Answers

Answer 1

Answer:

x=−5/2 y+ 3/2

Step-by-step explanation:

Let's solve for x.

2x+5y=3

Step 1: Add -5y to both sides.

2x+5y+−5y=3+−5y

2x=−5y+3

Step 2: Divide both sides by 2.

2x/2

=

−5y+3

2x=

−5y+ 3/2

Answer:

x=−5/2 y+ 3/2

Answer 2

Answer:

x =4 , y = -1

Step-by-step explanation:

I used substitution method.

If the sales tax for the city of Richmond is 6%, how much tax would you pay for a Playstation 5 that costs

Round your answer to the nearest hundredths place.
Sales tax?

Answers

start by converting 6% to a decimal by dividing by 100, = 0.06

Multiply that by the cost of the PlayStation five, and that is how much tax you pay.

499.99 x 0.06 = 29.9994
The question says to round it to the nearest hundredths, so it’s $30

Which equation has the greatest rate of change?
y=12x-7
y=5x+9

y=4x+12

y=X+36

Answers

Answer:

y=12x-7

Step-by-step explanation:

b) ✓159 is not a whole number

Hey there!

The answer to your question is B.) √156

Whole numbers are numbers greater than 0 that, when changed to a fraction in its simplest form, the denominator would be 1.

The square root of a number is a whole number that, when multiplied by itself, equals the original number. Example: √4 = 2, because 2 x 2 = 4

So, we will find the square root of each of the following:

√144 = 12

√156 = 12.489996...

√169 = 13

√196 = 14

Therefore, √156 is not a whole number, because it cannot be simplified into a fraction over 1.

Answer:

Blue

Step-by-step explanation:

First, we need to find the LCD (Least common denominator)

Rewriting input as fractions if necessary:

1/10, 1/4, 1/5

For the denominators (10, 4, 5) the least common multiple (LCM) is 20.

Therefore, the least common denominator (LCD) is 20.

Now, we convert:

Red Marbles: 1/10 = 2/20

Blue Marbles: 1/4 = 5/20

Yellow Marbles: 1/5 = 4/20

As we can see, blue has the most. Now we have our answer! Good luck!
