Two more than a ceetain number is 15 less than the product of 7/8 and the number

-136

Step-by-step explanation:

Let the unknown number be written as x

2 more than the number is written as

x + 2

7/8 of the same number is written as 7/8x

15 less than that is written as

7/8x - 15

therefore

x + 2 = 7/8x - 15

collecting like terms

x - 7/8x = -15-2

1/8x = -17

x = -17*8/1

x = -136

the answer is c. 23/3

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
