Answer: C

Step-by-step explanation:

First set greater than 300 since Zack has to make more than 300 to make a profit. The equation is the amount he makes (n) - cost of supplies ($32.50). He is completing 4 rooms so multiply (n - 32.5) with 4.

The equation would be 4 (n - 32.5)>300

Now to solve for n, divide 4 on other sides, then add 32.5 to both sides.

What is the slope. Please help.

Answers

The answer is 5 . 5 is the slope

Answer:

The slope is 5

Step-by-step explanation:

Our equation:

y = mx + b

Given equation:

y = 5x + 4

Now, let's compare both equations to see which is the slope.

=> y = mx + b = y = 5x + 4

We can clearly see that m = 5.

Therefore, the slope is 5.

How long does it take for Han and Tyler to meet?
Explain or show your reasoning.

Answers

First, you can add up 4+2 to get 6 because they’re both rates.

Next, divide 18 by 6 and you get 3.

So, it will take three hours for the boys to meet up.

One way to check your answer is to multiply 4x3=12 and 2x3=6 and 12+6 is 18.

The family likes peaches and other fruits. The local farmer’s market is selling fresh peaches at a discounted price. If the farmer’s market sold 35% of its produce and has 280 peaches remaining, how many peaches did it originally have on hand? Show all your work and explain how you used equivalent ratios to solve the problem. (2 points)

Answers

Answer:

Sorry for the super late answer but here:

Step-by-step explanation:

If it sold 35% and now there is 280 remaining, that means that they produce 280 x 135%. That is also equal to 280 x 1.35. The equation is equal to 378 remaining. Please give me brainiest if you see this. However, it is ok if not since this is a super late answer plus I didn't use equivalent ratios.

Step-by-step explanation:

Combine like terms:

[tex]\sf 3\left(v+5\right)=3v-4[/tex]

Expand:

Subtract 15 from both sides:

[tex]\sf 3v+15-15=3v-4-15[/tex]

[tex]\sf 3v=3v-19[/tex]

Subtract 3v from both sides:

Subtract 15 from both sides:

Subtract 2v from both sides:

Subtract 15 from both sides:

Subtract 2v from both sides:

N'(-10,-15) is the image of N after a dilation with a scale factor of 5/4, centered at the origin. What are the coordinates of N?

Answers

When the point N is dilated, the coordinate of N changes to N'

The coordinate of point N is (8,12)

How to determine the coordinate of N

The given parameters are:

N' = (10,15)

k = 5/4

To calculate the coordinate of N, we make use of:

N * k = N'

So, we have:

N * 5/4 = (10,15)

Multiply both sides by 4

N * 5 = (40,60)

Divide both sides by 5

N = (8,12)

Hence, the coordinate of point N is (8,12)
