What is the absolute value? What symbol represents absolute value?

Answers

Answer:

Absolute value is the distance the number away is from 0. In simpler terms, if you had a -8 the absolute value is 8. I attached a picture of the absolute value symbols. The absolute value of a normal positive 8 is still 8 though because it's the same distance on a number line.

The most common way to represent the absolute value of a number or expression is to surround it with the absolute value symbol: two vertical straight lines. |6| = 6 means “the absolute value of 6 is 6.” |–6| = 6 means “the absolute value of –6 is 6.” |–2 – x| means “the absolute value of the expression –2 minus x

Create a scatterplot displaying the data in the table. Be sure to include a linear trend line. (2 points)

b. y - 4 = 30

c. s + 2s = 36

d. t - t + 4t = 16

e. 5a = 15

f. 8x - x = 21

Answers

A) x + 8 = 28

x = 28 - 8

x = 20

B) y - 4 = 30

y = 30 + 4

y = 34

C) s + 2s = 36

3s = 36

s = 12

D) t - t + 4t = 16

4t = 16

t = 4

E) 5a = 15

a = 3

F) 8x - x = 21

7x = 21

x = 3

Han and Tyler both started walking toward each other from opposite ends of a 18-mile path. Han walks at a pace of 4 miles per hour and Tyler walks at a pace of 2 miles per hour.
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.

Lucy wants to decorate the curved surface of a trash can that has a radius of 4 in. and a height of 12 in.

What is the area of the curved surface of the trash can she will need to decorate?

A trash can with radius 4 inches and height 12 inches.

Answers

12 in =30 cm

4 in = 10 cm

area of 1 circle= 3.14×10×10= 314 cm²

area of 2 circle= 314×2= 628 cm²

if u unfold the trash can the biggest surface(not the circle) will become a rectangle with two circles(628 cm²)

length of rectangle = circle circumference

= 2×3.14×10

=62.8 cm

area of rectangle= 62.8 × 30 = 1884 cm²

total area= 1884 + 628 = 2512 cm²

Answer:

2512 cm²

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.
