Step-by-step explanation:

Depending on how many games he has played that number where the x is. So let’s say he plays two games so what you’re going to do is plug the two in for the X so then it would be 2×3 which is 6 then you would do 6+5 because you still have the 5 left and it says to add.

Answer:

x = 35/2

Step-by-step explanation:

add: (6/7)x = 8 + 7

(6/7)x = 15

multiply by the reciprocal

x = 15(7/6)

Simplify

x = 5(7/2)

multiply:

x = 35/2

Check:

(6/7)(35/2)  -8 = 7

let the value be x, then the equation is:

x = -8 + (-10)

x = - 8 - 10

x = - 10

the distance of the sum from -8 is the distance between -8 & -10, i.e -8 - (-10) = 2.

Answers

Answer:  x = 480

Steps: x/2.4 + 39 = 239

Subtract 39 from both sides: x/2.4 + 39 - 39 = 239 - 39

Simplify: x/2.4 = 200

Multiply both sides by 2.4: x/2.4  ×  2.4 = 200 ×  2.4

Simplify: x = 480

-123

Step-by-step explanation:

This is the answer because:

1) First, multiply the negative sign with the positive sign.

Negative x Positive = Negative

Equation: -77 - 46

2) Now, multiply the negative sign with the negative sign.

Negative x Negative =  Positive

Equation: 77 + 46 = 123

3) Finally, add the greater number's sign (-77) in front of the number.

Three times a number increased by one is between negative eight and seven find all the numbers.

All the numbers that makes the statement true are given by?

Please hurry this is on my exam

Answers

This is about absolute value inequalities.

The set of possible values of x that make the statement true are; x = {-2, -1, 0, 1}

Let the number in the question be x.

We are told that when it is multiplied by 3 and 1 added to it, it is between - 8 and 7. This means it is greater than -8 but less than 7.

Thus;

3x + 1 > -8  - - - (eq 1)

3x + 1 < 7  - - - (eq 2)

Let's find range of x from eq 1;

3x + 1 > -8

Subtract 1 from both sides to get;

3x > -9

x > -9/3

x > -3

Similarly, let's find the range of x from eq 2;

3x + 1 < 7

Subtract 1 from both sides to get;

3x < 7 - 1

3x < 6

x < 6/3

x < 2

Thus, we can write that;

-3 < x < 2

Thus, the set of possible values of x are; x = {-2, -1, 0, 1}
