Ok so 5x20 is 100 and 3x20 is 60 then add 3 is 63 apps that she downloaded then 100-63 is 37 apps that she still has space for.
Answer:
They will get both get $280 if they work for 20 hrs.
Step-by-step explanation:
1) In order to solve the problem, we can use a system of equations
2)Aaliyah's salary equation: y=13x+20
Finn's salary equation: y=12x+40
3) Using the equal values method, we now know that 12x+40=13x+20
4) when you solve the equation, x=20.
5) Substitute 20 for x.
y=12X20+40
y=280
1. 44
2. 126.854
3. 9 5/12
4. so 0.00635
5. 5*5*11
6. 704
7. 4
8. 8,3'9
9. $1296
10. absolute value meas that whatever the result is in between the abolute value signs you make it positive so if 2-3 wer in absolute value signs the answer would be +1
11. prime 2=2
12. composite 9=3*3
13. prime 29=29
14. composite 51=3*17
15. composite 77=
16. prime 101=101
17. composite 231=3*7*11
18. composite 4924=2*2*1231
19. prime 1=1
20. prime 31=31
Hello!
You first make two equations
Let x stand for the price of a burger
Let y stand for the price of fries
3x + 2y = 7.15
4x + 3y = 9.93
multiply the top equation by 3 and the bottom equation by 2
9x + 6y = 21.45
8x + 6y = 19.86
You can subtract the two equations
x = 1.59
Now you can put x into one of the original equations
3(1.59) + 2y = 7.15
Combine like terms
4.77 + 2y = 7.15
Subtract 4.77 from both sides
2y = 2.38
Divide both sides by 2
y = 1.19
The answers are a burger cost $1.59 and Fries cost $1.19
Hope this helps!
