1/2 CE Properties of midpoints. BF is parallel to and 1/2 of CE

BF = 1/2 * 32

BF = 16

Equation

2x - 10 = 16 Add 10 to both sides

2x - 10 + 10 = 16 + 10 Combine

2x = 26 Divide by 2

2x/2 = 26/2 Do the division

x = 13

The equation d=m/v. is m-d=v an equivalent equation?

RUDIKE [14]

Answer:

They are not equivalent equations

Step-by-step explanation:

d=m/v

Multiply each side by v

d * v = m/v *v

dv = m

Divide each side by d

dv/d = m/d

v = m/d

This is not the same as v = m-d

They are not equivalent equations

Answer:

The answer is 1.5

Step-by-step explanation:

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 7x - 7 = 5x - 4 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 7x - 5x = - 4 + 7 \\ \: 2x = 3\\x = \frac{3}{2} \\ x = 1.5$

i hope so..
