Your friend really wants to buy the newest cell phone which will cost him $750. He gets a job detailing cars and SUVs and plans to save all the money he earns. If he gets paid $55 to detail a car and $70 to detail an SUV, what linear inequality can be used to determine how many of each he must detail in order to earn at least $750?
A: 55c+70x [tex]\leq[/tex] 750
B: 55c+70x > 750
C: 55c+70x [tex]\geq[/tex] 750
D: 55c+70x < 750

Answers

Answer 1

Answer:

C, 55c + 70x  ≥ 750

Step-by-step explanation:

He needs a minimum of $750.

Answer 2

The equation 55c + 70x 750 can be used to calculate how many of each he needs detail in order to make at least $750. The right answer is A.

What is inequality?

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.

Given that,

Number of cars = c

Number of SUVs = x

Amount paid for detailed car = $55

Amount paid for detailed SUV = $70

Cost of coolest cellphone = $750

The inequality for the given data will be written as below,

(Amount paid for detailed car × Number of cars) + (Amount paid for detailed SUV × Number of SUV) ≤ Cost of coolest cellphone

55c + 70x ≤ 750

Therefore, the equation 55c + 70x 750 can be used to calculate how many of each he needs detail in order to make at least $750. The right answer is A.

Answer:

Y=112  x=45

Step-by-step explanation:

y+68=180

so 180-68=112

y=112

y+(4x-2)+30=180

112+(4x-2)+30=180

140+4x=180

-140 to both sides

4x=180

Answer:

x = .1

Step-by-step explanation:

Multiply 5 times x and 5 times 2

You end up with this: 10x + 10 = 11

Then, subtract 10 on each side so you would get 10x = 1

Finally, divide 10 into 1 to get your answer of x = .1

2 option 2
3 28.5
4 175
5 224

1. A kite has a width to length ratio of 4:5, so let the width be 4x and the length be 5x. We know that the length is 80 cm. 80 = 5x

Divide by 5.

16 = x.

Now, the width is 4x.

16 times 4 is 64.

The width is 64.

2. Find the unit rate for each juice. The unit rate is ml / dollar.

The first juice has a unit rate of 150 / 1.

The second has a unit rate of 500 / 1.75.

The third has a rate of 1000 / 4.

The fourth has a rate of 2000 / 7.25

Put all values into a calculator. (First: 150, Second: 285.714285, Third: 250, Fourth: 275.862068966)

Whichever one can buy the most ml for a dollar is the best buy.

In here, that is the SECOND rate, which is 1.75 for 500 ml.

She earns 3% commission on all her sales, so if s represents her sales, she'd earn .03s. Inhere, she sells $950 in total. That is her total sales.

So you plug $950 into the equation as s.

.03 (950) = 28.5

She earned $28.50.

Poor Maya!

3. You set it up in ratios. She needs 250 mL of milk for every 325 mL of pancake mix. 250 milk / 325 mix.

But she only has 225 mix.

So you set up 250 milk / 325 mix = M milk / 225 mix

As in all proportions, you cross multiply.

250 x 225 = 325 x M

56250 = 325M

Divide by 325 on both sides.

173.076923077 = M

She needs about 175 mL. The fourth choice.

4. There are a total of 1120 spectators, made of only home team fans and visiting team fans.

There is a total of 100% of people, and 80% are supporters of the home team, so to find the supporters of the visiting team you subtract 100% by 80%.

100 - 80 = 20.

So 20% of the spectators are supporters of visiting team. Now 20% of the total, and 20% = .20.

.20 x 1120 = 224

224 people are fans of the visiting team.

5. A 500-mL bottle of insect repellent has 22 mg of DEET, a chemical used to keep mosquitos away. The same insect repellent sells in 710-mL bottles. Which of the following proportions can be used to find the amount of DEET in the larger bottle? *

If a 500 mL bottle has 22mg of DEET, then 500ml / 22mg

So set up the equation 500 / 22 = 710 / x

Now, cross multiply.

500x = 710 times 22.

500x = 15620

Divide by 500.

x = 31.24

Other possible proportions are:

22 / x = 500 / 710

x / 22 = 710 / 500

22 / 500 = x / 710

Kayla paid $27.50 for a pair of gloves. The cost of the gloves is $8.75 more than the cost of a scarf. Which equation can be used to find the cost of the scarf?

Answers

Answer:

You can use subtraction

Step-by-step explanation:

$27.50 - $8.75 = $18.75 (cost of scarf)

-----------------------------------------------------------------------

the gloves cost 27.50 dollars and if the scarf cost 8.75 dollrs more then that means that if we subtract that extra mount we should get the price of the scarf

if $18.75 is the cost of scarf and if gloves are $8.75 more then...

$18.75 (scarf) + $8.75 (extra $) = $27.50 (gloves)
