156÷13
13 goes into 15 once
so under the 156 put 13 under 15 left with 2 bring down the 6 to make it 26
13 goes into 26 2 times
so under where you wrote 26 put 26 then 26-26=0
so your answer is 12
You can use elimination
x - y = 7
0.5x + y = 5
1.5x = 12
x = 8
Then plug in x into one of the original equations
8 - y = 7
y = 1
Solution is (8,1)
Breanna used
pounds of clay for her project.
Step-by-step explanation:
Step 1; First, we must convert the mixed fractions into improper fractions. To do that we multiply the whole number with the denominator and add with it the numerator while the denominator remains the same. To convert this fraction 1
, we multiply 1 with 8 and then add 4 and keep the 8 as the denominator so we get
1
= (1 × 8) + 5 / 8 =
.
Step 2; After conversion, it's just a matter of subtraction. To calculate the clay she used for her project, we subtract the clay she had after from the clay she had before doing the project. While subtracting two fractions, if denominators are equal we subtract the numerators and keep the denominator the same.

So Breanna used
