Answer:
170
Step-by-step explanation:
1. change 15% to decimal - 0.15
2. multiply it by the regular price ($200) - 0.15 x 200 = 30
3. subtract the regular price by the discounted price - 200 - 30 = 170
I really hope this helps :)

PLEASE HELP ME WITH MY ANGLE PAIRS...If you help i will give your 5 stars, a thanks, and a brainliest :)
Answer:
x = 15
Step-by-step explanation:
9x - 5 = 7x + 25 ......(vertical angle and corresponding angle )
9x - 7x = 25 + 5
2x = 30
x = 30 / 2
x = 15
Last year Ron bought 40 pen sets and sold 25. This year he bought 75 pen sets and sold 60. The absolute error each year was the same. Are the percent errors also the same? Explain using the solutions.
Answer:200
Step-by-step explanation:
Answer:
No, differentStep-by-step explanation:
Last yearBought 40 sets
Sold 25 sets
Error = 25 - 40 = -15Absolute error = | - 15| = 15Percent error = 15/40*100% = 37.5%This yearBought 75 sets
Sold 60 sets
Error = 60 - 75 = -15Absolute error = |-15| = 15Percent error = 15/75*100% = 20%We can see absolute errors are same but percent errors are different.
The reason is the referenced numbers are different.

25=2y - 15 solve y AND SIMPLIFY HELP ME PLEASEE
Answer:
y=20
Step-by-step explanation:
25+15=40
2y=40
40/2=20
y=20
Answer:
y = 20
Step-by-step explanation:
25=2y - 15
2y - 15 = 25
2y - 15 + 15 = 25 + 15
2y = 40
2y ÷ 2 = 40 ÷ 2
y = 20
__________________________
2y - 15 = 25
2(20) - 15 = 25
40 - 15 = 25
25 = 25

Please answer!! What's the slope?
Answer:
B.) undefined
Step-by-step explanation:
It is a vertical line therefore is undefined because
a horizontial line is a line with zero slopea diagnal line from the left bottom to the right top { / } is a line with a positive slopea diagonal line from the left top to the right bottom { \ } is a line with a Negitive slope.Matthew has lived in NY for 10 years. Matthew earns $17.25 per
hour. He worked 5.8 hours on Friday, 4.5 hours on Saturday, and 8
hours on Sunday. How much money did Matthew earn in all on Friday,
Saturday, and Sunday?
Answer:18.3
Step-by-step explanation: 18.3 because 5.8 + 4.5 =10.3 then add 8 its 18.3
Answer:
$315.68
Step-by-step explanation:
We would first add up all of the hours, so that would be 5.8+4.5+8 to get 18.3 hours. Since it is saying $17.25 per hour we would multiply 17.25 and 18.3 to get 315.675. But, because we are dealing with money, our answer would be rounded to the nearest hundredth. So, Mathew earned $315.68 on Friday, Saturday, and Sunday altogether.

Taylor had $60 dollars to buy a new pair of sneakers. He saw a pair he really liked that originally cost $72 but were on sale for 15% off. Does Taylor have enough money to buy them on sale?
Answer:
No.
Step-by-step explanation:
72 times 0.15=10.8
72-10.8=61.2
No. Taylor doesn't have enough.
You could also have done 72 times 0.85, and then you wouldn't have had to minus 10.8 and all those stuff.
Hope this helps!

Answer two questions about Equations A and B:
A. [tex]\frac{x}{4}[/tex] + 1 = -3
B. x + 4 = -12
1) How can we get Equation B from equation A?
Choose 1 answer:
A
Rewrite one side (or both) using the distributive property
B
Rewrite one side (or both) by combining like terms
C
Multiply/divide only one side by a non-zero constant
D
Multiply/divide both sides by the same non-zero constant
2) Based on the previous answer, are the equations equivalent? In other words, do they have the same solution?
a: yes
b: no
Write in exponential form
8= ?
Answer: 2.08
Step-by-step explanation:
g÷ 5/8 =1
basically its asking what divided by 5/8 = 1
Answer:
5/8 divided by 5/8 = 1
Step-by-step explanation:
First, you know that dividing by a fraction is the same as multiplying by its reciprocal, so dividing by 5/8 is the same as multiplying by 8/5.
[tex]g / 5/8 = 1\\g * 8/5 = 1[/tex]
Now, multiply both sides by 5 to get rid of the fraction.
[tex]8g = 5[/tex]
divide both sides by 8
[tex]g = 5/8[/tex]

If the equation is 0=0.64z-z+0.36z and the answer is true for all z what are 2 values to check the solution
Example of what I mean...
Answer:
You can choose trivial values such as [tex]z=0[/tex], but also something like [tex]z=69[/tex] if you feel more daring. Both equations will come out to yield [tex]0=0[/tex], which is obviously true.
Step-by-step explanation:
Because the answer is true for all [tex]z[/tex], any two values can be chosen. It is most often useful to choose easy values of [tex]z[/tex] for these kinds of situations, though.

x : 6 = 10 : 150
Answer:
its is 90
Step-by-step explanation:
6x10=60 150-60=90
Answer:
0.4 or 2/5???
Step-by-step explanation:
I believe this is a proportion/ratio problem.
Think of it like this:
x/6 = 10/150
To solve for x, you must cross multiply:
150x = 6*10 (150x... DON'T write 150*x, that is nonsense)
150x = 60
x = 60/150 (you divide because you are actually dividing 150 on both sides and doing the opposite operation of multiplication)
x = 6/15
x = 2/5 or 0.4 (I simplified it)
Hopefully this helped? I can't seem to find a whole number answer... so the only options I could do are 2/5 or 0.4
