Answer:
Simple Division. See explanation.
Step-by-step explanation:
Simply put, 5 1/3 divided by 2 2/7 is 2.333333 (continues on forever)
This in fraction form however is 2 1/3.
Final answer: 2 1/3 in fraction form, and 2.333 in decimal.
A. Multiplied by 2 for the first then for the second multiply by three.
Explanation: the equations already have opposite signs for y so reversing the signs would be counterproductive. (Eliminates B and D) and the easiest way is to get the numbers before the Y variable to be the same. The top by 2 and bottom by 3 would do that, leaving only A.
She started off with 120 then spent 25.65 on a shirt then 4.58 on a snack
25.65 and 4.58 are the numbers that you have to add together then subtract from 120.
so 25.65+4.58=30.28
So then you subtract 30.28 from 120 and get 89.72
She has $89.72 left over
Hope I helped :)
Answer:
a) x² +1
b) x² +25
Step-by-step explanation:
a) (x+i)(x− i)
= x² - ( i ) x + ( i ) x - ( i)²
= x² - i² ∵ i² = -1
= x² - (-1)
= x² +1
b) (x+5 i)(x− 5i)
= x² - ( 5 i ) x + ( 5 i ) x - ( 5 i)²
= x² - 25 i² ∵ i² = -1
= x² - 25(-1)
= x² +25
we can also solve
using identity
(a + b)(a - b) = a² - b²
= (x+5 i)(x− 5i)
= x² - (5 i)²
= x² - 25 i²
= x² +25
