Answer:
466 + 68
Step-by-step explanation:
We can easily check a subtraction problem with an addition problem.
Calculate the sum of the subtracted and the difference. If the sum is equal to the minuend in the original subtraction problem, the answer is correct.
Minuend - Subtrahend = Difference
466 + 68 = 534
The statement '534 – 68 = 466' is correct.
Hope this helps.
Answer:
68+566
Step-by-step explanation:
to tell if you have the right number or answer make sure if it's addition just subtract it and see what you get
An irregular hexagon has angles that measure the following. Angle 1: 2x + 15 Angle 2: 9x - 3 Angle 3: 77 Angle 4: 8x + 8 Angle 5: 13x Angle 6: x - 4 What is the value of x?
Answer: 19
Step-by-step explanation:
1) You combine like terms with all the angles
Ex. 2x + 15 + 9x - 3 + 77 + 8x + 8 + 13x + x - 4, which equals 33x + 93
2) You set up an equation using the formula for the sum of the interior angles
Ex. 33x + 93 = 180(n - 2)
3) Since a hexagon has 6 sides, n is 6
Ex. 33x + 93 = 180(6 - 2)
4) Solve like a regular equation
Ex. 33x + 93 = 180(6 - 2)
33x + 93 = 720
- 93 = - 93
33x = 627
- Divide 627 by 33
x = 19

I believe the answer is Simone. Simone in this case has 24 votes out of 60 that Dominick who planned to vote, so it should be her.
I am not sure but from what ik by the given information its Simone.
A roast beef sandwich costs $6.75. A customer buys multiple roast beef sandwiches. Write an equation that represents the situation. Use x to represent the number of roast beef sandwiches. Then determine how many sandwiches the customer buys.
Amount used for payment: 80$
The change received: $19.25
An equation that represents this situation is _____
The customer buys ____ sandwiches
Please help me with these two questions.
Answer:
1. 6.75x or (6.75, 1)
2. He buys 9 sandwiches.
Step-by-step explanation:
For the first one, we know that he pays $6.75 for each sandwich, so if x equals the number of sandwiches, when written out it would be 6.75x
For the second one, we have to divide it up and solve one step at a time, and when we start solving them, we will find the pieces to figure out the other problems. Let's start with how much he paid. We know that he paid $80, but we have to remember that he got change back. So to find out how much he truly paid, we subtract the 19.25 from the 80. When we do this, we get 60.75. Now, to find out how many sandwiches he got, we can use how much he paid for each one. We know that he paid $6.75 for each one, and in total he spent $60.75. So to find out, we can simply divide 6.75 into 60.75, and we get 9. So now we know that he bought 9 sandwiches.
I hope this helps :)

An ethanol railroad tariff is a fee charge for shipments of ethanol on public railroads. The Agriculture Marketing Service publishes tariff rates for railroad-car shipments of ethanol in the Biofuel Transportation Database. Assuming that the standard deviation of such tariff rates is $1150, determine the probability that the mean tariff rate of 500 randomly selected railroad-car shipments of ethanol will be within $100 of the mean tariff rate of all railroad-car shipments of ethanol.
Answer:
The appropriate response is "0.9476".
Step-by-step explanation:
The given values are:
Standard deviation,
[tex]\sigma=1150[/tex]
Randomly selected railroad-car shipments,
n = 500
As we know,
⇒ [tex]\sigma \bar{x}=\frac{\sigma}{\sqrt{n} }[/tex]
On substituting the values, we get
⇒ [tex]=\frac{1150}{\sqrt{500} }[/tex]
then,
⇒ [tex]=P(-1.94<Z<1.94)[/tex]
⇒ [tex]=P(Z<1.94)-P(Z < -1.94)[/tex]
On using the table of P, we get
⇒ [tex]=0.9738 - 0.0262[/tex]
⇒ [tex]=0.9476[/tex]
I NEED THE ANSWERS WITH AN EXPLANATION PLS!!
1. The perimeter = 120 m; length = 45 m ; breadth = ____
2. Perimeter of a rectangle = 250 m; breadth = 50m; length = _____
1) to find perimeter we multiply length and breadth so to find breadth we divide the perimeter by the length. which means, 120 divided by 45 and its 62.5 so the answer for the 1st question is 62.5
2. if we multiply length with breadth to find perimeter, just like the first one we divide the perimeter by the breadth. which means, 250 divided by 50 and it will be 5

