For this problem your equation will be x+(x+1)+(x+2)=537

Multiply and Simplify:

x+x+1+x+2=537

3x+3=537

Subtract 3 from both sides:

3x+3-3=537-3

3x=534

Divide both sides by 3:

3x/3=537/3

x=179

179 is the middle number so: 178+179+180=537

180 is the third number.

Anyone knows the number sequence of 7,8,15,23,38?

OLga [1]

Sequence
8 - 7 = 1
15 - 8 = 7
23 - 15 = 8
38 - 23 = 15
For more sequences
38 + 23 = 61
Then
61 + 38 = 99
And so on the sequence continue

A half of a class and a half of a student got A on a test. If yet another student got an A, then two-thirds of the class would h

svlad2 [7]

Answer:

6 students.

Step-by-step explanation:

let the number of students in class be<em> x</em>

Since Half of the class represents half of the students, therefore

Number of student who got A in test = $\frac{x}{2}$

Now if one more student got A in test then the number of students who got A in test will be $\frac{x}{2} +1$

Now according to equation,

$\frac{2x}{3} = \frac{x}{2} +1$

$\frac{2x}{3} - \frac{x}{2} = 1$

Further solving

$\frac{4x-3x}{6} = 1$

$x = 6$

Hence the total number of students in class is 6.

Can someone simplify

Rashid [163]

Answer:

Option (2). $2\frac{1}{4}$

Step-by-step explanation:

The given expression is [ $-5\frac{1}{4}-(-7\frac{1}{2})$ ]

We can rewrite the fractions as,

$-5\frac{1}{4}$ = $-(5+\frac{1}{4})$

$-7\frac{1}{2}=-(7+\frac{1}{2})$

Now we will substitute the fractions in the expression,

$[-(5+\frac{1}{4})]-[-(7+\frac{1}{2})]$

= $-(5+\frac{1}{4})+(7+\frac{1}{2})$

= (-5 + 7) + $(-\frac{1}{4}+\frac{1}{2})$

= 2 + $\frac{2-1}{4}$

= 2 + $\frac{1}{4}$

= $2\frac{1}{4}$

Therefore, Option (2). will be the answer.
