Solve the value of x

Answer:

x = 1

y = 10

Step-by-step explanation:

5x + y = 15

Step 1: Move 5x on the other side by subtracting it from both sides

y = 15 - 5x

2x + y = 12

Step 2: Move 2x on the other side by subtracting it from both sides

y = 12 - 2x

Since y = y, that means 15 - 5x = 12 - 2x

Step 3: Add 5x to both sides

15 = 12 + 3x

Step 4: Subtract 12 from both sides

3 = 3x

Step 5: Divide both sides by 3

x = 1

y = 12 - 2x

Step 6: Plug in 1 for x

y = 12 - 2(1)

Step 7: Multiply 2 by 1

y = 12 - 2

Step 8: Subtract 2 from 12

y = 10

Answer:

  The y-intercept is 0,-13 or y is -13

Step-by-step explanation:

I don't belive that you should use the method I use, but here it is.

times -2/5 by -15 and get 6 since its a negative slope it goes down 6 since it is also going forward on the axis leading to -7 minus 6 and getting -13.

Step-by-step explanation:

Make sure every variable is on one side of the equation and you get the answer.

Answer:

Step-by-step explanation:

Simplifying

0.35x + -4.8 < 5.2 + -0.9x

Reorder the terms:

-4.8 + 0.35x < 5.2 + -0.9x

Solving

-4.8 + 0.35x < 5.2 + -0.9x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '0.9x' to each side of the equation.

-4.8 + 0.35x + 0.9x < 5.2 + -0.9x + 0.9x

Combine like terms: 0.35x + 0.9x < 1.25x

-4.8 + 1.25x < 5.2 + -0.9x + 0.9x

Combine like terms: -0.9x + 0.9x < 0.0

-4.8 + 1.25x < 5.2 + 0.0

-4.8 + 1.25x < 5.2

Add '4.8' to each side of the equation.

-4.8 + 4.8 + 1.25x < 5.2 + 4.8

Combine like terms: -4.8 + 4.8 < 0.0

0.0 + 1.25x < 5.2 + 4.8

1.25x < 5.2 + 4.8

Combine like terms: 5.2 + 4.8 < 10

1.25x < 10

Divide each side by '1.25'.

x < 8

Simplifying

x < 8

Answer:

200+200+1,000+6,000 = 7,400 - 1,200 = 6,200

6,000+200=6,200

Step-by-step explanation:

so 200 plus 200 equal to 400 plus 1,000 equal to 1,400 plus 6,000 equal to 7,400 and then 7,400 subtract by 1,200 equal to 6,200.

and 6,000 plus 200 equal to 6,200.

Hope this helps! :)

Step-by-step explanation:

Since 2 is the common factor, 2 goes into 4, 2 times; 2 goes into 6, 3 times

Answer:

A. 30 inches

B. 11 pieces

Step-by-step explanation:

Piece 1 = 120 inches

Piece 2 = 210 inches

1. He wants the smallest pieces to be as long as possible without having any leftover, how long should each piece be?

Find the highest common factor of 120 and 210

120: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120.

210: 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210.

The highest common factor of 120 and 210 = 30

Therefore, the smallest and longest pieces should be cut into 30 inches each

B. Total Smaller pieces of wood = piece 1 / 30 + piece 2 / 30

= 120/30 + 210/30

= 4 + 7

= 11 pieces

Answer:

4/5

Answer:

2.75

Step-by-step explanation:

The  decimal is halfway between 2.7 and 2.8 is 2.75

Suppose that the number is abcd.efg and belongs to the decimal numerical system.

Remember one thing that the place on the left of decimal point is called ones. Move one-one places to right, and divide by 10 and 10 more and more.

Move one-one places to left, and multiply (un-divide) by 10 and 10 more and more.

Thus, we write abcd.efg as:

[tex]a \times 10^3 + b \times 10^2 + c \times 10^1 + d \times 10^{0} + e \times 10^{-1} + f \times 10^{-2} + g \times 10^{-3}[/tex]

We will call d as ones digit, c as tens digit (it get multiplied by 10), b as hundreds digit etc.

We call e as digit at 10th place (division by 10), f as digit at hundredth place and so on.

Given;

Two decimal numbers;  2.7 and 2.8

Mid point=a+b/2

=2.7+2.8/2

=5.5/2

=2.75

Therefore, the mid value in decimal will be 2.75

Step-by-step explanation:

Answer:930

Step-by-step explanation:

Answer:

930

Step-by-step explanation:

Answer:

x=0

x=1

The table already give us a hint, which is a set of values that are telling us what is the value of every function f(x) and g(x) for a given value for 'x' variable.

From the table we know that f(x) decreases when x>0 and goes in the other direction when x<0.

g(x) goes on a different direction, when x>0, it gets bigger, and when x<0, the function decreases.

So the two functions do not have too much space for being equal.

So, you can use the points given in the table to start your test.

f(0)= 0,25 ^ 0=1 since a number raised to 0 is always 0.

g(0)=-0.75 * 0 + 1 = 1

f(1)=0.25^1=0.25 since a number raised to 1 is always equals to itself

g(1)=-0.75*1+1=0.25

So f(x)=g(x), when x=1 and when x=0

Answer:

  9.17 ft

Step-by-step explanation:

Put x=12 in the equation and evaluate. (The sine argument is in degrees.)

  y = 1.5·sin(25.72(12 +1.5)) +9.5 = 1.5·sin(347.22) +9.5

  y = -0.33 +9.5 = 9.17
