Answer:
(C)90 – 10y = 5x
Step-by-step explanation:
Given:
x = number of times she hiked the 5-mile trail
- Then, total Distance covered on the 5-mile trail =5x
y = number of times she hiked the 10-mile trail
- Then, total Distance covered on the 10-mile trail =10y
Maria hikes a total of 90 miles
Therefore, total distance hiked can be represented by the equation:
5x+10y=90
Subtract 10y from both sides, we have:
5x=90-10y
This is option C.
Answer:
x = 5
Step-by-step explanation:
The length of line segments joining a common point to tangents are always equal.
RS = RQ = 2
PW = PQ = 3
x = PQ + QR = 3 + 2 = 5
Answer:
x=-5
Step-by-step explanation:
25 - 3x = 40
-3x + 25 =40
-3x +25--25=40-25
-3x=15
-3x÷-3=25÷-3
x=-5
Answer:
Step-by-step explanation:
P=(3.14)(d) diameter divided by 2 equals radius
P=(3.14)(13)
P=40.82
A=(3.14)(6.5)(6.5)
A=(3.14)(42.25)
A=132.665
The total length of the circle is calculated by the following formula:
Lenght = 2.π.r
As r = 4c
Then,
Lenght = 2.π.4
Lenght = 8π centimetrs
Now use the rule of 3
But we have to know:
...<..> ...
Then,
8π ________ 2π <= 360°
x ________ 3π
2π . x = 8π . 3π
x = (8π . 3π) / 2π
x = (8 . 3π)/ 2
x = 12π centimenters
x ~ 37,69 c
