Explain how the following inequality can be used to find the number of toys you can afford to buy. 150≤ 11x + 10 ≤ 450

irakobra [83]

Answer:

The maximum number of toys you can afford to buy is 40

Step-by-step explanation:

Let

x -----> the number of toys

we have the compound inequality

$150\leq 11x+10\leq 450$

Divide into two inequalities

$150\leq 11x+10$ -----> inequality A

$11x+10\leq 450$ ----> inequality B

Solve the inequality A

$150-10\leq 11x$

$140\leq 11x$

Divide by 11 both sides

$12.7\leq x$

Rewrite

$x\geq 12.7$

Solve the inequality B

$11x\leq 450-10$

$11x\leq 440$

Divide by 11 both sides

$x\leq 40$

The solution for x is the interval ----> [13,40}

Remember that the number of toys must be a whole number

The domain is all whole numbers greater than or equal to 13 toys and less than or equal to 40 toys

therefore

The maximum number of toys you can afford to buy is 40

12. Complete the comparison: 3+7>? O A. 7 + 3 O B. 9 + 4 O C. 10-2 O D. 8 +2.

Sever21 [200]

Answer: C. 10-2

3+7 = 10
So you need to find which value is less than ten

A is wrong because 7+3= 10 and 10 is not less than 10
B is wrong because 9+4 = 11 and 11 is not less than 10
D is wrong because 10-2 = 10 and 10 is not less than 10

C is right because 10-2 =8 and 8 is less than 10

Mr Avery Needs to repaint the outside of his house. He estimates that the area he needs to paint is about 1600 Each gallon of pa

Tju [1.3M]

Answer:

Mr. Avery will need to buy 5.4 gallons of paint.

Step-by-step explanation:

We have been given that Mr. Avery estimates that the area he needs to paint is about 1600 and each gallon of paint will cover about 250 sq feet.

So to find the number of gallons of paint needed to paint the outside of house we will divide total area to be painted (1600 sq. ft) by area covered by gallon of paint.

$\text{The number of gallon required to paint}=\frac{\text{Area of the house to be painted}}{\text{Area painted by 1 gallon of paint}}$

Since Mr. Avery has 1 gallon of paint left over from the last time he painted that he can use this time, so Mr. Avery will need one gallon less. We can represent this information as:

$\text{The number of gallon required to paint}=\frac{\text{Area of the house to be painted}}{\text{Area painted by 1 gallon of paint}}-1$
