Answer:
3(16x+9)/4
make sure it's a fraction
Answer:
27 11/4x
Step-by-step explanation:
First we add the similar parts of the expression.
Whole numbers
6 + 9 + 5 + 7 = 27
Then we add the fractions that dont have x.
We only add the numerators (2 and 3) and dont change the denominators (4)
2/4 + 3/4 = 5/4
Now we add the ones with x.
5/4 + 3/4x + 3/4x = 11/4x
Now we combine those parts together, making
27 11/4x
sorry if Im wrong

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
Hi could someone please help me
Answer: y = -1/4x - 6
Step-by-step explanation: the slope is -1/4 because slope = rise/run, the rise is 1, and the run is 4 and the slope is negative. the y intercept is -6 because it passes through -6 at the y axis.
Answer:
-1/4x + -6
Step-by-step explanation:
The slope is -1/4 because slope = [tex]\frac{rise}{run}[/tex],
So:
-[tex]\frac{1}{4}[/tex] is the slope, also is negative.
The y intercept is -6 because it passes through -6 at the y axis.
( I also checked it on khan Academy and it was correct)
Hope this helps :)

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.

On a math assignment Audrey was asked to draw a regular polygon. The image below shows the shape that she drew.
What could you do to determine if Audrey’s shape is a regular polygon?
Answer:
According to Wolfram, "sided polygon in which the sides are all the same length and are symmetrically placed about a common center."
According to TheSchoolRun, "A polygon is a flat, two-dimensional (2D) shape with straight sides that is fully closed (all the sides are joined up). The sides must be straight. Polygons may have any number of sides. A polygon. A shape with curved sides is not a polygon."
So, yes, that is indeed a polygon.
Answer:
Audrey's shape is not a regular polygon.
Step-by-step explanation:
We know what a polygon is, but there are two types. Regular and irregular. A regular polygon's sides are all equal. An irregular polygon's sides are not all equal.
In this case, Audrey's shape is an irregular polygon. 3 of the lines are of unequal length to the rest which makes it irregular.

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)

Answer:
7x + 96 = 180
Step-by-step explanation:
We are given that the right side of the equation should be 180 because that is equal to the sum of the triangle's interior angle measures.
We can solve for the left side by adding the triangle's interior angle measures.
(2x + 1) + (5x + 5) + 90
Remember that a right angle is 90°.
All we need to do from here is combine like terms:
= (2x + 5x) + (1 + 5 + 90)
= 7x + 96
So, the equation that represents the model is:
7x + 96 = 180
Answer:
C) 7x + 96° = 180
Step-by-step explanation:
their is one right angle and 2 equations. The sum of the interior angle is 180
90° + 2x + 1 + 5x + 5 = 180
Combine like terms
90 + 1 + 5 = 96
2x + 5x = 7x
7x + 96° = 180
simplify
10m + – 8 + 9m + – 10m
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

Answer: 1
Identify the point on the axis where x = -9, and find the correlating portion of the function above or below that axis. In this case, the function is equal to 1 when x is equal to -9.
Answer:
y= 1
Step-by-step explanation:
You simply need to look at the graph. When we look at the x-axis and look at -9, the line graphed (y-axis) is at 1. So point (-9,1) shows us our answer!
Look at my image below for more help!

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.
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)

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
