Answer:
pizza: $4, coke: $3, chips: $2
Step-by-step explanation:
Lets make the price of a pizza=p a coke= k and a bag of chips=c
then we have the following equations
p+k+c=9
p+2k=10
2p+2c=12
Because p is common in all the equations we shall make it the subject of each equation.
p=9-(k+c)...........i
p=10-2k..............ii
p=6-c...................iii
We then equate i and iii
9-(k+c)=6-c
9-k-c=6-c
putting like terms together we get:
9-6=-c+c+k
1 coke, k=$3
replacing this value in equation ii
we get p=10-2(3)
p=10-6= 4
1 pizza, p=$4
replacing this value in equation iii
4=6-c
c=6-4
=2
a bag of chips, c=$2
Thus, a pizza, a coke and a bag of chips= pizza: $4, coke: $3, chips: $2
Answer:
the line will pass through yellow and red
Firstly, you should find how many square yard is in one square foot.
One square yard= Nine square feet.
then, in order to find the area, you need to multiply 12 by 8, which gives you 96 square feet.
In order to find the square feet, you need to divide 96 by 9 (as 1 square yard is equal to 9 square feet)
When you divide these, you get 10.66
Therefore, Amy needs 10.66 square yards of carpet.
Hope this helps :)
