Explain how to model the multiplication of 3 and ‒4 on a number line
Answers
First, start at zero. Now, because we are multiplying -4 by 3, we will jump over by 4 to the left ; 3 times on the number line. We should reach -12, and if we check our work, 3 x -4 = -12.
Final answer:
To model the multiplication of 3 and -4 on a number line, start at zero and make three moves to the left by 4 units, ending up at -12. This demonstrates the rule that multiplying numbers with opposite signs results in a negative product.
Explanation:
To model the multiplication of 3 and -4 on a number line, you can follow these steps:
Start at zero on the number line.
Since you are multipling a positive number by a negative number, you will move in the negative direction (to the left).
Make three moves (corresponding to multiplying by 3), each 4 units to the left. This represents adding -4 three times.
Where you end up on the number line is the product of 3 and -4, which is -12.
This method of multiplication on a number line illustrates the rule that when two numbers multiplied have opposite signs, the answer has a negative sign, such as in the example ( -4) x 3 = -12.

Step-by-step explanation:
We are given that an expression
[tex]\frac{5}{6}-\frac{11}{6}[/tex]
We have to find the correct value of given expression on the number line.
[tex]\frac{11}{6}=1\frac{5}{6}[/tex]
[tex]\frac{5}{6}-\frac{11}{6}[/tex]
[tex]\frac{5-11}{6}=\frac{-6}{6}[/tex]
[tex]\frac{5}{6}-\frac{11}{6}=-1[/tex]
[tex]\frac{5}{6}+(-1\frac{5}{6})[/tex]
When an integer positive and other integer negative and add them .If negative integer is greater and positive integer is small then we go from left to right.
We go [tex]\frac{5}{6}[/tex] step from [tex]-1\frac{5}{6}[/tex]towards right then we reach at [tex]{-1}[/tex].
Hence, -1 is the correct value of given expression.

Multiplying a number by 4/5 then dividing by 2/5 is the same as multiplying by what number?
Answers
number * 4/5 * 5/2 = number * 20/10 = number * 2
2
Therefore, it would be:
x * 4/5 / 2/5
Division is basically multiplying by the second number flipped, like so:
x * 4/5 * 5/2
Then you could just multiply, saying
x * 20/10
or x * 2
So it's the same as multiplying by 2.

A school library has 260 DVDs in its collection. Given that 45% of the DVDs are about science and 40% or about history how many of the DVDs are about other subjects?
Answers
39 DVDs are about other subjects.
To determine the number of DVDs about other subjects in the school library, we must first calculate the number of DVDs dedicated to science and history. We start by finding 45% of 260 DVDs for science and 40% of 260 DVDs for history.
Science DVDs: 45% of 260 = 0.45 * 260 = 117
History DVDs: 40% of 260 = 0.40 * 260 = 104
Adding the numbers of science and history DVDs gives us the total number of DVDs not about other subjects:
117 (Science) + 104 (History) = 221
To find the number about other subjects, we subtract the total number of science and history DVDs from the total collection:
260 (Total) - 221 (Science and History) = 39 DVDs about other subjects.

Answer:

Step-by-step explanation:
Showing the time for 1 to 5 meetings means we would go from 43(1) = 43 to 43(5) = 215 for the y-axis (time in minutes).
We are counting by 10s. The two closest tens to 215 are 210 and 220. However, in order to show 215 on the graph, we must go up to 220.

For $360, a rock-climbing gym offers yearly membership where members can climb as many days as they want and pay $4 per day for equipment rental. Nonmembers pay $10 per day to use the gym and $6 per day for equipment rental. Write an equation to find the number of visits after which the total cost for a member and the total cost for a nonmember are the same. Then solve the equation.
Answers
$4x+$360=$10x+$6x
Combine like terms.
$4x+$360=$16x
Subtract $4x on both sides to balance out the equation.
$12x=$360
Divide by $12.00 on each side.
x=30 visits
To check your work, plug in what x equals or 30 in the original equation. If you come up with a true statement, then you know your answer has to be correct.
4x+360=16x
4(30)+360=16(30)
120+360=480
480=480
Because this is a true statement, you can be certain that the total number of visits when the cost of a member and a nonmember will be the same is 30 visits. Hope I helped! Brainliest too please.

Answer:
[tex]1\frac{1}{4}[/tex]gallon/hour
Step-by-step explanation:
After [tex]2\frac{1}{4}[/tex] hour a chainsaw has used [tex]2\frac{13}{16}[/tex] gallons of fuel.
[tex]2\frac{1}{4}[/tex] hours = [tex]\frac{9}{4}[/tex] hours
[tex]2\frac{13}{16}[/tex] gallons = [tex]\frac{45}{16}[/tex] = 2.8125 gallons
The chainsaw used fuel after [tex]\frac{9}{4}[/tex] hours = [tex]\frac{45}{16}[/tex] gallons
The chainsaw used fuel in 1 hour = [tex]\frac{\frac{45}{16}}{\frac{9}{4}}[/tex]
= [tex]\frac{45}{16}[/tex] ÷ [tex]\frac{9}{4}[/tex]
= [tex]\frac{45}{16}[/tex] × [tex]\frac{4}{9}[/tex]
= [tex]\frac{180}{144}[/tex]
= [tex]\frac{90}{72}[/tex]
= [tex]\frac{30}{24}[/tex]
= [tex]\frac{15}{12}[/tex]

Answers
The bar of chocolate should be broken [tex]\boxed{\bf 71\text{\bf\ times}}[/tex], so that it is separated into individual squares.
Further explanation:
Given that the bar of chocolate is eight pieces high and nine pieces long.
First break the chocolate horizontally [tex]7\text{ times}[/tex] since, it is eight pieces high.
Now, the broken piece of chocolate is divided into nine single strips of eight pieces each.
Each nine single strip is broken [tex]8\text{ times}[/tex].
Therefore, total number of times the chocolate bar is broken is calculated as follows:
[tex]\begin{aligned}\text{Total number of times}&=7+(8\cdot 8)\\&=7+64\\&=71\end{aliogned}[/tex]
Thus, [tex]71\text{ times}[/tex] the bar of chocolate is broken so that it is separated into individual squares.
Now, break the chocolate vertically [tex]8\text{ times}[/tex] since, it is nine pieces long.
Now, the broken piece of chocolate is divided into nine single strips of nine pieces each.
Each nine single strip is broken [tex]7\text{ times}[/tex].
Therefore, total number of times the chocolate bar is broken is calculated as follows:
[tex]\begin{aligned}\text{Total number of times}&=8+(9\cdot 7)\\&=8+63\\&=71\end{aliogned}[/tex]
Thus, [tex]71\text{ times}[/tex] the bar of chocolate is broken so that it is separated into individual squares.

The correct answer is [tex]g(x)=-x-6[/tex]
EXPLANATION
The mapping for reflection across the x-axis is given by [tex](x,-y)[/tex]
Given [tex]f(x)=x+6[/tex]. We can let [tex]y=x+6[/tex]
we can write the ordered pair [tex](x,y)[/tex] or [tex](x,x+6)[/tex] as the ordered pair of the preimage of [tex]f[/tex].
The image function will have the ordered pair [tex](x,-y)[/tex]
