Write an equation to make the number "24" using all the numbers 5,4,2,2 and +, -, x and ÷.
Answer: See explanation
Step-by-step explanation:
We are given the numbers 5,4,2, and 2 and told to make an equation from it and get a final answer as 24. This will be:
= 5 × 4 + 2 + 2
= 20 + 2 + 2
= 24.
Since we have gotten a final answer of 24, the equation is solved.

How are Ratios,rates and unit rates used to solve problems?
Answer:
hope u understand
Step-by-step explanation:
Unit rates can conveniently be multiplied by any desired number in order to answer questions about differently scaled questions. E.g. If three marbles cost 30 cents, how much will eleven marbles cost?
A unit rate is a ratio such as 30 cents : 3 marbles = 10 cents per (1) marble, after doing the division.
Answer:
ratios, rates, and unit rates can be used to solve how much of something there is compared to another thing. Ex: There are 3 times the amount of apples compared to oranges. How many apples are there if you have 2 oranges? For a ratio, you would make it 3:1. Then substitute the 1 for 2. For a rate, you would make it 3 apples per oranges. Then do the same thing you would do for the ratio. Unit rates work the same way.

1. Solve the following equation. -5p = -75
Answer:
15
Step-by-step explanation:
-5 x 15 = -75
This is according to the rule -a ÷ a = -a and -a x a = -a. Where a negative divided/multiplied by a positive number equals a negative number.
-75 ÷ -5 = 15
-75 ÷ 15 = -5

1760 upper primary pupils took part in a sports meet in 2014. This was decreased of 20% when compared to 2015. The number of the upper primary pupils who took part in 2016 increased by 5% when compared to 2015. How many upper primary pupils took part in the sports meet in 2016?
Answer:
Number of upper primary pupils who took part in the sports meet in 2016 is 1478.
Step-by-step explanation:
Total number of upper primary pupils who took part in the sports meet in 2014 is 1760. It was decreased of 20% compared to 2015.
So that,
20% of 1760 = [tex]\frac{20}{100}[/tex] x 1760
= 0.2 x 1760
= 352
Number of upper primary pupils who took part in the sports meet in 2015 = 1760 - 352
= 1408
Also,
5% of 1408 = [tex]\frac{5}{100}[/tex] x 1408
= 0.05 x 1408
= 70.4
Number of upper primary pupils who took part in the sports meet in 2016 = 1408 + 70.4
= 1478.4
With an increase of 5% compared to 2015, the number of upper primary pupils who took part in the sports meet in 2016 is 1478.

5a+4a=180
a=20
5a=X
X=5×20
=100°
Answer:
100 degrees
Step-by-step explanation:
The opposite angle will always be the same. since the opposite is 5a, then x = 5a. x is 5a, and 9a is 180 degrees so x=180(5/9), which is equal to 100 degrees.

2. What is the slope of the line that passes through the points M(-5,0) and N (6,8)?
Answer:
Hi how are you doing today Jasmine
The slope of the line that passes through the given points M(-5, 0) and N (6, 8) is [tex]\frac{8}{11}[/tex]
Given the following points:
Points on the x-axis = (-5, 6) Points on the y-axis = (0, 8)To calculate the slope of the line that passes through the given points M(-5, 0) and N (6, 8), we would use the following formula;
The slope of a line can be defined as the gradient of a line.
Hence, a slope is typically used to describe both the direction and steepness of an equation of a straight line.
Mathematically, the slope of a line is given by the following formula;
[tex]Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Substituting the given points into the formula, we have;
[tex]Slope. \;m = \frac{8 - 0}{6 - [-5]}\\\\Slope. \;m = \frac{8}{11}\\\\Slope. \;m = \frac{8}{11}[/tex]
