Answer:

y=3-x

Step-by-step explanation:

Answer:

First we get y on one side by itself.

5x+5y=15

We move x over to the other side.

5x-5x+5y=15-5x

Simplify.

5y=15-5x

Now we remove the coefficient from y.

5y/5=(15-5x)/5

Simplify.

y=15/5-5x/5

y=3-x

The answer is y=3-x

Answer:

[tex]x \approx 24\degree [/tex]

Step-by-step explanation:

In triangle BAC, by Pythagoras theorem:

[tex]AC^2 = BC^2 -BA^2 [/tex]

[tex]AC^2 = (15)^2 -(9)^2 [/tex]

[tex]AC^2 = 225 - 81[/tex]

[tex]AC^2 = 144[/tex]

[tex]AC = \sqrt {144} [/tex]

[tex]AC = 12\: cm [/tex]

In triangle ABD,

[tex] \tan \angle ABD =\frac{AD}{AB} [/tex]

[tex] \tan \angle ABD =\frac{5}{9} [/tex]

[tex] \angle ABD =\tan^{-1}\frac{5}{9} [/tex]

[tex] \angle ABD =29.054604099\degree [/tex]

[tex] \angle ABD =29.05\degree [/tex]

Next, in triangle ABC, by sine rule:

[tex] \frac{\sin \angle ABC}{AC}=\frac{\sin \angle BAC}{BC}[/tex]

[tex] \frac{\sin (\angle ABD+\angle DBC) }{12}=\frac{\sin 90\degree}{15}[/tex]

[tex] \frac{\sin (29.05\degree+x) }{12}=\frac{1}{15}[/tex]

[tex] \sin (29.05\degree+x) =\frac{12}{15}[/tex]

[tex]29.05\degree+x = \sin^{-1}\frac{12}{15}[/tex]

[tex]29.05\degree+x =53.130102354\degree [/tex]

[tex]29.05\degree+x =53.13\degree [/tex]

[tex]x =53.13\degree- 29.05\degree[/tex]

[tex]x =24.08\degree [/tex]

[tex]x \approx 24\degree [/tex]

Answer:

r = radius of circle

Step-by-step explanation:

The circumference of a circle is given by :

C = 2πr

Where

r is the radius of the circle

In this problem, we need to say that what does r represents in the given formula. It means we can say that r stands for the radius of the circle.

Answer:

Ali 25

Beth 15

Clare 32

Step-by-step explanation:

Here, we want to get the score of the three

let Ali’s score be x

He scored 10

more than Beth; Beth score will be x-10

Let us now work with the ratio

x/x-10 = 5/3

3x = 5(x-10)

3x = 5x - 50

5x-3x = 50

2x = 50

x =

50/2

x = 25

Beth will

score 25-10 = 15

score had 7 more than Ali,

25 + 7 = 32

Answer:

x = 9

Step-by-step explanation:

Since we know that the triangle is a right triangle we also know that the angle would be 90 degrees

However we are only given 56 and 3x+7

Let 3x+7 be u

We know that 56+u=90 so solve for u

u=90-56

u = 34

Now u = 3x + 7 so,

3x + 7 = 34

solve for x,

3x=34-7

3x=27

x=27/3

x=9.

Answer: $22.50

Step-by-step explanation:

The interest will be gotten by using the formula:

= PRT

= Principal × Rate × Time

= 400 × 7.5% × 9/12

= 400 × 0.075 × 0.75

= $22.50

The interest is $22.50

Answer:

its 60

Step-by-step explanation:

if its right caan i get a brainliest

Answer:

60

Step-by-step explanation:

To get the area of a right triangle (a triangle with an angle of 90 [represented by the box in the corner]) you have the formula of

Area = (a*b) divided by 2

a = one side of the triangle

b = another side of the triangle

Neither side are the hypotenuse.

Answer:

1056 inches

Step-by-step explanation:

Given that :

Initial measurement = 2358 in

Guage level after 5 days of rain (final reading) = 3414 in

Change in water level rise :

Final reading - Initial reading

(3414 - 2358) in

= 1056 inches

Answer:

A(t)= 18000(0.988)^t

Step-by-step explanation:

Given data

Ryan bought a brand new car for $18,000

Its value depreciated at a rate of 1.2%

Let us use the compound expression

A= P(1-r)^t

substitute

A= 18000(1-0.012)^t

A(t)= 18000(0.988)^t

Hence the expression is A(t)= 18000(0.988)^t

A function to represent the value of the car as a function of time is v(t) = 18000(0.988)^t

The standard exponential equation is in the form y = ab^x

b is the rate which can be growth or decline

If Ryan bought a brand new car for $18,000 and its value depreciated at a rate of 1.2%, the exponential equation represented by this statement is;t

v(t) = 18000(1-0.0012)^t

v(t) = 18000(0.988)^t

Hence a function to represent the value of the car as a function of time is v(t) = 18000(0.988)^t
