C.
1,250+1,250
D.
1,250+2,500
The solution of the multiplication of the 250 x 15 will be 1250 + 2500. The correct option is D.
What is multiplication?Multiplication is the process of determining the product of two or more numbers in mathematics. A product, or an expression that specifies factors to be multiplied, is what happens when you multiply two numbers in mathematics.
When we multiply a multiplicand by one digit of a multiplier that has more than one digit, the result is known as a partial product.
Given numbers 250 and 15. The multiplication will be done as below:-
250
x 15
--------
1250
2500
--------
3750
Therefore, the solution of the multiplication of the 250 x 15 will be 1250 + 2500. The correct option is D.

Step-by-step explanation:
Melanie has pieces of train track that are 8 inches long that she is connecting together to form a track that her train can travel on. Martin is also trying to construct a track for his train but is using track pieces that are 20 inches long. How long will the shortest track be if the track that Melanie builds ends up being the same length as Martin's track?
Answer:
40 inches long
Step-by-step explanation:
In order to find the shortest possible track that they can both have but still be equal in length, we need to find the least common multiple of their train track pieces. In order to do so, we simply write out the multiplication table of each of their pieces' length until we find a common number, like so
8*1 = 8 20*1 = 20
8*2 = 16 20*2 = 40
8*3 = 24
8*4 = 32
8*5 = 40
Now we have found the first common multiple which is a value of 40 meaning that the shortest train track that they can build with the same length would be a track that is 40 inches long

Answer:
g(x) = (x +1)^2 +3
Step-by-step explanation:
You know that the transformation ...
g(x) = f(x -h) +k
moves the f(x) graph h units to the right and k units up. In this problem, we have h=-1 (1 unit left) and k=3 (3 units up), so the transformation is ...
g(x) = f(x +1) +3
Since f(x) = x^2, the equation for g(x) is ...
g(x) = (x +1)^2 +3

Anna and Hannah have \$80$80dollar sign, 80 each. Their friend offered to invest their money, promising to return a sum rrr times as great as what they invested. Anna was suspicious, so she invested \$20$20dollar sign, 20 only, but Hannah invested her entire \$80$80dollar sign, 80. Fortunately, the friend did indeed return a sum rrr times as great to each.
They decided to make another investment. This time, Hannah invested all of the money returned to her, and Anna invested the money returned to her and the remaining \$60$60dollar sign, 60. Again, they got a sum rrr times as great as what they invested. In the end, Hannah had twice the amount Anna had.

What is an expression?A term is a single mathematical phrase. It might consist of only one variable—a letter—one number—positive or negative—or several variables multiplied but never added or subtracted. A number is placed in front of some nouns that have variables. Coefficients are numbers that come before phrases.
As per the information provided, it is given that,
7(x - 4) - 3(x + 5)
Expanding the brackets and simplifying, we get:
7(x - 4) - 3(x + 5) = 7x - 28 - 3x - 15
7(x - 4) - 3(x + 5) = 4x - 43

Graph line with the equation y=x+6. (Can you explain how to do this overall)
Answer:
First using y = Mx + b with m = slope and b = y intercept so 1/3 = slope and (0,6) is y intercept next plot (0,6) the plot slope from that point with rise/run or from point (0,6) go up +1 point and over +3 and make a point then go up +1 and over +3 or from (0,6) use slope = -1/-3 since they equal the same thing. So from point (0,6) go down -1 and to the left -3. Then draw your line.

