4(x+8)
because 4 is the greatest common factor of 4 and 32. you distribute the 4 into the parenthesis and get 4x+32
Answer:
9.8x + 1.1y + 9.9z
Step-by-step explanation:
⇒ 5.5x + 6.2y + 4.3x + 8.3z + 1.6z - 5.1y
⇒ 9.8x + 1.1y + 9.9z
Answer:
On the highway, the cost to drive per mile is $2.21
Step-by-step explanation:
In the city the average distance per gallon is 15 miles
On the highway, he can drive 47% farther;
The distance he can cover on the highway per gallon will be;
15 + 47% of 15
= 15 + 0.47(15)
= 15 + 7.05 = 22.05
So on the highway, he can travel a distance of 22.05 miles
So the cost per mile on the highway would be;
$3.25 for 15 miles
$x for 22.05 miles
so we have the cost to drive per mile on the highway as;
(3.25 * 15)/22.05 = $2.21
Answer:
minus a negative number meand that u are adding its inverse so the equation would look like 4d+1=13. from there u isolate d
4d+1=13
-1 -1
4d=12
d=3
Hello!
We must use a certain formula to find the circumference of a circle. The formula is:
C = 2 × pi × r
We have the diameter of the circle, so we'll be able to find its radius, since radius is always half the diameter.
r = d ÷ 2
r = 9 ÷ 2
r = 4.5
So, the radius of the circle is 4.5 centimetres. Pi equals approximately 3.14. Substitute:
C = 2 × 3.14 × 4.5
C = 6.28 × 4.5
C = 28.26
ANSWER:
The circumference of the circle is 28.26 centimetres long.
