Multiply and do math
Suppose y varies directly as x, and y = 21 when x = 3. Find x when y = 42.
Answer:
x = 24
Step-by-step explanation:
y₂ - y₁
42 - 21 = 21
x + 21
3 + 21 = 24
So when y increases by 21, so does x.
x = 24

The product of two positive numbers is always greater than either number
The product of two positive numbers is always greater than either number the statement is false.
What are numbers?A numeral system is a way of writing numbers; it's a way of mathematically notating a collection of numbers by utilizing a consistent set of digits or other symbols. In several numeral systems, the same set of symbols may represent various numbers.
Given that the product of two positive numbers is always greater than either number.
To understand this let's take an example take two numbers and multiply them.
2 x 5 = 10
Then take 2 and 0.5 and multiply them.
2 x 0.5 = 1
Here the result of the product is 1 which is less than 2. Therefore, if the product of two positive numbers is always greater than either number the statement is false.

Answer: (1) -3/4 (2) 7 (3) y = (-3/4)x + 7 (4) 1/2
Step-by-step explanation:
1) COUNT the number of spaces from one point to the other point.
from (0, 7) to (4, 4) is: down 3 and right 4 → m = -3/4
2) the y-intercept is where the line crosses the y-axis (when x = 0).
The line crosses the y-axis at (0, 7) → b = 7
3) Slope-Intercept form is y = mx + b
m = -3/4 and b = 7 → y = (-3/4)x + 7
4) COUNT the number of spaces from one point to the other point.
from (-2, -4) to (2, -2) is: up 2 and right 4 → m = 2/4 = 1/2 when simplified
What integers are closest to the square root of 54 on the number line?
Answer:
sqrt(54) is between 7 and 8
Step-by-step explanation:
Lets look at integers that are squared
1^2 = 1
2^2 = 2
3^2 = 9
4^2 = 16
5^2= 25
6^2 = 36
7^2 = 49
6^2 =64
54- 49 = 5 and 64 - 54 = 10
So 54 is closer to 49
so sqrt(54) is closer to the sqrt(49) = 7
sqrt(54) is between 7 and 8

The value of x for the given triangle will be 111°.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.
The sum of all angles inside a triangle is 180°
So,
47° + x° + 22° = 180°
x = 180° - 69° = 111°
Hence "The value of x for the given triangle will be 111°".

in a salad with vegetables containing 50 calories dressing is added at 100 calories per ounce. The total number of calories can be represented by the equation f(x) = 100x +50. What is the reasonable range for the situation?
Answer:
Step-by-step explanation:
To get the reasonable range of the situation, we will find the minimum value and maximum value of the calories that can be dressed.
The minimum occur at when x = 0
f(0) = 100(0) +50.
f(0) = 50
Hence the minimum value of the calorie is 50.
The maximum value occur at f'(x)
f'(x) = 100
Hence the maximum value of the calorie is 100
Hence, the reasonable range for the situation is 50 ≤ x ≤ 100

Justin is buying a cell phone that had a wholesale price of
$495. The cell phone was marked up 25%.
What is the selling price of the cell phone?
Answer:
$371.25
Step-by-step explanation:
If you want to take away 25%, you would need to find out how much 75% of the current price is. IF you think about it, 75% of the $495 is 25% of 100% of it taken away.
So
0.75 x 495 = 371.25

Why does the government charge high taxes on gasoline?
Answer:
Every time you top off your vehicle at the pump, you're paying federal and state gas taxes that are included in the price of every gallon of gasoline. The federal tax, at 18.4 cents per gallon, is meant to help the federal government pay to build and fix things like highways and bridges.
Step-by-step explanation:
Mark me brainliest
Answer: These taxes are meant to do two things — raise money to pay for infrastructure and reflect some of the environmental costs of driving. Unlike most taxes, gas taxes are charged as a flat charge per liter, rather than as a percentage of the pump price.
