Find the Perimeters of the rectangle whale<br>degonal is 5cm and lenght is 4cm

amid [387]

Answer:

Step-by-step explanation:

First, we have to get the breadth value.

By the pythagoras theoreom,

Diagonal²=length² + breadth²

breadth = √( Diagonal²- length²)

breadth = √( 5² - 4²)

breadth = √9

breadth= 3

Perimeter of a rectangle = 2x ( length + breadth)

= 2 x ( 4 + 3)

= 2 x 7

= 14

-7x + 6x + 8 = x - 10<br> Solve for x pls

Art [367]

-x + 8 = x - 10
8 - x = x - 10
8 = x - 10 + x
8 = 2x - 10
8 + 10 = 2x
18 = 2x
18/2 = x
9 = x
x = 9

Solve for x in this equation: 3/4+ |5-x| = 13/4

Rom4ik [11]

Answer:

x = 2.5 or 7.5

Step-by-step explanation:

Subtract 3/4.

|5 -x| = 10/4 = 2.5

This resolves to two equations:

5 -x = 2.5 ⇒ x = 5 -2.5 = 2.5
5 -x = -2.5 ⇒ x = 5 +2.5 = 7.5

The solutions are x = 2.5 or 7.5.

Cara and John collect baseball cards.Cara has 12 times as many baseball cards as John.Together they have 117 cards.How many card

enyata [817]

Answer:

Cara:108

Step-by-step explanation:

John: x number of cards

Cara: 12 times x number of cards(she has 12 times more cards than John)

Cara+John=117 cards

$12 \times x + x = 117 \\ 13x = 117 \\ x = \frac{117}{13} \\ x = 9$

Cara has 12×9 cards, so she has 108 cards.

Hope this was helpful :)
