Step-by-step explanation:
2<X<4 it may help you to understand.
Answer:
No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.
Step-by-step explanation:
Small number = S
Number = N
N = 2S + 3
N = 2(S+1)
N = N
2S + 3 = 2(S + 1)
2S + 3 = 2S + 2
-2S -2S
3 = 2
No solutions
Therefore...
"No solutions exist because the situation describes two lines that have the same slope and different y-intercepts." is correct
Answer:
<em><u>x=-2</u></em>
Step-by-step explanation:
<u>Let's solve your equation step-by-step.
</u>
<em>3x+9=x+5
</em>
<u>Step 1: Subtract x from both sides.
</u>
<em>3x+9−x=x+5−x
</em>
<em>2x+9=5
</em>
<u>Step 2: Subtract 9 from both sides.
</u>
<em>2x+9−9=5−9
</em>
<em>2x=−4
</em>
<u>Step 3: Divide both sides by 2.
</u>
<em>2x
/2=-4/2</em>
<em>x=−2
</em>
Answer: 10 dimes
Solve using system of equations.
q=number of quarters and d=number of dimes
.25q+.10d=5.50 because the total of dimes and quarters is $5.50
8+d=q because there are 8 more quarters than dimes
substitute 8+d for q into the first equation to get .25(8+d)+.10d=5.50
then simplify
2+.35d=5.50
.35d=3.50
d=10 he has 10 dimes
Start with the smallest square number, it is zero but assuming they don’t want this answer so we will try with 1:
So n * 10 = 1
n= 1/10
n= 0.1
