Answer:
4
Step-by-step explanation:
5x+10=30
-10 -10
5x=20
(divide both sides by 5)
x=4

<span>Find
the number of fence did Jon and Jim painted
Jon painted 1 – 4
Jim painted 5 – 12
<u>1 – 2 – 3 – 4</u> – <u>5 – 6 – 7 – 8 – 9 – 10 - 11 – 12</u>
- Jon - Jim
They painted a total of 12 fences. Because Jon started on paint in the first up
to 4th fence and Jim started to paint on the 5th going to
the 12th fence. Thus, the total of the fence they painted is still
12.

Answer:
Depending on what the equation is (see below for options) answers are:
or -1,1=x
Step-by-step explanation:
Two possibilities are present:
- The base of an exponential function is the number raised to an exponent of x.
. The base here is 3/8. To find when f(x) = 3, then substitute and solve. 
- If this is a quadratic function then it has a base of x.
. To find when f(x) = 3 then substitute and solve. 
Conversion a mixed number 5 3
8
to a improper fraction: 5 3/8 = 5 3
8
= 5 · 8 + 3
8
= 40 + 3
8
= 43
8
To find new numerator:
a) Multiply the whole number 5 by the denominator 8. Whole number 5 equally 5 * 8
8
= 40
8
b) Add the answer from previous step 40 to the numerator 3. New numerator is 40 + 3 = 43
c) Write previous answer (new numerator 43) over the denominator 8.
Five and three eighths is forty-three eighths
Conversion a mixed number 2 11
12
to a improper fraction: 2 11/12 = 2 11
12
= 2 · 12 + 11
12
= 24 + 11
12
= 35
12
To find new numerator:
a) Multiply the whole number 2 by the denominator 12. Whole number 2 equally 2 * 12
12
= 24
12
b) Add the answer from previous step 24 to the numerator 11. New numerator is 24 + 11 = 35
c) Write previous answer (new numerator 35) over the denominator 12.
Two and eleven twelfths is thirty-five twelfths
Subtract: 43
8
- 35
12
= 43 · 3
8 · 3
- 35 · 2
12 · 2
= 129
24
- 70
24
= 129 - 70
24
= 59
24
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(8, 12) = 24. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 12 = 96. In the next intermediate step the fraction result cannot be further simplified by cancelling.
In words - forty-three eighths minus thirty-five twelfths = fifty-nine twenty-fourths.
