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:
To find the slope of the given line, slope is the rise divided by the run of a line.
Slope =
Picking points (4, 18) and (8, 12)
Now;
x₁ = 4
y₁ = 18
x₂ = 8
y₂ = 12
Slope =
=
= 
These numbers are "a" and "b".
Sum is 64, so
a+b=64
Difference is 42 so
a-b=42
So you've got:

When a+b=64 and a=53 you've got:
53+b=64
b=11
So these numbers is 53 and 11.
H= 4 because volume of a prism is V=Bh and V=96 and B = 24 so it would be left as 96=24h
So in order to find h we have to divide 24 by each number to find h alone so 24 divided by 24 equals 0 and 96 divided by 24 equals 4 so your answer is 4. Also, if you put the equation together after you find 4 you will see it all adds up. 96=24(4) which is correct
