Answer:
See solution below
Step-by-step explanation:
Given the following expression
1) 24+r
If r = 9
24 + r = 24+9
= 33
2) 2a+3
If a = 10
Substitute
2(10)+3
= 20+3
= 23
3) BC+12.3
b = 9
c = 4
Substitute
= 9(4)+12.3
= 36+12.3
= 48.3
4) p÷q
Given p = 24 and q = 8
p÷q = 24÷8
p÷q = 3
5) 4c-7.8
If c = 4
Substitute
= 4(4)-7.8
= 16-7.8
= 8.2
6) c-a
a = 3
c = 17
Substitute
= 17-3
= 14
Hence c-a = 14
7) a ÷ 2c ; a = 20, c = 2
Substitute
a÷2c
= a/2c
= 20/2(2)
= 20/4
= 5
8) 3x-14
If x = 5
Substitute
= 3(5)-14
= 15-14
= 1
9) 1.5 + y² ; y = 6
Substitute
= 1.5+6²
= 1.5+36
= 37.5
10) t/5 + 6 ; t = 45
substitute the value of t given into the expression
= 45/5 + 6
= 9 + 6
= 15
A. (−13)+(−7)= b. (−15)− (−15)= c. (2)∙ (−13)= d. (−44)÷ (11)= e. (−3)+(−5)+(8) +(25)= f. 3+4=4
Answer:
See answer below
Step-by-step explanation:
In this case, this is just sum, substraction and divisions using the properties or the signus. This is just basic operations using the negative and positive numbers.
To do this easily you just have to remember the following:
1. Numbers with same sign, must be summed and put the sign that have either number.
2. Numbers with different sign, must be substracted and then put the sign of the highest number.
3. If you have a multiplication or division:
- Same signs multiplied or dividied (Either positive or negative), result always positive.
- Different signs multiplied or dividied (positive and negative), result always negative.
Following this simple rules, you'll be able to solve almost any exercise of this.
Now, according to the rules above, let's solve the exercises:
A. (-13) + (-7)
In this case, you have two negative numbers, and one positive sign between them. Apply the 3rd rule. The negative sign remains and then:
-13 - 7
Now 1st rule applied, sum the numbers and let the same sign:
-13 - 7 = -20.
B. (-15) - (-15) = 0.
Applying 3rd rule and then 2nd rule, we have a subtration of -15 + 15.
C. (2) * (-13) = -26
Applying the 3rd rule, we have positive and negative, result always negative.
D. (-44) / 11 = -4
3rd rule applied.
E. (-3) + (-5) + 8 + 25 = 31
Applied 3rd and 1st rule.
I don't understand the f, but you can use the rules here and get the final answer of that one.

If a hexagon is worth 5 and a triangle is worth 3, what is a circle
Answer:
6
Step-by-step explanation:
Call pentagon p, circle c and triangle t
We have 2c + 2p = 2p + 2t + c
p = 5, t = 3 so
2c + 2(5) = 2(5) + 2(3) + c
2c + 10 = 10 + 6 + c
2c = 6 + c
c = 6
6 answer
Call pentagon p, circle c and triangle t
We have 2c + 2p = 2p + 2t + c
p = 5, t = 3 so
2c + 2(5) = 2(5) + 2(3) + c
2c + 10 = 10 + 6 + c
2c = 6 + c
c = 6

which graph models the solution of the Inequality -6 ≤ -3x
We know that graph (B) models the solution of the given inequality -6 ≤ -3x.
What are graphs?Drawing the curve that represents a function on a coordinate plane is known as graphing a function. Every point on the curve will satisfy the function equation if the curve (or graph) represents the function.Line graphs, bar graphs, pie charts, scatter plots, and histograms are examples of common graph types. Graphs are a fantastic tool for displaying statistics and visualizing data. To depict numerical data that is unrelated to one another, a bar graph or chart may be utilized.So, in the given inequality:
-6 ≤ -3xWe know that:
Make x subject: -6/-3 ≤ xWhich is 2 ≤ x, represented in a graph (B).Therefore, we know that graph (B) models the solution of the given inequality -6 ≤ -3x.

