Answer:
1x+ 1y =11
10x + 5y = 80
x = the cost of a taco = $5
y = the cost of a burrito = $6
Step-by-step explanation:
x = the cost of a taco
y = the cost of a burrito
1x+ 1y =11
10x + 5y = 80
rearange 1st equation as y = 11 -x and plug in into the 2nd one for y:
10x + 5( 11-x) = 80 distribute left side
10x + 55 - 5x = 80 combine like terms
10x - 5x = 5x
5x + 55 = 80 subtract 55 from both sides
5x = 80 - 55
5x = 25 divide by 5
x = 5
plug in for y in 1st equation y = 11--x =11-5 = 6
Answer:
D. AP
Step-by-step explanation:
A hypotenuse is a side of a triangle, so you can get rid of answers A and B as those are angles.
A hypotenuse is the longest side in a right triangle. You can see just by looking at the picture that AP is much longer than ZP
To solve this, subtract 8.75 from 110, then divide by 9. The answer is 11.25 each pizza. :)
Answer:
20.56 cm
Step-by-step explanation:
You would want to go by reverse order of operations. This is a one step equation. You subtract 2 on both sides, in which you will get: -14 = k.
