Do the same thing to both sides as long as not divide by zero
PEMDAS
parenthasees
exponents (include square root)
multiplication or division
addition or subtraciton

5y/6-2y/3+5=y
interesting
isolate the variable
subtract 5 from both sides
5y/6-2y/3=y-5
subtract y from both sides
5y/6-2y/3-y=-5
try to clear fractions by multplying by greatest common multiplue of 6,3, and 1 which happens to be 6
multiply both sides by 6
5y-(2 times 2y)-6y=-30
5y-4y-6y=-30
add like terms
-5y=-30
multiply -1
5y=30
divide both sides by 5
y=6

A marathon takes place each year.In 2020 there were 6500 runners.Does this predict that in 2023 there will be more than 7500 run

777dan777 [17]

Answer:

yes

there would be 7525 runners

Step-by-step explanation:

The formula for calculating future value:

FV = P (1 + r) n

FV = Future value

P = Present value

R = interest rate

N = number of years

6500 x (1.05)^3 = 7525 runners

Wanda has three times more shirts than her brother, Will. The equation a = 3b, where a represents the number of shirts Wanda has

marusya05 [52]

Answer:

8 shirts

Step-by-step explanation:

Given the equation a = 3b, where

a = the number of shirts Wanda has

b = the number of shirts Wanda's brother (Will) has

Hence if Wanda has 24 shirts then

24 = 3b

Divide both sides by 3

24/3 = b

b = 8 shirts

Will has 8 shirts.

Jackson used the process of completing the square to solve the equation 2x2−12x=−6.

Nikolay [14]

Answer:

$x=3-\sqrt{6},x=3+\sqrt{6}$

Step-by-step explanation:

we are given equation as

$2x^2-12x=-6$

Since, we have to solve it by using complete square

so, firstly we will complete square

and then we can solve for x

step-1:

Factor 2 from both sides

$2(x^2-6x)=-3\times 2$

step-2:

Simplify it

$x^2-6x=-3$

step-3:

Add both sides 3^2

$x^2-6x+3^2=-3+3^2$

now, we can complete square

$(x-3)^2=6$

step-4:

Take sqrt both sides

$(x-3)=-\sqrt{6},(x-3)=\sqrt{6}$

step-5:

Add both sides by 3

we get

$x=3-\sqrt{6},x=3+\sqrt{6}$
