Answer:

1. e ≥ -2

2. c ≤ 4

3. x < 1.5 or 1 5/10

Step-by-step explanation:

1.  -3e-10 ≤ -4  => first add 10 to both sides

     +10    +10

-3e ≤ 6 => Then divide negative three on both sides.

/-3    /-3

e ≥ -2 => Since, we divided by a negative the sign switches.

2.  8c+4 ≤ 4(c-3) => First, Distribute the 4.

8c+4 ≤ 4c -12 => Next, Subtract 4 on both sides.

8c ≤ 4c -16 => then, subtract 4c on both sides.

-4c   4c

4c ≤ 16 => Finally, you divided 4 on both sides.

/4    /4

c ≤ 4

3. 5(x-1) < 3x +10 -8x => First, you add like terms.

5(x -1) < -5x +10 => Next, you distribute the 5.

5x -5 < -5x +10 => Then, you add five in both sides.

    +5      +5

5x < -5x +15 => After that you add -5x in both sides.

+5x   +5x

10x < 15 => Finally, you divide 10 in both sides.

/10     /10

x < 1.5 or 1 5/10

The sum of two numbers is 17. One number is 7 less than the other. What are the two numbers?
lions [1.4K]

Answer:

5 and 12

Step-by-step explanation:

First, set up an equation. Since it says that one number is 7 less than the other, we can use x for the number that is 7 less than the other number, and x+7 to represent the other number. We set the equation equal to 17 because the question says that the sum of two numbers is 17.

x+x+7=17

Then, you solve the equation:

x+x+7=17

2x+7=17

2x=10

x=5.

So, the number that is 7 less than the other number is 5. To find the other number, we would add 7 to 5 because the other number would be 7 more than 5.

7+5=12

The two numbers are 5 and 12.

tekilochka [14]
If you would like to solve for x, you can do this using the following steps:

7x + 15 = 38
7x = 38 - 15
7x = 23
x = 23/7

The correct result would be 23/7.
