vitfil [10]
S=small pizzas
p=pasta dinners

s+p=1600

9s+13p=15600
multiply first equaiton by -9 and add to the second one

-9s-9p=-14400
<u>9s+13p=15600 +</u>
0s+4p=1200

4p=1200
divide by 4
p=300

sub back

s+p=1600
s+300=1600
minus 300 both sides
s=1300

Which of the following is a radical equation? x + StartRoot 5 EndRoot = 12 x squared = 16 3 + x StartRoot 7 EndRoot = 13 7 Start
d1i1m1o1n [39]

Answer:

x = 3

Step-by-step explanation:

(8x-8)^{3/2}=64

Multiply both sides by the exponent 2/3.

8x - 8 = 64^{2/3}

Solve for the exponent.

8x-8=16

Add 8 to both sides.

8x = 16+8

8x=24

Divide 8 into both sides.

x=24/8

x=3

Nady [450]

Answer:

The percentage increase without baggage fee=25%

The percentage increase with baggage fee=41.66%

Step-by-step explanation:

Given the cost of the airline ticket two weeks ago is $300 and The present airline ticket is $375

We know that when a quantity increases from x to y then The percentage increase is equal to \frac{y-x}{x} *100

Here the percentage increase =  \frac{375-300}{300} *100=25%

Now the airline charges an extra $50 baggage fee which means teh present value of the airline ticket is $375+$50=$425

the percentage increase =  \frac{425-300}{300} *100=41.66%
