Answer:

a. 2x -3

b. 7

Step-by-step explanation:

a. The expression that represents the difference is sales between the two sales will be:

9x - (7x + 3) = 9x - 7x - 3 = 2x - 3

b. What we do here is to simply substitute the value of 5 for x

mathematically, we have to substitute the value of 5 in the expression above

We have this as:

2(5) -3

= 10-3 = 7

20pts how do you solve 3x-2y=14?

Furkat [3]

X(3) - Y(2) = 14. So you need numbers that will multiply by 3 and a number that multiply by 2 that will equal 14.
The x can be 10 (equals 30) and then y can be 8 (equals 16).
30 subtracted by 16 equals 14.

ANSWER:

X = 10 Y = 16
3(10) - 2(8) = 14

Point x is at 2/3 on a number line. On the same number line, point y is at the same distance from 0 as a point x, but has a nume

BaLLatris [955]

Answer:

The denominator is 12

$\displaystyle y=-\frac{8}{12}$

Step-by-step explanation:

The Number Line

We can represent any real number in a properly segmented line, where the zero-mark is the separation between positive numbers to its right side and negative numbers to the left side.

We are given the number x = 2/3. Since it's positive, its location lies to the right of the zero but before the 1 as shown in the figure below.

We want to locate a second point y at the same distance from 0 as the point x, so we have two options: y is the same as x, or y is negative at the same distance from zero. We chose the last option.

Its numerator must be 8, so we need to multiply it by 4. But we cannot alter the value of x, so we must also multiply the denominator by 4, which gives us the fraction 8/12, but recall it must be negative.

$\boxed{\displaystyle y=-\frac{8}{12}}$
