The appetizer can be any one of 6 choices. For each of those ...
The rice can be any one of 4 choices.

Total number of possible combinations is (12 x 6 x 4) = 288 .

there is 27 meals cause if you have 12 entrees and 6 appetizers you still have 12 so 2*6=12 so 2*12=24 and how many times can 4 go into 12 and that is 3 so 24+3=27

the answer is 27

an easy way to do it is subtituet (-7,5) and (-4,1) into the equations and find out which ones check. remember (x,y)

so A
if we try (-7,5)
5-7=-3/4(-7+5)
we can immediately see that -2 is not equal to -3/4(-2)
so A is wrong

B
if we try (-7,5)
5-5=-4/3(-7+7)
0=-4/3(0)
0=0
so B is correct

C
if we try (-7,5)
5+4=-3/4(-7+1)
9=-3/4(-6)
9 is not equal to 18/4
so C is wrong

D
if we try (-7,5)
5-1=-4/3(-7+4)
4=-4/3(-3)
4=12/3
4=4
D is correct

If you wanted to try the second point (-4,1) in B and D
B
1-5=-4/3(-4+7)
-4=-4/3(3)
-4=-12/3
4=4
B is still correct

D
1-1=-4/3(-4+4)
0=-4/3(0)
0=0
D is still correct

so the answers are B and D

What is 52 over 50 equals to in percent

Answers

Hey there!

Here are the steps involved in answering this question:

1. Write 52 out of 50 as a fraction which is $(52)/(50)$

2. Turn the fraction into a decimal. To do this, divide the numerator by the denominator. The numerator is the top part of the fraction while the denominator is the bottom part of the fraction.

$(52)/(50)$ = 1.04

3. You get 1.04. Now, turn this into a percent. Move the decimal, 2 places to the right or just multiply the decimal by 100.

1.04 = 104%

The final answer is 104%.

Another way of doing this is to get 100 as a denominator.
Since, percent means, "Out of 100", we have to make the denominator 100.

1. $(52)/(50)$ = 104/100

Just multiply each side by 2.

Again, the final answer is, 104%

52/50 is equal to 104%
52÷50=1.04
1.04*100=104%
