Ethan needs to save at least $500 to purchase a new dirt bike. So far, he has saved $175. If he hopes to use two-fifths of his n

IRISSAK [1]

Answer:

$812.5

Step-by-step explanation:

Given: Ethan need to save at least $500.

He has saved so far $175

Ethan hope to use two-fifths of his next paycheck to cover the remaining amount.

Lets assume Ethan´s paycheck amount be "x"

First finding the remaining amount to be covered.

Remaining amount= $\$ 500 - \$ 175= \$ 325$

∴ The remaining amount to be covered is $325.

As given, Ethan hope to use two-fifths of his next paycheck to cover the remaining amount.

Now, using the inequality to find the amount of paycheck.

⇒ $x\times \frac{2}{5} \geq \$ 325$

multiplying both side by 5

⇒ $x\times 2\geq 325\times 5$

divinding both side 2

⇒ $x\geq \frac{1625}{2}$

∴ $x\geq \$ 812.5$

Hence, Ethan must make at least $812.5 in his paycheck to cover his remaining anount to buy dirt bike.

Please solve and show working for 13-((4/5)+(6/8))=

UNO [17]

13-((4/5)+(6/8))
Make your fractions have common denominators
13-((32/40)+(30/40))
Add your fractions and simplify
13-(62/40)
or
13-(31/20)
or
13-(1 11/20)
Then turn 13 into a fraction with a common denominator! Im going to use the second fraction method (31/20)
13 written as a fraction is 13/1, its LCD with 31/20 is 20. I now multiply the top and bottom by 20
260/20
Now I rewrite the problem again
(260/20)-(31/20)
Which equals
229/20!
This is your unsimplified answer
Finally you simplify and get
11 9/20
