Mr. Williams physical education class lasts for 7/8 hour. How many minutes are spend warming up and cooling down if both of these total 3/10?How many minutes are NOT spend on instruction, if this total is 8/10?? Thanks.
it is same because if u see there is 0 behind 0.6 but u can't see it so it is equal
It is the same. Even though you put a 0 in the end can't change the number
What is the value of x?1. 6( -3 - x) - 2x = 14 x=
2. 2/7x + 6 + 17x = 18 x=
Answers
1) expand the brackets 6(-3 - x) - 2x = 14 -18 - 6x - 2x = 14 simplify -18 - 8x = 14 then add 18 to both sides to get the x's on there own -8x = 32 then divide by -8 x = 32/-8 x = -4
2) multiply everything by 7x 2 + (6 x 7x) + ( 17x × 7x) = 18 x 7x 2 + 42x + 119x^2 = 126x put everything on one side 119x^2 - 84x + 2 = 0 then use quadratic equation to solve
x = 0.024671849 or 0.6812105039
I don't get # 2 please help and fast

I wouldn't say that. It looks to me like you've absolutely got it ... almost.
A). Your fraction is correct. But it's not in simplest form like they want it. Reduce 18/45 to simplest form. Hint: Divide top and bottom by 9 .
B). They want the percentage that's the same as 18/45 . Do you remember how to change a fraction to percent ? A fraction is just a short way to say "division". " 18/45 " means " 18 divided by 45 ". Do the division. To change the quotient into percent, multiply it by 100 . (Same as moving the decimal point 2 places to the right.) Round it the nearest whole number, if it isn't already a whole number.
C). Again, your fraction is correct, but it isn't in simplest form. Reduce 27/45 to simplest form. Hint: Divide top and bottom by 9 again.
D). Change this fraction to percent, just like you did for the female fraction. (Do the division that the fraction says, and multiply the quotient by 100.) (Round to the nearest whole number percent if it isn't already.)
You already did the technical stuff. I just added some mechanical things.
Lisa's store collects 5% sales tax on every item sold. If she collected $22.00 in sales tax, what was the cost of the item her store sold?
Answers
5% of sold is tax 22.00=tax therefor 22.00=5% of total
5%=5/100=1/20 'of' means multiply 22.00=1/20 times totl multiply both sides by 20/1 to clear fraction 440.00=total
cost of items is $440.00
22/0.05 = 440 therefore the cost of the item was $440
(5% of 440 = 22)
Andrew's recipe requires 7 pieces of toast every 14 spoons of butter.how many pieces of toast will he need if he uses 22 spoons of butter?
Answers
Since 7 is half of 14, Andrew would need 11 pieces of toast for 22 spoons of butter because half of 22 is 11.
