Answers

Answer:

-4 + -6 = -10

Step-by-step explanation:

you just have to start at the negative four and count up to the number negative ten, then you think “how many spaces are there between four and ten? SIX. so you just take six and turn it negative, boom.

Answer:

-4 + -6 = -10.

Step-by-step explanation:

let's think of it with positive numbers, you'd get 4+6=10. now turn them into negative numbers, now you're still adding, but you're getting a lesser number. the only way this happens is when you add negative (or MINUS) numbers.

What are the answers to these questions??

Answers

Answer:

1) c and d

2) 44

3) a and c

1: if 96 is the 100% price and 32% is what you need to find, it is 32 out of 100. 0.32 is the same, as well as 32/100.

2: if you divide the shape into different pieces, i find it easier to find the area. 9 x 3 = 27. 4 x 2= 8. 3 x 3 = 9. 27+8+9=44.

3: the ratio 8:20 can be simplified down to 2:5 which makes A true. if the ratio is originally blue:red, then for c, 10:4 is the same as 4:10 since it states red to blue instead of blue to red, meaning c is also true.

Answer:

1. C and D.

2. 34

3. A and C

Step-by-step explanation:

1. All you have to do is solve each equation in order to see which ones are equal to the same answer

A. 32 * 96 = 3072

B. 3.2 * 96 = 307.2

C. 0.32 * 96 = 30.72

D. 32/100 * 96 = 30.72

Both C and D have the same answer.

2. Add up all the sides

9+6+5+4+3+3+2+2= 34

3. Look at each answer carefully.

A. There are 2 blue cubes for every 5 red cubes. True

B. When the game has 56 cubes in all, there are 40 red cubes. False

C. The ratio of red to blue cubes is 10:4. True

D. The ratio of all cubes to blue is 28:20. False

Answers

Answer:

just do this 24.76min. 23.24 then see what u have got for

Answer:

c - 23.24 = 24.76 (the first option)

48 cookies

Explanation:

Profit is equal to revenue(amount made) minus costs, or r - cost = p. The revenue is 1*cookies sold, or c. So, c - 23.24 = 24.76.

Solving is relatively simple,

c - 23.24 = 24.76

c = 48 (add 23.34 to both sides)

A-15 pound bag of bird food cost $11.70. A 20-pound bag of the same bird food costs $15.80. Which bag of bird food is the better buy?

Answers

Answer:

$11.70

Step-by-step explanation:

I think it's $11.70 because it's more cheaper.

The 15 pound bag is the better buy because you would only be paying .78 cents a pound, the 20 pound would be .79 cents a pound.
