Please solve what n is on paper please

Answers

Answer 1

Answer:

7 - 6 (1- 7n) = 127

7 - 6 - 42n = 127

1 - 42n = 127

subtract 1 from both sides

- 42n = 126

divide both sides by -42

n = 3

What is greater
5/6 or 3/8

Answers

Convert both of them into a decimal, and the decimal closest to a a whole number is the greater one.

5/6
= (5*4) / (6*4)
= 20/24

3/8
= (3*3) / (8*3)
= 9/24

Because 20/24 > 9/24, 5/6 is greater than 3/8~

Answers

to solve -56 - (-27.07) we have to remember that a negative sign in front of another negative sign will change the sign to a positive and -(-27.07)=27.07
-56+27.07=- 28.93
YOUR CHOICE IS B

-56-(-27.07)
-56+27.07
-28.93

Four tickets would cost $30. If you get the price of 2 tickets ($15) then multiply it by 2 then you will get your answer ;)

30.00 You multiply 7.50 * 4 and it gives you 30

a composite figure is formed by combining a square and a triangle its total area is 32.5 ft2 the area of the triangle is 7.5 ft2 what is the length of each side of the square

Answers

The length of each side of the square is 5ft

Area of a composite function

Area of the composite figure = area of square + area of a triangle

Substitute the given information

32.5 = Area of square + 7.5

Area of square = 32.5 - 7.5

Area of squar = 25.0 ft^2

Since Area of square = L^2

L = 5ft

Hence the length of each side of the square is 5ft
