Turn the percent into a decimal which is .20 and then multiply
.20 time 3 is equal to .60
Answer: .60
I think the answer is 7.725 so sorry if I’m wrong but see if that answer is correct
Answer:
Answer:
\{ {{20x+30y=280} \atop {y=4x}} .{
y=4x
20x+30y=280
.
Where xx is the number of small boxes sent and yy is the number of large boxes sent.
Step-by-step explanation:
Let be xx the number of small boxes sent and yy the number of large boxes sent.
Since each small box can hold 20 books (20x20x ), each large box can hold 30 books (30y30y )and altogether can hold a total of 280 books, we can write the following equation to represent this:
20x+30y=28020x+30y=280
According to the information provided in the exercise, there were 4 times as many large boxes sent as small boxes. This can be represented with this equation:
y=4xy=4x
Therefore, the system of equation that be used to determine the number of small boxes sent and the number of large boxes sent, is:
\{ {{20x+30y=280} \atop {y=4x}} .{
y=4x
20x+30y=280
.
Answer:
the answer is .6
Step-by-step explanation:
so 30 minus 24 is 6 turn 6 into percentage which is 0.6
63/80 x 100 = 78.8%
You divide normally but multiply by 100 (moving the decimal over two places).
