Answer:

b = 0 and b = 4

Step-by-step explanation:

\frac{5}{3b^3-2b^2-5} = \frac{2}{b^3-2} ( cross- multiply )

2(3b³ - 2b² - 5) = 5(b³ - 2) ← distribute parenthesis on both sides

6b³ - 4b² - 10 = 5b³ - 10 ( subtract 5b³ from both sides )

b³ - 4b² - 10 = - 10 ( add 10 to both sides )

b³ - 4b² = 0 ← factor out b² from each term on the left side

b²(b - 4) = 0

equate each factor to zero and solve for b

b² = 0 ⇒ b = 0

b - 4 = 0 ⇒ b = 4

How long does a car traveling at 70 mph take to travel 88 miles, in hours
dybincka [34]
So,

Obviously, the car will travel 70 miles in one hour.  So after one hour, the car will have traveled 70 miles.  That leaves 18 miles.

The time it will take for the car to go another 18 miles will be 18 divided by 70.
\frac{18}{70}

Simplify.
\frac{2*3*3}{2*5*7}
\frac{3*3}{5*7}
\frac{9}{35}

Divide.
≈ 0.25714

So a car traveling at 70 mph will take approximately 1.25714 hours or 1.26 hours to travel 88 miles.

y = k/x
8 = 78/x
8x = 78
x = 78/8
x = 9.75

ss7ja [257]

Answer:

6.18 > 6.1

b. required more in strawberry

Step-by-step explanation:

Given that

Strawberry = 6.18 pound

Raspberry = 6.1 pound

Based on the above information

As we can see that the number of pounds in strawberry is more than the number of pounds in Rasberry

So, it would be

a. Strawberry > Rasberry

6.18 > 6.1

b.  Here the inequality means that the number of pounds is required more in Strawberry as compared to the Rasberry so that the jam could be made
