John has a gift card of $100. He spends $5 per day. Write an equation to show the amount left on the card after x days
ch4aika [34]

Answer:

y = 100 - 5x

Step-by-step explanation:

Total amount of gift card = $100

Amount spent per day = $5

Number of days = x days

Write an equation to show the amount left on the card after x days

y = 100 - 5x

Where,

y = amount left on the gift card

x = number of days

For example,

Assume x = 2 days

Amount left on the gift card, y

y = 100 - 5x

y = 100 - 5(2)

= 100 - 10

= 90

y =$90

(1−√(5))×(2−√(5)) <br><img src="https://tex.z-dn.net/?f=%281%20%2B%204%20%5Csqrt%7B10%7D%20%29%282%20-%20%20%5Csqrt%7B10%7D%20%2

To simplify these expressions, you can either use a calculator (which I'm assuming your teacher doesn't want you to do) or FOIL (distribute).

The first one would be:

(1- \sqrt{5}) (2- \sqrt{5}) \newline =(1)(2)+(1)(- \sqrt{5} )+(- \sqrt{5})(2)+(- \sqrt{5})(- \sqrt{5}) \newline =2- \sqrt{5}-2 \sqrt{5}+5 \newline =7-3 \sqrt{5}

The second one would be:

(1+4 \sqrt{10})( 2- \sqrt{10}) \newline =(1)(2)+(1)(- \sqrt{10})+(4 \sqrt{10} )(2)  +(4 \sqrt{10})(- \sqrt{10}) \newline =2-\sqrt{10}+8 \sqrt{10} -40 \newline =-38+7 \sqrt{10}

Tom and Brian are hiking towards each other at the opposite ends of a trail that is 21 miles long. Tom hikes uphill at a speed o
Arturiano [62]

Answer:

3.5 hours

Step-by-step explanation:

Distance = 21 miles

Speed * time

Speed * time = distance

Tom speed = 2 mph

Brian = 4 mph

Let time = t

Brian distance + Tom's distance = total distance

4t + 2t = 21

6t = 21

t = 21 / 6

t = 3.5 hours
