7. Here's how Mo solved the subtraction problem
635 - 813:
635
- 813
- 222
Mo did this by working from right to left, saying
5 – 3 = 2
3 - 1 = 2
6 - 8 = -2
a. Is Mo's answer right?
b. Solve
6(100) + 3(10) + 5(1)
- [8(100) + 1(10) + 3(1)]
by working with expanded forms. Discuss how
Mo's work compares with your work in expanded
forms.
Answer:
Mo's answer is wrong.
635 - 813
= -178
Step-by-step explanation:
a. Is Mo's answer right?
No, Mo's answer is incorrect
Mo did this by working from right to left, Just like Subtraction
• 3 - 5 =
We that 1 from the number in tens , add that to 3, making it 13
13 - 5 = 8
• 1 - 3 = 7
The one above becomes 0, because 1 was taken from it. We add 1 to 0, making it 10
10 - 3 = 7
• 8 - 6 = 1
The 8 above reduces to 7 because 1 has been taken from 8.
Hence: 7 - 6 = 1
635 - 813
= -178
The answer is minus 178 because, we are subtracting the bigger number form the smaller number.
b. Solve
6(100) + 3(10) + 5(1)
- [8(100) + 1(10) + 3(1)]
by working with expanded forms. Discuss how Mo's work compares with your work in expanded forms.
= -1(100) + 7(10) + 8(1)
Help please. I'll give the Brainliest.
Answer:
Options 1,2,3 are correct statements
The first values in an ordered pair ( the coordinates) are the domain : ( -3,-2,-1,0,1)
The second values are the range : (-1,1,2,3,4,5)
One input should have only one output for a function.
But -1 input has 2 outputs: -1 and 3.
Thus, it is a relation and not a function.
Hope it helps :)

Find 18% of $25. Please i need help
Answer:
4.50 i think
Step-by-step explanation:
a product that normally costs $25 with a 18 percent discount will cost you $20.50, and you saved $4.50. You can also calculate how much you save by simply moving the period in 18.00 percent two spaces to the left, and then multiply the result by $25 as follows: $25 x . 18 = $4.50 savings.
Answer:
4.5
Step-by-step explanation:
you multiply 18 and 25 to get an answer of 450 then divided it by 100 to get 4.50

The Mulder Farm has 600 acres of land allotted for raising corn and wheat. The cost to cultivate corn is $40 per acre. The cost to cultivate wheat is $25 per acre. The Mulders have $18,000 available to cultivate these crops. How many acres each crop should the Mulders plant
Answer: Corn = 200 acres
Wheat= 400 acres
Step-by-step explanation:
Let the number of acres of corn = c
Let the number of acres of wheat = w
The Mulder Farm has 600 acres of land allotted for raising corn and wheat. This will be:
c + w = 600
c = 600 - w
Cultivation cost equals:
= 40c + 25w = 18000
Since c = 600 - w, we slot it into the equation
40c + 25w = 18000
40(600 - w) + 25w = 18000
24000 - 40w + 25w = 18000
Collect like terms
24000 - 18000 = 40w - 25w
6000 = 15w
w = 6000/15
w= 400
400 acres of wheat will be planted
Since c + w = 600
c = 600 - 400
c = 200
200 acres of corn should be planted

Maggie's brother is 4 years younger than twice her age. The sum of their ages is 17.
How old is Maggie?
Answer:
Maggie is 7 years old
Step-by-step explanation:
m+2m-4=17
3m-4=17
3m=21
m=7
Answer:
Maggie is seven years old
Step-by-step explanation:
Maggie's Brothers Age = B
Maggie's Age = M
2M - 4 = B
B + M = 17
Plug in 2M - 4 for B
( 2M - 4 ) + M = 17
Combine Like Terms
3M - 4 = 17
Add 4 to either side
3M = 21
Divide either side by 3
M = 7
Check your answer
2M - 4 = B -> 2 x 7 - 4 = B -> 14 -4 = B -> B = 10
B + M = 17 => 7 + 10 = 17 => 17 = 17
Which represents where f(x) = g(x)?
Answer:

Step-by-step explanation:
Both intercept twice at 0 and -4.
which could be the side lengths of a right triangle?
Answer:
B
Step-by-step explanation:
90+45+45=180
All triangles equal 180.
Its B because if one angle is 90° then the other angles will equal each other. It cant be 60° and 30° because they dont equal, so your final answer is B.

