Hello there! 106,250 is 85% of a number, which is represented by z. To find the value of z, we can write and solve a proportion. Set it up like this:
106,250/z = 85/100
This is because 106,250 is part of a whole, and 85% is a part of 100%. Let's cross multiply the values. 106,250 * 100 is 10,625,000. 85 * z is 85z. That simplifies to 10,625,000 = 85z. Now, divide each side by 85 to isolate the z. 85z/85 cancels out. 10,625,000/85 is 125,000. There. z = 125,000.
Answer:
Initially:
Cam has X stickers.
Dan has 2x.
Dan gives Cam 15 stickers:
Cam has x + 15 stickers.
Dan has 2x - 15 stickers.
2x - 15 = (x + 15) + 22.
X = 52 stickers.
x + 15 = 52 + 15 = 67 stickers.
2x - 15 = 2*52 - 15 = 89 stickers.
Step-by-step explanation:
Aahwheheehheheheheheheheheheuww
One thousand three hundred fifty is one way
That is 22 and 21:
22 + 21 = 43
if we write equations to find them, we say, numbers are a and b, they are consecutive so:
b = a + 1
a + b = 43
we substitute one in the other equation:
a + (a + 1) = 43
2a = 42
a = 21
then
b = a + 1 = 21 + 1
b = 22
