Answer:
x = -11
Step-by-step explanation:
-2(x+3)+5x = -39
distribute the -2 to what's inside the paranthesis
-2x -6 +5x = -39
combine like terms
3x - 6 = -39
add 6 to each side
3x = -33
divide each side by 3
x = -11
If a cube has a volume of 64 cubic inches, what is the area of the base of the cube?
Answer:
A = 16 cubic inches
Explanation:
If the volume is 64 cubic inches, that means each side (length, width, and height) are 4 inches each. This makes the area (l × w) is 16 cubic inches

if DF=78, DE=5x-9, and EF=2x+10 Find EF
Answer:
EF = 32
Step-by-step explanation:
DE + EF = DF
5x - 9 + 2x + 10 = 78
5x + 2x + 10 - 9= 78
7x + 1 = 78
7x = 78 - 1
7x = 77
x = 77/7
x = 11

If EC bisects BED, find m BED.
A. 128°
B. 130°
C. 134°
D. 136°
Answer:
19x+22
Step-by-step explanation:
Answer:
D. 136°
Step-by-step explanation:
[tex]\because \overrightarrow{EC} \:bisects \: \angle BED. \\
\therefore m\angle BEC = m\angle DEC\\
\therefore (11x+2)\degree = (8x+20)\degree \\
\therefore 11x + 2 = 8x + 20\\
\therefore 11x - 8x = 20-2\\
\therefore 3x = 18\\
\therefore x = \frac{18}{3}\\
\therefore x = 6\\\\
\because m\angle BED= m\angle BEC + m\angle DEC\\
\therefore m\angle BED= (11x+2)\degree + (8x+20)\degree\\
\therefore m\angle BED= (19x+22)\degree \\
\therefore m\angle BED= (19\times 6+22)\degree \\
\therefore m\angle BED= (114+22)\degree \\
\huge \purple {\boxed {\therefore m\angle BED= 136\degree}} \\[/tex]

what is the solution for x in 12x-4=5x+24
Answer:
x = 4Step-by-step explanation:
12x - 4 = 5x + 24
First subtract 5x from both sides
That's
12x - 5x - 4 = 5x - 5x + 24
7x - 4 = 24
Add 4 to both sides
That's
7x - 4 + 4 = 24 + 4
7x = 28
Divide both sides by 7
We have the final answer as
x = 4Hope this helps you
Answer:4
Step-by-step explanation:First, add 4 to both sides of the equation. Then subtract 5x from both sides. Finally, divide both sides by 7.

Answer:
B
Step-by-step explanation:
I answered it on edge
2.45 seconds will it take for the egg to reach the ground.
What is height?Height can be defined the vertical distance from the top to the base of the object.
Given
Height h(t) = 90 ft
Acceleration due to gravity a = -16 ft/[tex]s^{2}[/tex]
Initial velocity v = 0
[tex]h_{0}[/tex] = 0
[tex]h(t) = at^{2} +vt+h_{0}[/tex]
90 = 16[tex]t^{2}[/tex] + 0
90 = 16[tex]t^{2}[/tex]
[tex]t^{2} = \frac{90}{16}[/tex]
[tex]t^{2}=5.625[/tex]
t = [tex]\sqrt{5.625}[/tex]
t = 2.45
Hence, 2.45 seconds will it take for the egg to reach the ground.
