Step-by-step explanation:

3b/7 - 1 = 5

move the 1 over by adding

3b/7 = 6

multiply each side by 7 to get rid of the denominator

Answer:

$b=14$

Step-by-step explanation:

Step 1 : Creating the equation:

$\frac{3b}{7} -1=5$

Step 2 : Solve by adding 1 on both sides

$\frac{3b}{7}=6$

Step 3 : Mutiply both sides by 7 to get rid of the denominator

$3b=42$

Step 4 : Divide both sides by 3:

$b=14$

Step 5 : Answer:

The value of $b$ is $14$ .

Answer:

Step-by-step explanation:

1/x=x+3/2x²

By cross-multiplication, we get,

2x²=x(x+3)

2x²=x²+3x

2x²-x²-3x=0

x²-3x=0

x(x-3)=0

x=3

You work at a T-shirt printing business. Of 1,300 T-shirts shipped, 106 are imperfect. If you choose a T-shirt at random from th

Colt1911 [192]

It is given in the question that

You work at a T-shirt printing business. Of 1,300 T-shirts shipped, 106 are imperfect.

So out of 1300 T-shirts, number of perfect t-shirts are

$1300-106=1194$

So probability that the t-shirt is printed correctly is

$= \frac{1194}{1300}=0.92$

And to find the percentage, we have to multiply it by 100, and on doing so we will get 92 % .

atroni [7]

Answer:
The maximum number of children = 16

Explanation:
The greatest number of students who can get the fruit in this way (equally) will be equal to the highest common factor between the number of bananas and the number of apples.

Number of bananas = 128 = 2 * 2 * 2 * 2 * 2 * 2 * 2
number of apples = 176 = 2 * 2 * 2 * 2 *11

We can note that:
the highest common factor = 2 * 2 * 2 * 2
the highest common factor = 16

This means that the maximum number of children to get both equally is 16

Hope this helps :)

First we need to have same units before comparing them. That is, either both of them are in cm or both of them are in mm. So if we need to convert 12.5 cm to mm, we know that 1 cm =10 mm. So we have to find out how many mm are in 12.5 cm. And let 12.5 cm =x mm. So to find the value of x , we set a proportion and solve for x. That is

$\frac{1cm}{10mm}=\frac{12.5cm}{x mm}$

The units cancel out and we do cross multiplication. That is

$1*x =12.5*10$

x=125

So 12.5 cm =125 mm. Therefore the correct proportion is C.
