solve each equation for the given variable
xy = k;y
a = 2/b + 3c; c
6(2c = 3d) = 5(4c-3d); d
Step-by-step explanation:
y=k/x
[tex]c = \frac{a - \frac{2}{b} }{3} = \frac{ \frac{ab - 2}{b} }{3} = \frac{3(ab - 2)}{b} = \frac{3ab - 6}{b} [/tex]

In triangle ABC, AB=10, BC=8, and angle B=30. In triangle KLJ, LJ=20, JK=16, and angle L=30. State whether the triangles are similar by choosing the correct postulate or theorem below.
AA
SSS
SAS
Not Similar
Answer:
They are not similar.
Step-by-step explanation:
In triangle ABC, the angle we are given is in between the two defined sides(AB and BC with angle B). If these triangles were similar, we would see this with the SAS postulate.
In triangle KLJ, the angle is not in between the two sides, so they are not similar according to any of these two postulates.

45/.25= 180
For 180 minutes the first option is cheaper
Your welcome
Answer:
180 minutes
Step-by-step explanation:
50-$5 = $45 to spend
$45/$0.25 = 180 minutes

Answer: -5/4
Step-by-step explanation:
It is this because it is a downward slope, and so it has to be negative. The points are 10 at the top and eight at the bottom. But Because the slope goes down to the right, it means that it is going to be negative. So, -10/8 can be simplified down to -5/4 when divided by 2. Hope this helps.

The initial value is also known as the y-intercept, and as you can see on the graph, the y-intercept is 1.
You could also use the formula
y=mx+b, b is the y-intercept, m is slope, y and x are coordinates.
We see one of the coordinates in (-2,0) so x=-2 and y=0
The slope, or rate of change, is 1/2, so m=1/2
Now plug the numbers into the formula:
0=1/2(-2)+b
0=-1+b
1=b

Samantha is buying a chromebook that costs $179.00. The chromebook is on sale for 35% off the original price. How much will the chromebook cost after the discount?
Answer:
$116.35
Step-by-step explanation:
179 x 35/100
= 62.65
This is how much will be taken off of the original price. So we have to subtract that from 179.
179 - 62.65 = 116.35
The new price is $116.35
Answer:
$116.25 after the discount
Step-by-step explanation:
$179 - 35% = x
$179 - $62.25 = $116.75

Which of the following rounds most closely to 1?
A. 1/5
B. 4/5
C. 4/8
D. 2/3
Answer:4/5
Step-by-step explanation:
1/5 is closer to zero than 4/5 so we know it can't we that one.
4/8 is equal to 1/2, and 4/5 is closer to 1 than 1/2 is
2/3 multiplied by 5 is 10/15, while 4/5 multiplied by 3 is 12/15
by getting the same denominator we can see that 4/5 is the closest fraction to zero.
Sarah Jane bought a pair of joggers that were on sale for 40% off the original price. If the original price was $39.00, what was the sales price of the joggers?
The sales price of the joggers is $23.99
________________________________
Discount = Original Price x Discount %/100
Discount = 39.99 × 40/100
Discount = 39.99 x 0.4
________________________________
Final Price = Original Price - Discount
Final Price = 39.99 - 15.996
Final Price = $23.99
