Answer:
9m-8
Step-by-step explanation:
you need to group like terms and solve
Answer:
9m - 8
Step-by-step explanation:
We know that,
( - ) × ( - ) = ( + )
( + ) × ( + ) = ( + )
( - ) × ( + ) = ( - )
Accordingly, let us solve it now.
10m + ( – 8 ) + 9m + ( – 10m )
Solve the brackets.
10m - 8 + 9m - 10m
Combine like terms.
9m - 8
please help me i need it.
Answer:
answer is 3/5
Step-by-step explanation:
Hi, This is Part B to the previos question i was offering 50 points for, Im now offering 30 points for this question. I need an answer and explanation please.
Part A ending answer: 3 cups.
1/4 of a gallon=4 cups
If I understand this correctly, there was a total of 7 cups before it was poured, adding the original answer to this one.
7 cups would equal .43 gallons, a bit less than half a gallon. If that's so, then .43 would equal 43 percent, and 43% of 128 fluid ounces would be 55.04 fluid ounces. Now the further solution, with more numbers past the decimal, it would be equal to approximately 56.
Therefore, my answer, if I understood correctly, would be 56.
Help please, I need to get 5 percent in khan and I don't understand this problem
Hello there!
First things first, place the 2 on the y-axis. 2 is your "y" intercept.
Rule of thumb: if there is a constant(single number) alone and without any variable next to it, it's going to be your y-intercept.
Next we need to count up three units from the y-intercept and over four units.
Overall:
The 2 should be plotted on the y-axis.
The new coordinate should be (5,4)
Round to the nearest ten, then estimate the product. 82 x 78 = ___

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143
(7th)Math question someone pls explain how to answer it I am stuck pt.7
Answer:
x < 4
Graph: open dot on 4 and arrow pointing left.
Step-by-step explanation:
x + 5 < 9
Subtract 5 from both sides.
x < 4
You solved the inequality correctly.
To graph it, place an open dot on 4 and an arrow going left.
Answer:
The answer is an open circle to the left
Step-by-step explanation:
Closed circle means atleast and open means more or less than. THe equation is that 4 is more than a number. So that means it will go to the left and the circle would be open because it doesn't say at least, it's just <.
I hope this helps, I'm kind of bad at explaining.
If you have any questions please ask me! :)

Answer: The probability of not choosing a black shirt is 8/10 or 80%.
Step-by-step explanation: You add up the number of total shirts and then subtract the number of black shirts.
Answer:
20% probability of not choosing the black shirt
Step-by-step explanation:
There are 10 shirts on the shelves. Each has a 10% chance of not being chosen. There are 2 black shirts which have 10% chance each of not being chosen. if you sum it up ( 10% ×2) you will get a 20% probability of the black not being chosen.
Therefore there is a 20% probability of not choosing the black shirt
Triangle JKL was dilated with the origin as the center of dilation to create triangle J'K'L'. The triangle was dilated using a scale factor of 1/2. The coordinates of the vertices of triangle JKL are given. You can use the scale factor to find the coordinates of the dilated image. Enter the coordinates of the vertices of triangle J'K'L' below.
(Decimal values may be used.)
Answer:
J' (-2, 2.5), K' (1, 2.5) L' (1, -2.75)
Step-by-step explanation:
With a scale factor of 1/2=.5 you can simply multiply all coordinates by .5 (or divide by 2)
J (-4,5) x 1/2= (-2, 2.5)
K (2,5) x . 5 = (1, 2.5)
L (2, -5.5) /2= (1, 2.75)
