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
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?
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.

v=1/3πr²h
2100cm³=1/3×π×r²×3r( you will insert 3r in the place of h.)
2100cm³=3π/3×r³(cancel 3 by 3)

per month. If the girls get their hair cut on a certain day, they will have exactly the same length to donate. How
long will their hair be? How long will that take?
Answer:
When they get their hair cut it will be 69 inches long. It would take 23 months for both.

A watermelon was ejected from a catapult reaching a maximum height of 20 ft. The watermelon left the catapult when it was 4 ft off the ground and hit the ground 45 ft away from the catapult. Can the equation that models the path of the watermelon be written given the information in the problem? If so, find the equation. If not, state what other information is needed.
Answer:
Step-by-step explanation:
No, the equation cannot be written with the given information. The distance from the catapult when the watermelon reached the maximum height is needed. Since the watermelon did not start on the ground, it cannot be assumed that the maximum was reached half the distance to the landing point.

Elba and Jorge each make an error in the first two steps of solving the equation. 1/2(3x+4)-8=68-6(4/3+8x) Determine the error each student made. Then, solve the equation.
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)
