In Exercises 1–4, find each sum or difference.
start fraction 5 over 10 end fraction minus start fraction 3 over 10 end fraction
A. one-fifth
B. start fraction 8 over 10 end fraction
C. start fraction 42 over 5 end fraction
D. one-tenth
Answer:
a 1/5
Step-by-step explanation:
because if you do 5/10-3/10 you get 2/10
then you simplify by 2 which means you do 2 divided by 2 which
is 1 then you do 10 divided by 2 which is equal to 5 so your
answer is indeed 1/5
A machine can enlarge a 6– inch by 4– inch regular photograph to any of the dimensions shown in the table below. Which equation represents the relationship between I, the length of the enlargement, and w, the width of the enlargement?
Answer:
c. w = 2/3l
Step-by-step explanation:
for a., none of the values fit so it can't be a.
for b., the second row fits but none of the others do so it can't be b.
for c., every single row fulfills the equation so the answer is c.
for d., the first row fits but none of the others do so it can't be d.
since there are only four choices it's fine to plug and test.

Use the figure and flowchart proof to answer the question: Which theorem accurately completes Reason A?
A. Alternate Interior Angles Theorem
B. Corresponding Angles Theorem
C. Alternate Exterior Angles Theorem
D. Same-Side Interior Angles Theorem
Answer:I believe that it would answer D) same side interior angles.
Same side interior angles or consecutive angle always add up to 180 degrees
A cannot be because the angles that the diagram is telling us are not alternate interior angles, alternate interior angles would be angle UQR and angle QRZ
B cannot be because they are not corresponding and also they are not Alternate Exterior angles. Which left us with D.

At a bus station, buses depart at a rate of 3 every 10 minutes. At this rate, how many buses would you expect to depart in one hour?
A. 6 B. 15 C. 18 D. 30
Answer:
Well, there are 60 min. in one hour, so 10*6=60. Then we have to multiply 3 by 10 as well. So the answer is D: 30 busses.
Answer: the answer is c.(18)
Step-by-step explanation:
If 3 depart every 10 minutes there are 60 minutes in an hour. So 3 buses times 6 10’s would = 6x3=18
What value of x satisfies the equation: 6(x-3)+10=2(3x-4)
A) x=22
B) x=-22
C) x=20
D) x=6
Answer:
A)x=22
Step-by-step explanation:
when you substitute in 22 both sides of the equation equal 124
Answer:
Everything; A, B, C, and D.
Step-by-step explanation:
We have the equation:
[tex]6(x-3)+10=2(3x-4)[/tex]
Let's solve for x. On the left, distribute:
[tex](6x-18)+10=2(3x-4)[/tex]
Distribute on the right:
[tex]6x-18+10=6x-8[/tex]
Combine like terms on the left:
[tex]6x-8=6x-8[/tex]
We can see that both the left- and right-hand side are equivalent.
Therefore, any and all values of x will satisfy our equation.
So, our answer is A, B, C, and D.
Or, picking any single one should be correct.
Using the distributive property, write two expressions equivalent to 35 + 28. (hint find the GCF of the numbers, then write expressions)

Which of the following pairs of base and height produces the greatest area? All measurements are in centimeters.
a) b = 4, h = 3.5
b) b = 0.8, h = 20
c) b = 6, h = 2.25
d) b = 10, h = 1.4
The greatest area can be using the measurement b = 0.8, h = 20.
What is area?The area is the region bounded by the shape of an object. The space covered by the figure or any two-dimensional geometric shape, in a plane, is the area of the shape.
For the greatest area we can use the measurement:
a) b = 4, h = 3.5
area= 4*3.5=14
b) b = 0.8, h = 20
area= 0.8*20 =16
c) b = 6, h = 2.25
area= 2.25*6 = 13.5
d) b = 10, h = 1.4
area= 10*1.4=14
whether we take area of any figure the greatest area can be possible using the measurement b = 0.8, h = 20..

A truck whose bed is 2.5m long, 1.5m wide, and 1.0m high is delivering sand for a sand-sculpture competition. About how many trips must the truck make to deliver [tex]7m^{3}[/tex] of sand?
Answer:
68.6 Trips
Step-by-step explanation:
2.5m+1.5m+1.0=5
5m per trip
7m^3=343
divide the amount that can fit in each trip (5m)
by the amount of sand needed for the sculpture. (343m)
343 /5=68.6
Find a common multiple between 30 and 42 that is bigger than them.
(Note: I'm not finding the LCM I just need a multiple bigger than them)
Answer:
210
Step-by-step explanation:
GCF(30,42) = 6
LCM(30,42) = ( 30 × 42) / 6
LCM(30,42) = 1260 / 6
LCM(30,42) = 210
The price of Stock A at 9 A.M. was $13.64. Since then, the price has been increasing at the rate of $0.06 each hour. At noon the price of Stock B was $14.39. It begins to decrease at the rate of $0.11 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?
Answer: In about 3 hours and 21 minutes the prices of the two stocks will be the same at $14.02
Step-by-step explanation: We can begin by calculating the value of stock A at noon by adding $.06 per hour or 3 hours, $0.18 to its 9am price. $13.64 + 0.18 = 13.82
Then set up the equation to find the point where the prices are equal:
x is the amount of time in hours.
.06x + 13.82 = -.11x + 14.39
Add .11x to both sides and subtract 13.82 from both sides
.06x + .11x = 14.39 - 13.82
.17x = 0.57
x = 3.353 hours
To get minutes instead of a decimal, multiply .353 × 60 ≈ 21 minutes
The time is 3:21
The increase in price is for stock A is about $0.20
13.82 + .0.06(3.353) = $14.02
Stock B decreased by $0.37
14.39 - 0.11(3.353) = $14.02
10n + 7 > n - 3 (5 - 3n)

The amount of hay Mo eats is
the amount that Larry and Curly eat combined.
( Don't answer just for the points) asking again bc 2 people answered but not with the answer
Answer: If Mo eats 1 1/2 pounds of hay, Larry and Curly together eat less.
Larry and Curly eat 17/12 or 1 5/12 pounds of hay together.
Mo eats more hay than Larry and Curly combined.

⚠️Which ordered pair is the solution to this system of equations?⚠️
Answer: A
Step-by-step explanation: when you plug 3 into both equations you get 5
Answer:
A
Step-by-step explanation:
to make this simple, plug the x-coordinate of each answer choice into x in each of the equations and plug the y-coordinate of each answer choice into y in each of the equations. if BOTH equations come out to be true, this is the solution.
ex:
y=3x-4
y=x+2
plug in (3,5)
5=3(3)-4 is correct
5=3+2 is correct
so, (3,5) is the solution.
