Answer:
Price of each bracelet = $4.75
Step-by-step explanation:
Given:
y =4.75x
In equation;
y = kx
where k is constant
So , we say that 4.75 is constant of proportionality
So price of each bracelet = $4.75
Answer:
-8 < x < 13
Step-by-step explanation:
|2x-5|<21
The absolute value has 2 solutions, one positive and one negative. When we take the negative solution, we have to flip the inequality.
2x-5 < 21 and 2x-5 > -21
Add 5 to each side
2x-5+5 < 21 +5 2x-5 +5 > -21+5
2x < 26 2x > -16
Divide by 2
2x/2 <26/2 2x>-16/2
x <13 and x>-8
-8 < x < 13
**Remember this rule: the sum of a triangle's angle measurements always = 180
So 2x + 3x + 4x = 180
9x = 180
9x/9 = 180/9
x = 20
A) 20
Answer:
(-5,1)
Step-by-step explanation:
Because the red line (graphical representation of one equation) and the blue line (graphical representation of the other equation) intersect at (-5,1), the solution to the systems of equations is (-5,1).
