Iola has $75. She buys a pair of shoes on sale for one-half off and a pair of socks for $6. She has $32 left. Which equation can be used to find x, the regular price of the shoes?

Answer:

31%

Step-by-step explanation:

use the formula :

P(A&B) / P(B)

meaning :

probability that a student graduates while on fin aid / student on fin aid

= 1879/6101

=1879/6101 *100

= 30.798....

= 31%

Answer:

x = 29.8

Step-by-step explanation:

x represents the unknown number

20.7 + x = 50.5

x + 20.7 - 20.7 = 50.5 - 20.7

x = 50.5 - 20.7

x = 29.8

Answer:

16

Step-by-step explanation:

X = 16

Solution:

g(-7) = a + 2

g(-7) = -7 + 2

g(-7) = -5

Best of Luck!

g(a) = a + 2

What's the answer of the equation when a = -7.

By putting the value, we get

g(a) = a + 2

g(-7) = -7 + 2

g(-7) = -5

Answer:

-30

Step-by-step explanation:

3*-10 = -30

The negative rules are simply:

negative*negative = positive

negative*negative*negative = negative

Answer:

t=1

Step-by-step explanation:

7t-8t+4=5t-2

-1t+4=5t-2

-1t+6=5t

6=6t

1=t

Check

7t-8t+4=5t-2

7(1)-8(1)+4=5(1)-2

-1+4=5-2

Answer:

6 purses

Step-by-step explanation

1. Subtract 71 from 161 as that's how much Daniela needs to make to have 161, which is 90

2. Divide 15 by 90 as 15 is the profit, so the answer would be the amount of purses she needs to sell, then you get 6

Check

6 times 15, 90

71 + 90 = 161

Answer:

V is the variable

Step-by-step explanation:

Answer:a. v

Step-by-step explanation:

Given

Required

Identify the variable

Literary, variable means things that change in values;

Going by this definition, we have that:

3 -> This is not a variable because its value will always be 3

v -> This is a variable because its value can change once its value changes, the result of the expression will also change

- -> This is not a variable; it is an arithmetic operator to subtract

8 -> This is not a variable because its value will always be 8

Take for instance

When  

Notice that there's a difference in both results;

This is as a result of v being a variable

Step-by-step explanation:

Answer:

[tex]8i^{22}[/tex] - 1

Explanation:

It's actually quite easy to tell which simplifies to a real number without working out the problem.

[tex]i^{2}[/tex] = -1

Any imaginary number with an even exponent is simplified to a real number. If it has an odd exponent, it cannot be simplified to a real number.

Some tips for fully solving the expression:

If the exponent is divisible by 4, then don't change the sign of the coefficient. You're just multiplying it by 1 because [tex]i^{4}[/tex] = [tex](i^{2})^{2}[/tex] = [tex](-1)^{2}[/tex] = 1

If the exponent is divisible by 2, change the sign of the coefficient because you're multiplying it by -1.

Answer:

-62

Step-by-step explanation:

Step 1: Define

u = 18

x = -10

y = 8

u + xy

Step 2: Substitute

18 + -10(8)

Step 3: Evaluate

18 - 80

-62

Answer:

He is incorrect.

Step-by-step explanation:

The correct answer is 4,160.

Answer:

3. He is incorrect because he should have multiplied the exponents.

Step-by-step explanation:

6∧5 × 6∧4 = 369 Incorrect

Correct: 6∧5 = 7776

6∧4 = 1296

7776 × 1296 = 10,077,696

1. He is not correct, therefore the first answer is wrong.

2. You do not subtract the exponents unless one of the exponents is negative and you have the same bases. You have the same bases in this equation, however, neither one of them are negative. Therefore, the second answer is wrong.

3. The third answer is correct because if you were adding the two terms together then you would add the exponents together then multiply the base as many times as needed. However, since you are multiplying the two terms together, you also need to multiply the exponents together. From there, you then multiply the terms and get your answer.

4. The fourth answer is also incorrect because you need to multiply the bases together in order to get a correct answer.

I took the test on Edge

Answer:

22 ft.

Step-by-step explanation:

First we can get the total change in elevation, which should be the final elevation minus the initial elevation:

(98ft)-(10ft)=88ft

Then, to get the change in 4 equal intervals, we can divide the total change in elevation by 4.

(88/4)ft=22ft

So during each of the four intervals, assuming they were four equal intervals, the diver descends 22ft.

Answer: 28

Step-by-step explanation:

The discriminant in the quadratic equation which is

it is the part inside of the square root part

it is called the discriminant beause it tells you how many real or complex roots/solutions you will get

so b^2-4ac

convert to ax^2+bx+c=0 form

9x^2+2=10x

subtract 10x

9x^2-10x+2=0

ax^2+bx+c=0

a=9

b=-10

c=2

substitute

-10^2-4(9)(2)

100-36(2)

100-72

28

discriminant is 28
