we know that
cup of flour is used to make
dinner rolls.
Part a) How much flour is needed to make one dinner roll?
by using proportion

therefore
the answer Part a) is
To make one dinner roll is needed
cup of flour
Part b) How many cups of flour are needed to make 3 dozen dinner rolls?
Multiply the value obtained in part a) by 
so


therefore
the answer Part b) is
To make
dozen dinner rolls are needed
cup of flour
Part c) How many rolls can you make with 5 2/3 cups of flour?

by using proportion

therefore
the answer part c) is
rolls
Answer: Height = 8 m
Step-by-step explanation: We have to find h...
We're given two values
A = 60
B = 15
60 is equal to 1/2 x 15
Solve for h:
h = 60 / (1/2 x 15)
h = 60 divided by 7.5
h = 8
I hope this helps!
In order to solve this, start by adding 1 to both sides of the equation.
m-1=2
+1 +1
-----------
m=3
The solution to your equation is 3.
You can also check to see if this is true by replacing m with 3.
m-1=2
3-1=2
Answer:
False
Step-by-step explanation:
If we have a factor then the remainder after the division will be zero.
Answer:
x = 42
Step-by-step explanation:
The marked angles are supplementary, so their sum is 180°.
(2x +8) +(2x +4) = 180
4x +12 = 180 . . . . . . . . . simplify
x +3 = 45 . . . . . . . divide by 4 (because we can)
x = 42 . . . . . . subtract 3

<em>Additional comment</em>
A "two-step" linear equation like this one is usually solved by subtracting the unwanted constant, then dividing by the coefficient of the variable. Here, we have done those steps in reverse order. This makes the numbers smaller and eliminates the coefficient of the variable. Sometimes I find it easier to solve the equation this way.
