-1 / 7 = x
You need to combine the 2x and 5x then devise the 7x from -1
To determine the rate of a number do the following steps:
Multiply the number by the percent (e.g. 87 * 68 = 5916)
Divide the answer by 100 (Move decimal point two places to the left) (e.g. 5916/100 = 59.16)
Round to the desired precision (e.g. 59.16 rounded to the nearest whole number = 59)
Answer:
w=10
Step-by-step explanation:
1. Divide 4 on both sides to cancel out the 4 on the right side since it is an equation so it has to remain “equal”/ balanced.
2. You get 7=w-3.
3. Add 3 on both sides.
4.You get w=10.

Answer:
Definitions:
The third quartile, denoted by Q3 , is the median of the upper half of the data set. This means that about 75% of the numbers in the data set lie below Q3 and about 25% lie above Q3;
The upper half of a data set is the set of all values that are to the right of the median value when the data has been put into increasing order;
First, we verify data in increasing order:
21, 24, 25, 28, 29, 35, 37, 38, 42 ( okay);
The median is 29;
Therefore, the upper half of the data is {35, 37, 39, 42};
Q3 = ( 37 + 39 ) / 2 = 76 / 2 = 38;
