Two angles are vertical angles. One angle is ( 8x + 15 ) and the other angle is 143. Solve for x.
sineoko [7]

Answer:

x = 16

Step-by-step explanation:

Verticle angles are always congruent, so:

(8x + 15) = 143

Now, we can solve to isolate x:

8x + 15 - 15 = 143 - 15  (subtract 15 from both sides)

8x/8 = 128/8                (divide both sides by 8)

x = 16

You can always plug in the value of x to the original equation to check your answer:

8(16) + 15 = 143

3/4 of a number is 27. What’s the number?
Artyom0805 [142]

Hello from MrBillDoesMath!

Answer:

36


Discussion:

From the problem statement

(3/4) x = 27

where "x" is the number to be found.

Multiply both side of the above equation by (4/3):

(4/3)(3/4)x = 27 (4/3) =>                            as (4/3)(3/4) = 1

1x = 27 * 4/3 = 108/3 = 36



Thank you,

MrB
