How many solutions does this equation have?
7a + 5 (a + 3) = 8a + 4 (a + 2)

Answers

Answer 1

Answer:

[tex]no \: solution[/tex]

Step-by-step explanation:

1) Expand.

[tex]7a + 5a + 15 = 8a + 4a+ 8[/tex]

2) Simplify 7a + 5a + 15 to 12a + 15.

[tex]12a + 15 = 8a + 4a+ 8[/tex]

3) Simplify 8a + 4a + 8 to 12a + 8.

[tex]12a + 15 = 12a + 8[/tex]

4) Cancle 12a from both sides.

[tex]15 = 8[/tex]

5) Since 15 = 8 is false, there's no solution.

[tex]no \: solution[/tex]

Therefor, this equation has no solution.

HELP Asap please!!!!!

Answers

Answer:

x should be 55

Step-by-step explanation:

the acute angle is 55 and we know that the whole horizontal is 180 so calculate 180-55 to find the obtuse angle which is 125. Then subtract 70 from that to isolate for x and you get 55.

They are a linear pair so they equal 180 so 55+70=125 and 180-125=55 so x= 55

Step 2: Subtract 6x from both sides.

18x−72−6x=6x+12−6x

12x−72=12

Step 3: Add 72 to both sides.

12x−72+72=12+72

12x=84

Given that ℓ1∥ℓ2 and the measure of ∠c = 44°, find the measures of angles a and b.
m∠a =
°
m∠b =
°

Answers

Answer:

<a = 44 degrees

<b = 136degrees

Step-by-step explanation:

From the given diagram;

<a = <c (alternate interior angle)

Since <c = 44 degrees, hence <a = 44 degrees

Also the sum of a and b is supplementary hence;

a + b = 180

44 + b = 180

b = 180 - 44

b = 136degrees

Hence m<b =136degrees

The country of Sylvania has decided to reduce the number of its illiterate citizens by 3/5 each year. This year there are 9000 illiterate people in the country.

Write a function that gives the number of illiterate people in Sylvania, P(t), t years from today

Answers

Answer:

P(t)= 9000(0.4)^t

Step-by-step explanation:

Generally, we have an exponential function as follows;

P(t)= I(1 - r)^t

This case represents a decay ( decrease in value)

from what we have;

I represents the initial value, whereas r is the rate of change

From the question, we have that the change rate is the fraction 3/5

Writing this as a decimal, it is 0.6

substituting this back into the equation, we have;

P(t)= I(1-0.6)^t

P(t)= I(0.4)^t

I in this case is 9,000

So we have it that;

P(t) = 9000(0.4)^t
