Answer  x = -10

Step-by-step explanation:

 Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                     10-4*x-(50)=0 

STEP1:Pulling out like terms

 1.1     Pull out like factors :

   -40 - 4x  =   -4 • (x + 10) 

Equation at the end of step1:

STEP2:

Equations which are never true:

 2.1      Solve :    -4   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

 2.2      Solve  :    x+10 = 0 

 Subtract  10  from both sides of the equation : 

                      x = -10

One solution was found :

 x = -10

Step-by-step explanation:

Answer:

19.7 m

Step-by-step explanation:

Draw a circle to represent the ferris wheel with a 10.2 m radius. Draw a horizontal line through the circle center horizontal to the ground (at 13.1 m). Now draw a line from the center of the circle (ferris wheel) upward at 140 degrees until you reach the edge of the circle. Draw a line down from that point to the horizontal line at This is your right triangle to solve.

Hypotenuse is 10.2 m (radius of circle)

The angle of the triangle the supplementary angle of 140 degrees. 180-140=40 degrees

sin 40 degrees=rise /radius=rise/10.2

sin 40=0.6428=rise/10.2

rise=10.2(0.6428)

rise=6.6 m

13.1+6.6=19.7 m

Answer:

1.83

Step-by-step explanation:

1.78 + 5 cm

because it says she is taller so you add both

Height of Amy who is 5 cm taller than Jack is 1.83 meters.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, Jack is 1.78 m tall and Amy is 5 cm taller than Jack.

Therefore, The sum of the height of Jack and 5 cm more is the height of

Amy.

Therefore,

178 cm + 5 cm = 183 cm is the height of Amy. (1m = 100 cm)

So, 183 cm is equal to 1,83 meters.

Answer:

bB

Step-by-step explanation:

The correct equation which represents the relationship in the table is,

⇒ p = m + 160.25

Where, m, the amount of money an employee has in the morning, and p, the amount of money an employee has later in the day after they receive their paycheck.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

This table represents the relationship between m, the amount of money an employee has in the morning, and p, the amount of money an employee has later in the day after they receive their paycheck.

Hence, By all options, we can check by substitute the given values.

So, By option 3;

The equation is,

⇒ p = m + 160.25

Substitute m = 200.25,

⇒ p = 200.25 + 160.25

⇒ p = 360.50

Thus, The correct equation which represents the relationship in the table is,

⇒ p = m + 160.25

The line perpendicular to the line y=-3/4x+5 that includes the point (-3,-3) is y=-4/3x-7.

The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

The given equation of a line is y=-3/4x+5 and the coordinate point is (-3, -3)

Here, slope of a line is -3/4.

The slope of a line perpendicular to given line is m1=-1/m2

Now, the slope of a line is -4/3

Substitute m= -4/3 and (x, y) =(-3, -3) in y=mx+c, we get

-3=-4/3 (-3)+c

c=-7

Substitute m= -4/3 and c=-7 in y=mx+c, we get

y=-4/3x-7

Therefore, the line perpendicular to the line y=-3/4x+5 that includes the point (-3,-3) is y=-4/3x-7.

Answer: 4.20 gigabyte

Step-by-step explanation:

Based on the information given in the question, the equation that can be used to determine the the number of gigabytes of data Peyton can use while staying within her budget will be:

48 + 3g = 60.60

3g = 60.60 - 48

3g = 12.60

g = 12.60/3

= 4.20

The number of gigabytes of data is 4.20g

Answer:

Equation: 3g+48=60.6

Answer:

x = 7 and y = 4

Step-by-step explanation:

If QRS = MNP, then QR = MN, RS = NP and QS = MP

Given

QR = 11

QS = 15

MP = 2x + 1

Recall that QS = MP

15 = 2x+1

2x = 15-1

2x = 14

x = 14/2

x = 7

Similarly

<Q = <M

<Q + <R + <S = 180

<Q + 32 + 84 = 180

<Q + 116 = 180

<Q = 180 - 116

<Q = 64 degrees

Since <M = 17y - 4

64 = 17y - 4

17y = 64+4

17y = 68

y = 68/17

y = 4

Hence x = 7 and y = 4

Answer:

A)     [tex]m = \frac{1}{4}[/tex]

Step-by-step explanation:

Step(i):-

Given that the points are(-1,2) and (3,3)

Slope of the line

Answer:

1 foot long

Step-by-step explanation:

If this fraction is closer to one it will be close to 16/16. And since 8 is half of 16, any fraction that is around 8/16 is closer to 1/2. 15 is closer 16 so this fraction is closer to one.

The side lengths of the squares is closer to 1 foot when rounded to the nearest foot length

There are basically two rules while rounding up numbers

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down and if the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.

Non-zero digits are always significant

Zeros between non-zero digits are always significant

Leading zeros are never significant

Trailing zeros are only significant if the number contains a decimal point

Given data ,

Let the side lengths of the squares after rounding be represented as A

Now , the value of A is

The side lengths of the quilt with square shape be = 15/16 foot

Now , on rounding the value 15/16 , we get

A = 0.9375 feet

And , the value of A is much closer to 1 foot

Therefore , the value of A is 1 foot

Hence , the side lengths of the squares after rounding is 1 foot
