what is thisssssssss
Answer:
it is a game
Step-by-step explanation:
solve for a and B. A. a=400/21, b = 580/21 B. a=400/21, b=20/21. C a=580/21, b=20/21. D a=20/21, b=580/21
Answer:
Step-by-step explanation:
21/29 = 20/b
b = 20*29/21 = 580/21
a^2 + 20^2 = (580/21)^2
a = 400/21

PLEASE HELP ME WITH MATH (also please tell me how you got the answer so I understand)
Answer:
1st=3x+9, 2nd=8x, 3rd=4x+3y, 4th=neither, 5th=neither, 6th=4x+3y, 7th=3x+9, 8th=8x.
Step-by-step explanation:
for the 1st one cancel out the y's, 3x+9. for the 2nd one: 2x-1x+7x, (2-1+7)x, 8x. for the 3rd one: 2x+2y+2x+y, 4x+2y+y, 4x+3y. for the 4th one: 7x+x+0-y, 8x-y. for the 5th one: 2x+2y+2x, 4x+2y. for the 6th one: 4x+4y-y, 4x+3y. for the 7th one: 2x+6+x+3, 3x+6+3, 3x+9. for the 8th one: 5(2x)-2x, 5 * 2x-2x, 10x-2x, 8x.
Answer:
The answers would be :
first table (equivalent to 8x ) = 2x-x+7x , 7x+x+0×y , 5(2x)-2x
second one (equivalent to 4x+3y) = 2x+2y+2x+y , 4x+4y-y
third one = every expression left but 2x+2y+2x .
you have to calculate them ! for example look at the first one ----> y+3x-y+9 is equivalent to 3x+9 'cause y-y = 0 ,so 3x +9 will be the left expression and you can't calculate it because the both left items in expression are not from the same type , one of them has a x but the other one doesn't have .
or for example the second one is 2x-x+7x and you know that -x can be written as -1x ,so it becomes like 2x+-1x+7x = 8x .
in the above example we could calculate numbers 'cause all of them have the same variable .
hope it was kinda helpful , sorry for bad english :D
ask me if you have further questions .

Two trains started moving at the same time, train A from Boston to New York, and train B from New York to Boston. The distance between the train stations in New York and Boston is 240 miles. The average speed of train A is 60 mph, which is 3 4 of the average speed of train B.
1. How soon will the trains meet
2. How far from New York will the trains meet?
Answer:
------
Step-by-step explanation:
1. The average speed of train A = 60 mph,
The average speed of train B = 60 / 3/4 = 80 mph
Time it takes for trains to meet = 240/(60 + 80) = 240/140 = 12/7 hours
2. The trains meet in 12/7 hours, each traveling at their own speed.
S = D/T, D = S*T
Therefore we can say:
12/7(60) = distance train A is from Boston = 720/7 miles
12/7(80) = distance train B is from New York = 960/7 miles
The distance from New York would = 960/7 miles

The temperature of chicken soup is 192.7°F. As it cools, the temperature of the soup decreases 2.3°F per minute. What is the temperature in degrees Fahrenheit of the soup after 25 minutes?
Answer: 135.2 °F
Step-by-step explanation:
The temperature decreases at a rate of 2.3 °F per minute.
This means that in 25 minutes, the temperature would have reduced by:
= 2.3 * 25
= 57.5°F
If the original temperature was 192.7 °F, the temperature after 25 minutes will be:
= 192.7 - 57.5
= 135.2 °F
I need a quick update on wat we've been learning in 8th grade
A rational number that lies between -2/3 and 5/12
1 Factor the polynomial over the set of real numbers. (a) f(x) = 25x^2 - 10x - 24
Answer:
(5x+4)(5x-6)
Step-by-step explanation:
[tex]25x^{2} -10x-24[/tex]
Separate into two parts, first realizing that the only two factor pairs for 25 are 5 and 5 or 1 and 25. Using 5 and 5 makes the most sense, so
(5x )(5x )
The other two numbers need to multiply to -24 and add up to -10.
Pairs that muliply to 24 could be 1 and 24, 2 and 12, 3 and 8, and 4 and 6. The more you factor the easier it will be to quickly discern which numbers to use. In this case, the right pair is 4 and 6. Because it needs to add up to -10, it should be 4 and -6 (because multiplying out, -30 + 20 = -10).
Thus, the final factored equation is (5x+4)(5x-6). You can check this by FOILing and making sure you get the original equation.
What do I do in this problem?
Answer: p=60
Step-by-step explanation:
Angles on a straight line always add up to 180 degrees.
So, because you have an angle on the straight line with the arrow going up, you have to do:
180-110=70
This will give you the angle inside of the triangle that is next to 110.
Then you would find the angle next to 130 (using the horizontal line) by using the same method so you would do:
180-130=50
This gives you the angle inside the triangle next to 130.
Then because a triangle always adds up to 180 you would add up the 2 angles you have figured out like this:
70+50=120
Then you would take the answer away from 180 like this:
180-120=60
So, p=60
Hope this helps :)

If the area is 1,180 square inches, find the correct values for r, width
and length from the list in your right.
the formula for the area of a rectangle is (length × width) in this case (length × width) = 42
if the length is 7... then what # times 7 = 42? The width has to 6.
to find the perimeter... (2 × length ) + (2 × width) = Perimeter
OR
length + length + width + width = perimeter
7 + 7 + 6 + 6 = ?

9. If AJKL - ANML, find the values of x and y.
Answer:
x = 35, y = 18
Step-by-step explanation:
Since both triangles are similar, their sides must be proportional with means all of them have a common ratio.
If NM = 16, and KJ = 40. 40/16 is the ratio from ∆NML to ∆JKL. The reciprocal(numerator and denominator flip, the product of a number and it's reciprocal is 1) of this is true from ∆JKL to ∆NML.
Now to find the missing sides you multiply a side by the common ratio to find it's corresponding side length.
Dividing by a number is the same as multiplying by the reciprocal of that number.
40/16 can be reduced to 5/2 or 2 ½ as a mixed fraction.
16/40 can be reduced to 2/5 or 0.4 as a decimal.
Since the scale of ∆JKL is greater than ∆NML, you multiply by 5/2 to get the corresponding side of ∆JKL from ∆NML.
Since the scale of ∆NML is less than ∆JKL, you multiply by 2/5 to get the corresponding side of ∆NNL from ∆JKL.
Therefore x = 14 × 5/2 = 70/2 = 35.
y = 45 × 2/5 = 90/5 = 18.
Factor by using the distributive property: 8x - 4y + 20.
a.2(4x - 2y + 10)
b.8(x - y + 12)
c.4xy(2x - 2y + 5)
d.4(2x - y + 5)
All 5 students in Mrs.Awful’s class got 50 for the test For the next test, one of the students got 100 but the remaining students all got 50. What it the average grade in the class now?
Answer:
60
Explanation:
the formula for calculating the average grade would be the total score of all students ÷ the number of students. in this case, that would be:
(100 + 50 + 50 + 50 + 50) ÷ 5
= 300 ÷ 5
= 60
so, the average grade is 60.
