if two angles form a linear pair and the measure of one angle is 47 degrees, what is the measure of the other angle

Answers

Step-by-step explanation:

Since we know that as the angles are in linear pair then their sum equals to 180°

Given

One angle = 47°

Let the other angle be x then

x + 47° = 180° {being linear pair }

x = 180° - 47°

Therefore x = 133°

The measure of the other angle is 133°

Hope it will help :)❤

Answer:

133°

Step-by-step explanation:

they form 180° together, so 180-47=133°

Sophie had two different coupons for the book store, 15% off coupon or the $2.50 off coupon. The store only allows you to use one coupon at time. The book she wanted was $12. Which is a better coupon for sophie to use and why

Answers

Answer:

$2.50 coupon is better as it gives a cheaper sale price.

Step-by-step explanation:

Price of good = $12

Sale price = price of good - coupon

Coupon 1 :

$2.50

Sale price = $12 - $2.50 = 9.50

Coupon 2:

15% off

Sale price =. (100 - 15)% * 12

= 0.85 * 12

Solve the system of linear equations by elimination,
-y - 10 = 6x
5x +y = -10

Answers

Hey again!

The solution to the given system is (0, -10)

To solve using elimination, we have to add the equations together, and the "y"s will cancel out, and then solve the equations:

5x - 10 = 6x - 10

Now solve.

Add "10" to both sides:

5x = 6x

Subtract "5x" from both sides

0 = x

Now, we plug in the solved "x" value in an equation to solve for "y".

5(0) + y = -10

y = -10

We now know that the solution to the given system is (0, -10)

Hope this helps! Have an amazing day, and remember, you've got this!!

The solution to the given system of linear equations is (0, -10) which is determined by the elimination method.

What is the Linear equation?

A linear equation is defined as an equation in which the highest power of the variable is always one.

The system of linear equations is given in the question:

-y - 10 = 6x    ....(i)

5x +y = -10    ....(ii)

To solve using elimination, we have to add the equations (i) and (ii) together, and the "y" will be eliminated, and then solve the equations:

⇒ 5x - 10 = 6x - 10

Add "10" to both sides of the above equation

⇒ 5x = 6x

Subtract "5x" from both sides

⇒ 0 = x

⇒  x = 0

Now, substitute the value of x = 0 in equation (ii) to solve for "y".

⇒ 5(0) + y = -10

⇒ y = -10

Therefore, the solution to the given system of linear equations is (0, -10).

14. Two sides of a parallelogram are in the ratio 5 : 3 and its perimeter is 48 cm. Find
the length of each of its sides.​

Answers

Answer :-

Given :-

Ratio of two Sides of Parallelogram ( Length and breadth) = 5 : 3

Perimeter of the parallelogram = 48cm

To Find :-

Length of each side of the parallelogram

Formula :-

Perimeter of the parallelogram = 2( length + breadth)

Solution :-

Let the length and breadth be 5x and 3x

2(5x + 3x) = 48cm

2(8x) = 48cm

x = 48/16

x = 3cm

Length = 5x = 5×3cm = 15cm

Breadth = 3x = 3×3cm = 9cm

We know that,

In parallelogram Opposite sides are equal

Hence, The sides of the Parallelogram are 15cm, 9cm, 15cm and 9cm

Two glasses of milk and 3 snack bars have a total of 63 carbohydrates​ (carbs), and 4 glasses of milk and 2 snack bars have a total of 82 carbs. Determine how many carbs are in one glass of milk and in one snack bar.

Glass of milk=15 carbs

One snack bar=11 carbs

Step-by-step explanation:

4m+6s=126

4m+2s=82

Cancel out the 4ms

6s=126

2s=82

minus top and bottom equations and remain with

4s= 44

s=44/4

s=11 ∴ one snack bar is 11 carbs

subs s=11 into equation 1

If [tex]f(x)=3(x+5)+\frac{4}{x}[/tex] we get [tex]\mathbf{f(a+2)=\frac{3a^2+27a+46}{a+2}}[/tex]

Step-by-step explanation:

We are given the function: [tex]f(x)=3(x+5)+\frac{4}{x}[/tex] we need to find the value of f(a+2)

For finding the value of f(a+2) we will put x= a+2

We have [tex]f(x)=3(x+5)+\frac{4}{x}[/tex]

Put x = a+2

[tex]f(a+2)=3(a+2+5)+\frac{4}{a+2}\\Solving:\\f(a+2)=3(a+7)+\frac{4}{a+2}\\Taking\:LCM\\f(a+2)=\frac{3(a+7)(a+2)+4}{a+2}\\f(a+2)=\frac{3(a^2+2a+7a+14)+4}{a+2}\\f(a+2)=\frac{3(a^2+9a+14)+4}{a+2}\\f(a+2)=\frac{3a^2+27a+42+4}{a+2}\\f(a+2)=\frac{3a^2+27a+46}{a+2}[/tex]
