20*.4= 8
(20 as the original price, .4 is 40% as a decimal)
20+8
(eight being 40% of 20)
$28 is the new price.
Children ticket price=£9
Adult ticket price=£17
Let adult=A
Children=C
So, 2A+3C=61 (equation 1)
3A+5C=96(equation 2)
Multiply equation 1 by 3 and equation 2 by 2
Solve equations and get the answer.
14.1% of 278 is 39.2. So 39.2 megabytes have been downloaded.
Answer:
x=-6
Step-by-step explanation:
Use Substitution
so 5-2x=-4x-7
I'ma move that -4x to the other side by making it a positive
5+2x=-7
than I'ma move that 5 to the other side by making it a negative
2x=-12
to isolate the x you dived by both sides by the 2
x=-6
I doubled checked and it's -6
