We can use the distributive property for this:
-5(3 - 6) = -45
-15 + 30 = -45
15 = -45.
Soooo that's like the farthest you can simplify... and both sides aren't equal...sooo yeah.
Answer:
267 (please double check this!!!)
Step-by-step explanation:
Separate the block into sections that you can find the volume for easily and figure out the measurements for each
the two smaller blocks on top will be symmetrical
the bottom area is 5 high and 3 deep and you get the length by adding 4+5+4 because that's the length of the whole thing
so 13*3*5 = 195
The two smaller blocks is just adding a *2 once you figure out the one
it's 3 deep still and 4 wide, if you subtract the total height from the height given of the bottom part you get 3
3*4*3 = 36
you have another one of those blocks so it'd be 36*2
then you add them both 72+195 = 267
Answer:
(x - 2)
Step-by-step explanation:
Given the quadratic
x² - 7x + 10
To factor consider the factors of the constant term ( + 10) which sum to give the coefficient of the x- term ( - 7)
The factors are - 5 and - 2 since
- 5 × - 2 = + 10 and - 5 + (- 2) = - 7, thus
x² - 7x + 10 = (x - 5)(x - 2)
Answer:3x/5 + 4/5
Step-by-step explanation:
So, if Dylan has x dollars and he bought 3 tickets with them, the tickets were priced at k dollars per ticket. If he bought 5 tickets with the x dollars and saved 12 total dollars, it would be the same as buying the tickets with x-12 dollars, so we have:
So, with this we have:
If we're looking for a number that satisfies these constraints, we can work with modular arithmetic. We have:
So, we can use the chinese remainder theorem here. So, we clearly have x=3k, which means:
So, since we have x=3k, we also have x=3(5j+4)=15j+12.
So, clearly j=0 won't work so we should have j=1. That means our money per ticket for the five tickets is:
And our money per three tickets is:
This is easily verifiable. Three tickets needs 27 dollars and 5 tickets needs 15 dollars, which is 12 less than 27 dollars. So we have our money per three dollar ticket at 6 more than money per five dollar.
