Answer:
<h2><u><em>
3.68$</em></u></h2>
Step-by-step explanation:
If 5 apples cost $1.15, find the cost of 16 apples
- we can solve with an equation
5 : 1.15 = 16 : x
x = 1.15 * 16 : 5
x = 18.04 : 5
x = <u><em>3.68</em></u>
<u><em></em></u>
check
5 : 1.15 = 16 : 3.68
4.34 = 4.34
the answer is good
Hello :
x : length y :<span> width
</span>xy = 50 ...(1)
x = 2y ...(2)
dubsct in (1) :
(2y)(y) = 50
y² = 25
y = 5
x = 10
Well, the formula is: (a-b)(a^2+ab+b^2)therefore the answer would be: (x-3)(x^2+3x+9)<span>hope this helps</span>
Answer:
1.21 * 10^25.
Step-by-step explanation:
11 *10^11 * 12 * 10^2
= 11*12 * 10^11 * 10^12
= 121 * 10^(11+12)
= 121 * 10^23
= 1.21 * 10^25.
Note: True Scientific notation is N * 10^n where 1 ≤ N < 10.
90x = 12
Divide both sides by 90
x = 0.1333....
Move the decimal to places to the right.
13.333% repeating.
