2+1=3
15/3=5
split the 3 5's in ratio 2:1 and you get 10:5
Answer:
The trucking company shipped a total of 151 thousands of boxes of fruits
Step-by-step explanation:
Total boxes of fruits shipped= 151,375
How many thousands of boxes of fruit were shipped?
To find the thousands of boxes of fruits shipped, divide the total number of boxes of fruits shipped by 1000
That is
151,375 / 1000
= 151.375
Therefore, the trucking company shipped a total of 151 thousands of boxes of fruits
151,375

x^3+7^3=(x+7)(x²-7x+49) A: False (+14)
x^3+8^3=(x+8)(x²-8x+64) B:False (+8x)
x^3-10^3=(x-10)(x²+10x+100) D:False (-10x)
Lets call those two unknown numbers a, b and write the info in the problem as equations:
a*b = 30
a + b = 40
lets solve for a in the second equation and substitute in the first:
<span>a + b = 40
</span>a = 40 - b
therefore:
<span>a*b = 30
</span>(40 - b)b = 30
40b - b^2 = 30
b^2 - 40b + 30 = 0
if we apply the general quadratic equation to solve we have:
b = (40 +- √(1600 - 120))/2
b = (40 +- √(1480<span>))/2
</span>b = (40 +- 38.47)/2
There are two solutions:
<span>b1 = (40 + 38.47)/2
</span><span>b1 = 39.24
b2 = (40 - 38.47)/2
</span>b2 = 0.765
lets use the second solution <span>b2 = 0.765, and substitute in the first equation to find a:
</span><span>a*b = 30
</span>a*0.765 = 30
a = 30/0.765
a = 39.216
so the numbers are 39.216 and 0.765
