QUESTION POSTED AT 18/01/2020 - 07:23 AM

Let x be the number of times that Michael rode on the roller coaster and let y be the number of times that he rode on the boat, then:
x + y = 10 [because he went on the two rides a total of 10 times], and
4x + 3y = 37 [because a ride on a roller coaster costs 4 tickets and the boat ride costs 3 tickets and he spent a total of 37 tickets]
From the first equation, 4x + 4y = 40
subtracting the second equation from the third equation gives: y = 3, and from the first equation x = 10 - y = 10 - 3 = 7
Therefore, Michael rode on the roller coaster 7 times and on the boat 3 times.

If the variable is the same you can combine it

**Answer: Third option is correct.**

**Step-by-step explanation:**

Since we have given that

Charges for a 3 hour service call on Monday = $94

Charges for a 5 hour service call on Tuesday = $130

So, our coordinates will be (3,94) and (5,130)

As we know the** "Two point form":**

Now, we need the charges for 2 hour service call.

Let x = 2 hours

We get that

Charges for 2 hour service = $76.

**Hence, Third option is correct.**

All the numbers in this range can be written as with and . Construct a table like so (see attached; apparently the environment for constructing tables isn't supported on this site...)

so that each entry in the table corresponds to the sum of the tens digit (row) and the ones digit (column). Now, you want to find the numbers whose digits add to perfect squares, which occurs when the sum of the digits is either of 1, 4, 9, or 16. You'll notice that this happens along some diagonals.

For each number that occupies an entire diagonal in the table, it's easy to see that that number shows up times in the table, so there is one instance of 1, four of 4, and nine of 9. Meanwhile, 16 shows up only twice due to the constraints of the table.

So there are 16 instances of two digit numbers between 10 and 92 whose digits add to perfect squares.

X = k/y

4 = k/10

k = 4 x 10 = 40

Thus, x = 40 / y

90 = 40 / y

y = 40/90 = 4/9

4 = k/10

k = 4 x 10 = 40

Thus, x = 40 / y

90 = 40 / y

y = 40/90 = 4/9

**Answer:**

The equation is ; The value of *x* is **4.2ft**.

**Step-by-step explanation:**

A ratio is like a *constant* that remains between two values, and we can use it to find whatever others that keep the same constant relation between them.

Hank wants a dog run that keeps a constant relation between length to the width. That is, the *length* must be **2.5** times to the *width* ( ).

So, knowing that ratio or constant, we can represent it as follows:

**[ 1 ]**

But, it also could be expressed as the relation between the width to the length:

**[ 2 ]**

He wants a lenght of **10.5***ft for building a dog run for his dog*, and that this new value must keep the ratio just explained **[ 1 ] **to the width expected.

So, the equation is:

And we have to find the value for *x *that solve this equation.

However, we can use an easier way to represent this using the equation [ 2 ] for solving *x *:

That is, the width must be **4.2ft** to keep the ratio *length to the width* 5:2 ( or the ratio *width to the length* 2:5).

**Answer:**

1. 52° + x° + 67° = 180°

2. x° + 22° = 90°

**Step-by-step explanation:**

**1**. In the first figure,

Since the angles given are **supplementary angles **i.e. their sum is 180°

So, we get,

52° + x° + 67° = 180°

i.e. x° = 180° - 119°

i.e. x° = 61°

**Thus, the expression to find the value of x is 52° + x° + 67° = 180°.**

**2**. In the second figure,

Since the angles given are **complementary angles **i.e. their sum is 90°

This gives us,

x° + 22° = 90°

i.e. x° = 90° - 22°

i.e. x° = 68°

**Hence, the expression to find the value of x is x° + 22° = 90°**

Answer:

The total tax rate for each plan is computed below:

Plan A= [5%(10000)]+[10%(85000)]+[(15%(3000)]

Plan A= $9450

For Plan B, tax is computed at 10% across all earnings

Plan B= 10%x(98000)

Plan B= $9800

Difference = Plan B-Plan A=($9800-$9450)

= $350

From the computed tax rate in each plan. Plan B will pay $350 more than Plan A.

8y= -16

y = -16/8

y = -2

Substitute the value in 1st equation,

8x + 2(-2) = 4

8x = 4 + 4

**Answer:**

** The value of z is 13.**

**Step-by-step explanation:**

Given: Equation 3z + 5 = 4z − 8

We have to solve for z.

Consider the given equation

3z + 5 = 4z − 8

Subtract 3z both sides, we have,

3z -3z + 5 = 4z − 8 -3z

Simplify, we have,

5 = z − 8

Now, add 8 both side, we have,

5 + 8 = z - 8 + 8

Simplify, we get,

13 = z

**Thus, The value of z is 13.**

**Answer:**

f(x) = (x + 10)(x + 1)(x – 3)(x – 4)

**Step-by-step explanation:**

If the roots are -10. -1, 3, and 4 then look for factors (x+10)(x+1)(x-3)(x-4) since factors have the opposite sign of the root. This means

f(x) = (x – 10)(x – 1)(x + 3)(x + 4)

f(x) = x(x – 10)(x – 1)(x + 3)(x + 4)

are NOT solutions.

Lowest degree means no extra variables are added. This means

f(x) = x(x + 10)(x + 1)(x – 3)(x – 4)

is NOT a solution,

The solution is f(x) = (x + 10)(x + 1)(x – 3)(x – 4).
