First, distribute (turning everything into a decimal at first to make more sense) : .4x - 3 + .6x = 4.25
Combine like terms : x - 3 = 4.25
Add 3 to both sides : x = 7.25
As a fraction : 7 1/4
Answer:
155
Step-by-step explanation:
2325 / 15
15 goes into 2325 155 times.
Would the answer be 176? I’m not sure but i’m curious
Answer:
The equation of the boundary of the region is (x+2)² + (y-1)² = 25
Step-by-step explanation:
The satellite is positioned at (-2,1) and can sense the presence within 5 miles of its position.
The boundary of the region is a circle with center (-2,1) and radius 5.
The equation of the circle with center (h,k) and radius r is given by
(x-h)²+(y-k)²=r²
The equation of the circle with center (-2,1) and radius 5 is given by
(x+2)²+(y-1)²=5²=25
(x+2)² + (y-1)² = 25 is the required equation of the boundary of the region.
