Answer:
37999, 38100, 38300
Step-by-step explanation:
37999
38100
38300
Unit Rate is the Constant Ratio
Perimeter= 2w+2l
l=w+5
Substitute for l
p= 2w+2(w+5)
p= 2w+2w+10
p= 4w+10
58=4w+10
48=4w
12= w
Plug in the width to find length.
l= 12+5
l=17
Final answer: Length-17 cm, Width-12 cm
Answer:
3x + 8
Step-by-step explanation:
x + 5 + 2x + 3 If you put the x's together and the numbers without x's, you will see what is going on much easier.
x + 2x + 5 + 3 = (1 + 2)x + 5 + 3 = 3x + 8
Don't go any further.
Answer:
y = x+15
Step-by-step explanation:
x-values increase by 1, as do y-values. The ratio of increases is Δy/Δx = 1/1 = 1. This is the slope (m) that is needed in the function rule.
The y-value is 15 for an x-value of 0, so we can use 15 as the y-intercept (b) in the function rule.
In slope-intercept form, the function rule is ...
y = mx +b
y = x +15
