6 0

Step-by-step explanation:

As ratio of desktops to laptops=3:4

Take no. of desktops= 3x

Take no. of Laptops=4x

Total no. of desktops+ Total no. of laptops = Total no. of computers

3x+4x=70

7x=70

x=10

Hence, the total no, of desktops= 3x

Hence, Total no. of desktops= 3×10

=30 desktops

Answer:

Step-by-step explanation:

Vertically opposite angles are equal.

8y + 36 = 14y -24                Subtract 36 to both sides

8y = 14y - 24 - 36               Combine

8y = 14y - 60                       Subtract 14y from both sides

8y - 14y = - 60

-6y = -60                             Divide by - 6

-6y/-6 = -60/-6

y = 10

===========================

x +48 = 64                        Subtract 48 from both sides

x +48 - 48 = 64-16

x = 16
