Colleen divided integer a by −2 and got 8. Then she divided 8 by integer b and got −4. Find the quotient of integer a and integer b.
/ = division
a/b =
9514 1404 393
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
f (2b) if f (x)= -2x + 4
Answer:
f(2b) = -4b + 4
Step-by-step explanation:
Step 1: Define
f(x) = -2x + 4
f(2b) is x = 2b
Step 2: Substitute and Evaluate
f(2b) = -2(2b) + 4
f(2b) = -4b + 4

=-3.10-7
=-30-7
=-37
Answer:
Your final answer will be
−37
Step-by-step explanation:
(2−5)(3+7)−(4+3)
= −3(3+7)−(4+3)
= (−3)(10)−(4+3)
= −30−(4+3)
= −30−7

Solve the y for the equation 5x-2y=10
Answer:
y = 5/2x - 5
Step-by-step explanation:
Step 1: Write equation
5x - 2y = 10
Step 2: Solve for x
Subtract 5x on both sides: -2y = 10 - 5xDivide both sides by -2: y = -5 + 5/2xRewrite: y = 5/2x - 5Answer:
y = (5/2)x - 5
Step-by-step explanation:
5x-2y = 10
Subtract 5x from both sides
-2y = 10 - 5x
Rearrange
-2y = -5x + 10
divide both sides by -2 to isolate y
y = (5x/2) + (10/-2)
y = (5/2)x - 5
Find the value of x in each of the following
a) 2x/3= 8
b) 3x/2=6
Answer:
A) X = 12
B) X = 4

B) 3x/2 = 6
Multiply each side by 2 to get rid of the fraction.
3x = 12
Divide by 3.
x = 4

One week, Brooklyn earned $179.30 at her job when she worked for 11 hours. If she is paid the same hourly wage, how many hours would she have to work the next week to earn $244.50?
Answer:
Brooklyn would get paid 16.30 hourly. So she will have to work 15 hours the next week to earn 244.50.
Step-by-step explanation:
Divide 179.30 by 11 and you would get 16.30 which is her hourly wage. Then you divide 244.50 by 16.30 to see how many hours she would have to work to earn 244.50.
Answer:
15 Hours
Step-by-step explanation:
179.30 / 11 = $16.3 an hour
244.5 / 16.3 = 15 hours
What is 10 times greater than 2000
Answer:
20,000
Step-by-step explanation:
Let's take it step-by-step
10 times greater than 2,000
10 x 2 = 20, 10 x 20 = 200, 10 x 200 = 2,000, 10 x 2,000 = 20,000
just remember to add a zero after each number so, if you have 10 x 20, just take the 2 and but a zero, 20, 10 x 20 = 200, Etc.
If you need more help let me know :)
Ten times greater than 2000 is 2000.
How to find out how many times greater or less given quantities are relative to each other ?To find how much greater one quantity is to other just divide other quantity by one quantity.If how many times is given and have to find greater just multiply the given quantity by the given times.
In the given question 10 times greater than 2000 is 2000 multiplied by 10 = 20000
To reverse check divide 20000 by 2000 and the result should match the previous result you have obtained.

Is the following number irrational?
-8.7
Answer:
No.
Step-by-step explanation:
Rational numbers are any of the following:
Integers (positive whole numbers, negative whole numbers, or zero).Fractions e.g. 3/4Terminating (with an end) or repeating decimals e.g. 0.2 or 0.333333... or 0.343434...Irrational numbers are thus defined as:
Non-terminating (unending), non-repeating decimal numbers. e.g. π, surds ( [tex]\sqrt{2}[/tex] ).This means that -8.7 is not irrational, as it is not an unending, non-repeating number: an easy way to remember how to answer this is to look at whether the number has been expressed in decimal form if it has (unless you have been told that it has been rounded) it must be rational, as it can be written as a decimal number.
