Need help with 73, 74, 75, & 76. Find the value of X.
bija089 [108]

Answer:

see explanation

Step-by-step explanation:

73.

18 = 3x\sqrt{3} (divide both sides by 3 )

6 = x\sqrt{3} ( multiply both sides by \sqrt{3} )

6\sqrt{3} = 3x [ \sqrt{3} × \sqrt{3} = 3 ]

divide both sides by 3

x = 2\sqrt{3}

74.

24 = 2x\sqrt{2} ( divide both sides by 2 )

12 = x\sqrt{2} ( multiply both sides by \sqrt{2} )

12\sqrt{2} = 2x ( divide both sides by 2 )

x = 6\sqrt{2}

75.

9\sqrt{2} × x = 18\sqrt{2} ( divide both sides by 9\sqrt{2} )

x = 2

76.

2 = x × \frac{4}{\sqrt{3} } ( multiply both sides by \sqrt{3} )

2\sqrt{3} = 4x ( divide both sides by 4 )

x = \frac{\sqrt{3} }{2}

Help!! Find the value of x.
Rainbow [258]

Answer:

x = -10

Step-by-step explanation:

x + 75 + x + 125 = 180

2x + 200 = 180

2x = -20

x = -10

(In this problem a negative number is okay because the end value will be a whole number still.)

I=prt,for p please show step by step for this variable
Bond [772]

Answer:

p = \dfrac{I}{rt}

Step-by-step explanation:

I = prt

Switch sides.

prt = I

We are solving for p. We want p alone on the left side. p is being multiplied by r and t, so we divide both sides by r and t.

\dfrac{prt}{rt} = \dfrac{I}{rt}

p = \dfrac{I}{rt}

A slug travels 3 centimeters in 3 seconds. A snail travels 6 centimeters in 6 seconds Both travel at constant speeds. Mai says,
Mashutka [201]

Answer:

No I dont agree with Mai. As both the slug and snail are moving with constant speed.

Step-by-step explanation:

Given that:

A slug travels 3 centimeters in 3 seconds.

Speed of slug = distance/ time = 3/3 = 1 cms^-1

A slug travels 3 centimeters in 3 seconds.

Speed of snail = distance/ time = 6/6 = 1 cms^-1

Hence both have constant speeds only the time span for snail is increased which gives more distance it doesn't means that it had covered more distance.

i hope it will help you!
