Solve for X

Answers

Answer:

x = 44

Step-by-step explanation:

These angles are supplementary so that means they add up to 180:

47 + 3x + 1 = 180

3x + 48 = 180

3x = 180 - 48

3x = 132

x = 44

47 + 3x + 1 = 180
48 + 3x = 180
3x = 132
x= 44

What is 4x + 10 = -26

Answers

Answer:

x = -9

Step-by-step explanation:

I'm assuming you're looking for X.

So first, you'll want to subtract 10 from both sides of the equation.

4x + 10 = -26

    - 10  |  -10

4x = -36

Then from there, you'll want to divide by 4. This allows us to get x by itself.

4x = -36

/4  |   /4

x = -9

The value of 'x' is -9 in the given equation.

To solve the equation 4x + 10 = -26, follow these steps:

Step 1: Isolate the variable term by subtracting 10 from both sides of the equation.

4x + 10 - 10 = -26 - 10

4x = -36

Step 2: Solve for 'x' by dividing both sides of the equation by 4.

4x / 4 = -36 / 4

x = -9

So, the value of 'x' is -9.

Write an equation to model the statement the product of – 8 and (y + 3) is 32.
How you can use the equation to reason about the value of y?

PLS HELP! I WILL GIVE BRANLY

Answers

Answer:

-8*(y+3)=32

Step-by-step explanation:

y+3=32/-8

y=32/-8 -3

y = -7

The equation to model the statement is -8(y + 3) = 32 and the value of y is -7.

What is an Equation?

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given statement is  the product of – 8 and (y + 3) is 32.

Product means the operation is multiplication.

So the equation can be written as,

-8 (y + 3) = 32

Dividing both sides by 8,

-(y + 3) = 4

y + 3 = -4

y = -4 - 3 = -7

Hence the value of y is -7.

The data set shows the individual scoring totals for the players on the losing team in the 2012 NBA Finals.

The median is 7.5
The lower quartile is 1.5
The upper quartile is 14.5

Answer:

Median: 7.5

Lower Quartile: 1

Upper Quartile: 12.5

Step-by-step explanation:

First, arrange the numbers in numerical order.

0,0,1,2,3,7,8,11,13,16,27,32

Now find the middle of the data set, which is 7.5, because you add the 2 middle numbers (7 and 8) and then divide by 2. So your median is 7.5

Now you need to find the medians of the upper and lower quartiles. Spilt the data set into thirds.

(0,0,1,2),(3,7,8,11),(13,16,27,32)

Now find the medians.

For the lower quartile, the median is 1. For the upper quartile, the median is 12.5 .

What is pythagoraean theorem?

The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the square of the other two sides.

Here Samantha is travelling in a right-angled triangular path so the distance between Samantha's school and her friend's home will be calculated as:-

H² = P²+B²

(30)² = x²+(18)²

x²= 900-324=576

x=√576

x=24 KM

Hence the distance travelled by Samantha from her friend's home to school will be 24 KM

Answer:

c. 384 square feet

Step-by-step explanation:

First, you must find the total area of the pool and deck combined. Because the deck is 4 feet wide and it wraps around the entire pool, 8 feet can be added to both the length and the width of the pool to get the measurements of the whole rectangle combined.

25+8=33

15+8=23

To get the total area you multiply 33 by 23

33 x 23= 759

Then you get the area of the pool alone by multiplying 15 by 25

15 x 25= 375

Then you subtract the area of the pool from the total area to get the area of the deck

759-375=384
