Mathematics

Answer:

  subtract 3

Step-by-step explanation:

You want to "undo" what is done to x. It usually works well to do that in reverse order. Here, x is ...

  • multiplied by 2
  • had 3 added to the product

To undo these steps, you start by undoing the addition of 3.

__

1st step: subtract 3 from both sides.

2nd step: divide both sides by 2

_____

As with equations, whatever you do to one side of the inequality must also be done to the other side. When we say "subtract 3", we mean "subtract 3 from both sides of the inequality."

In the triangle, x is 5 greater than y, and y is 21 less than three times z, and the perimeter is 180. What is the value of each
svetlana [45]

Answer:

x = 77

y = 72

z = 31

Step-by-step explanation:

The formula for the Perimeter of triangle XYZ = x + y + z

From the question:

x + y + z = 180

In the triangle, x is 5 greater than y,

x = y + 5

y is 21 less than three times z

y = 3z - 21

3z = y + 21

z = y + 21/3

Hence:using substitution

x + y + z = 180

y + 5 + y + y/3 + 21/3 = 180

2y + y/3 + 5 + 21/3 = 180

2y + y/3 = 180 - ( 5 + 21/3)

2y + y/3 = 180 - (5 + 7)

2y + y/3 = 180 - 12

2y + y/3 = 168

Multiply both sides by 3

2y × 3 + y/3 × 3 = 168 × 3

6y + y = 504

7y = 504

y = 504/7

y = 72

Solving for x

x = y + 5

x = 72 + 5

x = 77

Solving for z

z = (y + 21)/3

z = (72 + 21)/3

z = 93/3

z = 31

Therefore,

x = 77

y = 72

z = 31

What is the surface area of the rectangle prism
AnnyKZ [126]

Answer:

310 in²

Step-by-step explanation:

The general formula for the surface area of a prism is:

SA = 2ab + 2ac + 2bc, where 'a', 'b' and 'c' are the measures of the sides.  In this case the lengths are 4 in, 5 in and 15 in.

a = 4 in

b = 5 in

c = 15 in

SA = 2(4*5) + 2(4*15) + 2(5*15)

SA = 40 + 120 + 150 = 310 in²
