Answer:

1. 1

2. 2

3. -3

4. 51

Step-by-step explanation:

To do this, in each input number (I will represent the number as x), you have to do the number in the input number, x. You have to divide x by 2, then add 1.

x/2 + 1 would be the answer (this is an example).

1. 1

2. 2

3. -3

Assume the total cost of a college education will be $200,000 when your child enters college in 16 years. You presently have $55

natka813 [3]

Answer:

8.4%

Step-by-step explanation:

let x = interest rate

55,000(1 + x)^16 = 200,000

divide both sides by 55,000

(1 + x)^16 = 3.636

find the invese of 16

1 + x = 1.084

x = 0.084

x = 8.4

30 Points Solve for x. 8x2−3=2 x=±10√4 x=±10√2 x=±5√2 x=±5√4

ANTONII [103]

Answer:

$x=(+/-)\frac{\sqrt{10}}{4}$

Step-by-step explanation:

we have

$8x^{2}-3=2$

adds 3 both sides

$8x^{2}=2+3$

$8x^{2}=5$

Divide by 8 both sides

$x^{2}=5/8$

square root both sides

$x=(+/-)\sqrt{\frac{5}{8}}\\ \\x=(+/-)\frac{\sqrt{5}}{2\sqrt{2}} \\ \\x=(+/-)\frac{\sqrt{10}}{4}$

The standard tip in a restaurant is 15% of the bill before tax. Many people in California find the tip by doubling the sales tax

cricket20 [7]

To answer this you could do a couple things. 1. Actually calculate both tips and then subtract them. Here is the math ( assuming it is $60, not 60% that you mean). a. 0.15 x 60 = $9. b. 0.0825 x 2 x 60=$9.90. c. 9.90-9.00= $0.90 difference.

The other strategy would be to find the difference on the percents and then multiply by $60. a. 8.25%x2=16.5%-15%. Difference of 1.5%. b. 0.015 x $60=$0.90.
