Answer:
Y=2.37
Step-by-step explanation;
Make the top equation solve for x, x=3-y
subsitute (x=3-y) into 7x-y=-3
Get 7(3-y)-y=-3
use the distributive property and get 21-7y-y=-3
Combine like terms 21-8y=-3
Subtract 21 on both sides, -8y=-19
Divide by -8 on both sides
y=2.37
The density of an object is what i can’t see the question
The anwser is C.The probability that event A occurs, given that event B occurs, is 83%. i just took the test
7/8 pounds of red apples
15/16 pounds of green apples
7/8 + 15/16
Find the common denominator: 2 convert 7/8
7/8 x 2 = 14/16
14/16 + 15/16 = 29/16 or 1 13/16 pounds of total apples
