1) Set up an equation for the total, with T representing Trevor and M representing Marissa:
T + M = 26
2) Use the provided information related Marissa's t-shirts to Trevor's to solve for one variable at a time (in this case, T):
M = T-6
3) Substitute M with this equation into the initial, first equation:
T + (T-6) = 26
4) Combine like terms and isolate T:
T+T = 26 + 6
2T = 32
T = 16
5) Therefore, you now know that Trevor has 16 t-shirts. To find the number of t-shirts that Marissa has, simply plug in this amount for T into the equation that was already set up for M:
M = T - 6
M = 16 - 6
M = 10
Therefore, Trevor has 16 t-shirts and Marissa has 10 t-shirts.

Answer:
37 pages per hour
Step-by-step explanation:
Given that :
Time Given to read = 45 minutes ; 45 / 60 = 0.75
Number of pages readable ad by Davida within the given time frame = 27 3/4 pages
David's reading rate in pages per hour :
Number of pages read / time taken (hrs)
[27 3/4] ÷ (45/60)
[111 / 4] ÷ (45/60)
(111 / 4 ) * (60/45)
(111 * 60) / (4 * 45)
6660 / 180
= 37 pages per hour
4(2x-4)^2 - 3
4(4x^2 - 2(4)(2x) + 16) - 3
4(4x^2 -16x + 16) - 3
16x^2 - 32x + 32 - 3
16x^2 - 32x + 29
Answer:
x =
Step-by-step explanation:
Multiply all terms in the equation by the lowest common multiple of 3 and 5, that is 15. This will eliminate the fractions in the equation
10(1 - 2x) - 30x = - 6 + 20(2 - 3x) ← distribute and simplify both sides
10 - 20x - 30x = - 6 + 40 - 60x
10 - 50x = 34 - 60x ( add 60x to both sides )
10 + 10x = 34 ( subtract 10 from both sides )
10x = 24 ( divide both sides by 10 )
x = =
