First step: Isolate the term that has x. To do that, subtract 2y from both sides.
Now divide both sides by 3.
Answer:
Step-by-step explanation:
Days with t are: Tuesday, Thursday and Saturday.
In the period of time given there are 20 T days (20 x 3 = 60 oranges)
In the period of time given there are ? no T days (27 x 2 = 54 oranges)
60 + 54 = 114 Oranges eaten over the school holidays
Hello from MrBillDoesMath!
Answer: b = 4, h = 13
Discussion:
For a triangle with base b" and height "h, the area formula is
A= (1/2)bh.
In our case A = 26, h = 5b-7, so
26 = (1/2) b (5b-7). Multiply both sides by 2:
26*2 = b(5b-7) =>
52 = b(5b-7) =>
52 = 5b^2 - 7b => (subtract 52 from both sides)
5b^2 - 7b - 52 = 0. This factors as follows:
(b - 4) (5 b + 13) = 0 (use quadratic formula to find this)
so b = 4 and h = 5b -7 = 5*4 - 7 = 13
Thank you,

Answer:
4.4471336 * 10^2.
Step-by-step explanation:
(6.253•10^-2)(7.112x10^3)
= 6.253*7.112 * 10^-2*10^3
= 44.471336 * 10^1
= 4.4471336 * 10^2.
