on 60!! Hope this help's
Step-by-step explanation:
The value of x is 7 because 8/24 = 1/3 so find 1/3 of 21
Difference of two squares will be
16y^2 -x^2 = (4y -x)(4y +x)
so the second choice
Answer:
x = 4
y = 1
Step-by-step explanation:
x = 3y + 1 (Multiply everything by -2)
2x + 4y = 12 (Transfer 4y to the right of the = sign)
2x = -4y + 12
-2x = -6y - 2
0 = -10y + 10
-10 = -10y
y = 1
x = 3y + 1
x = 3(1) + 1
x = 3 + 1
x = 4
Answer:
0 boxes minimum
Step-by-step explanation:
The mass of the truck and paper must satisfy ...
