Question

What is the value of x in the equation 7x + 2y=48, when y= 3? x
Пох = 6
- ох=7
ox = 8
ох= 9

Solution 1

**Answer:**

x = 6

**Step-by-step explanation:**

Given

7x + 2y = 48 ← substitute y = 3 into the equation

7x + 2(3) = 48, that is

7x + 6 = 48 ( subtract 6 from both sides )

7x = 42 ( divide both sides by 7 )

x = 6

Solution 2

**Answer:**

A. x = 6

Question

Jasmijn is a pet groomer. She charges n dollars to clip a dog's nails, w dollars to wash the dog, and h dollars to cut a dog's hair, Jasmijn will perform all three services for each of the 4 dogs she needs to groom this
weekend
Which expressions can we use to describe how much Jasmijn will charge for grooming all 4 dogs?

Solution 1

**Answer:**

(n + w + h) x 4

**Step-by-step explanation:**

First, you would have to add up the total for one day, (n + w + h) and once that total is found, multiply it for each day Jasmine will work, in this case, its 4; so (n + w + h) x 4 will be your answer.

Question

Solution 1

**Question:**

Madison and Allie have a goal to read 3,300 pages together by the end of 3rd quarter. Madison reads 50 page every day Allie reads 10 more pages every day than Madison reads. Write and solve an equation to show how many days it will take them to read 3,300 pages

**Answer:**

It will take** 30 days** for them to read 3,300 pages

**Step-by-step explanation:**

**Given:**

The total number of pages to be read = 3300 pages

Number of pages Madison reads = 50 page every day

Number of pages Allie reads = 1 0 more pages every day than Madison reads

**To Find:**

Total Number of days needed to read 3300 pages = ?

**Solution:**

Let the number days they will take be x

then

Number of pages Madison read per day (x) + Number of pages Allie read per day(x) = 3300

(50)x + (50 +10) x = 3300

50x + 60x = 3300

110x = 5500

x =

**x = 30**

Question

Find the stationary points on the curve y = (3x – 1)(x - 2)^4.

Solution 1

**Step-by-step explanation:**

by using y=uv derivative formula and stationary mean y' = 0

y' = 3(x–2)⁴ + 3(3x–1)(x–2)³ = 0

cancel 3 and factorize

(x–2+3x–1)(x–2)³ = 0

x = ¾ or x = 2

we got point and (2,0)

Question

A store sells second-hand goods at 40% off the recommended retail price. For a lawn mower
valued at $369:
a What is the selling price?

Solution 1

**Answer:**

$221.4

**Step-by-step explanation:**

So there are two ways that you can solve this problem.

1) multiply $369 by 40% (or .4) to get 147.6 and then subtract 369-147.6=$221.4

2) multiply $369 by 60% (or .6) to get $221.4

Solution 2

**Answer:**

The selling price is $221.40

**Step-by-step explanation:**

So you first want to find what is 40% of the retail price ($369). So divide by 10 to get 10% ($36.90) and then multiply by 4 to get 40% ($147.60). Now that you have 40% subtract that by the retail price. $369 - $147.60= $221.40

Question

Tyler tried to solve an equation step by step. 3(x + 4) = -18

Step 3
Find Tyler's mistake.

Solution 1

**Answer:**

**Step-by-step explanation:**
