Division property of equality

Answers

Answer 1
The answer is Division property of equality. This is because at Step 3, you have to divide to get your final answer. It cannot be the other ones because you do not subtract or distribute in step 3.

Find the value of x and y

Answers

Answer:

x = 80, y = 122

Step-by-step explanation:

I got this equation by using vertical angles to create a complimentary angle pair (they sum to 90 degrees).

3/4x+2/5x-2=90°,

23/20x - 2=90°,

23/20x = 92°,

92/(23/20)

20/(1/4)

20(4)

= 80.

Since the angles are a linear pair on the left side(they sum to 180 degrees). Just subtract 180 from 3/4x-2 and substitute x into the expression.

180-(3/4(x)-2), 180-3/4(80)+2 = 120+2 = 122

Step-by-step explanation:

Again Lol ima copy and paste my same answer.

Hey there!

Let's write this as a ratio/proportion.

The sum of this basic ratio is 4.25.

To figure out how much of each we have for 34, we divide this 34 by 4.25, our sum of the two ingredients. This will give us a factor we can multiply our two ingredient measurements by.

34/4.25=8

Now, we multiply our two ingredients by eight.

2.75(8)=22

1.5(8)=12

Note that these two add up to make 34 tablespoons.

Therefore, we have...

22 tablespoons of olive oil and 12 tablespoons of balsamic vinegar were used in the 34 tablespoons of bread dip.

Which size can of soup shown in the table has the lowest unit price? ​

Answers

Answer.
Explanation. Let’s get all of the options down to the 1 ounce unit to determine the price per oz. we can do this by dividing the cost by the size.
0.79/10= 0.079 per oz
1.29/15=0.086 per oz
2.16/18=0.12 per oz
3.19/32=0.099 per oz
By looking at all of the options, we find that the 10 oz can has the lowest unit price. Hope this helps, let me know if it’s correct so others can use it :)
Good luck.

The can of size 10 has the lowest unit price.

What is Unit Rate?

Unit rate is the amount of one quantity for a unit amount of the other quantity.

In other words it compares 1 unit of some quantity with different amount of another quantity.

We have to find the unit rate.

For size 10 :

Cost of 10 oz of soup = $0.79

Cost of 1 oz of soup = 0.79 / 10 = 0.079

For size 15 :

Cost of 15 oz of soup = $1.29

Cost of 1 oz of soup = 1.29 / 15 = $0.086

For size 18 :

Cost of 18 oz of soup = $2.16

Cost of 1 oz of soup = 2.16 / 18 = $0.12

For size 32 :

Cost of 32 oz of soup = $3.19

Cost of 1 oz of soup = 3.19 / 32 = $0.0997

The smallest unit price is for can of size 10.

Hence the lowest unit price is for the can of size 10.
