Emily is thinking of a number, which she calls n. She finds 1/4 of the number and then subtracts 3.

Debora [2.8K]

Answer:

n/4 - 3 OR 1/4n - 3

Step-by-step explanation:

First, let's assign a variable to Emily's number. Let is be <em>x</em>.

Now all we have to do is go through the problem step by step.

"She finds 1/4 of the number..."

There are two ways you can do this. You can either multiply n by 1/4 (1/4n), or you can divide by 4 (dividing by four is the same as finding 1/4 of a number). For this example let's divide by four

n/4

"...and then subtracts 3."

All we have to do is subtract 3 from n/4

n/4 - 3

REMEMBER: like I said, there are two possible options. You can either have n/4 or 1/4n. They mean the same thing

11. angle MLN and angle JLK are complementary, m angle MLN=7x-1 and m angle JLK=4x+3 . a. Solve for x b. Find m angle MLN and m

Natali [406]

a. Solve for x

Since angle MLN and angle JKL are complementary, the value of x = 8

Since angle MLN and angle JKL are complementary, their sum equal 90°.

Since angle MLN = 7x - 1 and angle JKL = 4x + 3, we have that

7x - 1 + 4x + 3 = 90

Collecting like terms, we have

7x + 4x - 1 + 3 = 90

Simplifying, we have

11x + 2 = 90

Subtracting 2 from both sides, we have

11x = 90 - 2

11x = 88

Dividing through by 11, we have

x = 88/11

x = 8

So, Since angle MLN and angle JKL are complementary, the value of x = 8

b. Find m angle MLN and m angle JKL .

Since angle MLN=7x-1 and angle JLK=4x+3 thus, angle MLN = 55° and angle JKL = 35°

Since angle MLN = 7x - 1 and x = 8, we have

angle MLN = 7x - 1

angle MLN = 7(8) - 1

angle MLN = 56 - 1

angle MLN = 55°

Since angle JKL = 4x + 3 and x = 8, we have

angle JKL = 4x + 3

angle JKL = 4(8) + 3

angle JKL = 32 + 3

angle JKL = 35°

So, Since angle MLN=7x-1 and angle JLK=4x+3 thus, angle MLN = 55° and angle JKL = 35°

Please help parts b and c

zimovet [89]

Answer:

a = 2

b = 4

c = 8

Step-by-step explanation:

Remember the relationship:

$(a^{x})^{y} = a^{x*y}$

First, in "a" we have:

a) $8^{1/3} = \sqrt[3]{8} = 2$

then in the next ones, we can use the result that we obtained in the part a:

b) $8^{2/3} = (8^{1/3})^2 = (2)^2 = 4$

Now we can do exactly the same in c:

c) where first we need to know that:

2*2*2*2 = 4*4 = 16

then:

2^4 = 16

then:

$\sqrt[4]{16} = 16^{1/4} = 2$

Now let's solve the problem:

$16^{3/4} = (16^{1/4})^3 = (2)^3 = 2*2*2 = 8$

1. What is the value of x?

polet [3.4K]

Answer:

x = 24

Step-by-step explanation:

26^2 = x^2 + 10^2

x^2 = 26^2 - 10^2 = 676 - 100 = 576

x = 24
