**Step-by-step explanation:**

Jenny has 50 square tiles she arranges the tiles into a rectangular array of 4 rows how many tiles will be left over

Compact and oversized tires are produced on two different machines. The table shows the number of each type of tire produced, y, depending on the number of hours, x, the machines work.

Subtract each terms.

2.7 - 1.5 = 1.2

3.9 - 2.7 = 1.2

From these, we can see that they add 1.2 each time. 8.7 is the last number, so each numbers in the sequence is.

1.5, 2.7, 3.9, 5.1, 6.3, 7.5, 8.7

Add all of these numbers together.

1.5 + 2.7 + 3.9 + 5.1 + 6.3 + 7.5 + 8.7 = 35.7

**35.7** is your answer

hope this helps

**Answer:**

5 hours.

**Step-by-step explanation:**

let they meet after t hours.

310t+380t=3450

690t=3450

69t=345

t=345/69=5

**Answer:**

1,260

**Step-by-step explanation:**

Let's name

*LT = number of long term parking spaces*

*ST = number of short term parking spaces*

*CP = the number of parking spaces in the cell phone parking*

We have

*LT/ST = 5/7*

*ST/CP = 8/9 or CP/ST = 9/8*

*LT + ST + CP = 3180*

Dividing the last equation by ST we get

LT/ST + 1 + CP/ST = 3180/ST

replacing

5/7 + 1 + 9/8 = 3180/ST

Solving for ST we obtain *ST = 1,120.*

Replacing in the second equation, we get CP/1,120 = 9/8,

hence **CP = 1,260**

**Answer:**

x = 115° , y = 140° , z = 40°

**Step-by-step explanation:**

40° , x and 25° lie on a straight line and sum to 180° , that is

x + 40° + 25° = 180°

x + 65° = 180° ( subtract 65° from both sides )

x = 115°

z and 40° are vertically opposite angles and are congruent , then

z = 40°

y and z lie on a straight line and sum to 180° , that is

y + 40° = 180° ( subtract 40° from both sides )

y = 140°
