Answer:
Ans = 42
Step-by-step explanation:
just substitute the variables with their respective value
x² + 2y ÷ w + 3z
= 5² + 2(8) ÷ 2 + 3(3)
= 25 + 16 ÷ 2 + 9 <bear in mind, have to do multiplication/division before addition/substraction>
= 25 + 8 + 9
= 42
(0,-5), (1,-4), (2, -3), (3, -2), (4, -1), (5,0) is this a relation

George is correct they said that the ratio of pools open on weekends to the total number of pools is 6:16.
What are ratios and proportions?A ratio is an ordered pair of numbers a and b, denoted by the symbol a / b, where b does not equal zero. A proportion is an equation that sets two ratios equal to each other. For example, if there is one boy and three girls, the ratio could be written as 1: 3. (for every one boy there are 3 girls) One-quarter are boys and three-quarters are girls.
Given that In a city, there are 16 swimming pools. On weekends, 6 of the pools are open.
George says the ratio of pools open on weekends to the total number of pools is 6:16.

Solve for m.
m – 7/8 = 5
Write your answer as a fraction or as a whole or mixed number.
m = ____
Answer:
5 7/8
Step-by-step explanation:
Do the inverse operation.
5 + 7/8 = 5 7/8
Or, do this instead!
Add 7/8 to both sides of the equation. On the side before the equal sign, -78 and +78 cancel out, leaving m all by itself. Bring down the equals sign and we have m = 5 7/8!

Alex knows 18% of the students surveyed at his school are dropped off by car while 22% walk or ride bikes and the rest ride the bus Which table could represent this information ?
Answer:
The second option.
Step-by-step explanation:
First, the percentages in the "walk" and "ride bike" sections will have to add to 22% as the information says. All of them do except the third option, so that's ruled out.
Next, the rest of the categories have to finish to complete 100%- so they need to add to 78%. Only one of them do, the second with 18% car and 60% bus!
