Answer:
The first courier service cost is;
Where, x is the number of kilograms delivered;
The second courier service cost is;
Equating it, we have;
Thus, the weight that will result in equal cost is 1 kilogram.
And the cost is 5( 1 )+14 = $19
Answer: 3/4 + 7/12 - (-4) = 3/4 + 7/12 + 4 (two minuses make a plus)
3/4 + 7/12 + 4/1 = 9/12 + 7/12 + 48/12 (4 = 4/1 or 4 divided by 1)
(to add the fractions the denominators need to be the same. Multiply both the denominator and numerator by the same number)
(9+7+48)/12 = 64/12 = 5 and 1/3 or 16/3
We can also get this answer by leaving the 4 as a whole number:
9/12 + 7/12 +4 = 16/12 + 4 = 1 and 1/3 + 4 = 5 and 1/3
If you put the sum in a calclator you also get 5 and 1/3.
Hope this helps :)

Answer: y/10
Step-by-step explanation: step 1 = simplify y/100
step 2 = (5/32 x 64) x y/100
step 3 = simplify 5/32
step 4 = (5/32 x 64) x y/100
step 5 = The answer is y/10
Answer:
24.78%
Step-by-step explanation:
Initial price = $230
Final price = $287
change in price = final price - initial price
= 287 - 230
= $57
Percent change
= (change in price / initial price) x 100%
= (57 / 230) x 100%
= 24.78%
Answer:
14/19
Step-by-step explanation:
Note that there are two " - " signs here. Thus, the end result will be " + "
We move from left to right, obtaining first 10/19 divided by (5/7):
10
----- ÷ (5/7)
19
To divide by (5/7), invert (5/7) and then multiply. We get:
10 7 2(7)
----- * ----- = ------- = 14/19
19 5 19
