Given:5y-1/2=7 prove y=3
I am confused on the steps to get 3!

Answers

Answer 1

Answer:

y=3/2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5y+ −1/2=7

Step 2: Add 1/2 to both sides.

5y+/−1/2+1/2=7+1/2

5y=15/2

Step 3: Divide both sides by 5.

5y/5

=

15/25

y=3/2

Answer 2

The solution of the given equation is y = 3/2.

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

What are Arithmetic operations?

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operations is called the arithmetic operator.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

We have given the equation as

⇒ 5y - 1/2 = 7

Add 1/2 to both sides in the above equation.

⇒ 5y - 1/2 + 1/2 = 7 + 1/2

⇒ 5y = 15/2

Divide both sides by 5

⇒ y = 15/10

⇒ y = 3/2

Hence, the solution of the given equation is y = 3/2.

21% of the students at a High are in Maths group, 15 % are in science group, and 6 % are in both. If a student is selected randomly , what is the probability that the student is in maths or science group?

Answers

Answer:

6%

Step-by-step explanation:

The probability of picking a maths student = 21% = 21/100

The probability of picking a science student = 15% = 15/100 = 3/20

The probability of picking in both = 6/100 = 3/50

The probability that the student is in maths or science = 21/100 - 15/100 = 6/100 = 6%.

How to solve a linear equation?

A linear equation can be solved by equating the LHS and RHS of the equation following some basic rules such as by adding or subtracting the same numbers on both sides and similarly, doing division and multiplication with the same numbers.

The given equations are as below,

y = 2x + 6                               (1)

y = 6x - 10                              (2)

In order to find the variable x, equate equations (1) and (2) as follows,

2x + 6 = 6x - 10

⇒ 6x - 2x = 10 + 6

⇒ x = 4

Hence, the value of x is obtained as 4.

Answer:

x = 4 / 3  or  1.333  (Approx)

Step-by-step explanation:

Equation:

1/2(3x+4)-8=68-6(4/3+8x)

3x/2 + 4/2 - 8 = 68 - 24/3 - 48x

3x/2 + 2 - 8 = 68 - 8 - 48x

3x/2 + 48x = 66

By taking LCM

3x + 96x = 132

99x = 132

x = 132 / 99

x = 44 / 33

x = 4 / 3  or  1.333  (Approx)
