Please help me i need to find the value of x and y :))

X=14, Y=145

Step-by-step explanation:

We'll start by finding x. We know that angles that make a line are 180 degrees. Therefore we can say

5x-15+9x-1=180

add the similar numbers

14x-16=180

add 16

14x=196

divide by 14

x=14

Now to find y, we will solve for 9(14)-1= 125 and set that equal to y-20

y-20=125

add 20

y=145

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
