Answers

Answer 1

Answer:

The total length of the purple ribbon and pink ribbon is $1(11)/(15)$ .

Given that, Noelle has 5/6 of a yard of purple ribbon and 9/10 of a yard of pink ribbon.

What is addition of two fractions?

To add fractions there are three simple steps:

Step 1: Make sure the bottom numbers (the denominators) are the same. Step 2: Add the top numbers (the numerators), put that answer over the denominator.

Step 3: Simplify the fraction (if possible)

Total number of yards of ribbon

= 5/6 + 9/10

LCM of denominators 6 and 10 is 30

Now, 25/30 + 27/30

= 52/30

= $1 (22)/(30) =1(11)/(15)$

Therefore, the total length of the purple ribbon and pink ribbon is $1(11)/(15)$ .

Answer 2

Answer: add 5/6 and 9/10
first look for a common denominator....that's....30
so now the fractions are 25/30 + 27/30
add the numerators keep the common denominator.
52/30 in mixed number is 1 22/30, now reduce the fraction, divide by 2, so
1 11/15, so Noelle has 1 11/15 ribbon altogether.

rasheed needs to save $231 to earn money he plans to wash cars and charge $12 per car write to estimates rasheed could use to determine how many cars he needs to wash

Answers

Rasheed needs to wash 20 cars as washing 19 cars won't be $231.

What is an equation?

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Given, Rasheed needs to save $231 to earn money he plans to wash cars and charge $12 per car.

Assuming no. of cars he needs to wash is x.

∴ 12x = 231.

x = 231/12.

x = 19.25.

But he needs to wash 20 cars to meet his needs.

How do you do 3b+7.1=2.5b+11.5

Answers

3b+7.1=2.5b+11.5

First, you'd take 2.5b and subtract it from 3b

3b-2.5b+7.1=11.5

Simplify:

.5b+7.1=11.5

then, you would take 7.1, and since it is positive, subtract it from 11.5

.5b=11.5-7.1

Simplify:

.5b=4.4

Lastly, you'd take 4.4 and divide it by .5, leaving the unknown factor alone.

b=4.4/.5

Final answer:

b=8.8
