The formula for the area of a triangle is a = zon, where b is the length of the base and h is the height.
Find the height of a triangle that has an area of 30 square units and a base measuring 12 units.

Answer:

10 3/4

Step-by-step explanation:

\(x + \frac{7}{4} = - \frac{5}{2} \times - \frac{5}{1} \\ x = \frac{25}{2} - \frac{7}{4} \\ x = \frac{43}{4} \\ x = 10 + \frac{3}{4} \)

Answer:

X = 1

Step-by-step explanation:

Since the angles are alternate exterior angles, they're equal to each other. This means that you can set 54 - 8x and 48 - 2x equal to each other. After you add 2x to both sides, then subtract 48 from both sides, and divide by 6 to get x by itself, you get x = 1 as a result. :)

Answer:

C. -6.1, -6 4/9, 6.3..., 630%

Step-by-step explanation:

-6.1 in mixed number form is -6 1/10, making it greater than -6 4/9. This is because, if the numbers were positive, -6 4/9 would be greater than -6.1, but since the numbers are negative, it's opposite.

Therefore, the answer is:

C. -6.1, -6 4/9, 6.3..., 630%

Answer:

C = 15m

Step-by-step explanation:

Since the almonds are $15 per kg, the cost can be represented by 15m, where m is the number of kg.

To create the equation, set this equal to C, the cost in dollars:

C = 15m

So, the equation is C = 15m

Here is an equation to represent the relationship between the cost, C, in dollars, and the mass, m, in kg of almonds sold at a rate of $15 per kg at a local store: C = 15m

The mass of the almonds closely relates to how much they cost. This implies that the price of almonds will rise along with the mass of the nuts. Since the proportionality constant is $15, the price will be $15 for every kilogram of almonds.

Let's use an illustration to try to comprehend this. A 2 kg purchase of almonds will cost $30. Since 2 x 15 = 30, this is the case.

Answer:

1/3(x-7)

Step-by-step explanation:

If you divide both the x value (1/3) and the constant value (7/3) by 1/3, you will get 1/3(x-7).

(Please let me know if this is right.)

This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:

x^2-2y=3 - (x-2y=3) => x^2-x=0

Then we can factor the resulting equation and find the values of x:

x^2-x=0 => x(x-1)=0 => x=0 or x=1

Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:

x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1

Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:

x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1

Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Answer:

number 59

Step-by-step explanation:

Answer:

To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:

Step 1: Distribute the negative sign on the left side of the equation:

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

=> -x - 3 = 2(x - 3) (using the distributive property)

Step 2: Expand the right side of the equation:

-x - 3 = 2x - 6

Step 3: Add x to both sides of the equation to isolate the x term on one side:

-x + x - 3 = 2x + x - 6

=> -3 = 3x - 6

Step 4: Add 6 to both sides of the equation:

-3 + 6 = 3x - 6 + 6

=> 3 = 3x

Step 5: Divide both sides of the equation by 3 to solve for x:

3/3 = 3x/3

=> 1 = x

So, the correct value of x that makes the equation true is B. 1.

PLEASE MARK BRAILYISTT :D

Answer:

B, one

Step-by-step explanation:

In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.

Answer: The correct amount Vince will pay back altogether is $927 and this can be determined by using the simple interest formula.

Step-by-step explanation:

Given :

Vince borrows $900 to buy a couch.

He will pay off the loan by paying 1.5% simple interest for 2 years.

Vince incorrectly calculates the amount he will pay back using the expression below. 900 + 900(1.015  2).

The following steps can be in order to determine the correct amount Vince will pay back altogether:

Step 1 - The formula of simple interest can be used in order to determine the correct amount Vince will pay back altogether.

Step 2 - The formula of simple interest is given below:

where A is the final amount, P is the principal amount, R is the interest rate, and T is the time.

Step 3 - Substitute the values of the known terms in the above expression.

A = 900(1 + 1.015  2)

Step 4 - Simplify the above expression.

A = $927

Median definition: the value in the middle of a data set, meaning that 50% of data points have a value smaller or equal to the median and 50% of data points have a value higher or equal to the median.

If the number of values is even, you'll have to find the number between the middle values. If it's odd, you find the number in the middle

There's 11 values which is an odd number. 21 is in the middle, making it the median.
