Answer:
They're both equal.
Step-by-step explanation:
If you simplify 36/24, its 3/2. (36 divided by 24 = 3/2.)
9/6 simplified is 3/2. (9 divided by 6 = 3/2.)
3/2 = 3/2.
<span><span><span><span>2x</span>+<span>3y</span></span>=1</span>;<span><span>x+<span>4y</span></span>=<span>−2
</span></span></span>Steps:
<span>Multiply the second equation by -2, then add the equations together.
</span><span>(<span><span><span>2x</span>+<span>3y</span></span>=1</span>)
</span><span><span>−2</span><span>(<span><span>x+<span>4y</span></span>=<span>−2</span></span>)
</span></span>Becomes:
<span><span><span>2x</span>+<span>3y</span></span>=1
</span><span><span><span>−<span>2x</span></span>−<span>8y</span></span>=4
</span>Add these equations to eliminate x:
<span><span>−<span>5y</span></span>=5
</span>Then solve<span><span>−<span>5y</span></span>=5</span>for y:
<span><span><span>−<span>5y</span></span><span>−5</span></span>=<span>5<span>−5</span></span></span>(Divide both sides by -5)
<span>y=<span>−1
</span></span>Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
<span><span><span>2x</span>+<span>3y</span></span>=1
</span>Substitute<span>−1</span>foryin<span><span><span><span>2x</span>+<span>3y</span></span>=1</span>:
</span><span><span><span>2x</span>+<span><span>(3)</span><span>(<span>−1</span>)</span></span></span>=1
</span><span><span><span>2x</span>−3</span>=1</span>(Simplify both sides of the equation)
<span><span><span><span>2x</span>−3</span>+3</span>=<span>1+3</span></span>(Add 3 to both sides)
<span><span>2x</span>=4
</span><span><span><span>2x</span>2</span>=<span>42</span></span>(Divide both sides by 2)
<span>x=2
</span>Answer:
<span><span>x=<span><span>2<span> and </span></span>y</span></span>=<span>−<span>1

hello
the answer to the question is option A
to solve a problem like this, let x represent the first number
x + (x + 1) = 17
x = first number
x + 1 = successive number
Answer:
11. D
12. C
Step-by-step explanation:
11. We need to find 2 numbers where the sum is -15 and the product is 56. Those two numbers are -7 and -8 so the answer is D.
12. Like the previous problem, we need to find 2 numbers where the sum is -9 and the product is 14. Those two numbers are -2 and -7 so the answer is C.
The 6 in 836 is in the ones place and the 6 in 863 is in the yens place
