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:

length of box = 56cm

breadth = 0.4m = 40cm

height = o.25m = 25cm

Volume of Box = Volume of soap × n

n = number of soaps.

LBH = lbh × n

56 × 40 × 25 = 7 × 5 × 2.5 × n

n = 56×40×25/35×2.5

n = 56000/87.5

n = 640

so, 640 soaps can be placed in the box.

Answer:

y= x+3

Step-by-step explanation:

The equation of a line in slope form is given as :

y= mx + c ---------where m is the gradient and c is the y-intercept

Finding the slope ,

m = Δy/Δx

m= 5-3 / 2-0

m= 2/ 2

m= 1

Taking m=1, point {2,5} , an imaginary point {x,y}

1 = y-5 / x-2

1 {x-2} = y-5

x-2 = y-5

x= y-5+2

x= y-3

x+3 =y

y= x+3 -----the equation of the line in slope- intercept form

Answer:

-2y=-5x=3

Step-by-step explanation:

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

Step-by-step explanation:

The measure of ∠WYX in the given isosceles triangle is; 150°

We are told that Triangle WXY is isosceles..

We are given the base equal angles as;

YZ bisects ∠WYX and m∠XYZ = (15x)°. Thus;

∠WYX = 2(15x)° = (30x)°

Now, we are told that m∠YXZ = (2x + 5)°

Thus, since sum of angles in a triangle is 180°, then;

30x + (2x + 5)° + (2x + 5)° = 180

34x + 10 = 180

34x = 170

x = 170/34

x = 5

Thus;

∠WYX = (30x)° = (30 × 5) = 150°

Answer:

150°

Step-by-step explanation:

Triangle WXY is isosceles. ∠YWX and ∠YXW are the base angles. YZ bisects ∠WYX. m∠XYZ = (15x)°. m∠YXZ = (2x + 5)°. What is the measure of ∠WYX?

5°

75°

150°

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

The water will be 9.17 feet deep at noon.

Answer:

y= -2/5x - 6

Step-by-step explanation:

Use Rise/Run with any of the given points! You go up two, left 5. That proves the slope is -2/5. The line hits the Y axis at -6, so the y-intercept is -6!

Answer:930

Step-by-step explanation:

Answer:

930

Step-by-step explanation:

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:

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.

Answer:

  $92,400

Step-by-step explanation:

The amount in the account after t years is ...

  A = P(1+rt)

where P is the principal invested, r is the annual interest rate, and t is the number of years.

Here, the number of years is (240 months)/(12 months/year) = 20 years, so the formula tells you the amount is ...

  A = $28,000(1+0.115*20) = $28000(3.3) = $92400

The total amount in the account after 240 months is $92,400.
