Answer:
2044 cups
Step-by-step explanation:
In a quart, there are 4 cups:
1 quart = 4 cups
In 512 quarts, there will be:
4 * 512 cups = 2048 cups
If only 4 cups remained after watering, then the number of cups used to water the plants is:
2048 - 4 = 2044 cups
2.75 * 12 = 33.
If the Sanchez family is using 2 3/4 (or 2.75) tubes of toothpaste and there are 12 months in a year, we use the equation above and get 33 as our answer.
Answer:
5;5 and 65; they are congruent
X-y=-10
x=-10-y
7x+7y=-14
7(-10-y)+7y=-14
-70-7y+7y=-14
0y=56
y=0
x=-10-y
x=-10-0
x=-10
I’m not 100% sure if this is right, so I hope someone checks this over :)