Find the slope of the line that passes through
(7,-1) and (9,0)
Answer:
1/2 or 0.5
Step-by-step explanation:
so to find the slope of two points you use the slope formula which is rise over run, y2-y1/x2-x1. so that would be -1-0/7-9. leading to -1/-2. so the slope is 1/2 or 0.5.

Given the Standard Form equation y - 6x = 4
What is the slope and y intercept?
someone plz explain
Answer: 6 is the slope and 4 is the y-intercept.
Step-by-step explanation:
Based on the question, I feel this is the best way to answer your question. I'm assuming you are in a basic graphing class.
The best, most useful thing for you right now would be to learn slope-intercept form, y = mx + b, where m and b are constants.
Simply add 6x to both sides to get into this form
y = 6x + 4.
In slope-intercept form, m is the slope, and b is the y-intercept. Thus, 6 is the slope and 4 is the y-intercept.

Answer:
x= -3/2 or x=1.
Step-by-step explanation:
First, make the equation into a factorable form by subtracting 2 from each side to get 2x²+x-3=0. Then factor that into (2x+3)(x-1)=0. Then, you would do 2x+3=0, 2x=-3, x= -3/2. After that, do the second equation x-1=0, x=1.

10. Multi-Step Mrs. Sullivan calculates that she
needs 12 gallons of paint to paint her house.
She already has 8 quarts of the paint she
needs. How many gallons of paint should
she buy?
Answer:
Amount of paint to be bought = 10 gallons
Step-by-step explanation:
Amount of paint needed by Mrs. Sullivan to paint her house = 12 gallons
She is already having paint = 8 quarts
Since, 1 quart = 0.25 gallons
Therefore, 8 quarts = 8 × 0.25
= 2 gallons
So, amount of paint she is already having = 2 gallons
Amount of paint to be bought = 12 - 2
= 10 gallons

Choose the solution that is graphed on this number line.
A. x < 2
B. x > 2
C. x ≤ 2
D. x ≥ 2
c
Step-by-step explanation:
if you look at the graph, if there is a closed circle, that means x can be equal to whatever number the circle is on. if the circle is open, that means you don't include that number, which is in this case two. a closed circle means that x can be equal to 2. since the arrow is going from 2 to the left, x can be anything from two to any real numbers to the left. therefore, since to the left goes to numbers smaller than 2, x can either be equal to or less than two.
The solution of the inequality 3/4 x - 2/3 ≤ 5/6 which is graphed on given number line is x ≤ 2.
Here inequality is given as;
3/4 x - 2/3 ≤ 5/6
What is inequality?
A statement of an order relationship; less than, greater than, greater than or equal to, less than or equal to, between two algebraic expression is known as inequality.
Now,
3/4 x - 2/3 ≤ 5/6
3/4 x - 2/3 + 2/3 ≤ 5/6 + 2/3
3/4 x ≤ 7/3
Now multiply both side by 4/3;
[tex]\frac{3}{4} x *\frac{4}{3} \leq \frac{7}{3} *\frac{4}{3} \\x\leq \frac{28}{9} \\x\leq 3.11\\[/tex]
Hence, The solution of the inequality 3/4 x - 2/3 ≤ 5/6 which is graphed on given number line is x ≤ 2.

graph the image of M (–10,–7) after a rotation 180° counterclockwise around the origin.
Answer and Step-by-step explanation:
The point will be (7, 10).

The image of the point M is M' = (10, 7) as shown in the graph below.
What is Coordinate Geometry?One of the most intriguing ideas in mathematics is called coordinate geometry. By using graphs with curves and lines, coordinate geometry (also known as the analytic geometry) explains how geometry and algebra are related.
As per the given data:
Coordinates of point M = (-10, -7)
Rotation to be given = 180° (counter - clockwise)
For drawing the image of point M (-10, -7):
Step 1: Create a line connecting the origin to the point M (-10, -7) and extending across the third and first quadrants.
Step 2: Modify the x and y coordinates signs to reflect the 180° rotation, then mark the point in the first quadrant.
The image of the point M is M' = (10, 7) as shown in the graph below.
Hence, the image of the point M is M' = (10, 7).
