Answer:
Y=7.05
X= 11.6
Step-by-step explanation:
Equate both equations to zero
3x+5y=70--------equation 1
7x-3y=60---------equation 2
From the equation above
a1=3, b1=5, c1=-70
a2=7, b2= -3, c2=-60
By applying the cross multiplication method
x/b1c2-b2c1= y/a2c1-a1c2= 1/a1b2-a2b1
x/(5)(-60)-(-3)(-70)=y/(7)(-70)-(3)(-60)=1/(3)(-3)-(7)(5)
x/-300-(-210)=y/-490-(-180)=1/-9(-35)
x/-510=y/-310=1/-44
x/-510=1/-44 , y/-310=1/-44
-44x=-510 , -44y= -310
x=11.6 , y=7.05
Thus, the value of x is 11.6 and the value of y is 7.05
Step-by-step explanation:
Given the information that the scale of 1 : 60
- a. Plot a point which is 240 cm from A and is on the line AB.
Scale = 1 : 60
<=> 240 cm = 4 cm
Use a compass with the width = 4 cm and the center is point A then you draw an arc such that it intersect line AB . After that, we will have a point (the intersection point) which is which is 240 cm from A and is on the line AB
- b) Plot a point which is 240 cm from A and is on the line CD.
Scale = 1 : 60
<=> 240 cm = 4 cm
The same way in the answer A, use a compass with the width = 4 cm and the center is point A then you draw an arc such that it intersect line CD . After that, we will have a point (the intersection point) which is which is 240 cm from A and is on the line CD
- c) Plot a point which is 240 cm from A and is 96 cm from the line CD
96/60 = 1.6 cm
We will D draw a line parallel to CD at a distance of 1.6 cm, then we will use use a compass with the width = 4 cm and the center is point A then you draw an arc such that it intersect line CD.
Hope it will find you well.

Answer:
(2, 5)
Step-by-step explanation:
The longest side of the triangle will be the side with the coordinate (1,4) and (3,6) due the value of the distance between them;
Midpoint = (x1+x2/2, y1+y2/2)
X = 1+3/2
X = 4/2
X = 2
Y = 4+6/2
Y = 10/2
Y = 5
Hence the required midpoint (X, Y) will be at (2, 5)
Answer:
X=1 because 2+5=7 then X=1 cause 1*2=2
