Answer:True,because there are two or more variable/numbers in there
Step-by-step explanation:
Answer:
x=−2
Step-by-step explanation: Step 1: Simplify both sides of the equation.
3(x−5)−3=5(x−2)+2x
(3)(x)+(3)(−5)+−3=(5)(x)+(5)(−2)+2x(Distribute)
3x+−15+−3=5x+−10+2x
(3x)+(−15+−3)=(5x+2x)+(−10)(Combine Like Terms)
3x+−18=7x+−10
3x−18=7x−10
Step 2: Subtract 7x from both sides.
3x−18−7x=7x−10−7x
−4x−18=−10
Step 3: Add 18 to both sides.
−4x−18+18=−10+18
−4x=8
Step 4: Divide both sides by -4.
−4x
−4
=
8
−4
x=−2
Answer:
782.5inch³
Step-by-step explanation:
<u>The question is on volume of a prism and that of a cylinder</u>
<u>Finding the volume of the prism</u>
V=Bh where B is the base area and h is the height
Base area=14"×14"=196 inch²
height =8"
v=196×8= 1568 in³
<u>Finding volume of the cylinder</u>
v=
r²h where r is the radius of cylinder and h is the height of cylinder
r=10/2=5 inches and h=10 inches
v=3.142×5×5×10=785.5inch³
<u>The difference in volume</u>
Difference in volume=1568-785.5=782.5inch³
The two marked angles are complementary angles. This means that the angles are equal.
Hence, X + 1 = 2X - 3.
By rearranging, X = 4.
