-h/3 - 17 = 25<br><br> Geometry. show all work :)

alex41 [277]

Answer:

${ \tt{ - \frac{h}{3} - 17 = 25 }} \\$

• Apply additional property of equality:

$→ \: { \tt{ - \frac{h}{ 3} = 25 + 17 }} \\ \\ → \: { \tt{ - \frac{h}{3} = 42}}$

• Apply cross multiplication, multiply either sides by -3:

$→ \: { \tt{( - \frac{h}{3} \times - 3) = 42 \times - 3 }} \\ \\ → \: { \tt{h = - 3 \times 42}} \\ \\ → \: { \underline{ \tt{ \: \: h = - 126 \: }}}$

the length of a rectagle is 5 in longer than its width. if the perimeter of the rectangle is 56 in, find its length and width

lisabon 2012 [21]

Answer:

Step-by-step explanation:

Let the width of the rectangle = x

As length is 5 inches longer than width, we have to add 5 to width

Length = x + 5

Perimeter of ractangle = 56 in

2* (length + width) = 56

2*( x + 5 + x) = 56

2* (2x + 5) = 56

Use distributive property: a*(b +c) =(a*b) + (a * c)

2*2x + 2*5 = 56

4x + 10 = 56

Subtract 10 from both sides

4x = 56- 10

4x = 46

Divide both sides by 4

x = 46/4

x = 11.5

Width = 11.5 in

length = 11.5 + 5

= 16.5 in

At Fridays football game, 1,294 tickets were sold for a total amount of $8,816.00. if each student ticket cost $5.00, and each a

e-lub [12.9K]

Answer:

512 student tickets were purchased.

Step-by-step explanation:

Represenation of the unknowns: Let s be the number of student tickets and a the number of adult tickets. Then s + a = 1294.

The dollar amounts are thus ($5/ticket)s + (8/ticket)a = $8816.

Goal: Find s; to do this, eliminate a.

Since s + a = 1294, a = 1294 - s

Then: 5s + 8(1294 - s) = 8816, or

5s - 8s + 8(1294) = 8816, or

-3s + 10352 = 8816

Isolating the 3s term, we get

-3s - 1536 = 0, or

3s = 1536, which yields s = 512

512 student tickets were purchased.
