T would equal negative 30
Answer:
the first part of the book has 659 pages and the second part has 723 pages
Step-by-step explanation:
First we have to raise 2 equations, one that shows us the relationship between one part of the book and the other, and another equation that shows us that together they give us the total of pages
x = second part
y = first part
x = y + 64
x + y = 1382
As the first equation tells us that x = y + 64 we will replace x in the second equation with (y + 64)
x + y = 1382
(y + 64) + y = 1382
y + y = 1382 - 64
2y = 1318
y = 1318/2
y = 659
now we replace in the first equation to y by its value
x = y + 64
x = 659 + 64
x = 723
so the first part of the book has 659 pages and the second part has 723
4. B is the answer
5. A is the answer ( y is the same , x are the opposite)
6. C
7. D
Answer:
<h3>2x + 5y = –15.</h3>
Step-by-step explanation:
We are given coordinates of the line passed through (–5, –1) and (10, –7) .
Applying slope formula,
Therefore,
Therefore, slope is .
Applying point-slope form 
we get
On multiplying both sides by 5, we get
5y+35=-2(x-10)
5y+35=-2x+20
Adding 2x on both sides, we get
5y+25+2x=-2x+20+2x
2x+5y+35=20
Subtracting 35 from both sides, we get
2x+5y+35-35=20-35
2x+5y=-15.
Therefore, required equation is :
<h3>2x + 5y = –15.</h3>
Answer:
2194.8
First, 124 times 2.95 then you get 365.8 and finally you multiply by 6 and get you answer.
