Answer:

8 + 4x = 28

Step-by-step explanation:

So in this equation 'x' = 5. Eight more would be 8 +. So you would subtract 8 from 28 giving you 20. From there you would divide by four giving you five thus which is your 'x' variable.

Answer: (-3,0)

To get this answer, we subtract 5 from the x coordinate and add 2 to the y coordinate. Point A is located at (x,y) = (2,-2) so we see that x = 2 and y = -2

Subtract 5 from the x coordinate: x-5 = 2-5 = -3. The new x coordinate is -3

Add 2 to the y coordinate: y+2 = -2+2 = 0. The new y coordinate is 0.

Therefore, using the rule (x,y) --> (x-5,y+2) has the mapping (2,-2) ---> (-3,0)

andre [41]

100 = 40 + 3x

Subtract 40 from each side

60 = 3x

Divide each side by 3

20 = x

The highest price of a sweatshirt can be $20

100 = 40 + 3(20)

If the unknown value is x, then x = $\frac{14}{4}$ × 6 = 21.

Explanation:

Since it is a double number line with a ratio, all the ratios of one number line to the other will remain equal for all the values along both the number lines. Assume the unknown value to be x.
The ratio of the number on the first number line to the corresponding number on the second number line is calculated to be; $\frac{7}{2}$ = $\frac{14}{4}$ = $\frac{x}{6}$ = $\frac{28}{8}$ = $\frac{35}{10}$ = 3.5. So $\frac{x}{6}$ = 3.5, x = 3.5 × 6 = 21.
We can also calculate x by the following method. As ratios are equal we can directly substitute the value to another ration. So $\frac{14}{4}$ = $\frac{x}{6}$ , x = $\frac{14}{4}$ × 6 = $\frac{84}{4}$ = 21.
