The answer is: x<12

Steps by steps

5(x+5)<85

Divide each term by 5 and simplify.

5(x+5)÷5<85÷5

Reduce the expression by cancelling the common factors.

x+5<85÷5

Divide 85 by 5.

x+5<17

Move all terms NOT containing "x" to the right side of the inequality.

Subtract 5 from both sides of the inequality.

x<-5+17

Add -5 and 17.

=x<12

juin [17]

This is equal tio the diameter of the circle formed:-

152 ins = circumference and this = pi * diameter

so the Answer is 152 / pi = 48.4 ins to nearest tenth

48 inches to nearest inch.

Answer:

Step-by-step explanation:

The step shown indicates that y was eliminated from the equations. For choices A, B, D, this is done by adding the equations together (the y-coefficients are opposites). The result of doing that gives x-terms of 4x, 0x, and 0x, respectively. These x-terms do not match the one given: 2x.

For choice C, the y-term is eliminated by subtracting twice the second equation from the first. Doing that gives ...

(4x +2y) -2(x +y) = (14) -2(3)

4x +2y -2x -2y = 14 -6 . . . . eliminate parentheses

2x = 8 . . . . . . . . . . . . . . collect terms

A Square was altered so that one side is increased by 9 inches in the other side is decreased by 2 inches.The area of the result

LekaFEV [45]

Let s represent the length of any one side of the original square. The longer side of the resulting rectangle is s + 9 and the shorter side s - 2.

The area of this rectangle is (s+9)(s-2) = 60 in^2.

This is a quadratic equation and can be solved using various methods. Let's rewrite this equation in standard form: s^2 + 7s - 18 = 60, or:

s^2 + 7s - 78 = 0. This factors as follows: (s+13)(s-6)=0, so that s = -13 and s= 6. Discard s = -13, since the side length cannot be negative. Then s = 6, and the area of the original square was 36 in^2.
