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:
2x+3=-13
x=5
Step-by-step explanation:
it says 2 times a number which would be the 2x, and it says the sum of that and 3 which would be 2x+3 and it says is 13. 2x+3=13
now solving it
2x+3=13
subtract 3 from both sides
2x=10
and divide 2 from both sides
x=5
Answer:
angle COD is right answer
First, you add the two ratio numbers to figure out what to divide your 28 cans of soda by.
3=4=7
Next, you divide this amount into your total amount of cans of soda.
28/7=4.
This means that for each one in the ratio, there is 4 cans. So you multiply both numbers in the ratio by 4.
3*4 = 12
4*4=16
So, your final answer is 12:16, or 12 cans of soda in one group, and 16 cans of soda in the other.
