Answer:
A reasonable estimate for the solution is the point (1.1,-1.9)
Step-by-step explanation:
we have
-----> equation A
----> equation B
Solve the system by graphing
Remember that the solution of the system of equations is the interection point both graphs
using a graphing tool
The solution is the point (1.091,-1.818)
see the attached figure
therefore
A reasonable estimate for the solution is the point (1.1,-1.9)
Answer:
The number of adult tickets are 57.
Step-by-step explanation:
Given,
Total number of tickets = 156
Total money = $1077.60
Solution,
Let the number of adult be x and of child be y .
So, Total number of tickets = Number of adults + Number of child
Now, according to question;
Total money =
On multiplying by 10 on both side, we get;
Now multiplying equation 1 by 53 then subtract it from equation 3, we get;
Since x is the number of adults,
Number of adults=57
Number of child = y = 156-57=99
Thus the number of adult tickets are 57.
Answer:
<em>There are 72 crayons in the box</em>
Step-by-step explanation:
<u>Fractions</u>
To solve this problem we'll manage numbers as fractions to keep the precision up to the end of it.
Lynn has a box of crayons. It's given 4/9 of the crayons are blue. The remaining crayons are:
From that portion, 65% are red, or equivalently, 35% are yellow.
We write 35% as a fraction:
Thus, the portion of yellow crayons is:
This fraction of x crayons is equal to 14, thus:
x = 72
There are 72 crayons in the box
