2 + 6 = 8. 2 is left. 6 is left.
2c+5t=43
c=(43-5t)/2
8c+3t=36 and using c found above in this equation gives you:
4(43-5t)+3t=36
172-20t+3t=36
-17t=-136
t=8, and since c=(43-5t)/2
c=1.5
So a table costs $8.00 to rent and a chair costs $1.50
By Pythagoras Theorem,
the length of the other leg= (63^2-52^2)^1/2
hope this helps :)
The measure of angle RML is of 130º.
<h3>What is the value of x?</h3>
Angle NML is the sum of angles NMR and RML, hence:
NML = NMR + RML.
The given measures of the angles are:
Hence we can solve the equation for RML to find the measure of angle RML, as follows:
NML = NMR + RML
156 = 26 + RML
RML = 130º.
The measure of angle RML is of 130º.

Answer:
Step-by-step explanation:
Let O=number of oranges and A=number of apples.
O+A=20
O=20-A
1.25A+0.95O=22.60, using O found above makes this become
1.25A+0.95(20-A)=22.60
1.25A+19-0.95A=22.60
0.3A+19=22.60
0.3A=3.6
A=12, since O=20-A
O=20-12
O=8
So she bought 8 oranges and 12 apples. The question really only asks for the number of apples bought.
12 apples were bought.
