110 +0.70x = 50+ 0.90x

timurjin [86]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{x = 300}}}}}$

Step-by-step explanation:

$\sf{110 + 0.70x = 50 + 0.90x}$

Move 0.90x to left hand side and change it's sign

⇒ $\sf{0.70x - 0.90x + 110 = 50}$

Move 110 to right hand side and change it's sign

⇒ $\sf{0.70x - 0.90x = 50 - 110}$

Collect like terms

⇒ $\sf{ - 0.2x = 50 - 110}$

Calculate

⇒ $\sf{ - 0.2x = - 60}$

Divide both sides of the equation by -0.2

⇒ $\sf{ \frac{ - 0.2x}{ - 0.2} = \frac{ - 60}{ - 0.2} }$

Calculate

⇒ $\sf{x = 300}$

Hope I helped!

Best regards!!

Following are the solution to the given question:

Step-by-step explanation:

For question 1:

Calculating the speed between A and B:

$Time\ (t)= 1 \ hours\\\\Distance\ (d)= 10 \ km\\\\V=\frac{d}{t}=\frac{10}{1}= 10 \ kmph$

For question 2:

Calculating the speed between B and C:

$Time\ (t)= (2-1)=1 \ hours\\\\Distance\ (d)= (15-10)= 5\ km\\\\V=\frac{d}{t}=\frac{5}{1}= 5 \ kmph\\$

For question 3:

In this the speed between A and B is the double to speed between B and C.

A jar contains 6 yellow marbles, 4 black marbles, and 2 purple marbles. Two marbles are picked at random, without replacement. W

ludmilkaskok [199]

Answer:

The probability of selecting both yellow is 5/22.

Step-by-step explanation:

Given the number of yellow marbles = 6

Black marbles = 4

Purple marble = 2

Now find the total number of marbles in the jar.

Thus total marbles = Yellow marbles + Black marbles + Purples marble

Now insert the values in the above formula.

Total marbles = 6 + 4 + 2

Total marbles = 12

The probability of 2 yellow marble:

$= \frac{6}{12} \times \frac{5}{11} \\= \frac{5}{22}$

Thus, the probability of selecting both yellow is 5/22.
