Answer:
x-7
Step-by-step explanation:
7x - 18 = 10x + 3
Subtract 7x from each side
7x-7x - 18 = 10x-7x + 3
-18 = 3x+3
Subtract 3 from each side
-18-3 = 3x
-21 = 3x
Divide by 3
-21/3 =3x/3
-7=x
Well first of all if I had a multiplication question such as 12,000×1000 of course you would know it would be 12,000 well you would always use your place value chart saying ones tens hundreds thousands and thousands and hundreds
The sides of the frame are (12+2x) and (6+2x).
Its area A is 112.
Therefore by equating:
(12+2x)*(6+2x)=112
you can get the answer for x. You will obtain a quadratic equation you have to solve.
Answer:
y-11=43(x+2)
Step-by-step explanation:
y-y1=m(x-x1)
y-11=43(x-(-2))
y-11=43(x+2)
Answer:
62.8 units
Step-by-step explanation:
The formula for a cylinder πr²h. R being the radius and h being the height.
Therefore, plug in the numbers and solve.
π(2)²(5) = 20π = 62.8 units
