Answer:
the second one four fifth times 20
Step-by-step explanation:
4/5×22.01=17.68 which is approximately equal with 4/5×20=16.
The answer is 14 because 5 multiplied by 2 is 10+4 is 14
Answer:
He had $36 in the beginning
Step-by-step explanation:
We are asked to calculate how much John has after making some series of purchases. Let’s proceed.
Now, let the initial amount of money John had be $X. Let’s keep this
He initially spends 2/3 at a bookstore, the fraction unspent is 1/3. Since x is our figure, the amount unspent is $x/3
Now, he spent 1/3 of this at a craft store. This means he didn’t spend 2/3 of this and it corresponds to $8.
This mathematically means:
2/3 * $x/3 = $8
2x/9 = $8
2x = $72
x = $72/2 = $36
Answer:
Step-by-step explanation:
Hello:
equation is the line is : y = ax+b a is a slope
y = (3/5)x+b
passing through the point (9;−4) : -4 =(3/5)(9)+b
b = - 4 -27/5 = -47/5
y = (3/5)x- 47/5
Rewrite each given equation as
where each of the last equalities follows from the change-of-base identity,
for any base <em>b</em> > 0 and <em>b</em> ≠ 1. I picked the natural base, <em>e</em>.
Then
as required.
