Mrs Smith is completing a mathematics problem. She knows when 6 is added to four times a number, the result is 50. What would be

Lesechka [4]

EXPLANATION:

-To formulate an equation, you must first know what data the exercise gives us to locate them correctly.

data:

-6 that must be added to a number.

-four times a number that is equal to 4x

-a result that is equal to 50

Now with these data we formulate the equation:

$\begin{gathered} \text{Equation:} \\ 6+4x=50;\text{ } \end{gathered}$

if we solve the equation we have:

$\begin{gathered} 6\text{ }+4x=50 \\ 4x=50-6 \\ 4x=44 \\ x=\frac{44}{4} \\ x=-\frac{22}{2} \\ x=\text{ }-11 \end{gathered}$

Plz help me with 17 part a and b I will thank u

podryga [215]

Part A

There are 2 cups in a pint, so 2 x 3 = 6
Plus 5 cups,
1 quart is equal to 1/4 of a gallon, and there are 4 cups in a gallon,
and another quart is 4 more cups,
so add all of the cups together:
6 + 5 + 4 + 4 = 19

Kelly is incorrect, because I added all of the cups together and I got 19.

Part B

Since 4 cups fit in a quart, and she has 4 quarts, her quarts only hold 16 cups, which isn't enough, because there are 19 cups.

Hope this helped! If you have anymore questions or don't understand, please comment or DM me. :)

The formula for rate is r= d t Solve for d

son4ous [18]

Multiply your equation by the inverse of the coefficient of d to get d by itself.

$r=\dfrac{d}{t}\\\\rt=d\qquad\text{multiply by t}$

With d on the left, this is

... d = r·t
