?
Step-by-step explanation:
1 foot = 12 inches.
35 feet x 12 = 420 inches.
Divide total inches by people:
420 / 20 = 21
Each student gets 21 inches of ribbon.
Answer:
Step-by-step explanation:
y = 1/8x - 1.....sub this back in for y in the other equation
-5x + 4y = -13
-5x + 4(1/8x - 1) = -13
-5x + 1/2x - 4 = -13.....multiple everything by 2 to get rid of the fraction
-5x(2) + 1/2x(2) - 4(2) = -13(2)
-10x + 1x - 8 = - 26
- 9x = -26 + 8
-9x = - 18
x = 18/9
x = 2.....now sub 2 in for x in either of the original equations to find y
y = 1/8x - 1
y = 1/8(2) - 1
y = 1/4 - 4/4
y = -3/4
so ur solution is : (2,-3/4) <===
The car gets 46 miles per gallon in the city.
Divide total miles driven in th city by miles per gallon to find total number of gallons of gas used:
10,000 miles / 46 miles per gallon = 217.3913 gallons of gas used.
Now multiply gallons used by price per gallon:
217.3913 x $1.75 = $380.43 per year
-3
Because -2^2-8+1
-2to the second power is 4
4-8=-4
-4+1=-3
