Hannah and Sam are working on a coding project together. Hannah has created 7x+78 lines of code, and Sam has written 6x + 73 lines of code. Hannah has written 142 more lines of code then sam. find the value of x

Answers

Answer 1

Answer:

x = 137

Step-by-step explanation:

To find the value of x you must first set up an equation to solve for x. We are told that Hannah has written 142 more lines than Sam so we can make an equation by subtracting Sam's total from Hannah's total.

(7x + 78) - (6x + 73) = 142

Hannah - Sam = Difference

We then begin to solve. First we must distribute the subtraction to all parts of Sam's equation, creating a new equation of:

7x + 78 - 6x - 73 = 142

Then put like terms together

7x - 6x + 78 - 73 = 142

7x - 6x = x

78-73 = 5

x + 5 = 142

Then isolate the x by subtracting the 5.

x + 5 (-5)= 142 (-5)

x = 137

Then plug it back into the equation to check and see if your x is correct

(7x + 78) - (6x + 73) = 142

(7(137) + 78) - (6(137) + 73) = 142

(959 + 78) - (822 + 73) = 142

(1037) - (895) = 142

Answer 2

The value of x is 137.

What is Algebra?

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Hannah has created: 7x+78 lines of code

Sam has written: 6x + 73 lines of code.

Now, Hannah has written 142 more lines of code then sam.

So, Hannah - Sam = Difference

(7x + 78) - (6x + 73) = 142

7x + 78 - 6x - 73 = 142

7x - 6x + 78 - 73 = 142

x + 5 = 142

x = 142 (-5)

x = 137

Hence, the value of x is 137.

Find the measure of angle 1

Answers

Answer:

angle 1=94 degree

Step-by-step explanation:

-x + 106=5x + 34 (they are alternate interior angles)

106-34=5x+x

72=6x

72/6=x

12=x

substitute the value of x in 5x + 34

5*12 + 34

60+34

94

Now,

angle 1 =5x +134 ( they are vertically opposite angles)

angle 1=94 degree

Answer:

ANGLE 1= -X+106

ANGLE 1= 5X+34

5X+34. =-X+106

5X+X. =106-34

6x=72

X=12

angle 1= 5x+34

=(5×12)+34

=60+34

=94

Answers

Answer:

80

Step-by-step explanation:

This is a pentagon (5 sides), n=5

The sum of internal angles equals (n-2)*180 = 540°

We have

A = 90

B = 180-40

C = 180-x

D = 180-60

E = 180-90

Sum all the angles to equal 540°

90 + 180-40 + 180-x + 180-60 + 180-90 = 540

620-x = 540

solve for x

x = 620 - 540 = 80

What is the parabola?

It's the locus of a moving point that keeps the same distance between a stationary point and a specified line. The focus is a non-movable point, while the directrix is a non-movable line.

The equation of a quadratic function, of vertex (h, k), is given by:

y = a(x – h)² + k

where a is the leading coefficient.

If the function get shifted upward, then the constant is added in the function.

If the function f(x) is f(x) = x², then the function g(x) will be g(x) = x² +11.

Then the correct option is C.

The length of the ladder that will run from the ground to the door of the tree house is nine feet. The plan recommends that the rungs of the ladder be spaced at 8-inch intervals. The first and last rung should be 6 inches from the respective ends. How many rungs will the tree house ladder have?

Answers

Answer:

13 Rungs

Step-by-step explanation:

According to the Question,

Given, The length of the ladder that will run from the ground to the door of the treehouse is 9 feet ( 9 × 12 = 108 inches).

The plan recommends that the rungs of the ladder be spaced at 8-inch intervals.

And, The first and last rung should be 6 inches from the respective ends.

Thus, the rungs Cover on 108 -(6+6) = 96 inches with 8-inch gaping between each rung.

Therefore, the Total Rungs on the treehouse ladders have (96/8)+1 ⇒ 13 Ladders.

what is the value of "m" if m% of it is 49?​

Answers

The answer is in the picture. Click on it

The value of "m" if m% of it is 49 will be 70.

What is the fundamental principle of multiplication?

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

A percentage is a minimum number or ratio that is measured by a fraction of 100.

WE need to find the value of "m" if m% of it is 49.

We have been an expression as;

m x m% = 49.

Solving further;

m x m/100 = 49.

m² / 100 = 49

Now, Cross multiplication;

m² / 100 = 49

m² = 4900

On taking square root;

m = √4900

m = 70

Therefore, the value of "m" if m% of it is 49 will be 70.
