How to Multiply Fractions?To multiply two or more fractions, multiply the denominators of both fractions together, and their numerators together.
1. (-3/4)(7/8)
Multiply the denominators of the fractions together, and also multiply their numerators:

= (-21) / (32)
(-3/4)(7/8) → -21/32
2. (2/3)(-4)(9)
Multiply the denominators of the fractions together, and also multiply their numerators:
= (2 × -4 × 9) / (3)
= -72/3 = -24
(2/3)(-4)(9) → -24
3. (5/16)(-2)(-4)(-4/5)
= (5 × -2 × -4 × -4) / (16 × 5)
= -160/80 = -2
(5/16)(-2)(-4)(-4/5) → -2
4. (2 3/5)(7/9)
= (13/5)(7/9)
= (13 × 7)/(5 × 9) = 91/45

Find the value of m: −3(m − 4) = −6
m = −6
m = −2
m = 2
m = 6
The solution of the equation is m = 6.
How to find the variable of an equation?The variable to find is variable m.
The equation is as follows:
−3(m − 4) = − 6
Hence, let's open the bracket on the left side of the equation
−3(m − 4) = − 6
- 3m + 12 = -6
subtract 12 from both sides of the equation
- 3m + 12 = -6
- 3m + 12 - 12 = -6 - 12
- 3m = - 18
divide both sides of the equation by -3
- 3m / - 3 = - 18 / -3
Therefore,

A mathematical expression known as an algebraic expression includes variables, constants, and algebraic operations (addition, subtraction, etc.). Expressions include terms. Here, y=3x.
What is algebraic expression?The idea behind algebraic expressions is to represent numbers using letters or alphabets rather than giving their exact values. In algebraic basics, we learned how to express an unknown number using letters like x, y, and z. We will refer to these letters as variables from now on. An algebraic expression may have both constants and variables. Any amount that is added to a variable before it is multiplied by another is known as a coefficient.

Mai biked 6\frac{3}{4} miles today, and Noah biked 4\frac{1}{2} miles.
How many times the length of Noah’s bike ride was Mai’s bike ride?
Mai's bike ride was 1.5 times the length of Noah's bike ride
Fractions: A numerical value that designates a portion of a whole is used to represent fractions. A fraction is a component or section taken from a whole, which can be any number, a certain amount, or an object.
Distance travelled by Mai in miles = 6 3/4 miles
Distance of Mai in improper fraction = 27/4
Distance travelled by Noah in miles = 4 1/2
Distance of Noah in improper fraction = 9/2
Length of Noah's bike ride as compared to Mai's bike ride = (27/4)/(9/2)

The two lines at right represent the growing profits of Companies A and B. Homework Help ✎ Sketch this graph on your paper. If Company A started out with more profit than Company B, determine which line represents A and which represents B. Label the lines appropriately. In how many years will both companies have the same profit? Approximately what will that profit be? Which company’s profits are growing more quickly? How can you tell?
Using concepts of linear functions, it is found that:
They will have the same profit after 3 years.This profit will be of $65,000.Due to the higher slope, Company B profit is growing more quickly.What do the slope and the intercept of a linear function represent?The slope-intercept representation of a linear function is:
y = mx + b.
In which:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the x-axis(x = 0).Two linear functions have the same value when they intersect each other, hence, from the graph given at the end of the answer, they intersect around point (3,65), meaning that they will have the same profit after 3 years, and this profit will be of $65,000.
From the Graph, as it assumes higher values as n goes to infinity, company B has the higher slope, hence it's profit is growing more quickly.

Is the picture below a graph for the following inequality? Why or why not?
y<6x+1
Given picture is not a graph of inequality y < 6x + 1
In this question, we have been given a graph.
We need to determine whether the picture is a graph for the inequality y < 6x + 1 or not.
We know that the graph of equation y = 6x + 1 is a straight line and we represent a straight line graph by a solid line.
This graph represents a shaded region below dotted line. This means, this is the graph of inequality.
From this graph we can see that x-intercept of the equation is (2, 0) and y-intercept is (0, - 4)
If we find the x and y-intercept of y = 6x + 1 then it would be,
x - intercept = (-1/6 , 0)
y - intercept = (0, 1)
This means, given picture is not a graph of inequality y < 6x + 1
Therefore, given picture is not a graph of inequality y < 6x + 1

