Please help solve 5/6r = 4 3/5

1 answer:

8 0

First, what I like to do is to deal with improper fractions. So I'm going to change 4 3/5 to 23/5.

5/6r = 23/5

Now all you have to do is to divide both sides by 5/6, because you want the r variable by itself. You can divide fractions just by inverting and multiplying.

5/6r • 6/5 = 23/5 • 6/5

r = 138/25

However, that is an improper fraction, so I'll change it back into a mixed number for you!

r = 5 13/25

At a bake sale there were 90 items sold total. If 42 of the items sold were cookies and the rest were brownies what is the ratio

kari74 [83]

Firstly, you do 90 - 42 to get the amount of brownies sold, which is 48. Then, you put 42 and 48 into a ratio like 42:48. After that, all you need to do is simplify to get 7:8.

1.)Painting Jane is painting one wall of her living room. The wall is rectangular, 13 feet wide by 9 feet high. What is the area

antiseptic1488 [7]

Answer:

1. $117 ft^{2}$

2. $54 ft^{2}$

3. $1,428 ft^{2}$

4. $644 ft^{2}$

5. $4,700 ft^{2}$

6. $57,600 ft^{2}$

Step-by-step explanation:

First use $A = w*l$

$w = width$

$l = length$

It doesn't have to be $A = w*l$ , it could be $A = l*w$ . It will be the same answer.

1. $3 ft * 9 ft = 117 ft^{2}$

2. $3 ft * 18 ft = 54 ft^{2}$

3. $42 ft * 34 ft = 1,428 ft^{2}$

4. $23 ft * 28 ft = 644 ft^{2}$

5. $94 ft * 50 ft = 4,700 ft^{2}$

6. $360 ft*160 ft = 57,600 ft^{2}$

Answer:

x >-8

Step-by-step explanation:

22−2x<38

Subtract 22 from each side

22-22−2x<38-22

-2x < 16

Divide each side by -2, remembering to flip the inequality

-2x/-2 > 16/-2

x >-8
