First, I will made 4 1/2 into the decimal which is 4.5. Then, I add 6 with 4.5 to find the total fabric that Belinda will buy which is 10.5 in total. As a result, Belinda buys total 10.5 white and red fabrics.
Answer:
27, 30, 33
Step-by-step explanation:
Since Sam has fewer number of baseball cards than Jill who has 36 baseball cards and can arrange all his cards in only three ways, the possible number of baseball cards that Sam could have is 27, 30 or 33.
If he has 27 baseball cards, he can arrange 9 baseball cards per row in 3 rows
If he has 30 baseball cards, he can arrange 10 baseball cards per row in 3 rows
If he has 33 baseball cards, he can arrange 11 baseball cards per row in 3 rows
I will go about solving this using the elimination method.
First, convert the equations.
10x + y = -20
4x + y = -12
Second, find the easiest variable to get rid of and get rid of it! (In this case, y) We will subtract to get rid of y.
6x = -8
Third, you want to solve the equation.
6x = -8 (divide by 6)
x =
![-1 \frac{1}{3}](https://tex.z-dn.net/?f=-1%20%5Cfrac%7B1%7D%7B3%7D%20)
Fourth, solve for y by inserting the answer for x into one of the equations.
10(
![-1 \frac{1}{3}](https://tex.z-dn.net/?f=-1%20%5Cfrac%7B1%7D%7B3%7D%20)
) + y = -20
![-13 \frac{1}{3}](https://tex.z-dn.net/?f=-13%20%5Cfrac%7B1%7D%7B3%7D%20)
+ y = -20 (subtract
![-13 \frac{1}{3}](https://tex.z-dn.net/?f=-13%20%5Cfrac%7B1%7D%7B3%7D%20)
)
y =
![-6 \frac{2}{3}](https://tex.z-dn.net/?f=-6%20%5Cfrac%7B2%7D%7B3%7D%20)
The solution for this system of equations is (
![-1 \frac{1}{3}](https://tex.z-dn.net/?f=-1%20%5Cfrac%7B1%7D%7B3%7D%20)
,
![-6 \frac{2}{3}](https://tex.z-dn.net/?f=-6%20%5Cfrac%7B2%7D%7B3%7D%20)
).
Photo please? and a function means that it cant have the same number of x axis'
example,
function;
15 6
-46 37
36 -37
27 -25
not a function;
-1 3
5 7
-5 6
-1 8
