A local radio station had a contest to see who could guess closest to the actual number of jellybeans that filled a small car. t
Allushta [10]
Given:
Number of jelly beens in the car: 785,000
Number of jelly beans in a bag: 800

Number of bags needed to fill the car?

785,000 / 800 = 981.25

Randall claimed = more than 981 bags
Susie claimed = exactly 981 bags.

Randall is correct. More than 981 bags.

981 x 800 = 784,800  

There is a missing 200 jelly beans if exactly 981 bags were used. Thus, a quarter of the 982nd bag is used to complete the 785,000 jelly beans.

a student showed the steps below while solving the equation 14=log5(2x-3) by graphing. which step did the student make the 1sr e
mixer [17]

Answer:

x= \frac{5^{14}+3}{2}

Step-by-step explanation:

The correct steps to solve the equation are:

14=log_5(2x-5)

5^{14}=5^{log_5(2x-3)}

Because a^{log_am}=m

So, solving we get:

5^{14}=2x-3

Sum 3 on every side:

5^{14}+3=2x-3+3\\5^{14}+3=2x

Dividing by 2 into both sides:

\frac{5^{14}+3}{2}=\frac{2x}{2}\\\frac{5^{14}+3}{2}=x

So, the answer is  x= \frac{5^{14}+3}{2}

Find the value of x in the triangle. SU RV
kodGreya [7K]

Answer:

x = 8

Step-by-step explanation:

Δ TSU and Δ TRV are similar , thus the ratios of corresponding sides are equal, that is

\frac{TS}{TR} = \frac{TU}{TV} , substitute values

\frac{x}{x+16} = \frac{5}{15} = \frac{1}{3} ( cross- multiply )

3x = x + 16 ( subtract x from both sides )

2x = 16 ( divide both sides by 2 )

x = 8

The difference of a number and -6 is less than 9 write an inequality and solve
Pavlova-9 [17]

Answer:

n - (-6) < 9

n < 3

Step-by-step explanation:

When setting up an inequality, using the key words from the problem will help.  The word 'difference' would indicate subtraction and 'less than' would be the '<' inequality sign.  Since the expression is 'the difference of a number and -6', we write:  

n - (-6) < 9

Whenever we subtract a negative number, we change both signs to positive:

n + 6 < 9

Using inverse operations to solve:  n + 6 - 6 < 9 - 6

n < 3
