Spencer took $21 with him to the mall. At the music store he spent 2/3 of his money on a DVD. Then spent 1/4 on a drink. How much money does spencer have left?

Answers

Answer 1

Answer: After the music store he had $14 left, because 21:3=7 and 7x2 equals 14.

After the drink, he has $3.5 left, because 14:4=3.5 and 3.5x1=3.5.

Conclusion: that is one expensive drink. (Answer is 3 dollars and 50 cents. Hope this helped:)

Answer 2

Answer: Ok to solve this problem we need to first find how much he spend in the mall. We put the 2 fractions into like denominators which is 12. If we convert it we get a total of 11/12. So he spent 11/12 of his money. One way you can solve is by figuring out how much 11/12 is and subtract that by 21. Then you will get 19.25
21 minus 19.25 is 1.75 dollars. Another way is to just find out how much is 1/12 of 21. Then you will get $1.75. So Spencer has 1.75 dollars left. I hope this helps!

Answer:

Option: C is the correct answer.

C. y=|x+4|-2

Step-by-step explanation:

We know that the vertex of a absolute value function or a modulus function f(x) of the type:

f(x)=a|x-h|+k

is denoted by V such that:

V=(h,k)

By looking at the graph of the function we see that the vertex of the function is:

(-4,-2)

y=|x+4|+2

The vertex of this function is:

(-4,2)

Hence, option: A is incorrect.

y=|x-4|+2

The vertex of this function is: (4,-2).

Hence, option: B is incorrect.

y=|x-4|-2

The vertex of this modulus function is: (4,-2)

Hence, option: D is incorrect.

y=|x+4|-2

The vertex of this function is: (-4,-2)

Also, we see that the graph of this function matches the given graph.

Hence, option: C is correct.

Answer:

Step-by-step explanation:

y=|x+4|-2

What the differences between the inequality shaded circles and unshaded circles

Answers

The difference between the inequality shaded and unshaded circles is that the shaded means the answer can be either equal to or greater than/less than the number, and the unshaded circle means that the answer can be greater than/less than the number. I hope this helps!

What is the solution to the equation? 2(x – 7) = 10x + 18

Answers

x equals negative 4 ( x=-4)

1. Expand2x−14=10x+18
2. Subtract 2x from both sides−14=10x+18−2x
3 Simplify 10x+18−2x to 8x+18−14=8x+18
4. Subtract 18 from both sides−14−18=8x
5. Simplify −14−18 to −32−32=8x
6. Divide both sides by 8−328 = x
7. Simplify 328 to 4−4 = x−4 = x
8. Switch sidesx = −4

Explain when you know you need to rename a mixed Number to subtract.

Answers

You know that you need to rename a mixed Number to subtract when the numbers involved have different denominators. In such a case, the lowest common multiple (LCM) of the denominators must be calculated and subsequently used to adequately rename the mixed numbers before subtraction can be done.
