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
Based on her on training regiment, Amanda will be able to run 26 miles in the 25th week.
<h3 /><h3>What is the total number of miles Amanda will run every week?</h3>
Amanda will run 2 miles in the first week and then 1 less mile in the following week. Then 3 more miles in the week after.
Week 1 - 2 miles
Week 2:
= 2 - 1
= 1 mile
Week 3:
= 1 + 3
= 4 miles
Week 4:
= 4 - 1
= 3 miles
Week 5:
= 3 + 3
= 6 miles
From the given pattern, Amanda increase the number of miles ran by 2 miles every 2 weeks.
The number of miles ran every other week would therefore be:
Week 7 = 8 miles
Week 9 = 10 miles
Week 11 = 12 miles
Week 15 = 16 miles
Week 19 = 20 miles
Week 25 = 26 miles
In conclusion, she would reach her goal in 25 weeks.

1800 laps in 12 weeks
1800/12 = 150 laps in 1 week
150/5 = 30 laps a day
30 laps in 45 minutes
x laps in 60 minutes
x = (30*60)/45 = 40 laps per hour
The triangle G'H'I' is congruent to MNO because they have two angles and the included side equal, therefore, the congruence criteria is ASA.
Answer: ASA
Answer:
85-86%
Step-by-step explanation:
Make it an equation
You want to find the percent out of a hundred, so 42 is 100 since it is all of the questions and 36 is the unknown percent X
36/42 = X/100
36 X
42 100
Cross multiply
Do math and solve for X
36 x 100 = 42 x X
3600=42X
X=85.71
