Answer:

y = 36/5

Step-by-step explanation:

The formula for direct variation is

y = kx where k is a constant

We know y =12 and x= 5

12 = k*5

12/5 = k

The formula is

y = 12/5 x

Now find y = when x=3

y = 12/5 *3

y = 36/5

Answer:

(3x-17)°+(x+40)°+(2x-5)°=180°[sum of angle of triangle]

6x°+18°=180°

6x°=180°-18°

x°=162°÷6°

x°=27°

Again,

=3x-17. 2x-5. x+40°

=3×27-17. =2×27-5. =27+40

=64°. =49°. =67°

Step-by-step explanation:

Let's turn each mixed fraction into an improper fraction:

$2 \frac{1}{2} =\frac{2}{2} +\frac{2}{2} +\frac{1}{2} =\frac{5}{2}$

$3\frac{1}{5} =\frac{5}{5} +\frac{5}{5} +\frac{5}{5} +\frac{1}{5} =\frac{16}{5}$

Multiply:

$\frac{5}{2} \times \frac{16}{5} =\frac{80}{10}$

Simplify:

$\frac{80 \div 10}{10 \div 10} =\frac{8}{1} =8$

8 is your simplified product.
