Answer:
x=1
y=2
Step-by-step explanation:
Multiply the second equation by 2
and then solve!
Here we must write and solve a linear equation to find the number of miles that Arun traveled in the taxi. We will find that Eva traveled 11 miles.
So we know that the taxi charges a fee of $4.10 and then a plus of $0.50 per mile.
So if you travel for m miles, the cost equation is:
C(m) = $4.10 + $0.50*m
Now, we know that for Eva the total fare (total cost) was $9.60, then we need to solve:
$9.60 = C(m) = $4.10 + $0.50*m
$9.60 = $4.10 + $0.50*m
$9.60 - $4.10 = $0.50*m
$5.50 = $0.50*m
$5.50/$0.50 = m = 11
This means that Arun traveled 11 miles in the taxi.

Step-by-step explanation:
Area is the product of two dimensions.
<u>If the scale factor is 1/4, the ratio of the areas will be: </u>
The smaller prism has a surface are of 45 cm².
<u>The larger prism has a surface area:</u>
Answer: 9cm
Step-by-step explanation:
The circumference of a circle is given as: = 2πr
where,
π = 3.142
r = radius = unknown
Since circumference = 56.52cm, we'll slot it into the formula which will be:
Circumference = 2πr
2πr = 56.52
2 × 3.142 × r = 56.52
6.284r = 56.52
r = 56.52 / 6.284
r = 8.99
r = 9cm approximately
