The answer is 42
first change the numbers from scientific notations into numbers.
1.47*10^7= 14700000
3.5*10^5= 350000
now divide the number of sweets by the number of packets. the quotient is the answer
14700000/350000= 42
good luck
Answer: Isolate the variable by dividing each side by factors that don't contain the variable. x=−1/2^2
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let's organise our information :
- the function is (1/2)x²+2x+3
we want to khow the value of x that gives us : (1/2)x²+2x+3=x+7
Now the trick is to write this expression as a quadratic equation with zero at one side :
- (1/2)x²+2x+3-x-7=0
- (1/2)x²+x-4=0
Now let's solve this equation :
Δ=1²-4*(1/2)*(-4)
= 9
So we have two solutions :
So the solutions are -4 and 2
Answer:
He paid 5,000 for the old home, which was the original price of it.
And he paid 15,000 for the new home.
Step-by-step explanation
Twice the selling price of his old one, the selling price was 7,000
7,000 * 2 = 14000.
14000 + 1000 = 15000.
15,000 is three times more than he originally paid for his old home.
n Purchased a new one for 1,000 more than twice the selling price.
Answer:
In mathematics, an inverse function (or anti-function) is a function that "reverses" another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa, i.e., f(x) = y if and only if g(y) = x.
