Answer:

B) Only (-2, 9)

Step-by-step explanation:

To find out which of the given options is the solution to the linear equation, y = -2x + 5:

We can substitute the values of the given options to see whether they provide a true statement.

A) (2, -9):

y = -2x + 5

-9 = -2(2) + 5

-9 = -4 + 5

-9 = 1 (False statement. Therefore, this option is not included as a solution).

B) Only (-2, 9):

9 = -2(-2) + 5

9 = 4 + 5

9 = 9 (<u>True statement</u>. Thus, (-2, 9) is a solution to the given linear equation).

We no longer have to test options C and D because we already tested (2, -9) and determined that it's not a solution.

Therefore, the correct answer is option B) Only (-2, 9).

Item 20 A rectangular school banner has a length of 54 inches and a width of 36 inches. A sign is made that is similar to the sc
siniylev [52]

Answer:

The ratio of the area of the school banner to the area of the sign is <u>1944 cubic inches : 192.61 cubic inches.</u>

Step-by-step explanation:

Given:

A rectangular school banner has a length of 54 inches and a width of 36 inches. A sign is made that is similar to the school banner and has a length of 17 inches.

Now, to find the ratio of the area of the school banner to the area of the sign.

Dimensions of school banner :

Length = 54 inches.

Width = 36 inches.

Dimension of school sign:

Length = 17 inches.

So, to we find the width of sign by using cross multiplication method:

Let the width be x.

So, 54 is equivalent to 36.

Thus, 17 is equivalent to x.

\frac{54}{36} =\frac{17}{x}

By cross multiplying we get:

54x=612

Dividing both sides by 54 we get:

x=11.33\ inches.

Thus, the width of sign = 11.33 inches.

Now, to get the ratio of the area of the school banner to the area of the sign:

Area of the school banner : Area of the school sign.

= 54\times 36:17\times 11.33

= 1944:192.61

Therefore, the ratio of the area of the school banner to the area of the sign is 1944 cubic inches : 192.61 cubic inches.

Plz help me schools basically here for me
nevsk [136]

Here's what i did:

I broke down the fraction entirely.

3 / 5 = 6 / 10

divide 6 by two and divide 18 by two. This makes 3 / 10 = 9.

divide 3 by three and 9 by three, making 1 / 10 = 3.

if you need 7 / 10 of the number (30) then do 3*7.

The answer is 21.
