If x + y = 5 and 3x = 2 then what you
do is:
3x = 2 and since you want the variable by itself you’d divide by 3... giving you an answer of x = 2/3 BUT YOURE NOT DONE YET
so now you plug what x equals (2/3) into the equation x + y = 5:
2/3 + y = 5
to solve this you have to subtract each side by 2/3 so x = 5 - 2/3
(5/1 - 2/3.... to get like denominators multiply the nominator and the denominator for 5/1 by 3 giving you: 15/3 - 2/3 = 13/3)
your final answer would be 13/3
Answer:
pounds.
Step-by-step explanation:
We have been given that Gina's literacy bucket weighs 6 pounds. Her novel weighs 1 4/6 pounds, and her chrome book weighs 2 1/6.
To find weight of bucket after taking out the two items, we will subtract weight of each item from 6 pounds as:
Let us convert mixed fractions into improper fractions as:
Combine numerators:
Therefore, the weight of the bucket is pounds.
Answer:
16y -25
Step-by-step explanation:
7-4[3-(4y-5)] = 7 -4(3 -4y +5) = 7 -4(-4y +8)
= 7 + 16y -32
= 16y -25
