y = 2x - 3
Step-by-step explanation:
Answer:
The answer is C
Step-by-step explanation:
Both f(x) and g(x) have a domain of [0,infinite). and a range of [0, infinite).
If the weight of the little brother is x, then the weight of Charles is x + 9
The equation that can be used to determine what each one weighs is:
x + (x + 9) = 99.
Let us now solve it.
x + x +9 = 99
2x + 9 = 99
2x = 99 - 9
2x = 90
x = 90/2
x = 45
Little brother's weight is 45 kg.
Charles' weight will be 45 + 9 = 54 kg
Adding these two weights will give 99kg
Answer:
n = 5
Step-by-step explanation:
180(n − 2) = s
180(n − 2) = 540
180n - 360 = 540
180n - 360 + 360 = 540 + 360
180n = 900
(1/180) 180n = 900 (1/180)
n = 5
Answer:
10 in
Step-by-step explanation:
Let x be the width of the mat width showing around the picture. Since the sheet is 20 in wide by 15 in high, and the perimeter of the mat is 110 in. We have the following equation:
2*(20 + x + 15 + x) = 110
35 + 2x = 55
2x = 20
x = 20/2 = 10 in
