x + y = 12
Equation 2: Difference:
x - y = 4
Solution:
x + y = 12
x - y = 4
-------------
Add the two equations together:
2x = 16
Divide both sides by 2:
x = 8
Solve for y:
Use equation 1 substituting for x:
x + y = 12
8 + y = 12
Subtract 8 from both sides:
y = 4
Answer:
one number is 8 and the other number is 4.
8 + 4 = 12
8 - 4 = 4

Answer:
120 tiny cubes
Step-by-step explanation:
Find the volume of both the tiny cubes and the big cube. Then we will take big volume cube and divide it by tiny cube volume.
So big cube has volume (5/3*4/3*2)=40/9 cm^3
Tiny cube volume is (1/3*1/3*1/3)=1/27 cm^3
(40/9) divided by (1/27)
is the same as 40/9 time 27=40(27)/9=40(3)=120
We know that the puppy weights 56 ounces and it tells us that 1 pound = 16 ounces so every 16 ounces we have a pound. It wants to know how many pounds does the puppy weights. 56 / 16 = number of pounds. So 56 divided by 16 = pounds. The puppy weights 3.5 pounds
Answer:
3x-1
Step-by-step explanation:
Answer:
times 5/4
Step-by-step explanation:
7 x = 35/4
x = (35/4) / 7
x = (35/4) x (1/7)
x = 35/28
x = 5/4
