Answer:
3a+7=5a-3
5a-3a=3+7
2a=10
a=5
Again
6b-5=2b+9
6b-2b=5+9
4b=14
b=14/4=7/2
Step-by-step explanation:
First, you know that Jackson (let call her J) scored 41 more points than L (Leslie). What we don't know is how many points L scored so we can use a variable that will be 'x'.
So the equation will be
J=41+x.
We also know that the total points is 1,189.
To find out what x is we first subtract
1,189-41. We then get 1,148.
We are now left with 2x and 1,148 so we divide
1,148 by 2 and get 574.
574=x so now we can plug that in.
J= 574+41
Jackson scored 615 points and
Leslie scored 574 points
(You can use bar modeling to do solve this problem. An example of bar modeling is shown below.
50-10 = 40. 40 divided by 6 = around 6/7. So about 6/7 weeks
Answer:
Area = 14.8
Step-by-step explanation:
Area = 5/2 + a^2*sqrt(5 + 2 sqrt(5) )
This formula given the side length, calculates the area.
a = 2
Area = 2.5 + 2^2 * sqrt(5 + 2*sqrt(5) )
Area = 2.5 + 4 * sqrt(5 + 2*2.236)
Area = 2.5 + 4* sqrt(5+ 4.4721)
Area = 2.5 + 4*sqrt(9.4721)
Area = 2.5 + 4*3.0776
Area = 2.5 + 12.3107
Area = 14.8107
$0.70 per candy.
$78 divided by 112 gives $0.696, so by rounding off, you get 0.70
