Step-by-step explanation:
The actual length of the dust termite observed under the microscope is 1.5 mm
- The scale of image produced under the microscope 100 : 1
- This means image is magnified 100 times its original size as microscopes are used to enlarge or magnify the size objects.
- Taking the measured size of the dust termite under the microscope in millimeter = 150 mm
The actual length of the termite will be :
- Measured size under microscope ÷ 100
Therefore, the actual length of the dust termite is about 1.5 mm

Answer:
x=-1
y=-1
Step-by-step explanation:
-6x + 5y =1 ......equation (1)
6x + 4y = –10 ......equation (2)
adding equation (1) to equation (2)
9y=-9
9y/9 =-9/9 (dividing both side by the coefficient of y)
y=-1
subtituting the value of y =-1 into equation (2)
6x+4(-1)=-10
6x+(-4)=-10
6x-4=-10
6x=-10+4(making constant to be at one side and the variable at the other side)
6x=-6
x=-6/6
x=-1
