Step-by-step explanation:
you will see, this is totally easy. so, once you understand that principle, I am sure you will agree with me that this costs more time putting it in here than just doing it yourself in the future.
you need to consider for addition and subtraction every variable combined with an exponent a different thing, a fruit for example.
you know exactly what to do, when you are being asked to add 3 apples to 2 apples, right ?
or, when are are asked to add 4 apples and 2 pears to 3 apples and 2 pears.
in the first case we simply get 5 (2+3) apples.
in the second case we get 7 (3+4) apples and 4 (2+2) pears.
and nothing else happens here.
we could call x² apples, y² pears, y³ plums, x kiwis, t strawberries, t² raspberries. and the constants could be another fruit or grams of sugar.
now, we simply combine the "fruits" that belong together. there is nothing more to this.
5x² + 3y³ - 4x² = x² - 3y³ (because 5-4 for x²)
y³ + 2y³ - 8 + 2 = 3y³ - 6 (1+2 for y³ and -8+2 constant)
9 - 3x - 4x + 2x - 12 = -5x - 3
-6t + 4t² - 6 + 7t - 4t² = t - 6 (4-4 for t², -6+7 for t)
Solve for m.
−48=12(m+4)
Enter your answer in the box.
Answer:
-8
Step-by-step explanation:
First, you distribute the right side
-48 = 12(m+4)
-48 = 12(m) + 12(4)
Simplify:
-48 = 12m+48
Solve for m
-96 = 12m
m=-8
Answer:
-8
Step-by-step explanation:
-48/12 = m+4
(-48/12) -4 = m
m = (-4) - 4
m = -8

What is the diameter of a plate with circumference of 25 cm.?
Help please....If you can, draw on the attachments.
Answer:
Problem 3: Just 33 draw 4 boxes of 11 and one with 11
Problem 4: 30
Problem 5: Naomi
Step-by-step explanation:
For problem three since you are multiplying the same equation by 4 its basically (2+9)+3(2+9) so you can just cancel out the 2+9 from both and you are left with 3(2+9) which is just 33
For problem 4 100-(12x4)=52 and 10+(3x4) = 22 and when you subtract the two (52-22) you get 30
For problem 5 you get 18 with your equation and so since Carlos' equation gets 9 and Miranda gets 24 and Will gets 35 the only one left is Naomi which also gets 18 just like you.

I don't completely understand what you were asking, but if you were counting by 7's, 91 would be after 84 instead of just 90.
Answer:
7
Step-by-step explanation:
7x14=91, so 1 is not a multiple of 90. Don't really understand tho, plz comment if this is not what you meant.
A. 6 m
B. 9 m
C. 12 m
D. 15 m
Evaluate the equation.
-8x = -90
A. x = 82
B. x= 45/4
C. x= - 45/4
D. x= -82
Answer:
B. x=45/4

Lucy wants to decorate the curved surface of a trash can that has a radius of 4 in. and a height of 12 in.
What is the area of the curved surface of the trash can she will need to decorate?
A trash can with radius 4 inches and height 12 inches.
12 in =30 cm
4 in = 10 cm
area of 1 circle= 3.14×10×10= 314 cm²
area of 2 circle= 314×2= 628 cm²
if u unfold the trash can the biggest surface(not the circle) will become a rectangle with two circles(628 cm²)
length of rectangle = circle circumference
= 2×3.14×10
=62.8 cm
area of rectangle= 62.8 × 30 = 1884 cm²
total area= 1884 + 628 = 2512 cm²
Answer:
2512 cm²

there is 10 fishes in a tank.
1 dies
3 swim away
4 choke on water
2 are breathing
how many fish are in the tank ?
10
It doesn't say they jumped out of the tank.
Answer:
Im not quite sure but I think it is either 10, cause it says there are 10 fish in the tank. Either that or 8 (ill explain)
Step-by-step explanation:
1 died, but that doesnt mean it was taken out of the tank. 3 swam away, but if they are in a tank they probably just swam to a different part of the tank. 4 choke on water, but that doesnt mean they didnt recover. however, the "2 are breathing" part got me confused since the definition of breathing means taking in air and expelling stuff out...fish "breathe" water so it didnt make sense. So, if you include the 2 breathing fish there are 10, but if u dont there are 8.
I really hope this helps :)
The total cost of renting a cement mixer is given by the graph below.
The total cost of renting a forklift is given by the equation y = 30x + 30.
Which item has a higher initial/starting fee that must be paid no matter how many days it is rented for in order to rent it?
Answer:
The cement mixer
Step-by-step explanation:
When x is 0 for the cement mixer, y is 40,
While when x is 0 for the forklift, y is only 40
4x + 60 + 5x = 100
What is x?
Answer:
50 pointssssssssssssssssssssss
Answer:
x = 40/9
Step-by-step explanation:
4x + 60 + 5x = 100
=> 60 + 9x = 100
=> 9x = 40
=> x = 40/9

Consider the points (-5,2) and (3,-9)
What's the horizontal distance between the two points?
Answer:
The distance between the 2 points is about 13.6
Step-by-step explanation:
Picture the 2 points on a graph, and then look at the distance between them as the hypotenuse of a right triangle. You can easily find the length of the legs of that triangle, and with those legs, you can use the pythagorean theorem to calculate the length between the points.
The length of one leg is the distance between the 2 x-coordinates, between -5 and 3, so that's 8.
[tex]3--5=3+5=8[/tex]
The length of the other leg is the distance between the y, between 2 and -9.
[tex]-9-2=-11[/tex]
That's just a distance of 11, as there's no such thing as negative distance.
Now we have the legs, so we can find the hypotenuse:
[tex]a^2+b^2=c^2\\8^2+11^2=c^2\\64+121=c^2\\c^2=185\\c\approx13.6[/tex]

The base of a triangular prism is a right triangle with a base of 20 feet and a height of 120 inches. The height of the prism is 5 feet.
What is the volume of the prism, in cubic feet?
Enter your answer as a number, like this: 42
Do not enter units.
HELPPPP PLEASEEEEE
Answer:
The volume in Cubic feet is 60 cft.
Step-by-step explanation:
we have to divide 20 by 120. 120 ÷ 20 = 60. Even though 5 is divisible by 60, we won't be doing that. 60 cft. is the answer.
Hope this helps!
Answer:
it is 500 cubic feet, when it is a triangle or triangular prism we divide it in half since its half a square, 120 inches=10 feet. 10ftx20x1/2=100. 100x5=500
