2. 35 45 n; 10, 11, 12

Answers

Answer 1

Answer: 35 = 45 - n
think of it as money
45 dollars take away how many (n) = 35 dollars
45 - n =35
or you can subtract 45 from both sides
-n = 35-45
-n = -10
divide by -1 from both sides
n = 10

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

there is a total of 25 bicycles. if the ratio of gray bicycles to black bicycles is 6 to 9 how many of them are black?

Answers

25 bicycles
gray : black
6 : 9 (6+9=15)

25 divided by 15 = 1.666666667
x 9 (that's how many blacks)
= 15
there are 15 blacks

Final answer:

To find the number of black bicycles in a total of 25 bicycles given a ratio, divide the total number of bicycles by the total number of parts in the ratio and multiply by the number of parts representing black bicycles.

Explanation:

To find the number of black bicycles, we first need to find the total number of parts in the ratio. The ratio of gray bicycles to black bicycles is 6 to 9, which means the total number of parts is 6 + 9 = 15. We can then calculate the number of black bicycles by dividing the total number of bicycles by the total number of parts and multiplying by 9. So, the number of black bicycles is (25/15) x 9 = 15 bicycles.

You increase the size of a page by 30%. Then you decrease it by 30%. What is the size of the page now?

Answers

Lets use 1 to solve this problem because it is easiest to show.

Multiply 1 by 1.3 for a 30% increase (1*1.3=1.3).

Then multiply 1.3 by .7 for a 30% decrease. (1.3*.7=.91)

Therefore the page had a 9% reduction from its original size or is 91% of its original size.

Answer:

Smaller the size you started with

Step-by-step explanation:

Because for example 100 times .30 is 30 100+30=130 and 130 times .30 is 39 100-39=91. 100 > 91
