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

Hi I need help with this problem. But it has to be shown with work. Does anyone know?
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
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

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.

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.

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!
