<u>Answer:</u>

It will take 2 hours 36 minutes for the two trains to meet.

<u>Step-by-step explanation:</u>

The distance between the two trains is decreasing by 95+115= 210miles per hour, which can be written as \frac{210 miles}{1 hour}.

So at this rate, the distance between the trains will be reduced to zero in:

\frac{546 miles}{\frac{210 miles}{1 hour} } = 476 miles * \frac{1 hour}{210 miles}

= \frac{546}{210} = 2.6 hours

Changing 2.6 hours to hours and minutes:

2 hours + 0.6 hours = 2 hours + (0.6 * 60) = 2 hours + 36 minutes

Therefore, it will take 2 hours 36 minutes for the two trains to meet.

Cesar has 32 boxes of pasta and 48 jars of sauce that he will be putting into bags for a food drive. He wants each bag to have the same amount of pasta and sauce and wants to use all of the items. Use the drop-down menus to complete the statements below about the number of bags Cesar can make.

What is the greatest number of bags Cesar can make and Each bag would have _____ pasta and _____ jars of sauce

Answer:

The greatest number of bags Cesar can make is 16 bags.

Each bag would have 2 pasta and 3 of jars of sauce

Step-by-step explanation:

We solve the above question using Greatest Common Factor method

The factors of 32 are: 1, 2, 4, 8, 16, 32

The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48

Then the greatest common factor is 16.

Hence, the greatest number of bags Cesar can make is 16 bags.

For Pasta, We have 32 pasta

Each bag would have: 32/16

= 2 pasta

For Jars of sauce, we have 48 jars of sauce.= 48/16

= 3 jars of sauce

What is 5x+538/23*1000-500=?
Leokris [45]

Answer:

x = (-105300)/23

Step-by-step explanation:

Solve for x:

5 x + 526500/23 = 0

Hint: | Put the fractions in 5 x + 526500/23 over a common denominator.

Put each term in 5 x + 526500/23 over the common denominator 23: 5 x + 526500/23 = (115 x)/23 + 526500/23:

(115 x)/23 + 526500/23 = 0

Hint: | Combine (115 x)/23 + 526500/23 into a single fraction.

(115 x)/23 + 526500/23 = (115 x + 526500)/23:

(115 x + 526500)/23 = 0

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of (115 x + 526500)/23 = 0 by 23:

(23 (115 x + 526500))/23 = 23×0

Hint: | Cancel common terms in the numerator and denominator of (23 (115 x + 526500))/23.

(23 (115 x + 526500))/23 = 23/23×(115 x + 526500) = 115 x + 526500:

115 x + 526500 = 23×0

Hint: | Any number times zero is zero.

0×23 = 0:

115 x + 526500 = 0

Hint: | Isolate terms with x to the left hand side.

Subtract 526500 from both sides:

115 x + (526500 - 526500) = -526500

Hint: | Look for the difference of two identical terms.

526500 - 526500 = 0:

115 x = -526500

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 115 x = -526500 by 115:

(115 x)/115 = (-526500)/115

Hint: | Any nonzero number divided by itself is one.

115/115 = 1:

x = (-526500)/115

Hint: | In (-526500)/115, the numbers 526500 in the numerator and 115 in the denominator have gcd greater than one.

The gcd of 526500 and 115 is 5, so (-526500)/115 = (-(5×105300))/(5×23) = 5/5×(-105300)/23 = (-105300)/23:

Answer: x = (-105300)/23
