Answer:

1. y=kx

2. y=60

Step-by-step explanation:

y is directly proportional to x

y=kx

Find Constant K, when y=30 & x=6

Make K the subject of the formula first

K=y/x

K=30/6

k=5

When k is 5, x is 12, find y

y=kx

y=5×12

y=60

Help pls dont give just the answer pls step by step so i can understand

Irina-Kira [14]

Answer:

y=14

Step-by-step explanation:

Since this is an isosceles triangle due to opposite sides being congruent, the base angles would also be congruent.

$50 = 2x \\x=25$

plug in 25 in 2x and you would get 50°

Since the sum of a triangle is 180° you could set up an equation $50+50+5y+10=180$

Then, add 50+50=100+10=110

then you would then have $5y+110=180\\$

subtract 110 from 180, leaving you with 70

$5y=70$

then divide and you would get 14

Check:

5(14)+10+50+50= 180
