Answer:

Step-by-step explanation:

Let,

The number be = n

According to the question, 

First 7 times of n = 7n

Sum of 10 and the number = 7n + 10

Said that,

The sum of 10 and 7 times of the number is 59.

Therefore, 

By the problem ,

=> 7n + 10 = 59

=> 7n = 59 - 10

=> 7n = 49

$= > n = \frac{49}{7}$

=> n = 7

Hence,

The required number is 7 (Ans)

10+7n=59
7n=59-10
7n=49
n=49/7
n=7

Estimate the number of school-aged children in the city where the population is approximately 60,000, if 1 of every 10 citizens

Sauron [17]

1 out of 10 are school aged.

Divide total population by 10:

60,000 / 10 = 6,000 are school aged.

Each school holds 500, divide school aged by 500:

6,000 / 500 = 12

They would need 12 schools.

A group of students attended a math club. Half the students are boys and 4/9 of the boys have brown eyes. What fraction of the g

Daniel [21]

Answer:

2/9

Step-by-step explanation:

The question asks to calculate the number of boys in a group who has brown eyes given the fraction of the boys having the brown eyes.

To do this, we can take any arbitrary value for the total number of students in the math club. Let’s say this is 360 students.

Now, we are told that half of these number are boys. The total number of boys is thus 180 boys. Also, we are made to know that 4/9 of these boys have brown eyes. This means 4/9 of 180 boys have brown eyes. This is numerically equal to 4/9 * 180 = 80 boys.

Hence, the fraction of the math club with brown eyes is 80/360 = 2/9

4^(4x-1)=32 How do I solve this problem? Do I do 4 to the fourth power first?

yKpoI14uk [10]

Answer:

$\large\boxed{x=\dfrac{7}{8}}$

Step-by-step explanation:

$4^{(4x-1)}=32\\\\(2^2)^{4x-1}=2^5\qquad\text{use}\ (a^n)^m=a^{nm}\\\\2^{2(4x-1)}=2^5\iff2(4x-1)=5\ \ \text{use the distributive property}\ a(b+c)=ab+ac\\\\(2)(4x)+(2)(-1)=5\\\\8x-2=5\qquad\text{add 2 to both sides}\\\\8x=7\qquad\text{divide both sides by 8}\\\\x=\dfrac{7}{8}$
