The temperature was 5 degrees below zero in the morning. By the afternoon, it increased by 12 degrees. What is the temperature?
**SHOW YOUR WORK

Answers

Answer:

7 degrees (above zero)

Step-by-step explanation:

-5 + 12 = 7

or on a number line plat at -5 and count 12 to the right and you end on +7

Well... You didn't specify whether or not it is Farenheight or Celsius, So im going to show both.

Farenheight:

-5 + 12 = 7

Because

... A simple breaking way to show it would be: 12-5=7    -5+5=0   0+7 = 7

Celsius:

Its the same :)

If you were going to convert it to Farenheight though:

-5 Celsius = 23* Farenheight.

12 Celsius = 53.6* Farenheight

 23

+56.3

=-------

79.3

Solve the system using substitution. Show your work.
x = -4y + 9
x - y = 4

Answers

Answer:

please what should we found? is it the value of ×or y

x = -4y + 9
x - y = 4

- rearrange the second equation to x = 4 + y
- then we can plug it into x for the first equation

4 + y = -4y + 9 — then we solve for y
y = -4y + 5
5y = 5 -> y = 1

we can then plug in 1 (our y value) into the original second equation.

x - 1 = 4 -> x = 5

x = 5 & y = 1
you should put it in a coordinate layout so:
(5,1)

1. If it takes 1/3 to make a scarf then you can make 3 with one yard of fabric and since there are five you do 3 times 5 to make 15.

2. Since you want to build 8 and you can't use the wood you cut up already. All you need is eight because each board makes 1 birdhouse.

3. If there are 12 then you take 3/4 on all of them you get 12 but then you have some left over and then you get 4 more 3/4 which makes your answer 16.

4. If you un-simplify 3/4 you get 6/8 and half of 6/8 is 3/8 which is your answer.

For her science fair project, Madelyn is growing crystals with sugar water. She wants to know if the size of the container affects crystal growth. To start, Madelyn pours a sugar-water mixture into a small bowl. Then she pours triple the amount of the mixture into a large bucket. She decides to add red coloring so the crystals are more visible. Madelyn adds the same amount of red coloring to both containers. Which container's sugar-water mixture is a darker shade of red?
no links

Answers

If the bowl mixture is 3 time smaller than the bucket mixture and she added the same amount of color

The smaller container of sugar-water mixture will have the darker shade of red.

What are arithmetic operations?

The four basic operations of arithmetic can be used to add, subtract, multiply, or divide two or even more quantities.

They cover topics like the study of integers and the order of operations, which are relevant to all other areas of mathematics including algebra, data processing, and geometry.

As per the given information in the question,

The experiment done by Madelyn is that,

Firstly, she has a small bowl where she pours as sugar-water mixture and in second case she pours tripe the amount of the mixture into a large bucket.

She adds the same amount of red coloring to both containers, then the smaller container or the small bowl will get the darker shade of red because the amount of mixture is less over there and the amount of color is same so, if you put the color in the larger one it will not get that red as compared to the smaller bowl.
