Answer:
<em>16 million for the first year</em>
Step by step explanation:
<em>Let x be the first year's sales</em>
<em />
<em>Let x+ 3 be the second year's sales.. since they sold 3 million more in</em>
<em />
<em>the second than on the first.</em>
<em />
<em>Let 2(x+3) be the third year's sales... since they are double the second</em>
<em />
<em>year's sales.</em>
<em />
<em>Using the Distributive Property, this becomes 2x+6..</em>
<em />
<em>Now, 2x+6= 38</em>
<em />
<em>-6 -6 Subtract 6 from both sides</em>
<em />
<em>2x = 32 Divide both sides by 2</em>
<em />
<em>x= 16</em>
<em />
<em>So the sales for the first year are 16 millions, 19 on the second, and 38 on the third.</em>
Answer:
According to the laws of indices, when multiplying numbers with exponents and the bases are the same add the powers
Follow the order of operations. PEMDAS. Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction. Let's start with parenthesis. First we so everything inside the parenthesis. So the first thing we do, is exponents, 2 x 2 = 4. Now the top equation is 3 x 4 - 23. Next thing in the order of operations, is Multiplication. So now we do 3 x 4. Which equals 12. Now the top equation is 10 - 12 - 23. Now we do Subtraction in order. First 10 - 12 = negative 2 (-2) Then we do -2 - 23 which equals negative 25 (-25). Now let's work on the bottom equation. Once again follow the order of operations. We do the exponents in the parenthesis first. 10 x 10 = 100. Then do the rest in the parenthesis, 1 + 100 = 101. Now the exponents in the outside of the parenthesis. - 2 x - 2 = 4. And 5 x 5 = 25. Then we do Multiplication, 4 x 25, which equals 100. Then we do 101 - 100 = 1. Then we reduce the fraction. -25/1 = -25. Therefore the answer to your problem is -25. I apologize for taking so long to write this. Hope this helps though!
