Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
x + 2x + 3x = 180
6x = 180 ( divide both sides by 6 )
x = 30 → A
Answer:
A) 30
Step-by-step explanation:
The sum of all of the angles in a triangle have to equal 180 degrees.
Plug in 30 for x
3(30) = 90
2(30) = 60
(30)= 30
90+60+30= 180
Therefore x=30 degrees

What is the point-slope form of a line that has a slope of 5 and passes through the point (3, –4)?
y – 3 = 5[x – (–4)]
–4 – y1 = 5(3 – x1)
y – (–4) = 3(x – 5)
y – (–4) = 5(x – 3)
Answers
Point slope form is:
y-y1=m(x-x1)
m is your slope. They tell us the slope is 5. They also give you an ordered pair. Substitute this ordered pair into the point slope equation for the x1 and y1 values.
Answer:
The answer is: y - (-4)= 5(x-3)
Point slope form is:
y-y1=m(x-x1)
m is your slope. They tell us the slope is 5. They also give you an ordered pair. Substitute this ordered pair into the point slope equation for the x1 and y1 values.

The credit remaining on a phone card (in dollars) is a liner function of the total calling time made with the card (in minutes) the remaining credit after 30 minutes of calls is $15.20 of the remaining credit after 46 minutes of the call is $12.64 what is the remaining credit after 54 minutes of calls?
Answers
Answer:
$11.36 (11 dollars and 36 cents).
Step-by-step explanation:
This scenario can be written as the linear equation: y = -$0.16x + $20 Where y is the remaining credit, and x is the minutes spend calling.
To find the remaining credit after 54 minutes,
substitute 54 for x and simplify.
So y = -$0.16(54) + $19.60 = -$8.64 + $20.00 =
$20.00 - $8.64 = $11.36.

If you want to solve this problem from scratch, first find the constant rate of money by subtracting 30 minutes (time) over $15.20(total) by 46 minutes over $12.64(total).
Just subtract across, and simplify to get the rate, and then apply that rate between the missing total of 54 minutes and the total of $12.64 dollars for 46 minutes. This is because rate = change quantity/change in time. If that rate is constant as it is in this relationship where the quantity is the amount of anything that is dependent on something, in this case it's money.
So subtract (find the difference) to find the pattern of change between these values in respect to time.
15.20/ 30 - 12.64 / 46 = 2.56 / -16 = 1.28 / -8 = 0.64 / -4 = 0.32 / -2 = 0.16 / -1 = -0.16 [This is the rate decrease in money every minute of a call being made or decrease in remaining credit every minute ].
Now since we know the rate, we can solve the missing factor of the problem by multiplying the rate by the change in time to get the change in quantity.
So : 54 - 46 = 8. 8 × 0.16 = 1.28 [This is the change in quantity from 46 to 54 minutes of calling ].
Therefore, $12.64 [remaining credit from 46 minutes ] - $1.28 [the change of credit from 46 minutes to 54] = $11.36 [remaining credit from 54 minutes].
Also in general, Rate = dependent variable / independent variable.

– 6x + 11 = – 7 step by step
Answers
First let's add 6x to both sides. We do this because the 6x is negative and by adding 6x to both sides, we are isolating the 11 and we are also making the 6x positive, which makes things easier later.
-6x + 11 = -7
+6x +6x
11 = -7 + 6x
Now let's flip the equation to make it easier to read:
-7 + 6x = 11
And let's add 7 to both sides as we need to isolate the 6x. We are adding 7 because the 7 is negative.
6x = 18
And finally to get the value of x we divide both sides by 6:
x = 3

Janice wants to invest $1,000. Texas Loan & Credit will offer Janice an annual simple interest rate of 6% that is paid upon withdrawal. Pecan & Cedar Savings Bank will offer Janice an interest rate of 3% that is compounded annually. Which Bank will yield better interest earnings after investing $1,000 for 2 years?
Answers
Answer:
Texas Loan & Credit will yield better interest earnings after Janice invested $1,000 for 2 years.
The interest earnings will be $120 as against Pecan & Cedar's $60.90.
Explanation:
Texas Loan & Credit:
Simple interest rate = 6%
Janice's Investment = $1,000
Interest earnings = $120 ($1,000 * 6% * 2)
Pecan & Cedar Savings Bank:
Compound interest rate = 3%
Janice's investment = $1,000
Interest earnings = $60.90 ($1,000 * 3%) + ($1,030 * 3%)
In the second year, the interest earnings of $30 are added to the principal to get a new compounded principal of $1,030 on which 3% is also applied.

Answer:
x = [tex]\sqrt{21}[/tex]
Step-by-step explanation:
AC² = AB² + BC²
BC² = 3² + x² = 9 + x²
AB² = 7² + x² = 49 + x²
But AC² = (7 + 3)² = 100
∴ 100 = 49 + x² + 9 + x²
2x² + 58 = 100
x² = 50 - 29 = 21
x = [tex]\sqrt{21}[/tex]
