Answer:

Answer:

Step-by-step explanation:

6x-5y=15

x=y+3

6x-5+3=15

       -3    -3 (take from both sides)

6x-5=12

    +5   +5   (add to both sides)

6x=15

6 /15=.4

x=.4

y=+3

I probably did that wrong but that i the overall concept

Answer 2
Answer:

Answer:

x=0

y=-3

the problem is true

Answers

45/100 or 9/20 because:
5 5/8=5.625 and 1/8=0.125 and 5.625/0.125=45
and 45 as a fraction is 45/100 or 9/20
8/8 are in one whole number. 8 × 5 = 40. 5/8 (from the fraction) 40 + 5 = 45 45 "8"'s

I asked this question a couple of minutes ago and I feel like it isn't being understood completely so I edited the question to specify a little bit and posting it again. I am hoping you all understand it now and give me the best results. A huge thank you to all who attempts to answer!

Answer:

Look at explanation plz

Step-by-step explanation:

1) so we know that b cannot be anything lower than 0

So let’s substitute -7 in place of c:

x^2+bx-7

Factors of -7: 7,-1. -7,1

Only factor pair that Will not result in a negative or 0: 7,-1

Integers for B: 7,-1

Let’s do the same with number 2:

X^2+bx-3

Factors of -3: 3,-1. -3,1

Only factor pair that will not result in a negative or 0: 3,-1

Integers for B:3,-1

3) you know the drill:

6= 3,2 -3,-2. 6,1 -6,-1

Positive integers of 6: 3,2 or 6,1

Values for B: 3,2 OR 6,1 your choice

4) 12= 12,1. -1,-12. 4,3. -4,-3 6,2. -6,-2

Values for B: 12,1 or 4,3 or 6,2

I think the answer is 3. C= -3 and integer 2

Emmanuel wants to tile his rectangular floor. he has two kinds of tiles to choose from, one of which is larger than the other. emmanuel hired your services to help him decide which tile to use.a.what area will be covered by 7"x7" tile? 21"x21" tilwe
b.if the rectangular floor has dimension of 420" by 630"
c.how many big square tiles are needed to cove rthe rectangular floor?
d.if each small tile costs P15.00 and each big tile costs P60.00which which tile should emmanuel use to econimize in tiling his floor? why?

Answers

a).
The 8" by 7" tile covers 49 square inches.
The 21" by 21" tile covers 441 square inches.

b).
The area of the floor is (420" x 630") = 264,600 square inches.

c).
It would take (264,600) / (441) = 600 large tiles to cover the floor.

d).
Emmanuel should use the big tiles to cover his floor.
-- A big tile costs 4 times as much as a small tile, but it has 9 times
as much area as a little tile has, so it is a better buy.
-- Plus, he would have to pay the floorman a lot more to glue down 5,400 tiles
than he will have to pay to glue down only 600 tiles.
-- Since he has hired my services to advise him, I will charge him only 15%
of the difference if he takes my advice, so he will still be money ahead.
