Answer:

Let’s organize what they’re asking for.

Subtract the sum of -1250 and 1138 from the sum of 1136 and 1272.

Lets first find the sun if -1250 and 1138:

-1250 + 1138 = -112

Then we’re asked to subtract that sum from the sum of 1136 and 1272. So now let’s find the sum of 1136 and 1272:

1136 + 1272 = 2408

Alright now back to what they’re asking for.

The question asks to subtract the sum of -1250 and 1138 FROM the sum of 1136 and 1272.

We’re subtracting a negative number FROM a positive number, so basically we can turn the negative number into a positive number and we will instead have an addition problem:

2408 - (-112)

The -112 will change to a +112

so now we have an addition problem.

2408 + 112 = 2520

<u>The answer to your question is 2,520</u>

A recipe for casserole calls for 2 cups of rice. The recipe makes 6 servings of casserole. how many cups of rice will you need t
ss7ja [257]

You will need 3.333.... cups of rice to make 10 servings of casserole.

<u><em>Explanation</em></u>

The recipe which makes 6 servings of casserole, needs 2 cups of rice.

Suppose, you need x cups of rice for making 10 servings of casserole.

Now, the equation according to <u>the ratio of "cups of rice" to the "servings of casserole" </u>will be.....

\frac{x}{10}=\frac{2}{6}\\ \\ 6x= 2*10=20\\ \\ x=\frac{20}{6}=3.333.....

So, you will need 3.333.... cups of rice to make 10 servings of casserole.

Pleas help me answer this. Question 2 please.
tamaranim1 [39]

Answer: A

We could solve it but it's easier to just check the given solutions.

A. (7,1)

2y + 5 = 2(1)+5 = 7 = x, good

x/3-y = 7/3 - 1 = 4/3, good

B. (-3,8)

2y + 5 = 2(8)+5 = 21 not x=-3, doesn't check

C. Can't be true because we found a solution

D.  Infinitely many solutions not true because the lines have different slopes

4/5 minus 1/3 plz i need help
IRISSAK [1]

Answer:

7/15

Step-by-step explanation:

Step 1

We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.

So we multiply 4 by 3, and get 12.

Then we multiply 1 by 5, and get 5.

Next we give both terms new denominators -- 5 × 3 = 15.

So now our fractions look like this:

12

15

−  

5

15

Step 2

Since our denominators match, we can subtract the numerators.

12 − 5 = 7

So the answer is:

7

15

Step 3

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

To find out, we try dividing it by 2...

Nope! So now we try the next greatest prime number, 3...

Nope! So now we try the next greatest prime number, 5...

Nope! So now we try the next greatest prime number, 7...

Nope! So now we try the next greatest prime number, 11...

No good. 11 is larger than 7. So we're done reducing.
