Explain how to simplify the expression （-8）+（-3）+（-4）（7）/14+9（-2）. Show the updated expression after each step you take.

1 answer:

7 0

Follow the order of operations. Multiplication and division being Equal to each other you’ll need to go from left to right just like you are reading a book.

(-8)+(-3)+ (-28) / 14+9 (-2)

(-8)+(-3)+ (-2)+9 (-2)

(-8)+(-3)+(-2)+(-18)

Then once all multiplication and division is completed you can move on to addition and subtraction. Same as before left to right.

-11+ (-2)+(-18)

-13+ (-18)

-31 is the answer

the ratio of stars to stripes is 50 to 13. If there were 400 stars in the parade, how many stripes were there?

Black_prince [1.1K]

I believe it's 104. You would set it up as a fraction so:
50/13 and 400/x.
Then you would cross multiply so 13x400 is 5,200. So this divided by 50 = 104. Hope I helped!

Find the equation in slope-intercept form that describes a line through (–1, 1) and (2, 3)

Butoxors [25]

Answer:

y = 2/3x + 5/3

Step-by-step explanation:

The slope of the line is ...

slope = (change in y)/(change in x) = (3-1)/(2-(-1)) = 2/3

Then the point-slope form of the desired line can be written ...

y = m(x -h) +k . . . . . slope m through point (h, k)

y = 2/3(x +1) +1 . . . . slope 2/3 through point (-1, 1)

y = 2/3x + 5/3 . . . . . . simplify to slope-intercept form

MIDDLE SCHOOL MATH- 4 QUESTIONS

Contact [7]

Answer:

( I am assuming that these are all fractions)

1. 14 $\frac{4}{7}$

2. 8

3. $\frac{4}{15}$

4. 5 $\frac{8}{11}$

Step-by-step explanation:

1. First you have to convert 15 into a fraction but it must have the same denominator causing the equation to look like 105/7 - 3/7= 102/7. But you cannot just leave the fraction like that it must be simplified 14 $\frac{4}{7}$

2. Three-fifths of an hour is 36 minutes. You would next multiply 5 by 60 which would the hours into minutes 5 x 60 = 300. You would then divide 300 by 36 which would give you 8.3333333333, which I just simplified it to 8

3. In order for you to multiply a fraction you would first multiply the top then the bottom. 12 x 6= 72, 15 x 18= 270. The fraction would look like 72/270 which is simplified to $\frac{4}{15}$ .

4. First I changed the fractions into improper fractions causing the fraction to look like 36/8 x 14/11 (I got these answers by 8 by 4 then adding 4, then for the next fraction I multiplied 11 by 1 then added 3.) 36 x 14= 1224, 11 x 8= 88 the fraction would look like 1,224/88 you would simplify to 5 $\frac{8}{11}$

Hope this helps
