Equation: 4x + 7 = 3(2x - 5)
Step-by-step solution:
• Expand brackets
-> 4x + 7 = 6x - 15
• Move x variable to a side and the numbers to another
-> 4x - 6x = -15 - 7
• Solve
-> -2x = -22
• Multiply both sides by (-1)
-> -(-2x) = -(-22)
-> 2x = 22
• Divide both sides by 2
-> x = 22/2
-> x = 11
• Justification
-> Put x = 11 in original equation
-> 4(11) + 7 = 3( 2(11) - 5)
-> 44 + 7 = 3(22 - 5)
-> 51 = 3(17)
-> 51 = 51
-> 51 - 51 = 0
-> 0 = 0
Since both sides are equal to each other, the answer to the equation is correct.
I don't know Sam's equation so I'm not gonna answer that.
You need to see what you need to convert and how you need to convert it, do you need to divide to find out how many it goes in? Questions like that.
Answer: $889.58
Step-by-step explanation:
⇒<u>Equation:</u>
A = P(1 + rt)
Turn 3% into decimal and you get 0.03, then 9 months/ 12 months = 0.75 years.
<h2><u>
WORK ↓</u></h2>
⇒A = 870(1 + (0.03 × 0.75)) = 889.575
⇒A = $889.58
