25 pints are in 7.5 quarts
This would be simplified as following: r^2 t^4
Answer:
4) divide, 5) multiply, 5) divide
Step-by-step explanation:
4) you need to divide to determine the length each individual ribbon will be
5) you need to multiply the price of one shirt by three to find the price of three shirts
6) you need to divide the amount of dog food the dog will eat each day by the amount of dog food to see how many days the food will last.
Well I cannot tell you the answer but here are the steps to answering this question:
1. Subtraction needs to be 2 fractions with the same denominators so the way to do that is to find the factors and pick any that is the same factors for both numbers (it doesn't matter because whatever one you pick, you will get different answers but equivalent fractions which is still correct)
2. subtract only the numerators (the top number) but NOT the denominators (the bottom number) because if you do that, you will get 0 as the denominator and that gives you a negative number and that is a totally wrong answer
3. The sum is your answer!
hope you understood!
Just tell me if you didn't understand and I can tell you in a different way that is easier for you.
The answer is <span>2(–4y + 13) – 3y = –29
Step 1: Express </span><span>x from the second equation
Step 2: Substitute x into the first equation:
The system of equations is:
</span><span>2x – 3y = –29
x + 4y = 13
Step 1:
</span>The second equation is: x + 4y = 13
Rearrange it to get x: x = - 4y + 13
Step 2:
The first equation is: 2x – 3y = –29
The second equation is: x = - 4y + 13
Substitute x from the second equation into the first one:
2(-4y + 13) - 3y = -29
Therefore, the second choice is correct.
