How does number 3 work, I don’t understand how it end up being x+8

Answer:

52:49

Step-by-step explanation:

pink:green

The ratio of pink to green marbles is

3k:4k

He removes 5 green marbles and adds 8 pink marbles.

Now the ratio of pink to green marbles is

(3k + 8):(4k - 5)

This rario is equal to 29:23.

(3k + 8)/(4k - 5) = 29/23

29(4k - 5) = 23(3k + 8)

116k - 145 = 69k + 184

47k = 329

k = 7

Original amounts:

3 * k = 3 * 7 = 21 pink

4 * k = 4 * 7 = 28 green

Original total = 21 + 28 = 49

Amounts after replacement:

3k + 8 = 3(7) + 8 = 29 pink

4k - 5 = 4(7) - 5 = 23 green

Total after replacement = 23 + 29 = 52

Answer: The ratio of the total number of marbles in the jar after replacement to the total number of marbles in the jar originally is 52:49.

Answer:

0.04

Step-by-step explanation:

We know that 4% of packages are lost in the mail, but we want to know the decimal.

We must convert 4% to a decimal. There are 2 ways to do this.

1.

Remove percent sign and divide by 100.

4%

4

4/100

0.04

2.

Remove percent sign and move decimal place two spots to the left.

4%

4 = 4.0

4.0  -->  0.4  --> 0.04

0.04 of the packages are lost in the mail.

Answer:

x=1.4

Step-by-step explanation:

Write the equation

[tex]\frac{5.6}{x} =4[/tex]

Multiply both sides by x

[tex]5.6=4x[/tex]

Divide both sides by 4

[tex]1.4=x[/tex]

The value of x is 1.4 when z = 4.0 and y = 5.6.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

Operators which let do a basic mathematical calculations.

+ Addition operation: Adds values on either side of the operator.

For example 12 + 2 = 14

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 12 -2 = 10

* Multiplication operation: Multiplies values on either side of the operator

For example 12*2 = 24

Given the equation as:

z = y/x

z = 4.0 and y = 5.6

To determine the value of x

⇒ z = y/x

Multiply by x on both sides

⇒ xz = y

Substitute the values z = 4.0 and y = 5.6

⇒ x(4) =(5.6)

Divide both sides by 4

⇒ x = (5.6)/(4)

⇒ x = 1.4

Hence, the value of x is 1.4 when z = 4.0 and y = 5.6.

Answer: x=2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(−2x−4)−2x+2=−42

(5)(−2x)+(5)(−4)+−2x+2=−42(Distribute)

−10x+−20+−2x+2=−42

(−10x+−2x)+(−20+2)=−42(Combine Like Terms)

−12x+−18=−42

−12x−18=−42

Step 2: Add 18 to both sides.

−12x−18+18=−42+18

−12x=−24

Step 3: Divide both sides by -12.

-12x/-12=-24/-12

Answer:

[tex]x=120^o[/tex]

in order: 60, 60, 120, 120  (all of them in degrees)

Step-by-step explanation:

We need to add all four angles given (I'll use 0.5 instead of 1/2 to make the addition easier to type):

0.5 x + 0.5 x + x + x = 360

3 x = 360

x = 360/3 = 120

Therefore,  [tex]x=120^o[/tex]

now the angles are:

two of them are 1/2 of x, that is: 120/2 = 60

Then smallest angles are: [tex]60^o \,\,\,and \,\,\,60^o[/tex]

the largest are directly equal to "x", that is: [tex]120^o\,\,\,and \,\,\,120^o[/tex]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the question:

Raina has a fabric of area 7912 centimetre square find the largest square that can be cut from it how much piece will be left

Area of fabric = 7912 cm²

Largest square that can be cut from it :

Taking the square root of 7912

Sqrt(7912) = 88.94 cm

Hence, it can be deduced that the largest square tht can be cut from it will be 88cm

From area of a square = a²

Where area is the length of the side (since all sides are equal)

a² = 88² = 7744cm²

Hence, area left = (7912 - 7744) cm² = 168 cm²

Step-by-step explanation:

6-10.75= -4.75

-4.75-2.625= -7.375

Answer:

12.

Step-by-step explanation:

This equation seems to want you to use the Order of Operations, a.k.a PEMDAS (which stands for Parentheses, Exponents, Multiplication, Division, Addition, Subtraction). When you do a problem like this, you use the Order of Operations to figure out the order in which you'd solve your problem.

You would first solve what is in parentheses, since that is the first letter in PEMDAS. 18-6x2 is what we have in our parentheses, but it's too confusing to be solved yet. The next letter is E, a.k.a exponents, but there are no exponents in this equation, so we move on. Next is M, Multiplication. We would multiply 6 by 2, which gives us 12. Moving on, we have D, Division. We would do 36/6, which is 6.

Our 5th letter is A, Addition. We would have to add our 6 to (18-12), but that couldn't work, since our 18-12 is still in parentheses, and those come first. So, we would skip to the last letter, S, Subtraction. 18-12=6, and since we solved all the problems in the parentheses, we remove them, and add both 6's together, giving us 12.

Answer:

[tex] \frac{3}{4} [/tex]

Step-by-step explanation:

Given:

Interval, [0, 4]

Required:

Average range of change over [0, 4]

SOLUTION:

Find f(0) and f(4) from the graph:

[tex] f(0) = 0 [/tex] (when x = 0, y = 0)

[tex] f(4) = 3 [/tex] (when x = 4, y = 3)

Average rate of change = [tex] \frac{f(b) - f(a)}{b - a} [/tex]

Where,

[tex] a = 0, f(a) = 0 [/tex]

[tex] b = 4, f(b) = 3 [/tex]

Plug in the values into the formula for average rate of change.

[tex] = \frac{3 - 0}{4 - 0} [/tex]

[tex] = \frac{3}{4} [/tex]

Average rate of change [tex] = \frac{3}{4} [/tex]

Answer:

Equation is [tex]8M + 7P = 131[/tex]

[tex]M = \$12[/tex]

Step-by-step explanation:

Given

Jason: 6 Movies and 4 popcorn

Michael: 2 Movies and 3 Popcorn

1 Popcorn = $5

Total = $131

Required

- Write an equation to solve

Represent Movie with M and Popcorn with P

For Jason, we have:

6M + 4P

For Michael, we have:

2M + 3P

Add these parameters together

Jason + Michael = $131

[tex]6M + 4P + 2M + 3P = 131[/tex]

Collect Like Terms

[tex]6M + 2M+ 4P + 3P = 131[/tex]

[tex]8M + 7P = 131[/tex]

Hence the equation is [tex]8M + 7P = 131[/tex]

From the question, we have that

[tex]P = \$5[/tex]

Substitute 5 for P

[tex]8M + 7 * 5 = 131[/tex]

[tex]8M + 35 = 131[/tex]

Solve for M

[tex]8M = 131 -35[/tex]

[tex]8M = 96[/tex]

[tex]M = \frac{96}{8}[/tex]

[tex]M = \$12[/tex]
