Which fraction is not equivalent to 16/24 A. 2/3 B. 5/8 C. 32/48 D. 4/6

Answers

b) 5/8
because:
2/3 x 8 = 16/24
32/48 divided by 2 = 16/24
4/6 x 4 = 16/24
so b) 5/8 it is

5/8 because
If you divide 16 by 8 then you get 2 and if you divide 24 by 8 you get 3 this equals=2/3
32/48- If you multiply 16 by 2 you get 32, if you multiply 24 by 2 you get 48 which gives you an answer to 32/48
4/6- If you divide 16 by 4 you get an answer of 4, if you divide 24 by 4 you get an answer of 6, which gives you an answer of 4/6

How do you answer these questions?

Answers

First page:

Angles B and C >>> vertical angles

C + D is 180 because they form a >>> straight line

D and E are congruent bc they are alternating interior.

Second page:

If A = 72 degrees, then D is 72 degrees. E and G would also be 72 degrees.

If A = 72, just remember that A + B = 180 (bc together they are a straight line), so 180-72 = 108. So Angle B is 108 degrees.

If B is 108 degrees, then C, F and H are also 108 degrees.

So the actual questions in the order listed:

B = 108 degrees

D = 72 degrees

E = 72 degrees

F = 108 degrees

H = 108 degrees

G = 72 degrees

2. How many solutions does this system have? 2x + y = 3, 6x = 9 – 3yA) 1
B) None
C) Infinite
D) 2

Answers

Answer:

The system of equation has infinite solution.

C is correct.

Step-by-step explanation:

We are given system of equation

2x + y = 3

6x = 9 – 3y

First we re-write the second equation in standard form

So, we add 3y both sides

6x+3y=9 ---------------- (2)

2x+y = 3----------------- (1)

Multiply equation 1 by 3

3(2x)+3y = 3(3)

6x+3y=9

Subtract new equation from 2nd equation

6x-6x + 3y-3y = 9-9

0=0

LHS=RHS

This is true statement. If statement is true then infinite number of many solution.

Hence, The system of equation has infinite solution.

2x + y = 3
6x = 9 - 3y
↓
2x + y = 3
6x + 3y = 9

3(2x + y = 3)
3(2x) + 3(y) = 3(3)
6x + 3y = 9

There is an infinite number of solutions in the system (the answer is C).

Graph the line using intercepts: 4x-3y=12

Answers

First you have to find the intercepts!

To find the y-intercept (I usually do that first), pretend x=0.
Then it becomes:
4(0)-3y=12
Which then becomes:
-3y=12.
Divide both sides, and y = -4.
Then the (x,y) coordinate would become (0, -4).

Next you would find the x-intercept, and pretend y = 0.
Which then becomes:
4x-3(0)=12
3x0 cancels out to become:
4x = 12
And x = 3 because division stuffs.
Then THIS point would then be (3,0).

So then, you would plot (0,-4) and (3,0) on a graph and connect the points! I attached a picture for reference.

hope that helped~

Graph the intercepts by assigning the balue to y or x then after u assign u will graph it. Since it is a linear equation it might be easier so it may be a line not a parabola
