Students need at least 75 hours of volunteer service to meet their graduation requirement. Samir has already completed 48 hours. Write and solve an inequality to determine how many more hours he needs to complete.

Answers

Answer 1

Answer: R is the amount of hours remaining to complete the requirement

R + 48 ≥ 75

Subtract 48 from both sides of the equation:

R ≥ 27

He has to complete an amount of hours greater than or equal to 27

Answer 2

Answer: a variable, so I will use the variable X then your hours completed which is 48, so it looks like (X + 48) now we have to compare it to how many hours he needs to do. Because it says at least we use the sign , Now the equation is X + 48 75.
X + 48 75

Find the radius of a circle if a central angle of π intercepts an arc of 32 inches. Round to the nearest tenth.a. 3.1 in.
b. 10.2 in.
c. 100.5 in.

Answers

Answer: b. 10.2 in.

Step-by-step explanation:

We know that the formula to calculate the length of arc is given by :-

$l=\theta* r$

Given : The central angle : $\theta=\pi$

The length of arc : $l=32\text{ inches}$

$\Rightarrow32=\pi* r\n\n\Rightarrow\ r=(32)/(\pi)=10.18591635\approx10.2\text{inches}$

Hence, the radius of the circle =10.2 inches.

Solve using elimination
Multiply the first equation by 2 and the second by 5 so you can figure out x
10x-6y=-18
10x-25y=20
Subtract the two equations
19y=-28
y=-2
Plug y into the equation and you get x=-3
(-3, -2)
2. C Just model the equation
3. B Again, it's all about turning the word problem into equations
4. D. Use substitution and plug the x into the first equation.
5.
Multiply the whole first equation by 2.
You can see that because 4*2=8
8x+10y=16
Hope this helps.

coinciedent equations are the same equations but indifferent forms
example
2x+3y=2 is coincident with 4x+6=4 (multilied by 2)

so we have
4x+5y=8
next one was have
8x
we see that 4 times 2=8 so we just double the numbers
5 times 2=10
8 times 2=16
answer is 8x+10y=16
missing numbers are 10 and 16

subsitution meathod
absicalyy since you have x=y+2, then subsitue y+2 for x in the equaiton x+y=6 so
(y+2)+y=6

child tikcet is 2 dollars so number of children times cost per child=cost
c times 2=cost=2c

adult tickets are same but differenc cost
6 times a=6a

so number of adults+number of kids=total number of people
c+a=38

cost of adults+cost of kids=total cost
2c+6a=148

the equations are
c+a=38 and 2c+6a=148
the answer is A

the solution is in the form (x,y)
so solv for x and y
5x-3y=-9
2x-5y=4
multily the first equation by -2 and the second equaiton by 5

-10x+6y=18
10x-25y=20
add them together

-10x+6y=18
10x-25y=20 +
0x-19y=38
-19y=38
divide both sides by -19
y=-2
subsitute
5x-3y=-9
5x-3(-2)=-9
5x+6=-9
subtract 6 from both sides
5x=-15
dvide by 5
x=-3

x=-3
y=-2
solution is

Becka says that when she simplifies the expressions below the value is 6 less than her age

Answers

because you don't have a value for Becka's age it would be a variable which is a letter so let's just say X

less than is a turn around word so it won't be 6 - X
your answer would be X-6
