Answer:
C, Length = 39.4 cm; width = 7.9 cm
Step-by-step explanation:
The permimeter of a rectangle is 2 times the width + 2 times the length or 2(l + w)
The length is 4 times w plus 7.8.
So: 2w+2(4w+7.8)=94.6
= 2w+8w+15.6=94.6 (Factor out the brackets)
= 10w+15.6=94.6 (Combine like terms)
= 10w=79 (Subtract 15.6 from both sides)
= w=7.9 (Divide both by 10).
So, the width is 7.9 cm and the length is 39.4 cm (4 * 7.9 + 7.8)
Answer:
15/80 = x/1600
multiply both sides of this equation by 1600 to get:
1600 * 15/80 = 1600 * x/1600
80 goes into 1600 20 times.
1600 goes into 1600 1 time.
equation becomes:
20 * 15 = x
solve for x to get x = 300.
300 students will most likely buy a tamale based on the survey
Let the number of saxophone players be
.
Then, the number of trumpet players will be 
If saxophone players are three times the number of trumpet players then we have the relation

This is a linear equation in s. we expand bracket to obtain,

We group like terms to get,


This implies that

The number of trumpet players are;

Therefore there are 5 trumpet players.
Answer:
Lillian will have $170.56 in one year
Step-by-step explanation:
First we have to figure out what is 6.6% of 160.
160 * 6.6% = 10.56
Now we just add 160 with the 6.6% to figure out the answer.
160 + 10.56 = 170.56
So, the answer is 170.56 dollars.
