Answer:
The base is 4cm and the height is 5cm.
Step-by-step explanation:
This is a solve the system question. Call H the height of the triangle and B the base. The question tells us:

and

Sub the first equation into the second (as H is already isolated). You will end up with a quadratic equation - solve that any way you wish (e.g. quadratic formula). I've provided the factored form below which shows you the roots:

In this question, we take B=4. You can't have a negative side length so the other answer is eliminated. Now sub the value for B into either of the original equations. I'll use the first, again because H is already isolated:

Answer:
it 8
Step-by-step explanation:
4^3 is 64
2^3 is 8
64/8 is 8
Answer:
Given system of equations:

To solve by substitution, equate the equations and solve for x:

Therefore, the x-values of the solution are
and
.
To find the y-values of the solution, substitute the found values of x into the functions:




Therefore, the solutions to the given system of equations are:
and 
Answer:
a) 72
b) $259.2
Step-by-step explanation:
A- The bus travels 40 miles on 8 gallons of gasoline. The bus is traveling 360 miles in total.
360/40= 9
9*8= 72
B- $3.60 per gallon and 72 gallons in total.
3.60*72=259.2
$259.2
