Answer:

The answer is -8/3.

Step-by-step explanation:

First, you have to make y the subject :

8x + 3y = 9

3y = -8x + 9

y = (-8/3)x + 3

In a linear equation, y = mx + b, m represent gradient (slope). So in this equation the slope is -8/3.

5|2x - 3| + 4 = 9 How do you solve this

agasfer [191]

Answer:

x = 2, or x = -1

Step-by-step explanation:

If 2x - 3 is inside the parenthesis (), then the value of x is 2.

If 2x - 3 is inside the absolute value sign, then the value of x will probably be -1.

Solution 1

(10x-15) + 4 = 9

10x -11 = 9

10x = 20 -> x = 2

Solution 2 (Not 100% sure)

|10x -15| +4 = 9

10x + 15 +4 = 9

10x + 19 = 9

10x = -10 -> x = -1

Please correct me if I'm wrong.

The number of customers in a store on the first day is represented by: (6x - 3) The number of customers on the second day is rep

Scorpion4ik [409]

Answer:the expression is 5x - 2

Step-by-step explanation:

The number of customers in a store on the first day is represented by: (6x - 3).

The number of customers on the second day is represented by: (x - 1)

An expression to find how many more customers visited the store on the first day would be the difference between the number of customers that visited the store on the first day and the number of customers that visited the store on the second day. The expression becomes

6x - 3 - (x - 1)

= 6x - 3 - x + 1

= 6x - x - 3 + 1

= 5x - 2

There will be 7 people at a party.If each person will eat 5/8 of a pound of chicken, how many pounds of chicken are needed?

vagabundo [1.1K]

Answer:

4 $\frac{3}{8}$ pounds of chicken

Step-by-step explanation:

To make the 7 a fraction we put a one under it. Then we multiple the tops of the two fractions together and the bottom two numbers of the fraction together:

$\frac{7}{1} X \frac{5}{8}$ = $\frac{35}{8}$

Finally, we simplify the improper fraction into a mixed number:

4 $\frac{3}{8}$
