What is the value of 9 (n+2) — 5n for n = 1/4? A. 3 B. 9 C. 10 D. 19

2 answers:

5 0

Sure! Let's go through this.
First, we can simply plug 1/4 in for n
9(1/4+2)-5(1/4)
Then, we can use the distributive property and simplify.
9/4+18-5/4
We can combine the 9/4 and -5/4 to get
4/4+18
We notice 4/4=1, so we have
1+18
Which gets us our final answer of 19.
Hope this helps!

What is the reason for each strip on the solution of the equation?

Pani-rosa [81]

Step 1: Given

Step 2: Distributive Property

Step 3: Addition Property of Equality

Step 4: Division Property of Equality

Step-by-step explanation:

We need to match the reason with the correct step in the equation.

Equation:

Given:

$2x = -4(x-3)$

Applying Distributive property a(b+c)=ab+ac

$2x=-4x+12$

Now, Applying addition property of equality:

Adding +4x on both sides

$2x+4x=-4x+12+4x\\6x=12$

Now, Applying Division property of Equality:

Divide both sides by 6:

$\frac{6x}{6}=\frac{12}{6}\\x=2$

So, Answer will be:

Step 1: Given

Step 2: Distributive Property

Step 3: Addition Property of Equality

Step 4: Division Property of Equality

Kate's father is 32 years older than Kate is. In 5 years, he will be five times older. How old is Kate?

Sedbober [7]

In 5 years, the ratio of their ages will be 5:1, so the difference in their ages will be 4 ratio units. Those 4 units correspond to 32 years, so each unit corresponds to 32/4 = 8 years.

Thus, in 5 years, Kate will be 8 and her father will be 40. Right now, Kate is ...

... 8 - 5 = 3 years old.

_____

<em>Using equations</em>

Let k represent Kate's current age. Then in 5 years Kate will be k+5, and we will have ...

... 5(k+5) = (k+5)+32 . . the relationship betewen their ages in 5 years

... 5k +25 = k +37 . . . . eliminate parentheses

... 4k = 12 . . . . . . . . . . . add -25-k

... k = 3 . . . . . . . . . . . . . divide by 4

Kate is 3 years old.
