Answer:
D-70.81
Step-by-step explanation:
I did the math, this should be correct.
Good luck!
The equation is $130 + $31.67x = 500
Subtract 130 from both sides $31.67x = $370
Divide $31.67 from both sides
X=11.68
BUT
you can’t have .68 of a day so the answer is 11 days.
Answer:
B
Step-by-step explanation:
First, we are decreasing the number so it has to be a decrease.
Next, we divide 7/31 and get around 0.23, which also represents 23 percent.
This only shows that 7 is 23 percent of 31, so we need to find the decrease by seeing the difference of 100 and 23.
We get 100 - 23 = 77, and because it is a decrease we get B.
Answer:
x=4
Step-by-step explanation:
3x-5 = 7
Add 5 to each side
3x-5+5 = 7+5
3x = 12
Divide each side by 3
3x/3 = 12/3
x = 4
Since we don't know where to start, we can always give that a variable which in this case, it's X. Since we are finding the sum of three consecutive odd numbers, we will be skipping numbers so we can add 2 each time. Now, let's set up an equation.
<h2>
X + X + 2 + X + 4 = 159</h2><h2 /><h2>
3x + 6 = 159</h2><h2>
-6 -6 ← subtract 6 on both sides</h2><h2 /><h2>
3x = 153</h2><h2>
÷3 ÷3 ← divide both sides by 3</h2><h2 /><h2>
X = 51</h2><h2>
X + 2 = 53</h2><h2>
X + 4 = 55</h2><h2 />
Therefore, the smallest of our three consecutive integers is 51.
