Answer:You have 4 quarters and 45 pennines  

Step-by-step explanation:

Step-by-step explanation:

6x - 15 = 75, 6x = 90, x = 15.

2(2x - 1) = 46, 2x - 1 = 23, x = 12.

x + (x - 10) = 26, 2x = 36, x = 18.

5x - 3x = 10, 2x = 10, x = 5.

Hence the equations

in increasing order of x-values are:

5x - 3x = 10,

2(2x - 1) = 46,

6x - 15 = 75, and

x + (x - 10) = 26.

Answer:

5x - 3x = 10

2(2x - 1) = 46

6x - 15 = 75

x+(x - 10) = 26

Answer: x = 12

Step-by-step explanation:

5(x-1)+3x=7(x+1)

5x - 5 + 3x = 7x + 7

8x - 5 = 7x + 7

x - 5 = 7

x = 12

Answer:

Francisca was supposed to divide by 1/3, instead of subtracting by 1/3.

Step-by-step explanation:

She was completing the equation correctly until she subtracted 1/3 instead of dividing both sides. It should have been 5 divided by 1/3 or 15/3 divided by 1/3.

Step-by-step explanation:

The cost of having a car towed 14 miles is $103.

To express Linda's towing cost, C, in terms of miles towed, x, we can use the given information that Little Town Auto charges a flat fee of $75 plus $2 per mile towed.

The function for the towing cost, C, can be written as:

C(x) = 75 + 2x

Where x represents the number of miles towed.

To find the cost of having a car towed 14 miles, we substitute x = 14 into the function:

C(14) = 75 + 2(14)

C(14) = 75 + 28

C(14) = 103

Therefore, the cost of having a car towed 14 miles is $103.

[tex]\huge\boxed{t=3}[/tex]

Step-by-step explanation:

[tex]-5(t+3)=-30[/tex]

[tex]-5(t+3)=-30[/tex]    divide both sides by (-5)

[tex]\dfrac{-5\!\!\!\!\diagup(t+3)}{-5\!\!\!\!\diagup}=\dfrac{-30}{-5}[/tex]

[tex]t+3=6[/tex]       subtract 3 from both sides

[tex]t+3-3=6-3\\t=3[/tex]

[tex]-5(t+3)=-30[/tex]       use the distributive property a(b + c) = ab + ac

[tex](-5)(t)+(-5)(3)=-30[/tex]

[tex]-5t-15=-30[/tex]     add 15 to both sides

Answer:

$160.75

Step-by-step explanation:

Step one:

given data

The resort charges $20.75 per hour in addition to a $35 deposit to rent a snowboard

The time spent from 8:30 am to 12:30 pm = 4hours

Step two:

Let the number of hours be and the total cost be y

Now the expression for the situation can be represented as

y= 20.75+35x

for x= 4

y=20.75+35(4)

y=20.75+140

y=160.75

Step-by-step explanation:

Multiplication comes before division. To add or subtract we can do from left to right by thousand, hundred, or any respective place value thus options (1) and  (2) are correct.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

Subtraction = Minus of any two or more numbers with each other called subtraction.

Using the PEMDAS rule,

Parenthesis = 1st

Exponents = 2nd

Multiplication = 3rd

Divide = 4th

Addition = 5th

Subtraction = 6th

Suppose an addition,

120 + 320

Now add from left to right,

100 + 300 = 400

20 + 20 = 40

Now, 400 + 40 = 440

Thus, adding from left to right is true.

Hence "Multiplication comes before division. To add or subtract we can do from left to right by thousand, hundred, or any respective place value ".

Answer:

2 or C

Step-by-step explanation:

I'm taking this to mean

4 = 2(x - 1)^2

4 = 2(x^2 - 2x + 1)

4 = 2x^2 - 4x + 2

2x^2 - 4x - 2  =  0

x^2 - 2x - 1 = 0

What you get from here is sqrt(2) as one of the roots.

That is not nearly an answer.

4 = 4(x -1)

4 = 4x - 4

8 = 4x

x = 8/4

x  =  2

That makes C the answer.

The triangles are right triangles, then we can apply Pytagoras´ theorem.

Solution is:

The triangles are similar

From the attached picture, and from parameterization concepts

RS = μ × RQ     0 < μ < 1

From Δ PRQ     sinα = RQ/PR               PQ = h₁ ( hypothenuse in Δ PRQ)

From Δ RST      sinα = RS/ST                ST = h₂ ( hypothenuse in Δ RST)

Then     RQ/h₁   = RS/h₂

or     RQ × h₂  =  RS × h₁      ⇒   h₂ = (RS/RQ) × h₁    ⇒ h₂ = μ × h₁

Then both hypothenuse are proportional, it follows both triangles are similar
