7+3/5b=7/10b what is b

Mathematics

Answer:

b = 70

Step-by-step explanation:

7+3/5b=7/10b

Subtract 3/5 b from each side

7+3/5b - 3/5 b=7/10b - 3/5 b

7 = 7/10 b - 3/5 b

We need to get a common denominator or 10 on the right hand side

7 = 7/10 b -3/5 *2/2 b

7 = 7/10b - 6/10 b

7 = 1/10 b

Multiply each side by 10

7*10 = 1/10 * 10 b

70 = b

The sum of two numbers is 36 and the difference is 10. What are the numbers

Lady bird [3.3K]

Answer:

The 2 numbers are 13 and 23

Step-by-step explanation:

If 2 numbers are x and y we have:-

x + y = 36

x - y = 10

Adding:-

2x = 46

x = 23

So y = 36 - 23 = 13

3.(8 points)Consider the following experiment:Experiment: A bag contains 3 red balls, 4 blue balls, 4 green balls and 3yellow ba

MakcuM [25]

Answer:

3 / 91

Step-by-step explanation:

Given :

Red balls = 3

Blue balls = 4

Green balls = 4

Yellow balls = 3

Total number of balls = (3+4+4+3) = 14

Sample space :

RR, BB, GG, YY, RB, BR, BG, GB, YG, GY, YR, RY, BY, YB, GR, RG

Probability of drawing two red balls without replacement :

1st draw :

P(red) = number of red balls / total number of balls

P(red) = 3/14

2nd draw :

P(red) = 2 / 13

Hence,

P(RR) = 3/14 * 2/13 = 6 / 182 = 3 / 91

Convert the angle \theta=\dfrac{8\pi}{9}θ=

Olegator [25]

Answer:

160°

Step-by-step explanation:

-Given the angle in radians as $\theta=\dfrac{8\pi}{9}\ rad$

-We know that $1 \ rad=\frac{180}{\pi}\textdegree$

-Let our angle theta be X

#We therefore equate and cross multiply:

$1\ rad=\frac{180}{\pi}\\\\\frac{8\pi}{9}=x\\\\\therefore X=\frac{180}{\pi}\times \frac{8\pi}{9}\\\\=160\textdegree$

Hence, angle θ is 160°
