Answer: Angle z=75°.

Step-by-step explanation: You have a supplementary angle meaning the angles add up to 180°. So you would just subtract the number you are given (105°) from 180° and get 75°.

A moving company charges $40 plus $0.25 per mile to rent a van. Another company charges $25 plus $0.35 per mile to rent the same

Bond [772]

<h3>Answer:</h3>

c. 150 miles

<h3>Step-by-step explanation:</h3>

You want to find the number of miles (m) that make the charges equal.

... 40 +0.25m = 25 + 0.35m

... 15 = 0.10 m . . . . . . add -25-0.25m

... 150 = m . . . . . . . . . divide by the coefficient of m

For 150 miles, the rental cost will be the same for both companies.

Last time, one out of every 4 students in our class was absent. This time, after Jen came back, only one out of every 5 students

VMariaS [17]

Answer: There are 20 students and 4 students are not here today.

Step-by-step explanation:

If the number of students = 4

Let the number of students be 'x'.

Fraction of students absent = $\dfrac{x}{4}$

If the number of students = 5

Fraction of students absent = $\dfrac{x}{5}$

And Jen came back,

So, the fraction of student absent is also written as

$\dfrac{x}{4}-1$

According to question, it becomes,

$\dfrac{x}{5}=\dfrac{x}{4}-1\\\\\dfrac{x}{5}=\dfrac{x-4}{4}\\\\4x=5(x-4)\\\\4x=5x-20\\\\4x-5x=-20\\\\-x=-20\\\\x=20$

Hence, there are 20 students in our school.

And number of students are not here today is $\dfrac{20}{5}=4$

Which equation has only 1 solution? A. c+2=c+2 B. c= -c+2 C. c+2=c-2 D. c-c=2 Please explain.

zhannawk [14.2K]

Answer:

B. c= -c+2

Step-by-step explanation:

A. ...................

c+2=c+2
c-c= 2-2
0=0

It has infinitely many solutions as the equation is correct for any value of c.

B. ...................

c= -c+2
c+c= 2
2c = 2
c = 2/2
c= 1

It has one solution only

C. ...................

c+2=c-2
c-c= -2 - 2
0 = -4

It has no solution as this equation is incorrect

D. ...................

c-c=2
0 = 2

It has no solution as this equation is incorrect
