Set up a ratio:

12/5x-2 = 16/6x

Cross multiply:

12(6x) = 16(5x-2)

Use distributive property:

72x = 80x - 32

Subtract 80x from both sides:

-8x = - 32

Divide both sides by -8:

X = 4

X+x-z; use x=3 & z=4​
nadezda [96]

Answer:

2

Step-by-step explanation:

Order of operations is not as applicable in this situation because we're just dealing with addition and subtraction.  This is a simple case of plugging in values for the given expression.

x = 3

z = 4

So it becomes...

3 + 3 - 4

6 - 4

2

So with the given expression of x + x - z and the given values of x = 3 and z = 4, the expression should sum to: 2

A professor grades students on four tests, a term paper, and a final examination. Each test counts as 15% of the course grade. T
alina1380 [7]

Answer:

The Alans's average for the course is 84.5

Step-by-step explanation:

We are given

There are 4 tests, A Term paper and a Final examination.

Score = 92, 78, 82, 90.

Term paper score = 80

Final examination score = 86

Weighted mean = ∑ w.f/∑w

     also the sum of all the weights is 100% = 1

weighted mean = 15%*92 + 15%*78+15%*82+15%*90+20%*80+20%*86/1

                         = 51.3 + 33.2

                         =  84.5

Therefore the Alans's average for the course is 84.5

Someone please help me to find the answer to this geography problem please explain
Kisachek [45]
First, we must know what the two variables in the equation y=mx+b really means.

The M represents slope while the B represents the Y-intercept.

With that out of the way, take a look at your top equation, y = 3/2x + ?. If you noticed the question mark is in the spot of the B (Y-intercept), we can simply find this by finding where on the graph does the line intercept the Y-axis.

Triangle B shows the Y-intercept to be -7, this means that the hypotenuse intercepts the Y-axis at (0 , -7).

If we were to find the (what I like to call) the interception point of triangle A's hypotenuse and the Y-axis, we find our missing variable.

Just looking at the graph, we can count and visually determine that the Y-intercept of the hypotenuse is (0 , 1).

Therefore, we can say: The equation of A's hypotenuse is:
y = 3/2x + 1

Hope I could help you out!
