Answer:
Step-by-step explanation:
Assumed the question is how many pages are in each chapter.
<u>Let it be x:</u>
- 6x + 8 = 194
- 6x = 186
- x = 186/6
- x = 31
Answer:
8,10 ,12
Step-by-step explanation:
x
x+2
x+4
5x-18 =x+2 + x+4
5x-18=2x+6
3x=24
x=8
8*5=40 40-18= 22
10+12 = 22
You need to isolate x, which means you need to get it alone. 16x and 11x are like terms because they both have an x, do subtract them. 16-11=5. So 15 = 5x
Then to turn 5x into x, divide by five. This is because 5/5 is 1, and 1x is x. Divide both sides, so
X = 3
Answer:
option (A) 62 miles
Step-by-step explanation:
Data provided in the question:
Ratio on the left = 434 miles : 14 gallons
ratio on the right = ?? : 2 gallons
Now,
The ratio on the both sides are equal
let the unknown value in the ratio be 'x'
Now, the ratio a : b can also be represented as 
therefore,
434 miles : 14 gallons = x : 2 gallons
or
⇒
=
or
⇒ x =
or
⇒ x = 62 miles
Hence,
the correct answer is option (A) 62 miles
