Answer:
1. y = 10 - x
Step-by-step explanation:
Because he starts off with 10 dollars, and x is the amount he spends on an item, y is showing the change that he would get from paying with a 10 dollar bill, so it's what's left over from that 10 dollars.
Its greater by a factor of 2^2 ( = 4)
Its 4 times the area of the original square.
Step-by-step explanation:
The question missing attachment (incomplete)
But the question said how far up does the ladder reach on the building?
See the attachment
Let the tita be 60° and the height of the building be 50 meters
Now
Opposite/hypotenuse = sin(tita)
50/x = sin60°
Cross multiply to find x
x = 50/sin(60°)
x= 50/0.8660
x=57.7 meters
Answer:
If u add the number it will show u te answer which is 7
Step-by-step explanation:
Ok, to solve an algebraic equation we need to get the unknown by itself on one side of the equals sign. To do that, basically we just have to cancel everything else out... but whatever we do to cancel out what we don't want, we also have to do on the other side of the equals sign...
3x + 1/10 = x - 1/7
Let's start by getting the x on the right over to the left side. To cancel it from the right side we have to subtract it (x-x = 0). Don't forget to subtract it on the left also.
3x -x + 1/10 = x - x - 1/7
Now combine like terms
2x + 1/10 = -1/7
Now let's bring the 1/10 over to the right of the equals sign to get x by itself by subtracting it.
2x + 1/10 - 1/10 = -1/7 - 1/10
Combine like terms
2x = -1/7 - 1/10
Let's get a common denominator so we can combine the fractions
2x = -10/70 - 7/70
2x = -17/70
Now divide both sides by 2 to finish getting x by itself. To divide fractions, multiply the reciprocal.
x = -17/70 x 1/2
x = -17/140
