answer:
x = 0.80
y = 1.50
step-by-step explanation:
x = cost of tacos
y = cost of burritos
both equations:
3x + 2y = 5.40
2x + 1y = 3.10
^
turn this | into this |
v
y = 3.10 - 2x
then add it to the equation :
3x + 2 [ 3.10 - 2x ] = 5.40
3x + 6.2 - 4x = 5.40
-1x = - 0.8
x= 0.80
then add x = 0.80 to the equations to get :
3 [ 0.80 ] + 2y = 5.40
2.4 + 2y = 5.40
2y = 3
y = 1.5
Answer:
angle 1=90, angle 2=110,angle 3=120, angle 4=90, angle 5=39
Step-by-step explanation:
Answer:
85 feet
Step-by-step explanation:
60^2+60^2=7200
square root of 7200 is 85
5 is 3x less than 15 so you find 3x less than 18 to get 18/3 or 6ft... so your answer is B. Hope this helps
