92
The equation we have so far would be: (x-2)÷3=30
plug 92 into x.
(92-2)÷3=30
92-2=90
90÷3=30
9514 1404 393
Answer:
39.375 : 65.625
Step-by-step explanation:
The meaning of "reduce" in this context is unclear. We assume you want to divide the quantity 105 into parts that have a ratio of 3 : 5. Then the smaller part will be 3/(3+5) = 3/8 of the total; the larger part will be 5/8 of the total.
3/8 × 105 = 39 3/8
5/8 × 105 = 65 5/8
The divided quantities are ...
39.375 : 65.625
c. 2310 (1st pic)
circumference of circle = 2πr
44= 2 × 22/7 r
44 × 7 / (2 × 22) = r
7 = r
volume of cylinder = πr^2h
= 22/7 × (7)^2 ×15
= 2310
b. -2/x+3 (2nd pic)
(work attached)
a. 80° (3rd pic)
Total number of degrees is 180
180-(60+40)=80
c. 9 (5th pic)
(27^1/3)^2
3^2
=9
sorry i couldn't solve the 4th pic but I hope this helps!

Answer:
222 miles.
Step-by-step explanation:
<u>Lets create an equation to solve this easier.</u>
<u>Let x represent the miles driven in the truck. </u>
Our equation is 238.51=.98x+20.95
All we have to do now is solve for x.
Subtract 20.95 on both sides.
217.56=.98x
Now divide both sides by .98 to isolate the variable.
222=x
<em>Ivan drove the truck 222 miles.</em>

To calculate the average benefit of hours we must add all the values then divide by the number of values that we have.
<h3>What is the average?</h3>
Average is a term that refers to a value that represents the mean of a group of values. For example, if my friends and I have a race to run from point A to point B and our times are:
- 69 seconds.
- 58 seconds.
- 45 seconds.
- 120 seconds.
- 76 seconds.
The average time of my group of friends would be:
69 + 58 + 45 + 120 + 76 = 368
358 ÷ 73.6 seconds
The average of my group of friends would be 73.6 seconds.
According to the above, to identify the average profit per hour of my neighbors who own their lawns, you must use the same formula to obtain the result.
Note: This question is incomplete because the are some information missing. However I can answer it based on my prior general knowledge.
