Answer:

(22, 5)

Step-by-step explanation:

Given the 2 equations

x = y + 17 → (1)

x = 4y + 2 → (2)

Substitute x = 4y + 2 into (1)

4y + 2 = y + 17 ( subtract y from both sides )

3y + 2 = 17 ( subtract 2 from both sides )

3y = 15 ( divide both sides by 3 )

y = 5

Substitute y = 5 into either (1) or (2) and solve for x

(1) : x = 5 + 17 = 22

Solution is (22, 5)

What is the measure of angle B in the triangle? Enter your answer in the box.
eduard
The triangle angle-sum theorem says that all those angles added together equal 180.  Therefore, 120+x+x+16=180 and 2x+136=180 and 2x=44.  Therefore, x = 22, which is angle B.

Find the miing value in the ratio table. Then write the equivalent ratio. Plum 14 42 Grape 7 3 24 The equivalent ratio are 14 :
denis-greek [22]

The equivalent ratio is 8 : 4.

And the missing values are as follows 21, 6 and 48.

Complete table be,

Plum     14   42   6   48

Grape    7    21    3    24

Given, a ratio table

Plum     14   42   __   __

Grape    7    __    3    24

we have to find the missing values and the equivalent ratios.

in the first ratio,

Plum : Grape = 14 : 7 = 2 : 1

Now, in the second ratio,

2 : 1 = 42 : __

x = 21

Now, in the third ratio,

2 : 1 = __ : 3

x = 6

Now, in the forth ratio,

2 : 1 = __ : 24

x = 48

So, the equivalent ratio is 8 : 4.

And the missing values are as follows 21, 6 and 48.

Hence, the equivalent ratio is 8 : 4.

And the missing values are as follows 21, 6 and 48.

Complete table be,

Plum     14   42   6   48

Grape    7    21    3    24
