The answers are x=4 and y=323/2
1) 40/2x-3=8
Multiply both sides by 2x-3 to get rid of fraction
40= 8(2x-3)
Distribute 8
40= 16x-24
Add 24 to both sides
64=16x
Divide by 16
4=x
2) 2y-3/40=8
Multiply both sides by 40 to red rod of fraction
2y-3=320
Add 3 to both sides
2y= 323
Divide by 2
Y=323/2
Now just describe the differences in solving them
FYI / means fraction, right after the slash is bottom of fraction
The answer for number 3 is 96.7 if you want the work shown I would recommend you to download the app Socratic and for number six you multiply.75x14 then also multiply.35x7 then add add up the answers which will be 12.95 then you subtract that from 15 the answer is $2.05
Independent: cell phone plan
dependent: monthly cost
constant: per month/per minute (money)
Length=3/4 mi and width=1/2 mile so
L:W=(3/4):(1/2) by convention we will express this ratio with integers...multiplying both fractions by 4 we get:
L:W=3:2
Answer:
<em>1) 6%</em>
<em>2) $1,689.35</em>
Step-by-step explanation:
1) Given the following
Sales tax = $64.80
Price of the computer = $1080
Required
rate of sales tax
Using the expression
x% of 1080 = 64.80
x/100 * 1080 = 64.80
10.80x = 64.80
x = 64.80/10.80
x = 6%
<em>Hence the rate of sales tax is 6%</em>
<em></em>
2) Given the following
Price of the car = $25,990
Tax rate = 6.5%
Sales tax charged = 6.5% of $25,990
Sales tax charged = 6.5/100 * 25,990
Sales tax charged = 6.5 * 259.9
Sales tax charged = $1,689.35
<em>hence the sales tax being charged is $1,689.35</em>