A scuba diver dove from the surface of the ocean to an elevation of −69 9/10
feet at a rate of −21.5 feet per minute. After spending 12.5 minutes at that elevation, the diver ascended to an elevation of −38 9/10
feet. The total time for the dive so far was 19 1/8
minutes. What was the rate of change in the diver's elevation during the ascent? Round your answer to the nearest hundredth.
The rate of change of the divers elevation = 19.274
Given,
The depth to which the Scuba dove = -69 [tex]\frac{9}{10}[/tex] feet
The rate at which he dove = -21.5 feet per min.
The time which he spent at the elevation = 12.5min.
The elevation the diver then ascended to -38 [tex]\frac{9}{10}[/tex] feet
Thee total time for the dove = 19 [tex]\frac{1}{8}[/tex] minutes.
Therefore, the time [tex]t_{d}[/tex] with which the scuba diver descended to -69 [tex]\frac{9}{10}[/tex] feet
is given as follows:
[tex]t_{d} = \frac{Distance}{speed}[/tex] = [tex]= \frac{-69\frac{9}{10} }{-21.5}= \frac{-681}{-21.5}[/tex] = 3.167 minutes
The time [tex]t_{e}[/tex], it took the scuba diver to elevate to -38 [tex]\frac{9}{10}[/tex] feet is given as follows:
[tex]t_{e}[/tex] = 19 [tex]\frac{1}{8}[/tex]minutes - (3.167 + 10.5) minutes = 5.458 minutes
The rate of change of the divers elevation = (Final elevation - Initial elevation)/(Time taken).
∴ The rate of change of the divers elevation
= (-38 [tex]\frac{9}{10}[/tex] - (-69 [tex]\frac{9}{10}[/tex] )) / 5.458 min
=(37.1 - (-68.1))/ 5.458 min

The relationship between two values in an imbalanced algebraic statement is represented by an inequality in mathematics. One of the two variables can be larger than, more than or equal to, smaller than, or equal to another value by using a sign of inequality. Make use of the following steps to solve an inequality: Step 1: Remove fractions by multiplying all terms by the fractions' lowest common denominator. Step 2 Combine like terms on both sides of the inequality to simplify. Step 3 Obtain the unknown on one side and the integers on the other by adding or subtracting quantities.

Step-by-step explanation:
given 2 similar objects with ratio of sides a : b , then

If the radius to the inside of the shell is 4 millimeters and the radius to the outside of the shell is 4.3 millimeters. the volume of the shell is 19π mm³.
Volume of the shellv = 4 / 3πr³
dv =4 / 3π (3r²) dr
Where:
r= radius = 4 cm
dr = 4.3 -4 = 0.3
Hence,
dv = 4 / 3π (16) 3/10
dv =4 / 3π(16) 0.3
dv = 19.2π mm³
dv = 19π mm³ (Approximately)

pounds of bacon for every 2 tomatoes used and 5 tomatoes for every full head of lettuce used.
If Omar is making enough BLT sandwiches to use 2 full heads of lettuce, then he is going to use pounds of bacon and will make a total of BLT sandwiches.
Reset Next
by using multiplication, we get that 28 BLT sandwiches can be made by Omar.
We are given that:
For every full head of lettuce used,
Number of tomatoes used = 5
Now, we will use multiplication.
2 full heads of lettuce used = 5 × 2 = 10 tomatoes used
Now, we also have:
2 tomatoes used = 1 1/20 pounds of bacon used.
= 21/20 pounds of bacon used.
1 tomato = (21 / 20) × (1 / 2) = 21 / 40 pounds bacon
10 tomatoes = (21 / 40) × 10 = 21 / 4 pounds bacon
Also,
3 / 4 pounds of bacon = 4 sandwiches
1 pound of bacon = 16 / 3 sandwiches.
21 / 4 pounds of bacon = (16 / 3) × (21 / 4) = 28 sandwiches
Therefore, by using multiplication, we get that 28 BLT sandwiches can be made by Omar.

We want to get rid of the 6 first
It is a divide so we want to do the inverse, which is multiply both sides by 6
1.4 + x * 6/ *6 = 2.4 * 6
Combine (the 6/6 becomes 1)
1.4 + x = 14.4
