Subtracting fractions with unlike denominators 9/3-6/10

Answer:

(0,-16)

Step-by-step explanation:

Since you asked, simply, to know how a ratio is equivalent to another.

Ratios are like fractions in the way that they can be multiplied and simplified. 1:2, for example, can also be 10:20, 5:10, etc. This is inherent to the way a ratio works - say, for every 1 person, there are two cheese slices. This means that when the group gets larger, so does the amount of cheese slices.

Now, to find an equivalent ratio. You can simplify 4:6 by finding the GCF (greatest common factor) of these two numbers - something you can divide both of them by evenly. In this case, the GCF is 2. We divide both 'sides' by 2, and we get a simplified ratio of 2:3. You can then multiply this by different numbers (ones that are logical and could reasonably lead you to an answer on your worksheet or whatnot) until you find an equivalent ratio.

Answer:

Answer:

3x(2+n)+[7+n]

Step-by-step explanation:

The answer is kind of self-explanatory, but think of it this way.  If n=5, then the equation would be 3x(2+5)+[7+5]. First we would solve 2+5 which is 7. Then we would do 7+5 which is 12. We are now left with 3x7+5.

Answer:

x = -2/3

Step-by-step explanation:

x + 10 ÷ 6 = 1

Divide

x + 1 2/3 = 1

Subtract 1 2/3

x = -2/3

Also, as a girl, we do give some signs to people that we like, we start conversations with the person, we make eye contact and then look away (at least that what I do lol), flirts with you, agrees with you, wants to spend time with you, etc.

Answer:

standard: 5x-3y=5

slope intercept: y=5/3x-5/3

Step-by-step explanation:

so standard form is: ax+by=c

(a must be positive)

slope intercept form is: y=mx+b

(m is the slope of the line that the two points form)

first, find the slope:

(y1-y2)/(x1-x2)

(5-0)/(3-0)

slope=5/3=m

to do slope intercept, b is the y-intercept

to find that plug in one of your pairs of numbers like so,

y=mx+b

0=5/3x+b

b=-5/3

now we have slope intercept form!!

y=5/3x-5/3

to do standard form:

first, take your slope intercept form; y=5/3x-5/3

then subtract 5/3x from both sides making:

-5/3x+y=-5/3

multiply everything by -3 to get rid of the fraction and the negative like so:

5x-3y=5

and boom! standard form!

I always prefer going from slope-intercept to standard because its easier but its your choice! I hope I helped you!! Please mark brainliest!! Have a supertastic day

Answer: 57.5

Step-by-step explanation:

To solve this problem, you need to multiply the number of cups of flour per cup of milk times 5.

Step 1: Find how many cups of flour per cup of milk.

23/2 = 11.5 cups of flour per cup of milk

Step 2: Multiply the cups of flour per cup of milk, times the 5 cups of milk.

11.5 * 5 = 57.5 total cups of flour

Answer:

3/7 is the answer. It is 3 over 7

Answer:

-1/3 x 9x -1/3 x 30 + 2

-3x -10 +2

-3x - 8

Step-by-step explanation:

this is a distributive type of problem you distribute the -1/3 to the 9x and the 30 by distribute i mean multiply. if you dont know how to multiply this use the calculator but you multiply it by the 2 pairs of numbers in the parenthesis and then you just add the 2

Answer:

18 dollars

Step-by-step explanation:

15-6=9

9x2 (double it because she spent half)18

Answer:

D

Step-by-step explanation:

The constant of proportionality is 8 as seen by the equation:

y = 8x

8 will constantly be multiplied by x (the number of dollars earned) to solve for y (number of tickets sold)

The number 8 will not change

Therefore, 8 is the constant ot proportionality

Answer:

z = -3

Step-by-step explanation:

Simplifying

3z + -3 = 2z + -6

Reorder the terms:

-3 + 3z = 2z + -6

Reorder the terms:

-3 + 3z = -6 + 2z

Solving

-3 + 3z = -6 + 2z

Solving for variable 'z'.

Move all terms containing z to the left, all other terms to the right.

Add '-2z' to each side of the equation.

-3 + 3z + -2z = -6 + 2z + -2z

Combine like terms: 3z + -2z = 1z

-3 + 1z = -6 + 2z + -2z

Combine like terms: 2z + -2z = 0

-3 + 1z = -6 + 0

-3 + 1z = -6

Add '3' to each side of the equation.

-3 + 3 + 1z = -6 + 3

Combine like terms: -3 + 3 = 0

0 + 1z = -6 + 3

1z = -6 + 3

Combine like terms: -6 + 3 = -3

1z = -3

Divide each side by '1'.

z = -3

Simplifying

z = -3

Answer:

=3z+3=2z+6

=3z-2z=6-3

=z=3

Answer:

1. 30(8.75) + 11t = 400

2. 12.5 hours

Step-by-step explanation:

1. What is given is you work for 30 hours per week at a gas station for $8.75 an hour. You also work as a landscaper for $11 an hour. You want to a make a total of $400 per week.

30 hours and $8.75 an hour would be equivalent to 30(8.75)

We don’t know how many hours you work as a landscaper but you earn $11 an hour, which is equivalent to 11t

Finally, you want to earn a total of $400 a week, which means the sum equals 400

30(8.75) + 11t = 400

2. 30(8.75) = 262.5

400 - 262.5 = 137.5

137.5 / 11 = 12.5

Answer:

The zeros of the function are x = 4/3 or x = -2

Step-by-step explanation:

To find the zeros of the function, we set f(x) to zero

Thus;

(3x-4)(x + 2) = 0

3x - 4 = 0

or x + 2 = 0

3x = 4 or x = -2

x = 4/3 or x = -2

Answer:

x= 13

Step-by-step explanation:

Answer:

the value of x is 5/7 which is in fraction

Answer:  x = 5/7

Step-by-step explanation:  2x/3 + x/2 =5/6

To use a least common denominator, divide LCD by the original denominator and multiply the original numerator by the result.

for 2x/3  6÷3=2  2×2x=4x so that becomes 4x/6

for x/2    6÷2=3  3× (invisible) 1 = 3x, so that becomes 3x/6

combine 4x/6 + 3x/6 = 7x/6  

Back to the original equation, substituting the calculated term:

7x/6 = 5/6   Multiply both sides by 6 to simplify (6)(7x/6) = (6)(5/6) 6's "cancel"

7x = 5 .  Divide both sides by 7 to solve for x  7x/7 = 5/7

x = 5/7

A parallel line has the same slope as the original equation. Therefore, the slope (m in y=mx+b) will be 5. From there, we can use the point-slope formula and convert it into the slope-intercept formula (y=mx+b).

Point-slope is:

y-y₁=m(x-x₁)

Plug in our known values:

y-(-2)=5(x-(2))

Distribute and set it equal to y:

y+2=5x-10

y=5x-12

Answer:

  B) x scale of -15 to 15

  C) y scale of 0 to 15

Step-by-step explanation:

The change in y-value is 1/4 of the change in x-value, and the y-intercept is 8. That means a y-scale of -30 to 30 would not be well-utilized over a small range of x. (It would take an x-range of about 200 to make much use of that y-scale.)

An appropriate y-scale is one that has 8 near its middle. The corresponding x-scale is then roughly ±4 times half the y-scale. The closest choices are ...

  -15 ≤ x ≤ 15 . . . . choice B

 0 ≤ y ≤ 15 . . . . . . choice C
