Which of the following is the solution set of the given equation?
(x - 3) - 2(x + 6) = -5
A) {-10}
B) {-4}
C) {8}

Answers

x= -10

first you distribute the -2 throughout (x+6) which then becomes, -2x -12
After you’ve done that plug it in the equation, the equation should be, x-3-2x-12=-5
Now combine like terms. After it should look like, -x - 15 = -5, Add 15 to both side. It should be, -x = 10
Finally divide by -1 on both sides and that should give you x= -10

would you classify the number 200 as a perfect square, a perfect cube,both, or neither? explain

Answers

A: No, the number 200 is not a perfect square.

B: No, the number 200 is not a perfect cube.

C: Yes. the number 200 is neither.

No number times itself twice or threefold is 200 therefore I can conclude it's neither.

Answer: neither because a perfect square is number like 9 or 100 where 3^2=9 and 10^2=100 and likewise for a perfect cube. 200 is not a perfect square or perfect cube for any number

Answers

Steps to solve:

-7x - 5y = -68 when x = -6

~Substitute and simplify

-7(-6) - 5y = -68

42 - 5y = -68

~Subtract 42 to both sides

-5y = -110

~Divide -5 to both sides

y = 22

How can you use unit rates to solve pricing problems?​

Answers

Answer:

a ratio is a comparison of two numbers or measurements

the objects being compared are called the terms of the ratio.

if the tow terms are different units this is called a rate.

example:

David covers 600 miles in 8 hours and John covers 380 miles in 5 hours. Who is driving faster ?

solution:

Distance covered by David in 1 hour is

=  600 / 8  

=  75 miles per hour

Distance covered by John in 1 hour is

=  380 / 5  

=  76 miles per hour

When we compare the above unit rates (Distance covered in 1 hour), John is driving faster than David.

We can use unit rates to solve pricing problems because we solve for price of one of that item.

For example, David bought 5 pounds of peanuts for $10, how much does it cost for one pound?

10 / 5 = $2 per pound

The $2 is the unit rate and we use to find if David buys more then 10 pounds.

Best of Luck!
