Answer:
a = $17.25
Step-by-step explanation:
let the money spend on the necklace be a
we have
15.75 +1.5*2 +a + 14 = 50
-> a = 50 -15.75 -3-14
-> a = $17.25
Answer:

Step-by-step explanation:
Use the distributive property of equality to multiply and get:

Simplify by combining like terms to get your end result:

Answer:
MN = 4
Step-by-step explanation:
Given that L, M, N are collinear,
LN = 9,
MN = 4x
LM = 5x
Required:
Length of MN
SOLUTION:
To calculate the numerical length of MN, we need to find the value of x.
To find the value of x, generate an equation to solve for x as follows:
(segment addition postulate)
(substitution)
Solve for x

Divide both sides by 9


MN = 4x
plug in the value of x
MN = 4(1) = 4
