Rewrite to remove fractions
The denominators in the above expression are 4 and 6.
So, first we take the LCM of 4 and 6
[tex]LCM = 12[/tex]
Next, multiply both sides of the equation by this LCM (12)
[tex]12 ( \frac{3}{4}x - 5) = \frac{5}{6} * 12[/tex]
[tex]12 * \frac{3}{4}x - 12 *5 = \frac{5}{6} * 12[/tex]
[tex]3 * 3x- 60=5 * 2[/tex]
[tex]9x- 60=10[/tex]

Find the length of each missing side and each missing angle in the equilateral triangles below
Answer:
z=4.2ft
x=60 º
y=60 º
Step-by-step explanation:
Because the triangle is equilateral, all sides are the same, so z=4.2
Also because it is equilateral, all angles of the triangle equal 60 º.
Answer:
4.2ft
Step-by-step explanation:
This is an equilateral triangle so all sides and angles will be the same
A square has a side length of 2.3cm if the square is dilated by a scale factor of 3 what is the length of the new side
Answer:
[tex]New\ Side = 6.9cm[/tex]
Step-by-step explanation:
Given
[tex]Length = 2.3cm[/tex]
[tex]Scale\ Factor = 3[/tex]
Required
Determine the length of the new side
This is calculated as follows:
[tex]New\ Side = Length * Scale\ Factor[/tex]
Substitute values for Length and Scale Factor
[tex]New\ Side = 2.3cm * 3[/tex]
[tex]New\ Side = 6.9cm[/tex]
Hence, the length of the new side is 6.9cm
You deposit $500 in an account that earns simple interest. The difference between the total interest earned after 3 years and the total interest earned after 1 year is $30. What is the annual interest rate? please show formula as well
Answer:
[tex]3\%[/tex] p.a.
Step-by-step explanation:
The formula for simple interest is [tex]I=PRT[/tex] ([tex]I =[/tex] interest, [tex]P =[/tex] principal, [tex]R =[/tex] rate)
First, let's express the interest earned in one and three years:
[tex]I_{1} = PRT_{1}[/tex] (finding the interest earnt in one year)
[tex]I_{1} = \$ 500\times R \times 1[/tex]
[tex]=\$ 500R[/tex]
[tex]I_{2} = PRT_{2}[/tex] (finding the interest earnt in three years)
[tex]I_2 = \$ 500 \times R \times 3[/tex]
[tex]=\$ 1500R[/tex]
From the information "The difference between the total interest earned after 3 years and the total interest earned after 1 year is $30", we can write:
[tex]I_{2}-I_{1} = \$ 30[/tex]
[tex]\$ 1500R - \$500 R = \$ 30[/tex]
[tex]\$ 1000R = \$ 30[/tex]
[tex]R = 0.03[/tex]
[tex]=3\%[/tex] p.a.
∴ The annual interest rate is [tex]3\%[/tex]
Hope this helps :)
The annual interest rate if You deposit $500 in an account that earns simple interest. The difference between the total interest earned after 3 years and the total interest earned after 1 year is $30 is 3%.
What is interest?When the loan is given to you, then some amount is charged to you for the principal amount and that is called interest.
Given:
The principal amount, P = $500,
Time, t = 1 year and T = 3 year,
Calculate the interest by the formula given below,
[tex]SI = P\times R\times T / 100[/tex]
Here, SI is the simple interest.
So for 1 year time,
Substitute the values,
SI = 500 × R × 1 / 100
SI = 5R
Now for 3 year
SI = 15R
But 15R - 5R = 30 (Given in question)
R = 3%
Therefore, the annual interest rate if You deposit $500 in an account that earns simple interest. The difference between the total interest earned after 3 years and the total interest earned after 1 year is $30 is 3%.

Answer:

-6
Step-by-step explanation:
x=-6
Final Answer: [tex]x = -6[/tex]
Steps/Reasons/Explanation:
Question: What is [tex]\frac{1}{3} (x + 15) = 3[/tex]?
Step 1: Simplify [tex]\frac{1}{3}(x + 15)[/tex] to [tex]\frac{x+15}{3}[/tex].
[tex]\frac{x + 15}{3} = 3[/tex]
Step 2: Multiply both sides by [tex]3[/tex].
[tex]x + 15 = 3[/tex] × [tex]3[/tex]
Step 3: Simplify [tex]3[/tex] × [tex]3[/tex] to [tex]9[/tex].
[tex]x + 15 = 9[/tex]
Step 4: Subtract [tex]15[/tex] from both sides.
[tex]x = 9 - 15[/tex]
Step 5: Simplify [tex]9 - 15[/tex] to [tex]-6[/tex].
[tex]x = -6[/tex]

6. What's the Error? Abram said the table at the right
does not show a function. Explain the error.
Penelope leaves her house. For eight minutes, she drives to the store at a rate of one block per minute. Then, she stops for five minutes to shop in the store. Finally, she drives back to her house at a rate of four blocks every three minutes. Write the equation to model Penelope's trip to the store.
Answer:
T = 8 + 5 + 6
Step-by-step explanation:
Since it took Penelope 8 minutes to drive to the store at a rate of 1 block per minute then that means the store was 8 blocks away. That being the case if she drives back home from the store at 4 blocks every 3 minutes that would mean that she took 6 minutes (4+4 = 8) to get back home. Using this data we can create the following equation model to calculate the total time of the trip.
T = 8 + 5 + 6
