Answer:
13 units
Step-by-step explanation:
It's literally a number line, you can count each mark if you have to or just do 7+6
Ummm there’s no right triangular
I’m guessing red at this point-
Answer:
9/16
Step-by-step explanation:
Solve for x over the real numbers:
2 x^2 + 3 x - 3 = 0
Divide both sides by 2:
x^2 + (3 x)/2 - 3/2 = 0
Add 3/2 to both sides:
x^2 + (3 x)/2 = 3/2
Add 9/16 to both sides:
x^2 + (3 x)/2 + 9/16 = 33/16
Write the left hand side as a square:
(x + 3/4)^2 = 33/16
Take the square root of both sides:
x + 3/4 = sqrt(33)/4 or x + 3/4 = -sqrt(33)/4
Subtract 3/4 from both sides:
x = sqrt(33)/4 - 3/4 or x + 3/4 = -sqrt(33)/4
Subtract 3/4 from both sides:
Answer: x = sqrt(33)/4 - 3/4 or x = -3/4 - sqrt(33)/4
Answer: Jim had $28 , Kirk had $16
Step-by-step explanation:
Let's represent the amount of money they had initially as k and j respectively.
From the first statement, Kirk has 12 dollars less than Jim. Mathematically, this could be expressed as :
K + 12 = J or K = J - 12
From the second sentence, we can deduce the following : If Jim's initial amount is halved, Kirk would be 2 dollars richer. This could he expressed mathematically as ;
J/2 = K - 2
NOW , let's solve both equations simultaneously.
K = J - 12 ..........(i)
J/2 = K - 2 ........(ii)
Let's substitute for k in equation ii using equation I
J/2 = J - 12 - 2
J/2 = J - 14
J = 2J - 28
Rearranging yields
2J - J = 28
J = 28
Since K = J - 12, that means k = 28 - 12 = 16
Hence initially, Jim had $28 while Kirk had $16
