The sum of two numbers is eight one number is four less than the other find the numbers

mash [69]

Step-by-step explanation:

the numbers : x, y

x + y = 8

x = y - 4

we use the second equation in the first :

y - 4 + y = 8

2y - 4 = 8

2y = 12

y = 6

x = y - 4 = 6 - 4 = 2

Leons older brother is 4 and 3/4 feet tall. Leon is 1/3 foot shorter than his brother .how tall is leon

Mandarinka [93]

Let

x------> height of Leon's older brother

y------> height of Leon

Convert mixed number to an improper fraction

$4\frac{3}{4}\ ft=\frac{4*4+3}{4}= \frac{19}{4}\ ft$

we know that

$x=\frac{19}{4}\ ft$ -----> equation A

$y=x-\frac{1}{3}$ -----> equation B

substitute equation A in equation B

$y=\frac{19}{4}-\frac{1}{3}=\frac{53}{12}\ ft$

Convert to mixed number

$\frac{53}{12}=\frac{48}{12}+\frac{5}{12}=4\frac{5}{12}\ ft$

therefore

<u>the answer is</u>

$4\frac{5}{12}\ ft$

6(v+2) - 7v = 6 + 5v

slava [35]

Answer:

v = 1

Step-by-step explanation:

6(v+2) - 7v = 6 + 5v

open Parentheses

6*v=6v

6*2=12

New equation:

6v + 12 - 7v = 6 + 5v

simplify

12 - v = 6 + 5v

match like terms

6 = 6v

solve

1 = v
