Answer:

6 titles and 16 acts were elaborated

Step-by-step explanation:

Let the number of titles be t and the number of acts be a

Since the total is 22 operations:

a + t = 22 •••••••(i)

Total amount from titles = 3500 * t = 3500t

Total amount from acts = 2000 * a = 2000a

2000a + 3500t = 53,000 ••••••(ii)

From i, a = 22-t

Insert this in ii

2000(22-t) + 3500t = 53,000

44,000 - 2000t + 3500t = 53,000

1,500t = 53000-44000

1500t = 9000

t = 9000/1500

t = 6

But a = 22 -

= 22-6 = 16

Marat540 [252]
<h2>Answer:</h2><h2>The correct option is d. (i) and (ii)</h2>

Step-by-step explanation:

The total miles covered per day = 45

No of commuting days in a week = 5

Total miles in a week = 45 * 5 = 225

The total amount spent on gasoline = $ 38

Cost of gasoline per gallon = $ 2.48

The number of gallons consumed per week = \frac{38}{2.48} = 15.32 gallons of gasoline per week.

This confirms (ii) statement

The amount spend on gasoline per mile = \frac{38}{225} = $0.17

This confirms (i) statement

The number of miles per gallon of gasoline = \frac{225}{15.32} = 14.68 miles

The statement (iii) is false.

Lapatulllka [165]

Answer:

H= 121.25 meters

Step-by-step explanation:

To find the value of H after 30 months given the equation H=0.20x+115.25,

replace x by 30 in the equation and solve;

H=(0.20*30)+115.25

H=6+115.25

H= 121.25 meters

Therefore, the height will be 121.25 meters

alexdok [17]

Step-by-step explanation:

We distribute first:

(9.5*a)+(9.5*4)= 9.5a+38

We can subtract the a from 9.5a.

9.5a-a=8.5a

The answer is 8.5a+38

I'm so sorry if i'm wrong!
