Answer:
8
Step-by-step explanation:
The first division was ...
a/-2 = 8
Multiplying by -2, we have ...
a = (-2)(8) = -16
__
The second division was ...
8/b = -4
Multiplying by b/-4, we have ...
8/-4 = b = -2
__
Then the quotient of interest is ...
a/b = (-16)/(-2)
a/b = 8

Answer:
42
Step-by-step explanation:
You get 42 by looking at the denominators 7 and 21. You times by 3 to get from 7 to 21, so you times 14 by 3 to get n, which is 42.
Answer:
42
Step-by-step explanation:
On the bottom 7 was multiplied by 3 so you would do the same to 14.

can someone help me find the area please?
Answer:
100 in ^2
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 ( b1+ b2) *h where b1 and b2 are the lengths of the bases and h is the height
A = 1/2 ( 16+9) * 8
= 1/2 ( 25) *8
= 100 in ^2

Answer:
5*10^10
Step-by-step explanation:
10 to the power of 10 is 10^10.
10^10*9 is 90000000000
10^10*4 is 40000000000
90000000000-40000000000=50000000000

Find the zero of the function.
f(x) = -6x + 18
Answer:
(3,0)
Step-by-step explanation:
f(x) = -6x + 18
Let f(x) = 0
0 = -6x + 18
Subtract 18 from each side
-18 = -6x
Divide by -6
-18/-6 = -6x/-6

A. Rewrite the equation of the line in slope intercept form
B. Identify the slope and y intercept
(Show steps )
Answer:
Rewriting the equation in slope intercept form is: Y= -8x+4
Step-by-step explanation:
Im sure there's a faster way to solving this, but I'm just in 8th grade so I'm gonna apply what I know so far.
First of all, we know that our slope is -8... so we have y= -8x so far
From here, to find out y intercept I knew that our slope deals with all the points assigned, therefore we know that from -4 the change would be -8 so we get -12. We can also go the other way. This means that we plus 8 to get positive 4. (Side note: the change in our x value is 1 so we know that our y intercept is always dealing with a 0 in the x position) ex. (0,9) the y intercept would be 9.
To wrap things up, the slope is -8 and the y intercept is 4.
We then get Y= -8x+4
Hope this helps! :)

What is N + (n+2) when N = 62 and n = 64
help please (: this has something to do with geometry!!
Answer: x=64°
Step-by-step explanation:
According to the diagram, the two intersecting lines are perpendicular. That means each part is 90°. Since the left side is labelled to be 180°, we know that the sum of the right side is also 180°.
26+x+90=180 [combine like terms]
116+x=180 [subtract both sides by 116]
x=64°
Now, we know that x=64°.
On the other hand, we can see that 26+x=90. We can also use that to solve for x.
26+x=90 [subtract both sides by 26]
x=64°
How do I find the missing side using the Pythagorean theorem?
Answer:
6.7082039325 If you want to round it is 7
Step-by-step explanation:
a squared + b squared = c squared, where as 6 is a, 3 is b, and x is c.
6 squared + 3 squared is 36+9=45, so x is the square root of 45.

The clocks shows when Tisa’s movie started and ended. How long did the last movie last? Plz hurry I need to finish
Answer:
it last 2 hours and 30 min
Step-by-step explanation:
-3/5 x = 6 how do I solve for x
Divide the sides of the equation by -3/5 :
-3/5 ÷ -3/5 x = 6 ÷ -3/5
1 x = 6 × -5/3
x = -30/3
x = -10
and we're done.

Question 6(Multiple Choice Worth 1 points) (02.05 MC) Choose the table that represents g(x) = 4⋅f(x) when f(x) = x − 5. x g(x) 1 −4 2 −3 3 −2 x g(x) 1 −16 2 −12 3 −8 x g(x) 1 −20 2 −18 3 −16 x g(x) 1 −1 2 −2 3 −3
Answer: (b)
x g(x)
1 -16
2 -12
3 -8
If g(x) is 4*f(x), then we can find g(x) by multiplying 4 by x-5
g(x) = 4(x-5)
= 4x-20
Now we can plug in 1,2, and 3 for x to see which table makes sense.
g(1) = 4(1) - 20
= -16
g(2) = 4(2) - 20
= -12
g(3) = 4(3) - 20
= -8
hope this helps
Answer:
x g(x)
1 -16
2 -12
3 -8

Option C; 4. Multiply the original measure by the conversion factors.
5. Check for reasonableness
To answer this question, let us take an example of converting from inches to centimeters.
Let us convert 10 inches to centimeters.
First step is to identify the measure to be converted which in this case it is inches that is the measure.
Second step is to write the conversion factors which is;
1 inch = 2.54 cm
Third step is to cancel the units; In this case the units to be canceled will be inches.
Fourth step is to multiply the original measurement by the conversion factor to give; 10 × 2.54 cm = 25.4 cm
Fifth step is to check for reasonableness by trying to check if using another number will give a reasonable answer.

Answer:
A =72 in^2
When dilated
=1152 in ^2
Step-by-step explanation:
The area of the triangle is
A = 1/2 bh
We need to convert the units to match
2 ft= 24 inches
A = 1/2 ( 24*6)
A = 1/2 (144)
A =72 in^2
When dilated 6 inches *4 = 24 inches
24 inches *4 = 96 inches
A = 1/2 ( 96*24)
= 1/2(2304)
=1152 in ^2
the question is 7a + 10 = 2a
Answer:
a = -2
Step-by-step explanation:
Subtract 10 from both sides:
7a + 10 - 10 = 2a - 10
Simplify:
7a = 2a - 10
Subtract 2a from both sides:
7a - 2a = 2a - 10 - 2a
Simplify:
5a = -10
Divide both sides by 5 and simplify:
a = -2
Answer:
A = -2
Step-by-step explanation:
Subtract 10 from both sides:
7a + 10 = 2a -10
Simplify the expression, 7a = 2a - 10
Subtract 2a from both sides next
7a - 2a = 2a - 10 - 2a
Subtract 7a - 2a
5a = -10
5a / 5 = -10/5
a = -2

George’s age is three times that of his brother. When you add George’s age to his brother’s, you get 24. How old is each brother?
a) Write an equation that represents the situation. Explain any variable used.
b) Solve the equation from Part (a). Show your work. State your solution as a complete sentence.
Answer:
G=18
Step-by-step explanation:
George-G
1/3G+G=24
4/3G=24
3/4*4/3G=24*3/4
G=18
George will be 18 years old there we can find his brothers age by dividing it by three thus 18/3=6
Answer:
George is 18 and his brother is 6
Step-by-step explanation:
let the brother's age be n then George's age is 3n ( 3 times his brother's age )
n + 3n = 24 ( sum of their ages )
4n = 24 ( divide both sides by 4 )
n = 6
and 3n = 3 × 6 = 18
George is 18 years old and his brother is 6 years old.
