need help with 13 and 14

Answers

Answer 1

13) 9 over 4 × 4 over 3
9 × 4 over 4 × 3
36 over 12 = 3 over 1
Therefore, your answer would be 3 over 1

14) 7 over 5 × 20 over 9
7 × 20 over 5 × 9
140 over 45 = 3 and 1 over 9
Therefore, your answer would have to be: 3 and 1 over 9.

For the first one, you have to convert the fractions to an improper fraction. To do that you need to multiply the bottom denominator number (3) by the whole number (1) then you need to add the numinator, so 3x1+2= 5. You have to keep the denominator so 1 2/3 is equal to 5/3. Then do the same to 2 1/5, and you get 11/5. Now you have to find a common denominator, that's basically the smallest number that both numbers can go Into, the lowest common denominator for 3 and 5 is 15. So 3x5= 15, so we have to multiply the top number by 5 which is 25. So 5/3 is equal to 25/15, then 5x3= 15, so you need to multiply 11 by 3 which is 33. So 11/5 is equal to 33/15. Then you add them. Add the numinators (25+33=58. Then you keep the denominator 15. So when u add it it's 58/15 then you need to simplify that and you get 3 13/15.

The second one you turn them into improper fractions like I told you how to before (multiply the bottom number by the whole number then add he top number, then add he same denominator.) do that for both. Then you line them right next to each other and multiply across. (I just realized that they were the same number so they are equal to 5/3 and 11/5)
Then you do 5x11 and you get 55 then do 3x5 and you get 15. 55/15 is your answer, but you need to simplify it, you need to divide 55 by 15, (not all the way just the first number) so you do 15x3 and that's 45, then you subtract that from 55, and you get 10, so then you take your denominator (15) and you answer is 3 10/15. But when you simplify it it's 3 and 2/3

Two bands are marching in a parade there are 32 people in the first band 40 people in the second band the same number of people are marching in each row in each band what is the greatest number of people that could be marching in each row

Answers

Eight people in each row

Basically, this question is asking you to find what is the smallest number that both 40 and 32 are divisible by evenly?
The answer here is eight.
40/8 = 5
32/8 = 4
So the first band will have 4 rows of eight, and the second will have 5 rows.

During the 2007 baseball season, Wade was up to bat 10 more times than his teammate Dwight. Dwight batted 17 fewer times than another teammate, Ellis. The three players were up to bat a total of 1650 times. How many times did Ellis come to bat?

I only really need help making an equation because the ones I tried making didn't work.

Answers

This problem requires more than one equation, at least for me to get it to work ~this is how I did it

Wade = w Dwight = d Ellis = e Up to Bat = 1650
These are the equation to find each personw = d + 10e = d +17d = w - 10 or d = e - 17
This is the basic equation you have to plug the other equations into1650 = w + d + e
I solved for Dwight so I plugged in for w and for e1650 = (d + 10) + d + (d + 17) ~then I simplified1650 = 3d + 27 ~everything grouped together than matched1623 = 3d ~I subtracted 27 from both sides541 = d ~I divided both sides by 3Dwight batted 541 times

This is where I solved for Ellis since that is what the question waskede = d + 17 ~first equation
e = 541 + 17 ~plugged in 541 for d since that's how many times d battede = 558 ~finally simplified the equation

Ellis came up to bat 558 times in the 2007 baseball season

how to turn 5x+10y=15 in to slope intercept form (y=mx+b)

Answers

5x+10y=15
5x-5x=0
15-5x
10y=-5x+15
-5x /10 and 15/10
y=-1/2x +1.5

Final answer:

To convert the equation 5x+10y=15 into the slope-intercept form y=mx+b, subtract 5x from both sides and then divide by 10. The final equation will be y = -0.5x + 1.5, where -0.5 is the slope (m) and 1.5 is the y-intercept (b).

Explanation:

Converting the equation 5x+10y=15 into slope-intercept form (y=mx+b) involves isolating y on one side of the equation. The slope-intercept form of an equation is defined such that m is the slope and b is the y-intercept.

Here are the steps to convert this:

Start with the original equation: 5x + 10y = 15.Subtract 5x from both sides to get: 10y = -5x + 15.Divide every term by 10 to isolate y: y = -0.5x + 1.5.

The equation is now in the form y = mx + b. Here, the slope, m, is -0.5 and the y intercept, b, is 1.5, which is the point at which the line intercepts the y axis.

4. 5 • 12 • (–2)

1. 4 • (–3) • 5
so 4 x (-3) = -12 and then -12 x 5 = -60
2. (2.25 x 23) x 4
so (2.25 x 23) 51.75 and then 51.75 x4 = 207
4. 5 x 12 x (-2)
so 5 x 12 = 60 and then 60 x (-2) = -120

5 cubed is 5×5×5 (to the power of three)

In a power, the number used as a factor is called the base.

A power is an expression that represents repeated multiplication of the base by itself. It consists of a base raised to an exponent.

The base is the number that is being multiplied, and the exponent represents the number of times the base is multiplied by itself.

For example, in the expression 2³, the base is 2. It indicates that 2 is being multiplied by itself 3 times.
