Helpp I'm
struggling on both of these questions !! I'm in my last questions!!​

Answer:

[tex]-\frac{39}{4}a + \frac{52}{5}[/tex]

Step-by-step explanation:

[tex]-\frac{60}{6}a + \frac{84}{8} + \frac{1}{4}a - \frac{1}{10}[/tex]

= [tex]-\frac{120}{12}a + \frac{3}{12}a + \frac{420}{40} - \frac{4}{40}[/tex]

= [tex]-\frac{117}{12}a + \frac{416}{40}[/tex]

= [tex]-\frac{39}{4}a + \frac{52}{5}[/tex]

I hope this helps!! ^-^

Answer:

the ending balance is $531.51

Step-by-step explanation:

The computation of the ending balance is shown below:

= Opening balance + all deposits - all withdrawls

= $500 + $100 + $250 + $300 - $400.32 - $100 - $55.55 - $62.62

= $531.51

hence, the ending balance is $531.51

Answer:

He has 42 more minutes to drive and 44 miles to cover to arrive at the university

Step-by-step explanation:

If he drives 63 miles in 1 hr

he would drive 107 miles in

107/ 63 = 1.7 hours

to convert 0.7 to time, multiply by 60 = 42 minutes

his total travel time is 1 hr 42 minutes

He has 42 more minutes to drive and 44 miles to drive

Answer:

98 m

Step-by-step explanation:

A 1/2 is the same as 0.5 and % means out of a 100

[tex] \frac{24.5}{100} \times 400 \\ = 98[/tex]

Answer:

98

Step-by-step explanation:

24.5% = 0.245

400 x 0.245 = 98

Answer:

Aksohia has $146 and Komley has $106

Step-by-step explanation:

The computation of the amount does each one have is shown below:

Let us assume Akoshia money be x

And, komley money be y

x>y

x - 20 = y + 20

x - y = 40

x = 40 + y.........(i)

2(y - 22) = x + 22

2y - 44 = x + 22

Now put the value of x in the above equation

2y - 44 = 40 + y + 22

2y - 44 = 62 + y

y = 62 + 44

= 106

And, x = 40 + 106

= 146

Answer:

It would be 4n -  12.

Answer:

x=34

Step-by-step explanation:

Answer: 44

Step-by-step explanation:

88/2 = 44

Answer:

44 because 50% of 88 is 44

Step-by-step explanation:

88 / 100 * 50

0.88 * 50

44

or in this case when it is 50% just do:

88 / 2

Answer:

f=-552 /343 or 5=1 and 209/343

Step-by-step explanation:

Answer:

x = 1

Step-by-step explanation:

From ΔABC and ΔDEF,

m∠C = m∠F [Given]

AC = DF [Given]

BC = EF [Given]

Therefore, ΔABC ≅ ΔDEF [By SAS property of congruence]

AB = DE [CPCTC]

2x - 1 = 5x - 4

5x - 2x = 4 - 1

3x = 3

x = 1

Answer:

35 times, or D

Step-by-step explanation:

A bag contains 5 red marbles, 6 blue marbles, 3 green marbles, 4 black marbles, and 2 yellow marbles. A marble will be drawn from the bag and replaced 100 times. What is a reasonable prediction for the number of times a green or black marble will be drawn?

A quick lesson on probability:

The probability of an event is: (the number of ways what you want can happen) / (total number of outcomes possible). For example, in a coin flip, there is 1 way to get heads, and 2 possible outcomes. Thus, the possiblity  of flipping a coin and getting heads is:

(1 way to get heads) / (2 possible outcomes) = 1/2

Then, if we were to flip the coin 100 times, we would expect about 1/2 of the times to be heads, so we should expect heads 50 times.  

On to the problem.

There are 3 green marbles and 4 black marbles, so there are 7 ways to draw a green or black marble.

Then, there are 5 + 6 + 3 + 4 + 2 = 20 possible outcomes.

Using the formula to find the probability, substitute the values we just found.

(the number of ways what you want can happen) / (total number of outcomes possible) =

(7 ways to draw a green or black marble) / (20 marbles that can be drawn) = 7/20 chance of getting a green or black marble.

Then, because there is a 7/20 chance of getting what we want, and there are 100 draws, we can say that an we should get green or black

7/20 * 100 = 35 times, or D

Answer:

1/2

Step-by-step explanation:

6 - 4(0) = 6 (incorrect answer)

6 - 4(1/2) = 4 (correct answer)

6 - 4(2) = -2 (incorrect answer)

6 - 4(4) = -10 (incorrect answer)
