Answer:
x=30
Step-by-step explanation:
(30+x)+30+9x=360
We move all terms to the left:
(30+x)+30+9x-(360)=0
We add all the numbers together, and all the variables
(x+30)+9x+30-360=0
We add all the numbers together, and all the variables
9x+(x+30)-330=0
We get rid of parentheses
9x+x+30-330=0
We add all the numbers together, and all the variables
10x-300=0
We move all terms containing x to the left, all other terms to the right
10x=300
x=300/10
x=30
Answer:
Option (C)
Step-by-step explanation:
Let the relation between amount of money (m) and Time (t) is represented by the equation,
m = ct + b
Where c = Investment per week
b = Ben already had the amount before investment
From the question,
c = $5 per week
b = $100
Therefore, equation will be,
m = 5t + 100
If duration of the investment 't' = 8 weeks
Amount in the account after 8 weeks,
m = 5(8) + 100
m = $140
Option (C) is the correct option.
Answer:
D (i hope)
Step-by-step explanation:
When you minus the highest to the lowest it is added by 10 so
160-140= 20
140-110=30
110-70= 40
70-20= 50
I had added 10 to 160 and got 170
Answer:
see below
Step-by-step explanation:
This is not a linear function because it does not pass the vertical line test
A vertical line is not a function, it is a relation.
Given, Sylvie needs $110 for a concert ticket.
Sylvie has $16.
Her hourly earnings = $h
Sylvie is working 10 hours at her job.
She is getting in 1 hour = $h
So, 10 hours she will get = $ = $
So the total amount she has now = $16 + $(10h) = $()
So we can write the equation as,
110=16+10h
We can move 16 to the left side also. 16 is added to the right side. We can move it by using reverse operation of addition. Reverse operation of addition is subtraction. So we will subtract 16 from both sides. Subtracting 16 we will get,
110-16=16+10h-16
110-16=10h
We have got the required answer.
To find Sylvie's hourly income the correct options are option A and option D.
