If it’s proportional, then when X is 1, y is 2.6, you get that by dividing 275.5 by 29

so when y is 408.5, x is 156.91

I believe that is correct.

There are 3,785 milliliters in 1 gallon, and there are 4 quarts in 1 gallon. For each question, explain or show reasoning.
Novay_Z [31]

Answer:

There are 11,355 milliliters in 3 gallons, and 946.25 milliliters in 1 quart.

Step-by-step explanation:

If there are 3,785 milliliters in 1 gallon, multiply each side by 3 because you want the product to equal 3 gallons.3,785 times 3 is equal to 11,355, and 1 times 3 is 3. So, 3 gallons are equal to 11,355 milliliters. If there are 3,785 milliliters in 1 gallon, and there are 4 quarts in 1 gallon, that means that there are 3,785 milliliters in 4 quarts. Now, you want to find the amount of milliliters in 1 quart so you should divide both the 3,785 and the 4 by 4. So, there are 946.25 milliliters in 1 quart.

Which ordered pairs in the form (x, y) are solutions to the equation (x + 7)y = 10? Choose all answers that are correct.  A.(−9,
Elanso [62]
What you do is to substitute the first number for x and the second for y:

(x+7)y=10

a):

(-9+7)*-5=10
(-2)*-5=10
10=10

yes, it's a solution!

b)
(-8+7)10=10
-1*10=10
-10=10

no, not a solution!

c) (-2+7)2=10
5*2=10
yes, a solution!!

d) (3+7)*5=10
50=10

no, not a solution!
