Answer:

23: 21\frac{23}{55}  25: 1\frac{44}{45}

Step-by-step explanation:

<u>Question 23</u>:

1) add the whole numbers together: 15+5=20

2)To add fractions, both need to have the same denominator. Find a number that is a multiple of both denominators (in this case 55)

\frac{9}{11} → \frac{45}{55} (multiply the numerator and denominator by 5)

\frac{3}{5} → \frac{33}{55} (multiply the numerator and denominator by 11)

3) add the fractions together

\frac{45}{55} + \frac{33}{55} = \frac{78}{55} (add the numerators)

4) Turn the improper fraction into a mixed number

Divide 78 by 55. You'll get a whole number and a remainder. The remainder is the new numerator: In this case 55 enters 78 once with a remainder of 23. Therefore:

1\frac{23}{55}

5) Add the whole numbers together to get the final answer:

20+1= 21

Answer: 21\frac{23}{55}

<u>Question 25</u>:

Follow the above steps but subtract instead of adding

I need this answered as quickly as possible
Sonja [21]
The best estimate would be (-1)(1/2)(-1)(1)

Why?
(-4/5) = Really close to -1. The fraction -5/5 would = -1
(3/5) = Really close to 1/2
(-6/7)  = Really close to -1. It is just -1/7 from being from -1
(5/6) = Really close to 1. It is just 1/6 from being 1

Solve using the elimination method -4x-2y=-18​
Softa [21]

Step-by-step explanation:

-4x – 2y= -18

Add 2y to both sides

-4x- 2y+ 2y = -18 + 2y

Simplify

-4x = -18 + 2y

Divide both sides by -4

-4x/-4= -18/-4+ 2y/-4

simplify

x= - -9+y/2
