6 * 4x = 24x
6 * 5 = 30
3 * x = 3x
3 * 8 = 24
24x + 30 = 3x + 24 + 3
24x + 30 = 3x + 27
subtract 3x from both sides
21x + 30 = 27
subtract 30 from both sides
21x = -3
divide both sides by 21
x = -1/7
hello. your answer is -3. I just took the assignment. hope it helps.
Answer:
#3
Step-by-step explanation:
7/10
10 * 10 = 100
7 * 10 = 70
70/100
5 * .7
3.5
Between 3 and 4
Basically you know that they are 2 consecutive numbers whose product is 1980.
<span>n*(n+1)=1980 </span>
<span>n^2 + n - 1980 = 0 </span>
<span>(n -44)(n + 45)= 0 </span>
<span>n=44 </span>
<span>so the 2 page numbers is 44 and 45. </span>
<span>The faster way is just to take the square root of 1980 and since that is 44.497 you can conclude that the 2 numbers is below and above it (44, 45)</span>
