Lyles height is twice the difference of the height of his brother, harry, and the height of his dad, vince. Lyle is 2 1/2 feet t

Greeley [361]

Answer:

$5 = 19 - 4v$

Step-by-step explanation:

We are given the following in the question:

$\text{Lyle's height} = 2( \text{Harry's height - Vince's height})$

Let l be Lyle's height, h be Harry's height and v be Vince's height.

Thus, we can write:

$l = 2(h-v)$

Lyle's Height =

$2\dfrac{1}{2}\text{ feet}$

Harry's height =

$4\dfrac{3}{4}\text{ feet}$

Putting the value in the equation:

$2\dfrac{1}{2} = 2(4\dfrac{3}{4}- v)\\\\\dfrac{5}{2} = \dfrac{19}{2} - 2v\\\\5 = 19 - 4v\\4v = 19-5\\\\v = \dfrac{14}{4}\\\\v = 3\dfrac{2}{4} = 3\dfrac{1}{2}$

Thus, Vince's height is 3.5 feet.

there are 6 girls in a music class. this represents 3/7 of the entire class. solve 3/7s=6 to find the number of students,s, in t

iVinArrow [24]

The number of students in the class is $s=14$

Explanation:

It is given that there are 6 girls in a music class.

This represents $\frac{3}{7}$ of the entire class.

To determine the number of students in the class, we need to solve the equation $\frac{3}{7}s=6$

Let us solve the expression for s.

Multiplying both sides of the equation by $\frac{7}{3}$ , we have,

$(\frac{7}{3} )\frac{3}{7}s=6(\frac{7}{3} )$

Simplifying the expression, we have,

$s=\frac{42}{3}$

Dividing by 3, we have,

$s=14$

Thus, the number of students in the class are 14.
