Answer:
x=2
Step-by-step explanation:
-2 + x = -x + 2
Isolate the variable
2x = 4
Simplify
x = 2
Answer:
x = 2
Step-by-step explanation:
you want to move the variables to one side, the numbers to the other side.
x = -x+4
then you move the other x
2x = 4
x = 2
NUMBER 2 AND 3. GIVING BRAINLIEST!!
Answer:
2. a. 11/4
b. 8/6
3. a. 2 1/6
b. 3 2/3
Step-by-step explanation:
So basically for number 2, you need to multiply the whole number and the denominator, then add the numerator.
For number 3, you need to divide the numbers. Like how much does 6 go to 13 or 11 go to 3. The remainder should be the numerator.
Answer:
Step-by-step explanation:
2)a)
[tex]2\frac{3}{4}=\frac{(2*4)+3}{4}=\frac{8+3}{4}=\frac{11}{4}\\\\1\frac{2}{6}=\frac{(1*6)+2}{6}=\frac{6+2}{6}=\frac{8}{6}\\[/tex]
3)
[tex]a) \frac{13}{6}=2\frac{1}{6}\\\\b) \frac{11}{3}=3\frac{2}{3}\\[/tex]

Mrs.Doggendorf drove 45 miles and used 3 3/4 gallons of gas. Her sister Kelly, drove 85 miles and used 8 2/3 gallons of gas. Which driver used fewer gallons of gas per mile
Answer:
Mrs.Doggendorf has fewer gallons per mile
Step-by-step explanation:
Mrs.Doggendorf drove 45 miles and used 3 3/4 gallons of gas
The miles per gallon is
convert 3 3/4 gallons to simple fraction= 15/4 gallons
miles per gallon= 45/15/4
miles per gallon= 45*4/15
miles per gallon= 12 miles per gallon
gallons per mile= 1/12
Kelly, drove 85 miles and used 8 2/3 gallons of gas
convert 8 2/3 gallons to simple fraction= 26/3 gallons
miles per gallon= 85/26/3
miles per gallon= 85*3/26
miles per gallon=9.80 miles per gallon
gallons per mile= 1/9.80
Hence Mrs.Doggendorf has fewer gallons per mile

Food bill: $36 Tip: 20% Sales tax (on food only) 6%
Answer: To figure out the tip, you need to find 20% of $52.60.
0.2×52.6=10.52
Step-by-step explanation:
Answer:
After eating at your favorite restaurant, you know that the bill before tax is $52.60 and that the sales tax rate is 8%. You decide to leave a 20% tip for the waiter based on the pre-tax amount. How much should you leave for the waiter? How much will the total bill be, including tax and tip? Show work to support your answers.
Solutions
Solution: An exact answer
To figure out the tip, you need to find 20% of $52.60.
0.2×52.6=10.52
You should leave $10.52 for the waiter if you want to leave him exactly 20%.
To figure the tax, you need to find 8% of $52.60.
0.08×52.6=4.208
Next, add them up:
52.6+10.52+4.208=67.328
The total bill, including tax and tip, will be $67.33.
Solution: Estimating an answer
If you are not concerned whether you give the waiter exactly 20%, you can simply estimate the total bill. Tax and tip together are a little less than 30% and the bill is a little more than $50. Since 30% of 50 is 15, the tax and tip together are approximately $15. (Note that the exact calculation is $14.73.)
We can also estimate the total bill as $52 + $15 = $67, which is very close to the exact calculation of $67.33. This kind of estimating is a good way to check the answer to an exact calculation, and more like the way you would probably compute tax and a tip in a real restaurant.
Solution: Exact tax, approximate tip
In a real-world context, restaurant patrons generally estimate the tip, but pay the exact tax based on the calculation of their bill. Therefore, a third solution possibility is for students to estimate the tip portion of the calculations and to find the exact tax when calculating the total bill.
If you wish to estimate the tip, you can round $52.60 to $50. Twenty percent of $50 is $10. So, you would leave a $10 tip.
To figure tax, you need to find 8% of $52.60:
0.08×52.6=4.208.
Next, add the estimated tip, the calculated tax, and the pre-tax bill:
52.60+10+4.208=66.808.
The total bill will be $66.81.

90+52= 142
180-142= 38
Answer:
38
Step-by-step explanation:
all the angles that add up to 180. so you have a 90 degree angle and a 52 degree angle. if you add 90 + 52 you get 142. if you subtract 142 from 180 you end up with 38. so angle R is 38 degrees
