Answer:
She read 1897 pages on day 53.
She read 52311 pages in 53 days.
Step-by-step explanation:
1st night=77 pages
2nd night=77+35= 112pages
This is called an arithmetic sequence. That means the terms in the sequence have a common difference.
y=35x+(77-35) is the equation that models this sequence
y=35x+42
Replace x with 53 to get the number of pages she read on the 53rd day
y=35(53)+42=1897
Now if you wanted to know the number of pages she read by the end of the 53rd day then you will need to add up all the pages she read on each day:
77+112+....+1897
=sum(35i+42, i=1..53)
=52311
Answer:
64!!!
Step-by-step explanation:
Multiply 63x2= 126 then multiply 97x3=291
126+291=417. he needs 500 hours now you will subtract 500-417=83 he needs 83 more hours to reach 500
Answer:
(-2) - 4 = -6
5 - (-5) =10
7 + (-4) = 3
Step-by-step explanation:
The additive inverse of a number is what you can add to that number for the sum to be zero. For real numbers, such as rational numbers, that means the additive inverse can be found by just flipping the sign of the number.
The additive inverse property says if you add a number and its additive inverse, then the sum is zero.
For example, let's use the number 3. The additive inverse of 3 is -3, since 3 + (-3) = 0. This is also true the other way around. The additive inverse of -3 is 3.
When subtracting rational numbers, remember that subtracting is the same as adding a negative! That means 3 - 3 is the same as 3 + (-3) or -3 - (-3) is the same as -3 + 3. Both of these sums involve a number and its additive inverse and they add up to zero.
Answer:
Below.
Step-by-step explanation:
This transformation is described by (x,y)---> (y,x).
G(4,1) ---> G'(1,4)
H(5,-4) ---> H'(-4,5)
I(2, -8) ----> I'(-8,2).
