Set up an equation:

2x = 28

Divide both sides by 2

X = 14

3(14) = 42

The numbers are 42 and 14

What is 3=7(4 - 2u)-6u
alisha [4.7K]

Answer:

u = 5/4

Step-by-step explanation:

to evaluate for the value of u we would simply open the bracket and then evaluate for the value of u by collecting the like terms together.

solution

3=7(4 - 2u)-6u

3 = 28- 14u - 6u

collect the like terms

3 + 14u + 6u = 28

20u = 28 - 3

20u = 25

divide both sides by the coefficient of u which is 20

20u/20 = 25/20

u = 5/4

Please help quick! Proportions & Graphs
Triss [41]

Answer:

1. No

2. No

3. Yes

4. No

Step-by-step explanation:

The first one isn't  proportional because it doesn't  start at 0

The second one isn't proportional because there isn't  a pattern between  the coordinates

The 3rd one is a proportional relationship because it starts at 0 and there is an equal amount of space between each coordinate and there is evidentially a pattern.

Finally, the  4th one isn't proportional because the last coordinate doesn't correspond w/ the others

Plz mark me brainliest if correct :)
