Answer:

Option D. LN=64 units

Step-by-step explanation:

step 1

Find the value of x

we know that

LN=LM+MN -----> equation A

we have

LN=12x+16

LM=10x+8

MN=5x-4

substitute the values in the equation A

12x+16=(10x+8)+(5x-4)

Solve for x

12x+16=15x+4

15x-12x=16-4

3x=12

x=4

step 2

Find the value of LN

LN=12x+16

LN=12(4)+16=64 units

The ratio of number of boys to the of girls in a school is 5:7. If there are 600 students inthe school, how many girls are there

OLga [1]

Answer:

<u>There are 350 girls in the school.</u>

Step-by-step explanation:

1. Let's review all the information provided for answering the question correctly:

Ratio of number of boys to the girls = 5:7

Number of students in the school = 600

2. How many girls are there in the school?

Number of girls = x

Number of boys = 5/7x

x + 5x/7 = 600

7x + 5x = 4,200

12x = 4,200

x = 350

<u>There are 350 girls in the school.</u>

And the number of boys is (600 - 350) = 250.

Answer:

x = 70

Step-by-step explanation:

Step 1: Simplify both sides of the equations.

$\frac{x}{10} = \frac{5x}{7}-43$
$\frac{1}{10}x=\frac{5}{7}x-43$

Step 2: Subtract 5/7x from both sides.

$\frac{1}{10}x- \frac{5}{7}x = \frac{5}{7}x - 43 - \frac{5}{7}x$
$\frac{-43}{70}x = -43$

Step 3: Multiply both sides by 70/(-43).

$\frac{-43}{70}x * \frac{70}{-43} = -43*\frac{70}{-43}$
$x = 70$

Step 4: Check if solution is correct.

$\frac{(70)}{10}=\frac{5(70)}{7} -43$
$7 = \frac{350}{7} - 43$
$7 = 50 - 43$
$7 = 7$

Therefore, x = 70.
