b + p = 14 and 0.80 b + 2 p = 20.80 are the system of equations.
Step-by-step explanation:
Step 1 :
Let b be the number of bananas
Let p be the number of peaches
Given that the total of bananas and peaches that Emily bought = 14
Hence we have,
b + p = 14
Step 2 :
Cost of one banana = $0.80
Cost of one peach = $2
Cost of all the bananas and peaches Emily bought = $20.80
So sum of b bananas costing $0.80 and sum of p peaches costing $2 each is $20.80
Hence we have
0.80 b +2 p = 20.80
Solving for the above 2 equations we can get the value for b and p which will give the number of bananas and peaches bought
Step 3 :
Answer :
The system of equations that could be used to find the number of the bananas and the number of the peaches that Emily bought is given by
b + p = 14
0.80 b +2 p = 20.80
Answer:
30 Boxes can be made
Step-by-step explanation:
7x+12
8x+3
Because it is a horizontal line the two angles must add up to 180°
So add the two angles up together and set it equal to 180°
7x+12+8x+3=180
Add the two x’s 7x+8x=15x
Add the constants 12+3=15
You get 15x+15=180
Now subtract 15 from both sides
15x=165
Now divide by 15 to get x
X=11
