Answer:
X=0.2
Step-by-step explanation:
0.17x+1.2=1.234
0.17x=1.234-1.2
0.17x=0.034
17x=3.4
x=3.4/17
x=0.2
Answer:
x = -11
Step-by-step explanation:
Because 3 x -11 = -33 and
8 -(-33 = 41
B Myra should have multiplied 4.5 and 2.1 first.
Answer:
x=0.5
Step-by-step explanation:
32x+16=32
-16 -16
32x=16
÷32 ÷32
x=0.5 or x=1/2
Suppose we have two points, A= (1,2) and B=(2,5)
We need to divide the line segment AB obtained by joining these 2 points, in a ratio 2:3,
Then, to find the coordinates of the point (x,y) which will divide the line segment AB (x1,y1) and (x2,y2) we will use the formula,
x=(mx1 + nx2)/(m+n)
y=(my1 + ny2)/(m+n)
Where m:n is the ratio in which it divides
Thus, coordinates will be x= (2*1 + 3*2)/(2+3)
Or x = 8/5
And y = (2*2 + 5*3)/(2+3) = 19/5
Thus the coordinates of the point are (8/5, 19/5) which divide the line in 2:3 formed by coordinates (1,2) and (2,5)
