-5a + 15/2a - 25 = 53.2 + 21.8

Answers

Answer:

a= 40

Step-by-step explanation:

-5a + 7.5a - 25 = 53.2 + 21.8

add like terms on both sides: 2.5a - 25 = 75

add 25 on both sides: 2.5a = 100

divide both sides by 2.5: a = 40

Answer:

a = 40

Step-by-step explanation:

-5a + 15/2a - 25 = 53.2 + 21.8: Add 25 to Isolate variable

-5a + 15/2a = 53.2 + 21.8 + 25: Combine Like Terms and create simmilar terms

-10/2a + 15/2a = 100: CLM again

5/2a = 100: multiply both sides by inverse of 5/2 to isolate variable

a = 40

Caelan is saving to buy a vacation home. He inherits some money from a wealthy uncle, then combines this with the $ 24162 he has already saved and doubles the total in a lucky investment. He ends up with $ 146012 , just enough to buy a cabin on the lake. How much did he inherit?

Answers

Answer:

The amount inherited is $48,844

Step-by-step explanation:

Here, we want to know the amount of money inherited by Caelan.

Let the amount be $x

From the question, the amount inherited was combined with 24,162 and doubled in an investment to give 146,012

Thus, the amount before the lucky investment will be;

x + 24,162

Thus , after doubling, the amount becomes;

2(x + 24,162)

and this equals 146,012

2(x + 24,162) = 146,012

divide both sides by 2

x + 24,162 = 73,006

x = 73,006 - 24,162

x = $48,844

What is the equation of a line parallel to -5x + y= 2 that passes through the point with coordinates (-2,1)?

Answers

Answer:

y=5x+11

Step-by-step explanation:

You can solve this with the point-slope formula: y-y1=m(x-x1). The line is parallel; both slopes are equivalent.

First we have to rewrite the original equation, which is rewritten into y=5x+2 by subtracting -5x on both sides.

Next, plug in the coordinates we have into the point-slope formula (-2, 1), along with the slope from the original equation (5). To check, we can plug the coordinates back into the equation.

y-(1)=5(x+2)

y-1=5x+10

y=5x+11

Check:

(1)=5(-2)+11

1=-10+11

g(t) = -2t + 3f(t) = 2t - 5
Find (g f)(t)

Answers

Answer:

( g − f ) ( a ) = g ( a ) − f ( a )

( g −f ) ( a ) = g ( a ) − f ( a )

= − 3 a − 3 − a 2 − 5

= − a 2 − 3a − 8

Step-by-step explanation:

After calculating, the value of (g f) (t) is ( - 4t + 13).

What is Function?

A relation between a set of inputs having one output each is called a function.

Given that;

The functions are,

⇒ g(t) = -2t + 3 and f (t) = 2t - 5

So, The value of function (g f) (t) is find as;

⇒ (g f) (t) = g (f (t))

= g (2t - 5)

= - 2 (2t - 5) + 3

= - 4t + 10 + 3

= - 4t + 13

Answer Prt B: 3x

Answer Part A: ^

The equation 3x =y models the relationship between jellyfish, and sea turtles such that the ratio of their numbers remain constant.

What is ratio?

Ratio is the relationship between two numbers given by a quotient

If the ratio of two numbers x and y is x/y then the fraction x/y gives that what parts x is of y .

Given that there are 4 sea turtle and 12 jellyfish in the sea when Alex counted the number.

Ratio of number of sea turtle to number of jellyfish = 4/12 = 1/3

Let at any time the number of sea turtles be x and number of jellyfish be y

Then ratio of number of sea turtles to jellyfish = x / y

Given that this ratio remained constant during the remainder of his dive,

∴ x/y = 1/3

Cross multiply

⇒ 3x = y

The equation that models the relationship between jellyfish, and sea turtles is 3x =y

Step-by-step explanation:

Using the tangent ratio in the right triangle.

tan35° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{opp}{100}[/tex] ( multiply both sides by 100 )

100 × tan35° = opp , that is

opp ≈ 100 × 0.7002 = 70.02

Thus height of tree = 70.02 + 5 = 75.02 ft

--------------------------------------------------------------------

Using the tangent ratio in the right triangle on the right.

tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{25.17}{rope}[/tex] ( multiply both sides by rope )

rope × tan40° = 25.17 ( divide both sides by tan40° )

rope = [tex]\frac{25.17}{tan40}[/tex] = [tex]\frac{25.17}{0.839}[/tex] = 30 ft

The emperor wanted to keep the military in constant movement during peace and prepare it for war. He also wanted to prevent his Manchu and Turkic troops from becoming infected by Chinese luxury and, further, to keep the peoples of the region in obedience.The emperor has divided the immeasurable districts beyond the Wall into forty-eight provinces and has made them all subject and tributary. Thus, he is sovereign of the Chinese and the nomads and could be justly called the greatest and mightiest ruler in the world.
