Answer:
38
Step-by-step explanation:
Since 19 is 50% of x, we multiply it by two
19 x 2 = 38
12x^5 − 15x^3 + 30x^2 If this isn’t the right answer i’m very sorry
Answer:
12750
Step-by-step explanation:
Sum = 50 ( 1 - 2^8 ) / ( 1 - 2) = 12750 visitors in the first 8 weeks
Answer:
Length = 25 inches and width = 15 inches.
Step-by-step explanation:
Let us assume that the length of the rectangle is L inches and the width of the rectangle is W inches.
Now, the area of the rectangle is A = LW = 375 sq. inches ........... (1)
Now, given that the length to width ratio of the rectangle is 5 : 3.
Let L = 5x and W = 3x, then from equation (1) we get,
(5x)(3x) = 375
⇒ 15x² = 375
⇒ x² = 25
⇒ x = 5 {Neglecting the negative root, as length can not be negative}
Now, Length = L = 5x = 25 inches and Width = W = 3x = 15 inches. (Answer)
Hey there!
Let's create a systems of equations using x and y.
4x+3y=15
3x-2y=7
We need to solve this using elimination. First, we need to multiply the first equation by 2/3 so that we can cancel out the y's when combining our equations.
2 2/3x+2y=10
3x-2y=7
Now we combine the equations...
5 2/3x=17
x=3
Now we can plug our x into the first equation to find y.
12+3y=15
y=1
Our numbers are 3 and 1.
I hope this helps!
