We can start with the whole of 135, and find out 10% of that.
135/10 or 135 divided by 10= 13.5
This means that 1/10 of it is equal to 13.5, and that’s 10%. To find 20%, you want to do 13.5 x 2, and this will get you 27.
The answer is 27.
Yes, u are correct, hope this helped
Answer: 18
<u>Step-by-step explanation:</u>
3² * 3ⁿ = 3²⁰
3⁽²⁺ⁿ⁾ = 3²⁰
2 + n = 20
<u> -2 </u> <u> -2</u>
n = 18
Answer:
y = -1/2x + 2
Step-by-step explanation:
y = 2x - 3. The slope here is 2. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal, just flip the slope and change the sign.
slope = 2 or 2/1.....flip it.....1/2....change the sign...-1/2. So our perpendicular line will have a slope of -1/2.
y = mx + b
slope(m) = - 1/2
(2,1)....x = 2 and y = 1
now we sub and find b, the y intercept
1 = -1/2(2) + b
1 = -1 + b
1 + 1 = b
2 = b
so ur equation is : y = -1/2x + 2 <===
and u can check it with ur points....(2,1)
y = 2x - 3
1 = 2(2) - 3
1 = 4 - 3
1 = 1 (yep...it checks out)
