Answer:
- equation: (7x-4) +19 +(10x+3) = 52
- x = 2
- red: 10
- blue: 19
- yellow: 23
Step-by-step explanation:
The equation is based on the relation that the perimeter is equal to the sum of the side lengths.
P = red + blue + yellow
52 = (7x -4) +(19) +(10x +3)
52 = 17x +18 . . . . . . . . . . . . . . simplify
34 = 17x . . . . . . . . . . . . . subtract 18
2 = x . . . . . . . . . . . . divide by 17
__
red = 7(2) -4 = 10
blue = 19
yellow = 10(2) +3 = 23
40 = n-.40n
40 =n(1-.4)
40 = n(.6
divide by .6 on each side
40/.6 =n
n=66 2/3
Im not sure why you said ur wrong b/c i got the same answer
f(x) = -15+ 7
f(x) = -8
Answer:
24 days
Step-by-step explanation:
To find the answer we need to find the LCM
first, find the prime factorization of 6 and 8
6=2*3
8=2^3
8*3=24
So she'll swim and jog on the same day in 24 days
Answer:
£116.67
Step-by-step explanation:
Given;
Nar donated to 4 charities last year. She gave £175 to each of these charities.
The total amount Nar donated is;
Nar = 4 × £175 = £700
For Rana to donate the same amount equally among 6 charity, to determine the amount each charity would receive this year, we need to divide the total amount by the number of charities;
A = £700/6
A = £116.67
