you would change the denominators to the least common multiple, in this case, 12. then you would change the fractions to 8/12, 14/12, and 7/12. you would add those, and get 29/12. divide 29 by 12, and get 2. add the rest to get 2 5/12.
Answer:
2.34 * 10^5.
Step-by-step explanation:
234000 = 2.34 * 10^5
- there are 5 digits after the first number so the exponent is 5.

Using the numbers 1 through 9 only once in the boxes, the largest value of x you can get is <u>7</u>.
<h3>What are mathematical operations?</h3>
Mathematical operations refer to the calculation of values using operands and mathematical operators.
Mathematical operations are formed like functions to take zero or more input values (operands) to a well-defined output value.
Some of the mathematical operators perform addition, subtraction, multiplication, division, exponentiation, and modulus operations.
<h3>Data and Calculations:</h3>
Mx + y = z
Let m = 1
x = 7
y = 2
1 x 7 + 2 = 9
7 + 2 = 9
9 = 9
Thus, using the numbers 1 through 9 only once in the boxes, the largest value of x you can get is <u>7</u>.

Answer:
5 more men
Step-by-step explanation:
10 men do a job in 6 hours.
To do the job in 2 hours, 1/3 of the time, you need 3 times as many men.
30 men do a job in 2 hours.
To do the job in twice the time, 4 hours, you need half the men.
15 men do a job in 4 hours.
15 men - 10 men = 5 men
You need 5 more men.
