Answers

Answer:

40 units

Step-by-step explanation:

3+10+3+4+6+(unknown side: 10+4=14) = 40 units

Answer:

The perimeter would be 38 units.

Explanation:

Add up all sides. 3+10+3+4+6= 24 now we solve for x which is the unmarked side. You would add both of the top lines to find your answer. 10+4= 14. Now add up both totals, 24+14= 38 units as your final answer.

Rule-3 angles of a triangle =180 degrees . One angle is a right angle which is 90 degrees so the remaining 2 must equal 90 so the equation is so 90=(15x)+(8x-2) and now we just have to solve what is the value of x.
First we move -2 to the other side of the equation as +2 so we get 92=15x+8x next we put the 15x and 8x together and get 23 so 92=23 times x. So we divide 92 by 23 and the value of x is 4

Answer:

Step-by-step explanation:

To compare 3/8 with the answer choices, you need to make sure they have a common denominator. You can achieve this by multiplying each answer choice with 4/4 to get a common denominator of 8. Now, your answer choices are: 0, 4/8, 8/8, and 12/8. From these, 4/8 is the closest to 3/8, which means that rounding 3/8 to the nearest half will get you 4/8, which is equal to 1/2. Thus, your answer is 1/2.

Solve for x: 14x = 196.
(Only the number)

Answers

Answer:

14

Step-by-step explanation:

Answer:

the answer is X = 14

Step-by-step explanation:

So you need to single out the X

You do this by doing the opposite of X,

right now X is being multiplied by 14

The opposite of Multiplaction is division

That means you divide X by 14

But dont forget, what you do one side you do to the other.

This means you also Divide 196 by 14

196 ÷ 14 = 14

meaning X = 14

Find the equation of the linear function represented by the table below in
slope-intercept form.
V
5
-10
8

Answers

A linear function in slope intercept form is

y = mx + c

To find the equation, you need m and c. This can be found by substituting the points you have.

For example, 5 = -1(m) + c and -7 = 2(m) + c

From here, do simultaneous equations

c = m + 5

-7 = 2(m) + m + 5

3m = -7 -5

m = -4

c = m + 5

c = 1

Rewrite the equation: (This is your answer)

y = -4x + 1

Baldwin made a scale drawing of the town library. He used the scale 1 centimeter : 9 meters. The parking lot is 9 centimeters in the drawing. How long is the actual parking lot?

Answers

Answer:

81m

Step-by-step explanation:

1/9 = 9/x

x = 81

81 meters
Because the ratio is 1:9 if you wanna change the centimeters you have to do it on both sides
So what times 1 equals 9? 9
So multiply the meters by 9.
