This kinda sounds like system of equations to me. Let's use some variables. 'x' would be the fee for the regular selections. 'y' would be the fee for the discounted selections. Let's start making our equations :O. Here's Pat's order: 2x+4y=119.80. Here's Carlos' order: 3x+5y=160.75. Now, there are different ways of solving these variables such as using substitution, but I will use linear combinations method/elimination method to solve this. I will try to make one variable value the opposite of the other equation's variable. I can get 6x+10y=321.50 and -6x-12y=-359.4. I can eliminate the x now and only have variable y. -2y=-37.9. Dividing both sides gets me y=18.95. I can substitute the y value for y in any equation. so 2x+4(18.95)=119.80. 2x+75.8=119.80. 2x=44. 2x/2=44/2. x=22. Therefore, the fee for regular selections is 22 while the fee for discounted selections is 18.95. Hope you enjoyed this session of learning :3
61.
40 ==> 100 %
x ==> 15 %
15*40/100 = 6.
Therefore, merely 6 students received C grades.
62.
23 500 ==> 100%
x ==> 42 %
42*23500/100 = 9870
Therefore 9870 people in the town are over 45 years of age.
You continue wth this method and you'll find for the 63, 64, 65.
In maths, you have to understand what you're doing dude ^^.
Whatever the answer for 64 and 65 are
64.
21.50*20/100 = 4.3
65.
250 ==> 100 %
45 ==> x %
x = 45*100/250 = 18 %
i will let you do the 63 alone, give me what you have found in the comments, i'll verify your answer.
Hope this helps !

Answer:
g(6)= -13
Step-by-step explanation:
g(6)=−1−77
Step 1: Simplify both sides of the equation.
g(6)=−1−77
6g=−1+−77
6g=(−1+−77) (Combine Like Terms)
6g=−78
6g=−78
Step 2: Divide both sides by 6.
6g/6 = −78/6
g=−13
So you would make this equation
2x+3x=60
5x=60
x=12
smaller=24
larger=36
Answer:
x = 2
Step-by-step explanation:
I used the process of substitution to do this.
<em>1. put </em><em>both</em><em> equations into </em><em>slope-intercept form:</em>
y = 3x - 5
y = -2x + 5
<em>2. since they </em><em>both equal y</em><em>, they must </em><em>equal each other:</em>
3x - 5 = -2x + 5
<em>3. </em><em>simplify:</em>
2 = x
