7y - 3x = -5
-3x = -7y - 5
x = 7/3y + 5/3
Answer:
10x3000
Step-by-step explanation:
Answer:
50 total penguins
Step-by-step explanation:
In the following example x = the total number of penguins.
Set it up as follows.
15 over x = 30 over 100
Cross multiply the numbers. (30 times x) and (15 times 100)
This results in 30x = 1500.
Divide both sides by 30 which results in x = 50.
This means that there is a total of 50 penguins.
In the following example x = the number of Emperor penguins.
If you would like to double check this, set up as follows.
x over 50 = 30 over 100
Cross multiply the numbers. (30 times 50) (100 times x)
This results in 100x = 1500.
Divide both sides by 100 which results in x =1 5.
This means that there are 15 Emperor penguins.
The answer is D
Explanation
.50x4=2
In a coordinate point, the values would go (x,y). Substitute the x and y values from the coordinate points into the equation given.
8(3)+B(4)=40
Multiply 8x3
24+B(4)=40
Subtract 24 from both sides
4B=16
Divide the whole equation by 4
B=4
