Answer:
She can buy 11 tokens
Step-by-step explanation:
8/4.40=x/6.05 (i set this up as a proportion. tokens/price=tokens/price)
4.40x=48.8 (cross multiplied)
x= 11 (divided both sides by 4.40)
Answer:
The answer in the procedure
Step-by-step explanation:
we have
2x-3y=-1 ----> equation A
3x+3y=26 --> equation B
Solve the system by elimination
Adds equation A and equation B
2x-3y=-1
3x+3y=26
----------------
2x+3x=-1+26
5x=25
x=25/5
x=5
Find the value of y
substitute the value of x in equation A or equation B and solve for y
2(5)-3y=-1
10-3y=-1
3y=10+1
y=11/3
Answer:
28/9
Step-by-step explanation:
22/9 = 2.444444...
24/9 = 2.66666...
26/9 = 2.88888...
28/9 = 3.1111111...
The value of k is
<h3>How to solve the simultaneous equation?</h3>
Given:
x-y=k.............(eq i)
2x²+y²-15..............(eq ii)
We would make y the subject formula in eq ii
2x²+y²-15= 0
2x² + y²= 15
y²= 15-2x²
y= ...........(eq iii)
Substitute the value of y into eq i
x-(= k
x- (= k
k=
