1. Multiply x and 3y by x-2
x^2-2x (i.e. x*x=x^2, -2*x=-2x)
3yx-6y (i.e. 3y*x=3yx, 3y*2=6y)
2. Multiply x+y by -4
x*-4= -4x
y*-4=-4y
3. Multiply 2x+3y by -1
2x*-1=-2x
3y*-1=-3y
4. Combine like terms
x^2 3yx -2x -6y
-2x -3y
-4x -4y
-------------------------------------------
x^2 +3yx -8x -13y

Answer:
Dorita can make 18 whole miniature cups of dessert.
Step-by-step explanation:
Given:
Amount of pudding she had =
Now the given number is in mixed fraction so we will convert in Improper fraction.
To convert mixed fraction into Improper fraction we need multiply the whole number part by the fraction's denominator then add that to the numerator and then write the result on top of the denominator.
can be Rewritten as
Amount of pudding she had =
Amount of pudding required for each miniature cup =
We need to find the number of whole miniature cups of dessert can Dorita make.
Solution:
Now we can say that;
number of miniature cups can be calculated by dividing Amount of pudding she had by Amount of pudding required for each miniature cup.
framing in equation form we get;
number of miniature cups =
Hence Dorita can make 18 whole miniature cups of dessert.
Answer:
Step-by-step explanation:
In order to find an equation of a line with two given ordered pairs. We have to find a slope first which we can do by using the formula below.
m-term is defined as slope in y = mx+b form which is slope-intercept form.
Now we substitute these ordered pairs (x, y) in the formula.
After we calculate for slope, we substitute m-value in slope-intercept form. The slope-intercept form is
We already know m-value as we substitute it.
We are not done yet because we need to find the b-term which is our y-intercept. (Note that m-term is slope while b-term is y-intercept)
We can find the y-intercept by substituting either (-14,1) or (13,-2) in the equation. I will be using (13,-2) to substitute in the equation.
Finally, we know b-value. Then we substitute it in our equation.
Yes it is a true inquation.
Answer:
D.
90 x 1/2 = 45 km
The rate is 90 miles per hour and 30/60=1/2 so we multiply 1/2
