Answer:
3x+38
Step-by-step explanation:
1. (10x2 +5x-3)+(7x2 -2x+7) : rewrite problem
2. (20+5x-3)+(14-2x+7) : PEMDAS (10x2=20 and 7x2=14)
3. (5x+17)+(-2x+21) : PEMDAS (20-3=17 and 14+7=21)
4. 3x+38 : Combine like terms
Answer:
You want 40% of 140 gallons to be methane,
so 60% of 140 gallons is water
methane: 0.4(140) = 56 gallons
water: 0.6(140) = 84 gallons

Answer:
a ) hl
Step-by-step explanation:
thats it its rhs actually but hl is still correct
Let x be the number of red fish
3:5 = x:20
3/5 = x/20
(Cross method)
5x = 60
x =12
There are 12 red fish in the fish tank.
Answer:
B. 3 pages are edited every five minutes
D. 6/10 of a page is edited per minute
Step by step:
Three pages are done at an interval of five minutes.
Six tenths of a page is done every minute
0.6 * 5 = 3 per five minutes
The other statements are false.
12/3 = 4, four done every minute, really?
5 pages are edited every three minutes.
This would disprove statement B.
And does not align with the graph.
Hope this helps.
