2(4k+8)=10
8k+16=10 (she said 2k instead of 8k)
To continue solving, subtract 16 from both sides. That would give you 8k= -6. Then divide both sides by 8, and get -6/8 which equals -3/4.
Answer:
He made approximately 32 free throws.
Step-by-step explanation:
Assuming that there's a typo in the question and that he made 57% of his attempted free throws, then we can solve it as shown below:
We can apply a rule of three in order to calculate the number of free throws he made. This is done as follows:
56 free throws -> 100%
x free throws -> 57%
56/x = 100/57
100*x = 57*56
x = 57*56/100 = 31.92
It can also be solved by transforming the percentage in a fraction such as 57% = 57/100 and then multiplying it by the total attempts.
free throws made = 56*57/100 = 31.92
He made approximately 32 free throws.
The unit rate for $240 per 4 days is $60 per 1 day.
To get a unit rate you must simplify the rate down to $X per 1 day.
To get 4 days down to 1 day you must divide 4 by 4.
Doing the same to the other side you divide 240 by 4.
So now you have $60 per 1 day.
Answer:
1 hour later , 21 pages read
Step-by-step explanation:
x hour later they will read the same number of pages
Tori: 16 + 5x
cora: 13 + 8x
16 + 5x = 13 + 8x
minus 5x each sides: 16 = 13 + 3x
minus 13 each sides: 3 = 3x
divide 3 each sides: x = 1
1 hour later both of them will read 16 + 5 x 1 = 21 pages
check cora: 13 + 8 x 1 = 21
