Answer:

564 tiles

Step-by-step explanation:

there are many ways to solve this soo...

1. convert to centimetres (there are 100 centimetres in 1 metre)

2. the square tiles area = 20*20=400cm

2. find the large area (4.8m x 3.8m or 480cm x 380cm)

480 *380=182400cm

2. find the two smaller areas (1.2m x 1.8m or 120cm x 180cm)

2(120*180)=4.3200cm

3. add to find total area

182400 +43200=225600cm

4. find how many tiles are needed

\frac{225600}{400}= 564 tiles

The measures of two supplementary angles are (4x + 8) and (6x + 3)º.
Illusion [34]

Step-by-step explanation:

A supplementary angle is an angle that is 180 degrees. We are given two angles that add up to 180, but we need to solve for x first.

The first step is to solve both angles. We know that both angles added together are supplementary, so they are equal to 180.

4x + 8 = unknown angle

6x + 3 = unknown angle

(4x + 8) + (6x + 3) = 180

Because we know a supplementary angle is 180 degrees, we can solve for x to find both angles.

Solve for x.

(4x + 8) + (6x + 3) = 180

10x + 11 = 180

10x = 169

x = 16.9

Now, we know the value of x, so we plug in x for both angles to determine which angle is smaller.

4x + 8

4(16.9) + 8

67.6 + 8 = 75.6 degrees

and the other angle

6x + 3

6(16.9) + 3

101.4 + 3 = 104.4 degrees

Now we know that the smaller angle is 75.6 degrees.

Also, to make sure the math is correct, when plugging in both numbers after finding x, they should add to 180.

75.6 + 104.4 = 180 so we know they are supplementary for sure.

Good luck!

Use the substitution methods to solve the system of equations. Choose the correct ordered pair. y=7x+8 y=x+20
krek1111 [17]

Answer:

d

Step-by-step explanation:

Solution by substitution method

y=7x+8

∴y-7x=8

and y=x+20

∴y-x=20

Suppose,

-7x+y=8→(1)

and -x+y=20→(2)

Taking equation (1), we have

-7x+y=8

⇒y=7x+8→(3)

Putting y=7x+8 in equation (2), we get

-x + 7x + 8 = 20

6x = 20-8

6x = 12

x= 12 / 6

x = 2

substitute for x in equation (3)

y = 7(x) + 8

y = 7(2) + 8

y = 22

X - 3 = 7 pls help step by step explanation
PtichkaEL [24]

Answer:

x = 10

Step-by-step explanation:

First, to solve for x, you need to isolate the variable, meaning that it needs to be the only term on one side of the equation. To do this, we'll just cancel out the -3 by adding +3 on both sides of our equation.

x - 3 = 7

 +3    +3

x = 10

Leaving us with our answer, x = 10

Hope this helped :)
