Answer:
7kg of potatoes cost 56 R (dollars)
Step-by-step explanation:
First, we have to find the unit price of 1kg of potatoes. To do this we divide <em>24 by 3</em>. That's <em>8</em>. Each kg of potato costs 8 dollars.
Now, all we have to do is multiply <u><em>8 by 7</em></u>.
8 is the unit rate/kg and 7kg is the amount they are asking.
<u><em>8x7=56</em></u>
7kg of potatoes cost 56R
First you have to subtract 1.3 from 0.75 which equals -0.55. Then you have to add 3/7 to 2 which equals 2 and 3/7. Then you divide 2 and 3/7 by -0.55 which equals 0.9785 and that’s your answer. Sorry I don’t know the answer for the second problem but I hope this helped.
Answer:
its 32.74
Step-by-step explanation:
1. Find the Greatest Common Factor (GCF)
GCF=x
2. Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
x(2x^4/x + 5x/x) <---Fraction inside parenthesis.
3. Simplify each term in parentheses.
Answer is x(2x^3+5)
I hope this helps.
