How do you solve x - 1 + 5x = 23

Roman55 [17]

Answer:

X=4

Step-by-step explanation:

First you add like terms, in this case 5x and x. Then you have 6x-1=23. You then add 1 from both sides so you end up with 6x=24. This then results in X=4

gtnhenbr [62]

Answer:

The answer is 0.25

Step-by-step explanation:

(1)we group like terms by subtracting 32.50 by 28.75

(2) we subtract 20 and 5 to give us a value of 15

(3)when we subtract 32.50 and 28.75 we get a value of 3.75

(4)so the equation will look like this 3.75t = 15

(5)we divide 3.75 we both the two equations

(6)With a correct calculation, Your answer should be t = 0.25

The circumference of a bowling ball is 8pi in. Find the surface area of the bowling ball. Express your answer in terms of pi.

MrRa [10]

Surface area of a sphere (3D solid's name for ball shaped object) is given by

$SA = 4 \pi r^{2}$

We do not know the radius of the sphere but we can work it out from the circumference $8 \pi$

$Circumference = 2 \pi r$
$8 \pi =2 \pi r$
$r= \frac{8 \pi }{4 \pi }=2$

then
$SA=4 \pi (2)^{2} =16 \pi$

Solve this problem. What is x?

DedPeter [7]

a^2 + b^2 = c^2

a^2 = 6^2 + √117^2

a^2 + 36 = 117

a^2 = 117 - 36

a^2 = 81

a = √81

a = 9

x = 9
