Correct answer is A.

$3x + 2y = 8
\\2x + 3y = 2 
\\
\\9x+6y=24
\\-4x-6y=-4
\\
\\5x=20
\\x=4$

A number has the same digit in its hundreds place and its hundredths place.

Answer:

One is 2 0's before the decimal point (100) and the other is 2 decimal places AFTER the decimal point (0.01)

Essentially, the question is asking us how many times do we multiply 0.01 to get 100? This will be how many times greater 100 is compared to 0.01

Lets move the decimal point 4 times to the right:

0.01

00.1

1.0

10.0

100.0

Hello there! :)

Answer:

$\boxed{b>8}\checkmark$

<h2>*****The answer should have a GREATER THAN SIGN AND POSITIVE TOO!*****</h2>

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

PEMDAS

Order of operations

Parenthesis

Exponent

Multiply

Divide

Add

Subtract

Left/Right

First, you add by 4 from both sides of an equation.

$b-4+4>4+4$

Then, you add numbers from left/right.

4+4=8

$\boxed{b>8}$ , which is our final answer.

Hope this helps you!

Have a nice day! :)

A line has a slope of 3 and a y-intercept of 5. What is its equation in slope-intercept form? Write your answer using integers,

s344n2d4d5 [400]

Answer:

$y=3x+5$

Step-by-step explanation:

The problem is asking for slope-intercept form, luckily, they gave us both of those things.

Slope-intercept form: $y=mx+b$ , where $m=$ slope and $b=$ y-intercept.

So,

$y=3x+5$

Hope this helps!
