2x + 3y = 630
x + y = 245 then you want to get rid of x so in the second equation × by -2 and get -2x -2y =-490 subtract this equation from the first to get y=$140 substitute 140 in for y and get x= $105 and 2x=210 and 3y=420 210 +420=630
Answer:
The slope is zero
Step-by-step explanation:
.........
The answer is 300 decigrams
Answer: D
Step-by-step explanation:
Remember that the Opposite side to an angle is in the same order of length as the Angle. So, 
. Using Cross multiplication, this answer can be solved:
, 60 x 12 = 720, and 90 x 8 = 720. N = 8.
, 30 x 12 = 360, and 90 x 4 = 360. N = 4
The distance between the points (4, 3) and (1, -1) on the coordinate plane will be 5 units. Then the correct option is C.
<h3>What is the distance between two points?</h3>
The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:
D² = (x - p)² + (y - q)²
The points are given below.
(4, 3) and (1, -1)
Then the distance between the points will be
D² = (4 - 1)² + (3 + 1)²
D² = 3² + 4²
D² = 9 + 16
D² = 25
D = 5 units
Then the correct option is C.
