Answer: x=70
Step-by-step explanation:
Answer & Step-by-step explanation: 4.58
<em>PEMDAS:</em>
<em>Parenthesis first! (8 + 7 + 3.3) = 18.3</em>
<em>Exponents second! </em>
<em> = 1/4 = 0.25</em>
<em>Multiply third and solve! 18.3 x 0.25 = 4.575</em>
<em>Round if needed! </em><em>4.575</em><em> = </em><em>4.58</em><em> = </em><em>4.6</em><em> = </em><em>5</em>
Answer:
distance driven < 300 miles.
Step-by-step explanation:
Plan A
She needs the car for 3 days.
1 day costs 60 dollars
3 days cost 60*3 = 180 So this is the maximum amount that she can spend
Plan B
She still needs the car for 3 days
1 day costs 20 dollars of the car does not move
3 days costs 3*20 = 60 dollars.
60 + 0.4m < 180 Subtract 60
0.4m < 180 - 60
0.4m < 120 Divide by 0.4
m < 120/ 0.4
m < 300
Answer
so she should drive less than 300 miles.
Subtitute the pair (3,28) to x and y, if the result in right side is -8, then the pair is a solution to the equation
2x - y/2
= 2(3) - 28/2
= 6 - 14
= -8
The result is -8, so the pair (3,28) is a solution
