Answer:

3. B

10. X≤3

7. x>-15

9. Step 2

Step-by-step explanation:

7. -X+5<20

-X+5-5<20-5

-X/-1<15/-1

X<-15

9. Kahal made a mistake in the 2nd step because he should have done to opposite of subtraction which is addition. so instead or subtracting 4 from both sides he should have added 4 to both.

I know you are not going to mark me brainliest because you said the other person will but personally you should not make that decision based of of that it should be best answer but anyway hope this helps

Factor 60y-90-20x to identify the equivalent expressions. Choose two answers.

pochemuha

C & D
Step-by-step explanation:
One evident common factor between 60, 90, & 20 is 10 because all these numbers end in a 0; Therefore one way to factor the equation 60y - 90 - 20x is;
10 (6y – 9 – 2x)
5 is also a common factor between the numbers 60, 90, & 20
60/5 = 12; 90/5 = 18; 20/5 = 4
Therefore 60y - 90 - 20x is also equal to;
5 (12y – 18 – 4x)

Gabriel interviewed his 30 classmates on whether or not they own a bike and live near a pool. He displayed his results in the tw

snow_tiger [21]

Answer:

The true statement is:

A) Over half of the bike owners live near a pool.

Step-by-step explanation:

See the attached table

According to the data of the table, we will check which statement is true.

A) Over half of the bike owners live near a pool.

The number of the bike owners = 8 + 7 = 15

The bike owners live near a pool = 8

The percentage of the bike owners live near a pool to all the bike owners= 8/15 = 0.533 > 0.5

The statement is true.

B) Less than 55% of his classmates live near a pool.

The number of classmates = 30

The number of classmates live near a pool = 8 + 10 = 18

The number of classmates live near a pool to all

classmates = 18/30 = 0.6 = 60% > 55%

The statement is wrong.

C) About 50% of his classmates don't live near a pool.

Don't live near a pool = live near a pool

So, the same explanation of statement B

The statement is wrong.

D) 2/3 of his classmates that live near a pool don't own a bike.

The number of classmates live near a pool = 8 + 10 = 18

The number of classmates live near a pool and don't own a bike = 10

The percentage of classmates live near a pool and don't own a bike to classmates live near a pool = 10/18 = 0.556 < 2/3

The statement is wrong.

A parallelogram has vertices E(1, 4), F(5, 3), G(−3, 1), and H(1, 0). What are the coordinates of the midpoint of each diagonal?

kozerog [31]

Check the picture below.

now, the diagonals cut each other in two equal halves, thus, the midpoint of GF is the same coordinates as the midpoint for EH, so let's check what the midpoint for GF is then

$\bf \textit{middle point of 2 points }\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
G&({{ -3}}\quad ,&{{ 1}})\quad 
% (c,d)
F&({{ 5}}\quad ,&{{ 3}})
\end{array}\qquad
% coordinates of midpoint 
\left(\cfrac{{{ x_2}} + {{ x_1}}}{2}\quad ,\quad \cfrac{{{ y_2}} + {{ y_1}}}{2} \right)
\\\\\\
\left(\cfrac{5-3}{2}~~,~~\cfrac{5-1}{2} \right)\implies \left( \cfrac{2}{2}~~,~~\cfrac{4}{2} \right)\implies (1,2)$

Math question down below

Kipish [7]

Answer: 6928

----------------------------------------------------------

Explanation:

We have two areas we need to find: The area of the trapezoid and the area of the rectangle. Let's call these areas A1 and A2.

Area of Trapezoid = (height)*(base1+base2)/2
A1 = h*(b1+b2)/2
A1 = 80*(150+100)/2
A1 = 80*250/2
A1 = 20000
A1 = 10000

Area of Rectangle = (length)*(width)
A2 = L*W
A2 = 48*64
A2 = 3072

Subtract the two areas (A1-A2) to get the difference D
D = A1 - A2
D = 10000 - 3072
D = 6928

This difference D is exactly equal to the shaded area.
