Answer:
9.50 am
Step-by-step explanation:
3.40pm minus 2 hours = 1.40pm
1.40 minus 30 min = 1.10pm
1.10am minus 3 hours = 10.10am
10.10 am minus 20 min = 9.50 am
start at 9.50 .... works for3hrs and 20 min which ends at 1.10... 30min break which ends at 1.40...works for 2hrs that finally ends at 3.40pm
hope this helps☆☆☆
I always had trouble doing percents, but my last algebra teacher taught me an easy way, where you turn the percent into a decimal.
Maria: to find 25% of 26.50, you multiply 26.50 by 0.25 to get 6.625. now, you subtract 6.625 from 26.50 to get 19.875. which would round to 19.88$. To find the 10% sales tax, you multiply 19.88 by 0.10 or 0.1 to get 1.988. that would round to 2.00. She would then add 19.88 and 2.00 to get 21.88$.
Edwin: I am not even sure how to figure out Edwin's math, his is not even comprehendible for me.
When I'm shopping, I always use Maria's method to figure out the price of things, therefore, I am 99% sure she is correct and Edwin is not. If it said that they both came with 23$, and the price of the book is now only 21.88, then yes, they have enough money to purchase the book.
and sorry this took long, I'm multitasking.
Answer:
y = 3/4x - 6 1/4
Step-by-step explanation:
I hope that the slope 3 4 - - means 3/4
Slope = 3/4
Using slope = 3/4 and the point (-1, -7) substitute into y = mx + b and solve for "b"
y = mx + b
-7 = 3/4(-1) + b
-7 = -3/4 + b
-7 + 3/4 = b 3/4 as a decimal = .75
-7 + .75 = b
-6.25 = b
The equation of the line is y = 3/4x - 6.25 or y = 3/4x - 6 1/4
Answer:
I believe it's A
Step-by-step explanation:
Not sure though.
Step-by-step explanation:
(3x+6x)+(9a-10a)
combine like terms
9x+-a
That's as far as it goes...
Sorry if it's wrong
