Answer:of not

Step-by-step explanation: ops

The measures of the angles are

1. Angle TLN, MZQ and NLM

The angles TLN and NLM are supplementary angles

So, we have

TLN + NLM = 180

This gives

3x - 18 + y = 180

Also, we have

TLN + MZQ = 180

So, we have

3x - 18 + 5x + 14 = 180

Evaluate the like terms

8x -4 = 180

This gives

8x = 184

Divide

x = 23

Substitute x = 23 in 3x - 18 + y = 180

3 x 23 - 18 + y = 180

Evaluate

51 + y = 180

So, we have

y = 129

The above computations imply that:

TLN = 3 x 23- 18 = 51

NLM = y = 129

MZQ = 5 x 23 + 14 = 129

2. Angle JZQ and TLN

The above means that

JZQ = TLN

So, we have

9x + 9 = 8x + 19

Evaluate

x = 10

So, we have

JZQ = TLN = 9 * 10 + 9

JZQ = TLN = 99

3. Angle ZMR, LMO and LMR

The angles ZMR and LMO are congruent angles

So, we have

ZMR = LMO

This gives

x + 14 = 2x - 6

Evaluate

x = 20

Also, we have

LMR + LMO = 180

So, we have

y + 2x - 6 = 180

y + 2 x 10 - 6 = 180

y + 14 = 180

So, we have

y = 166

The above computations imply that:

LMO= ZMR = 20 + 14 = 34

LMR = y = 166

The simple interest that Su Young paid for borrowing $2,900 for 15 months at 5.5% per year is $199.375.

Simple interest is interest that is not compounded.

Compounding involves adding earned interests to the principal when computing the next period's interest.

Principal = $2,900

Period = 15 months or 1.25 years

Interest Rate = 5.5%

Simple interest amount = Principal x Period x Rate

= $199.375 ($2,900 x 1.25 x 5.5%)

Thus, based on simple interest, Su Young paid $199.375.

Answer:

$123.20

Step-by-step explanation:

Hey there!

To find the price for 308 bags of chips FOR 308 people, we need to first know what the price for 1 bag is

It says that it is 2 dollars for 5 bags

Now, we need to divide 2 by 5 to see how much money 1 bag is

2/5 is 0.4 and in this case 0.40 since we're dealing with money

Now that we know this, all we need to do is multiply 0.40 by 308 because we are buying for 308 people

0.40 x 308 is 123.2

This means that for 308 people, it would cost $123.20 to supply them all with a bag of chips!

Answer: Change = - 2.8 gallons

Step-by-step explanation:

Let X be the starting amount of paint in the can, in gallons.

"Removes 5/8 gallon" can be written -(5/8)gal

"Adds 3/8 gallon" becomes +(3/8)gal

The result is :  X - (5/8)gal + (3/8)gal = Remaining Paint (gallons)

Consolidating:  Remaining (gallons) = X - (2/8)gal

If we want the overall increase/decrease, subtract the initial volume:

Initial - Remaining = Change in amount of paint in can

Change =  (X-(2/8)gal) - X = - (2/8) gallons

Answer: f(4) = 8,                     f(-5) = -19,                 f(2-x) = -3x+2

Step-by-step explanation:

Let's start by analyzing what we are given:

f(x)=3x-4

In this equation, f is the name of the function.

The number in the parentheses represents x.

The 3x-4 tells us what the equation does. In this instance, we multiply x by 3 and then subtract 4.

Let's start with (a).

f(4)

Since we have established that the number in the parentheses is x, we can plug 4 in for x into the equation f. We must abide by the order of operations. Therefore, we can obtain the following:

f(4) = 3(4) -4

f(4) = 12 -4

f(4) = 8

We can continue this for part (b).

f(-5) = 3(-5) -4

f(-5) = -15-4

f(-5) = -19

Part (c) is slightly different, but applies the same principles we established previously. On this part, we must recall the distributive property. The 3 multiples the 2 and the x. We must also remember to combine like terms.

f(2-x) = 3(2-x) -4

f(2-x) = 6 - 3x -4

f(2-x) = -3x +2
