Answer:
The variable titled "the number" is A: 12.
Step-by-step explanation:
The problem is 8 * (x - 6) = 4 * x
Try the first number as x and rewrite the expression.
8 * (12 - 6) = 4 * 12
Following PEMDAS (the Order of Operations), you need to solve the problem inside the parenthesis.
12 - 6 = 6
Rewrite the problem.
8 * 6 = 4 * 12
8 times 6 is 48.
4 times 12 is 48.
The variable in the expression 8 * (x - 6) = 4 * x is 12.
When adding two rational numbers,if a pair of addends has opposite signs ,then the sum will have the sign of the addenda with the greater value among the two.
These examples can better illustrate this concept:
Example 1:
23 + (-3) = 20 (The greater among the two is positive and the result is also positive)
Example 2:
-23 + 3 = -20 (The greater among the two is negative and the result is also negative)
Answer:
585$
Step-by-step explanation:
multiply 55 by 5, then multiply 20 by 8, last multiply 25 by 6 and add each of the totals to one another.
To work out the probability of both errors occuring, simply multiply the probability of the first error by the probability of the second error. Therefore the probability of both errors occurring is 0.2 * 0.3 = 0.06.
20l + 25g -10
replace G with 4 and L with 3
20(3) + 25(4) - 10
60 + 100 - 10
160 - 10
150
he made $150
