The answer to the given **expression **is 2

To "solve" or "isolate" a **variable** is to place it on its own side of the equation.

All other variables or **constants** should be moved to the opposite side of the equation using inverse operations. The operations must be applied to both sides of the equation in order to maintain the equation's balance.

Given : x = 5 and y = 7

To find : [tex]\frac{y^{2} - x }{y + 3x}[/tex]

When we substitute the values mentioned above in this above expression we get;

[tex]\frac{7^{2}- 5 }{ 7+ 3X5}[/tex]

⇒ [tex]\frac{49 - 5}{ 7 + 15}[/tex]

⇒ [tex]\frac{44}{22}[/tex]

On dividing it with 22 we get

[tex]\frac{44}{22}[/tex] = 2

At the end of a party, 3/4 cup of smoked fish dip is left. Jim divides 4/5 of the leftover smoked fish dip equally between 2 friends. How much dip does each friend get?

**Each **friend **gets **3/10 or 0.3 dips if, at the end of a party, 3/4 **cup** of smoked fish dip is **left**.

**Fraction** number consists of two **parts**, one is the **top** of the **fraction** number which is called the **numerator** and the **second **is the bottom of the **fraction** number which is called the **denominator**.

Let each freind get x part.

The 3/4 part dipped:

The value of x can be found as follows:

x = (3/4)(4/5) ÷ 2

x = 3/(5×2)

x = 3/10

x = 0.3

Thus, each friend **gets **3/10 or 0.3 dips if, at the end of a party, 3/4 **cup** of smoked fish dip is **left**.

Does the equation y-250x=500 represent the same relationship between the distance from the start of the trail and the elevation? Explain your reasoning pls

The equation of a line with slope *m* and y-intercept *b* is:

Isolate *y* from the given equation to write it in slope-intercept form:

The given equation corresponds to a line with slope 250 and y-intercept 500.

From the image, we can see that the y-intercept is indeed 500, since it is the value of *y* when *x=0*.

Notice also that for each increase of 1 unit of the variable *x*, the variable *y* increases 250 units. Then, the slope of the graph is 250, the same as the slope of the equation.

We can also check if the equation represents the same line as the graph by evaluating th

10 Caleb divides powers of 10 using exponents . He says that 0.6 divided by increases the value of the 6. Do you agree with Caleb ? 10 ^ 2 Explain your thinking

I **disagree **with Caleb because the **value **decreased after the quotients are carried out

From the question, the statement is given as

*He says that 0.6 divided by 10² increases the value of the 6. *

The **mathematical expression **of the above statement is represented as

0.6 divided by 10²

So, we have

0.6/10²

When the above quotient is evaluated, we have

0.6/10² = 0.006

The above result is **different **from Caleb's reasoning

This is so because 0.6 divided by 10² **decreases **the value of the 0.006, instead of **increasing **the value to 6, as stated by Caleb

XZ¯¯¯¯¯¯¯¯ has a point Y between points X and Z. XY=17, YZ=4x+9, and XZ=11x−9.

Applying the **segment addition postulate**, the value of x = 5.

According to the **segment addition postulate**, if three lines, X, Y, and Z are **collinear points**, that is they lie on a straight line such that Y is between points X and Z, then the sum of the lengths of segments XY and YZ would be equal to the length of segment XZ.

Therefore:

XY + YZ = XZ [**segment addition postulate**]

Given:

XY = 17

YZ = 4x + 9

XZ = 11x − 9.

Substitute

17 + 4x + 9 = 11x - 9

26 + 4x = 11x - 9

26 + 9 = 11x - 4x

**Step-by-step explanation: 7 timestables**

**Answer:**

1/7=4/28=8/56

**Step-by-step explanation:**

From the pattern of the question we can see that the numerator of the second fraction is 4 and the previous fraction's numerator is 1 that means the fraction has been multiplied by 4. Therefore multiplying the numerator and denominator results in the answer 4/28. For the last fraction we can see that the denominator is 56 and is the double of 28 therefore doubling the whole second fraction we get our answer as 8/56. Overall equating all the three fractions we get the same answer 1/7 after minimizing the fraction.

GARDENING Molly's school is planning a school-based community garden with the diagram shownIf the school has 64 yards of fencing for the rectangular garden, use a system of equations and a graphing calculator to find the value of Then find the dimensions of the garden.

The value of x is 5 yards and the** length and width** of the garden is 20 yards and 12 yards respectively.

Given, the school has 64 yards of fencing for the rectangular garden.

we know that, the** perimeter** of the rectangle is the sum of twice the length and twice the width.

length (l) = x²-5

width (w) = 4x-8

therefore, 2(l+w) = 64

⇒ 2(x²-5+4x-8) = 64

⇒ 2(x²+4x-13) = 64

⇒ 2x²+8x-26 = 64

⇒2x²+8x-26-64 = 0

⇒2x²+8x-90 = 0

divide the equation by 2.

⇒ x²+4x-45=0

⇒ x²+9x-5x-45 = 0

⇒ x(x+9) - 5(x+9) = 0

⇒ (x+9) (x-5)

⇒ x = -9 or x = 5

therefore, x cannot be negative,

hence x = 5 yards.

therefore, l = x²-5

l = 5² - 5

l = 25-5

l = 20 yards.

w = 4x-8

w = 4(5) - 8

w = 20-8

w = 12 yards.

Hence we get the value of x as 5 yards and the** dimensions** of the garden as 20 yards by 12 yards,

The Whistling Straits Corporation needs to raise $40 million to finance its expansion intonew markets. The company will sell new shares of equity via a general cash offering toraise the needed funds. If the offer price is $35 per share and the company'sunderwriters charge a 11 percent spread, how many shares need to be sold?

Solution

**Explanation**:

Total Finance Needed = $40,000,000

Offer price per share = $35 per share

Charges of underwriter = 11%

Total Number of shares needed to be sold = ( $40,000,000 / $35 ) x 111%

Total Number of shares needed to be sold = 1,142,857 x 111%

Total Number of shares needed to be sold = 1,267,571 shares

The Whistling Straits Corporation needs **1,267,571** shares to raise $40 million
