a.
y = -30 ... x = 15
y = 60 ... x = ?
-------------------------------
-30 * x = 15 * 60
x = - 15 * 60 / 30
x = -30

b.
y = 8 ... x = 3
y = ? ... x = 45
-------------------------
8 * 45 = y * 3
y = 8 * 45 / 3
y = 120

c.
x = -6 ... y = ?
x = -5 ... y = 15
-------------------------
-6 * 15 = -5 * y
y = 6 * 15 / 5

(5ab-9a-4) - (-4ab + 5)
qaws [65]

Answer:

9ab - 9a +1

Step-by-step explanation:

first, we can distribute the negative sign to the second set of parentheses.

-(-4ab + 5) becomes + 4ab - 5

now let's put the values in (5ab-9a-4) side by side with the corresponding values in + 4ab - 5

5ab + 4ab - 9a - 4 - 5

= 9ab - 9a - 9, because 5ab + 4ab = 9ab, -9a is alone, and -4 - 5 = -9.

Please answer 2 and 3 !!
Usimov [2.4K]

(2) So we know Ethan uses 1/4 cup of milk for his cake. And if he needs to make 3 times the amount of 1 cake, he'll make 3 cakes today. So we multiply the amount of cakes (3) by the amount of milk needed (1/4)

3 * 1/4 = 3/4

Ethan will need 3/4 cups of milk.

(3) We know Isabella need's 2/5 of a gallon of the food to make 1 gallon.

She want's to make 5 gallons, so like the other problem, we multiply the amount of gallons (5) by the amount of food needed (2/5):

5 * 2/5 = 10/5 = 2/1.

Isabella will need 2 gallons of food.
