C.) 2 is the right answer

Step-by-step explanation:

Given

-15(x-__)=25

We can see in the next step

-15x+30=25

We can check by substituting each option one by one

So,

A.) -30

-15(x-(-30))=25\\-15(x+30)=25\\-15x-150=25

We can see that by putting -30 we don't get the expression given in the picture so it is not the right answer.

B.) -2

-15(x-(-2))=25\\-15(x+2)=25\\-15x-30=25

We can see that by putting -2 we don't get the expression given in the picture so it is not the right answer.

C.) 2

-15(x-2)=25\\-15x+30=25

We get the same expression by putting 2 in the blank so it is the right answer.

Hence,

C.) 2 is the right answer

Tresset [83]

Given :   Isaac is purchasing two pairs of shoes—one pair for $37.00 and the second pair for $42.00. The state sales tax applied to Isaac’s bill is 7%.

To Find : How much is Isaac’s total bill?  

b) 25% discount off  before tax

Solution:

one pair for $37.00

second pair for $42.00

Total Bill before taxes = 37 + 42 =  79 $

7 % Sale Tax = (7/100)79 = 5.53 $

Isaac’s total bill = 79 +  5.53  = 84.53  $

Total Bill before taxes = 37 + 42 =  79 $

Discount 25 % = (25/100)79 = 19.75$

Total Bill before taxes = 79 - 19.75 = 59.25 $

7 % Sale Tax = (7/100)59.25 =4.1475 $

Isaac’s total bill = 59.25  +  4.1475  = 63.3975  $

The ratio of the sides of a triangle is 2 6 7 if the perimeter of the triangle is 195 meters​
timama [110]

Answer: 91m

Step-by-step explanation:

We set three sides of the triangle equal to 2x,6x,7x; because there is the ratio 2:6:7, which x is a common factor of these three sides.

P = a + b + c

2x + 6x + 7x = 195

    15x = 195

        x = 13

7x suppose be the longest side of the triangle, we plug in 13 for x, then:

7x = 7(13) = 91 m
