Get like terms together. you might have to move across the equals sign
3x-x=-6+82
2x=76
x=38
Answer:P(2) = 2(2)³ - 2(2)²- 3
= 16 - 8 - 3
= 5
Remainder or value of P(2) = 5
Quotient = (2x³- 2x² - 3)/ x-2 = 2x² + 2x + 4
Step-by-step explanation:
Answer:
19 km/h
Step-by-step explanation:
average speed = total distance / total time
in this case it will be 57/3 = 19 km/h
Four scarves and six hats is $52.00
<span>4s+6h=52 </span>
<span>two hats is $1.00 more than the cost of one scarf. </span>
<span>2h=1s+1 </span>
<span>2h=s+1 </span>
<span>s=2h-1 </span>
<span>substitute for s </span>
<span>4s+6h=52 </span>
<span>4(2h-1)+6h=52 </span>
<span>8h-4+6h=52 </span>
<span>14h=56 </span>
<span>h=4 </span>
<span>s=2h-1 </span>
<span>s=8-1 </span>
<span>s=7 </span>
<span>a scarf cost $7 </span>
<span>a hat cost $4</span>
Answer: x = 8
Step-by-step explanation: Move all terms that don't contain x to the right side and solve.
