Answer:
52=x-15(being vertically opposite angle)
52+15=x
x=67
I'm going to assume that you want to know whether the coordinate satisfies the equation. Let's find out;
-3х - 6у = 17
-3(6) - 6(3) = 17
-18 - 18 = 17
-36 ≠ 17
The point (6, 3) does NOT satisfy the equation.
Best of Luck!
Answer:
a = 18/b²
Step-by-step explanation:
Step 1: Write equation
1/3ab² = 6
Step 2: Solve for <em>a</em>
- Multiply both sides by 3: ab² = 18
- Divide both sides by b²: a = 18/b²
Answer:
1.8 and 14.3
Step-by-step explanation:
Our equation is a quadratic equation so we will use the dicriminant method
- Let Δ be our dicriminant
- a=1
- b= -16
- c= 25
- Δ= (-16)²-4*25*1=156≥0
- so we have two solutions : x and y
- x= (16-
)/2= 1.7555≈ 1.8 - y=(16+)/2=14.244≈ 14.3
Answer:
One has $80 and the other has $480
Step-by-step explanation:
First we look at our total amount of $560, and I solved this by thinking of a logical number that could be multiplied and still add up to this total.
I got to $80 as my answer for the first man because 80 multiplied by 6 is equal to 480 which therefore accounts for the second man
480+80=560, simple