Answer:
a = -29
Step-by-step explanation:
[tex]12=\frac{a+5}{-2} \\\\-24=a+5\\a=-24-5\\a=-29[/tex]
1st step is to multiply -2 on both sides
Step-by-step explanation:
12× -2 = a+5
-24 = a +5
a = 24+ 5

please help,Explain how solving -7y > 161 is different from solving 7y > -161.
Answer:
-7y > 161
7y < -161
y < -23
7y > -161
y > -23
So, your answer is: -7y > 161 is equal to y < -23, and 7y > -161 is equal to y>-23.

The graph of the function f(x)=-(x+6)(x+2) is shown below. What statement about the function is true ?
A.) the function is increasing for all real values of x
x < -4.
B.) the function is increasing for all real values of x where
-6 < x < -2.
C.) the function is decreasing for all real values of x where
x < -6 and where x > -2.
D.) the function is decreasing for all real values of x where
x < -4.
Answer:
A
Step-by-step explanation:
in x<-4 the derivative is positive so the function is increasing.
in x>-4 the derivative is negative so the function is decreasing
increasing in (-infinity,-4)
decreasing in (-4,infinity)

Nigel drew a parallelogram with a base length of 6 3/4 inches and a height of 2 5/8 inches. Krista made a scale drawing of Nigel's parallelogram using a scale factor of 1/3 .
Answer: Krista's drawing would have a base length of 2 and 1/4 inches and a height of 7/8 inches
Step-by-step explanation: First you do 6 divided by 3 which is 2 then you make 3/4 in twelfths and you get 3/12, then you simplify that into 1/4. Then
you combine those and get a base length of 2 and 1/4 inches.
Next, you do 2 and 5/8 divided by 3. Since 3 is less than 2 your answer would have to be less than 1. What i would do is make 2 and 5/8 into a fraction, which would be 21/8. then to make it easiest you multiply that by 1/3. which would equal 21/24. and then you simplify by dividing that by 3. Which would give you 7/8, which would give you your answer.
So the final answer would be a base length of 2 and 1/4 inches and a height of 7/8 inches.

Naomi used a rectangle, a square, and a right triangle to form the following figure.
What is the area of the shaded region of the figure in
eters?
A-120 cm2
B-102 cm2
C-18 cm2
D-9 cm2
Answer:
B. 102 cm
Step-by-step explanation:
The first step would be to find the area of the whole figure and subtract the white area off.
So, to do that simply multiply the length x width to get the area of the whole figure.
20 x 6 = 120(area of the whole figure)
Next, 20-11 = 9 is the length of the figure and because the square has a side length of 3, the other side would also have to be 3.
3 x 3 = 9(area of the smaller square.
9-3=6
6-3=3
Area of triangle = Base x Height Divided by 2.
So, 3x6=18/2=9
9+9=18
Finally, subtract 18(total area of white smaller shapes) from 120 and you will get the final answer
102 cm.

Bob has a dollar bill. He uses 1/4 of it to buy a coupon.
Imagine this happening:
1$
Uses 1/4
So... Let's look at what I've given you.
2/4=0.5
3/4=0.75
Well, let's stretch some things a liiiiitle bit.
Bob has a dollar bill blah blah...
We get to 1/4.
Le's make that 2/4.
2/4 is 0.5
So... By stretching the truth
We can infer that
If we put 1/4 back
(Oh no now the word problem creators are mad at me ;) lol)
Anyways, we can infer that by putting 1/4 back
That since 3/4 is 0.75
Then what's connected to 0.5 and 0.75?
The answer, my friend,
Is 0.25