Jim was thinking of a number. Jim adds 20 to it, then doubles it and gets an answer of 99.2.
What was the original number?
Answer:
x =29.6
Step-by-step explanation:
Let x be the number
x+20
2(x+20) = 99.2
Divide each side by 2
x+20 = 99.2/2
x+20 = 49.6
Subtract 20
x = 49.6-20
x =29.6

Answer:
C) 145 degrees
Step-by-step explanation:
angles 2 and 5 are same side interior angles, which means they're supplementary. (they add together to make 180)
using that, you can make the following equation:
(x is angle 2 to avoid confusion)
35 + x = 180
subtract 35 from both sides
x = 180 - 35
x = 145
Determine the slope of each line, if any. Identify which of the lines is vertical or horizontal.
1. f(x)=2x-5
2. f(x)= -3x + 7
3. f(x) = x + 6
4. f(x) = 1/4x -8
5. f(x)= 1/4x-1/2
Answers:
slope = 2slope = -3slope = 1slope = 1/4slope = 1/4None of the five lines are horizontal or vertical
===============================================
Explanation:
Something like f(x) = 2x-5 is the same as y = 2x-5. This is because y = f(x).
Compare y = 2x-5 with y = mx+b. We see that m = 2 is the slope in this case.
The other four questions are handled the same way.
A horizontal line occurs when the slope is 0. Since none of the slopes are zero, none of the lines are horizontal.
A vertical line equation is of the form x = k, where k is any real number. The y variable is not involved. It is not possible to write a vertical line equation in the form y = mx+b because the slope m is undefined. So none of the given five equations are vertical lines.
Side note: something like y = x+6 is the same as y = 1x+6

im not sure if im entirely correct, so i apologize in advance
<HDF
<BDG (i think)
<CDE
Step-by-step explanation:
The angles that are adjacent and congruent to ∠ BDC are ∠ HDF , ∠EDH and ∠CDE.
A figure is given in the question.
We have to tell about angles which are congruent to ∠ BDC.
What are the adjacent angles ?
The two angles are said to be adjacent angles when they share the common vertex and side.
As per the definition of adjacent angles ;
we can check for the adjacent angles from the figure.
Here ;
∠ BDC = ∠ HDF.
∠ BDC = ∠ EDH.
∠ BDC = ∠ CDE.
To check , if these are congruent too ; we must know that two angles are congruent when they have the same angle measurement, i.e., they’re equal.
if we compare from the figure ; we found that these angles are also congruent to each other.
Thus , the angles that are adjacent and congruent to ∠ BDC are ∠HDF , ∠EDH and ∠CDE.

A graph titled Motion of Ant is shown. The graph shows time in seconds on the x-axis and the Distance from Hole in centimeters on the y-axis. The scale on the x-axis is shown from 0 to 6 at increments of 1, and the scale on the y-axis is shown from 0 to 12 at increments of 2. The graph has 3 straight lines. The first line is labeled P and joins ordered pairs 0, 0 and 2, 6. The second line is labeled Q and joins ordered pairs 2, 6 and 3, 6.

Aldo the trainer has two solo workout plans that he offers his clients: plan a and plan b. Each client does either one or the other (not both). On friday there 8 were clients who did plan a and 3 who did plan b. On saturday there were 3 clients who did plan a and 5 who did plan b. Aldo trained his friday clients for a total of 7 hours and his saturday clients for a total of 6 hours. How long does each of the workout plans last?
Answer:
x = number of hours to train plan a clients
x = 0.55 hour
y = number of hours to train plan b clients
y = 0.87 hours
Step-by-step explanation:
Friday
Plan a = 8 clients
Plan b = 3 clients
Total hours = 7
Saturday
Plan a = 3 clients
Plan b = 5 clients
Total hours = 6
Let
x = number of hours to train plan a clients
y = number of hours to train plan b clients
8x + 3y = 7 (1)
3x + 5y = 6 (2)
Multiply (1) by 5 and (2) by (3)
40x + 15y = 35 (3)
9x + 15y = 18 (4)
Subtract (4) from (3)
40x - 9x = 35 - 18
31x = 17
Divide both sides by 31
x = 17 / 31
= 0.548 hour
Approximately
x = 0.55 hour
Substitute x = 0.55 hour into (1)
8x + 3y = 7
8(.55) + 3y = 7
4.4 + 3y = 7
3y = 7 - 4.4
3y = 2.6
Divide both sides by 3
y = 2.6 / 3
= 0.867 hours
Approximately
y = 0.87 hours
x = number of hours to train plan a clients
x = 0.55 hour
y = number of hours to train plan b clients
y = 0.87 hours
