Answer:
y= 34x- 2 +5 (C)
Step-by-step explanation:
The equation: y = 27x-54 +5
We are to determine an equivalent equation of the form y=avx -h+k from the options given.
From the above, av = two digit coefficient of x. Hence av is constant.
h and k are also constant.
Let's check out the option to find the equation that is in the form y=avx-h+k
a) y=-273x + 2+5
In this equation, the coefficient of x is a 3-digit number. The option is wrong.
b) y=-3x+2 +5
In this equation, the coefficient of x is a 1-digit number. The option is wrong.
c) y=34x -2 +5
In this equation, the coefficient of x is a 2-digit number.
av = 34, h= 2 and k = 5
This equation is in the form of y=avx -h+k
The option is correct.
d) y=273/x-2 +5
This equation is not in the form of y=avx -h+k
The option is wrong.
Inequality: 21d+25≤115
Jim can rent a car for maximum 4 days, therefore, he is not correct in his calculations.
Step-by-step explanation:
Given,
Per day rent = $21.00
Per mile rent = $0.10
Miles to be driven by Jim = 250
Cost of 250 miles = 250*0.10 = $25
Amount Jim can spend = $115.00
Let,
d represent the number of days.
Per day rent*number of days + cost of 250 miles ≤ Total amount to spend
21d+25≤115
Subtracting 25 from both sides
Dividing both sides by 21
Jim can rent a car for maximum 4 days, therefore, he is not correct in his calculations.

Answer:
570 adults and 215 children
Step-by-step explanation:
did this assignment and got it right
5a + 2c = 3280 where a is adults and c is children
subtraction eliminates c, find a
3a + 0 = 1710
a = 1710/3
a = 570 adult and then you have to subtract 785-570= 215 children
<span>The correct answer is 12/17m+30/17 yellow ribbons.
Explanation:
Setting up a proportion to represent the ratio of red to yellow, we have
r/y = 17/6.
Cross multiply:
6r=17y.
To isolate y, cancel 17 by dividing:
6r/17 = y, or (6/17)r=y.
Substituting 2m+5 for r, we have
(6/17)(2m+5)=y.
Use the distributive property:
(6/17)*2m+(6/17)*5=y
(12/17)m+30/17=y.</span>
