Answer:
I won't be able to solve the entire question but I will give you the formula and show you how to find the answer
4) 1.65x + 1.36y = 118.17 (i)
x + y = 79. (ii)
From the (i) equation you get
1.65x = 118.17 - 1.36y
x = (118.17 - 1.36y)/1.65 (iii)
Substituting the value of (iii) in (ii)
(118.17-1.36y)/1.65 + y = 79
When you solve it you will get the answer
After that find the value of x and y and multiply them by 1.65 and 1.36 respectively.
Then find their difference and see which class sold more and by how much.
Hope this helps you!
The answer is 12 x 2 + 7 x 2 = 24+12= 38.
Explanation: To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.
Answer:
James' score: 28
Chris' score: 7
Step-by-step explanation:
Call x James' score and y Chris'
James scored 4 times as many points as Chris
x = 4y
The 2 players scored a total of 35 points
x + y = 35
Replace x in the second equation with 4y (they are equal)
4y + y = 35 ===> 5y = 35 ===> y = 35/5 ===> y = 7
replace now this value in the first equation
x = 4y = 4*7 = 28
So James' score: 28, Chris' score: 7
4) 41/4, 14/4, 55/6, 34/7,60/8, 47/9, 27/6, 48/5, 31/3, 50/7,
5a) 132/6= 22
b) 146/9= 16.22
c) 147/2= 73.5
d) 107/4= 26.75
e) 156/8 = 19.5
f) 148/9 = 16.44
