You multiply both of the equations until you have two of the same term the same like for example, say I have 4x and 5x. You want to multiply until both have the same number, so multiply 5x by four, then multiply 4x by five, and you will get 20x, then both of those cancel out and you will be left with the other variable, and you just solve like a normal equation.
If $0.35=1 ounce
?=8.5 ounces
8.5/1*$0.35=$2.975 Therefore 8.5 ounces cost $2.975
If 1 ounce =$0.35
12.2 ounces=?
12.2/1*$0.35=$4.27
Therefore 12.2 ounces cost $4.27
Answer:
(3(6)-1)/(2(6)+1)
Step-by-step explanation:
See attached image.
Answer:
y=11
Step-by-step explanation:
To isolate the variable, y, you need to divide by 13 on both sides. 13y/13 cancels out, so you are left with 143/13. 143 ÷ 13 is 11, so y = 11.
To Check your answer:
Substitute y for 11. Your equation will be 143 = 13 x 11. Does 13 x 11 = 143? Yes.
Answer:
9 pounds weight on moon
Step-by-step explanation:
Given
Variation: Direct
<u>Buzz Adrin</u>
Earth = 360 pounds
Moon = 60 pounds
Required
Determine the weight of 54 pounds
The given parameters can be summarized as:
360 pounds Earth = 60 pounds Moon
54 pounds Earth = x pounds Moon
To solve for x, we start by using cross multiplication:
Divide through by 360
