Basically the question is asking YOU when you hear “system of equations” what do you think about it - what do you already know about system of equations. Basically. Btw enjoy this picture.
I would say the answer is 95.9 not to sure but I’m pretty confident
Let's call the left side of this tirangle y and downside z.
3² + 6² = y²
y² = 45
y² + z² = (3 + x)²
45 + z² = 9 + 6x + x²
x² + 6² = z²
45 + x² + 6² = 9 + 6x + x²
45 + x² + 36 = 9 + 6x + x²
45 + 36 - 9 = 6x
72 = 6x
x = 12
Answer:
30 minutes
Step-by-step explanation:
First you can break down the percent and the time into a fraction
You can divide it by 2
so 2%/1 (2% in 1 minute)
Then you find the amount of time it would take to paint the whole bookcase
2 * 100 = 50
So time to paint the whole bookcase would be 50
50 - 20 = 30