Marietta was given a raise of $0.50 per hour, which gave her a new wage of $18.75 per
hour. Enter and solve an equation to determine Marietta's hourly wage, x, before the raise.
Complete the explanation to show that your answer is reasonable.
The equation is
= 18.75.
Marietta's hourly wage before the raise was $
Marietta received a raise that was less than $1.00 per hour, so her new hourly wage should
be less than $ (select) + $1 = $19.25. Her new hourly wage of $18.75 is less than $19.25,
so the answer is reasonable.
Answer:
11.50
Step-by-step explanation:
The new wage is equal to the old wage plus her raise, so:
x + 0.75 = 12.25
or
x= 12.25-0.75
Meaning x is her original wage, being $11.50

Answer:
(- ∞, - 1 )
Step-by-step explanation:
Given
4(x + 2) < - [tex]\frac{1}{2}[/tex] (4x - 4) ← distribute parenthesis on both sides )
4x + 8 < - 2x + 2 ( add 2x to both sides )
6x + 8 < 2 ( subtract 8 from 2 )
6x < - 6 ( divide both sides by 6 )
x < - 1
x ∈ (- ∞, - 1 ) ← in interval notation
$3.50 per pound for potato salad OR 1.5 pounds of potato salad for $4.50
Answer:
1.5 pounds of potato salad for 4.50 would be cheaper
Step-by-step explanation:
because if you divide 3.50 by two you get 1.75 and added back to 3.50 you can purchase 1.5 pounds for 5.25 which is more expensive than 4.50
Walking at a speed of 3 mph, Jack gets to school in 10 minutes and arrives at school right before the class starts. Today Jack needs to be at school 4 minutes earlier. How fast does Jack need to run this morning?
Answer:
Jack needs to run at a speed of 1/12 mph
Step-by-step explanation:
Mathematically;
speed = distance/ time
Distance = speed * time
10 minutes = 10/60 h = 1/6 hours
The distance to the school will be
Distance = 3 * 1/6 = 1/2 = 0.5 miles
Now, he needs to be at school 4 minutes earlier, time will now be 10 - 4 = 6 minutes
To get the speed here;
Recall that the distance from above does not change
So speed = 0.5/6 mph 0r 1/12 mph
8 taps can fill a tank in 27 min with the same rate of flow. If 3 taps go out of order how long will the remaining taps take to fill the tank
Answer:
pls 5 star
Step-by-step explanation:
8 taps can fill a tank in 27 minutes.
So,
1 tap can fill the same tank in time = 27 × 8 = 218 minutes
Therefore, 6 remaining taps can fill the same tank = 216/6
= 36 minutes
The remaining 6 taps will take 36 minutes to fill the same tank.

statement c is multiplication property of equality
i need help with this i am really bad at math
Answer:
You subtracted 25 from both sides.
Step-by-step explanation:
To move one part of the equation to the other side, you need to do the opposite. 25 is already negative(or being subtracted) so you need to add it to both sides to cancel it out on the left.
10x=-75+25
10x=-50
then divide both sides by 10
x=-5

Write a proof for the conjecture using the contrapositive.
If 5x + 7 = -13, then x = -4.
The contrapositive of this statement would be: "If x does not equal -4, then 5x + 7 will not equal to -13."
what is contrapositive?The contrapositive is defined as the inverse and converse of a conditional statement.
X is equal to 4 we know this is because the sign in between the number means greater than or equal to so 3 x 4 equals 12 which makes the equation on right true and on the left x.
So, the contrapositive of this statement would be:
"If x does not equal -4, then 5x + 7 will not equal to -13."

Anthony writes a numerical expression 2+10x3-2 and says that the expression has a value of 34. Is Anthony correct? Explain your answer.
Answer:
he is incorrect
Step-by-step explanation:
He is incorrect because 10 times 3 is 30, plus-minus 2 which is 30. So instead of 34, it is 30. or you can say Anthony is wrong. Following the order of operations, you would do the 10*3 first. Then, you would take the 30, and finish the equation from left to right. So you would add 2 to make it 32 and then subtract 2 to make it 30 again. So your final answer is 30, not 34. So Anthony is wrong.

The answer is y = 12x - 24
Use the form y = mx + b
If the points are (2, 0) and (3, 12) the slope is 12 which gives us m.
Since every time you go backwards once it goes down 12, (1, -12) is a point and then (0, -24) is a point that shows us the y-intercept which gives us b.
