Answer:

<h2>Average speed is 15km/h</h2>

Step-by-step explanation:

Step one:

given data:

total distance =7.5km

time taken= 30 min= 0.5 hours

we know that the average speed is the average distance divided by time taken

Step two:

mathematically expressed as

speed=distance/time

substituting we have

speed=7.5/0.5

speed=15km/hour

Hence the average speed is 15km/h

Solve equation 1/3(x-10)=-4
Maksim231197 [3]

<em><u>The value of x is -2</u></em>

<em><u>Solution:</u></em>

<em><u>Given equation is:</u></em>

\frac{1}{3}(x-10) = -4

We have to solve the given equation

From given,

\frac{1}{3}(x-10) = -4

Solve so that "x" is in left side of equation and move the remaining terms to other side of equation

x - 10 = -4 \times 3\\\\Simplify\\\\x - 10 = -12\\\\Isolate\ for\ x\\\\x = -12 + 10\\\\x = -2

Thus the value of x is -2

Write the slope-intercept form of the equation of each line given the slope and y-intercept.
Brut [27]

Answer:

y = -1/4x+2

Step-by-step explanation:

The SIF (slope intercept form) is pretty easy once you get it down. the slope is the interger before x, and the y-intercept is b. so, if you input each number into it's spot, it would become y = -1/4x + 2.

Please need help fast thank you. The problem is in the picture.
egoroff_w [7]

Answer:

Angles 2, 3, 6, 7

Step-by-step explanation:

Since supplementary means to add up to 180 degrees, or a straight angle, we just find which angles are connected with a straight line.

These angles would be Angle 2 and Angle 3.

Since we have a whole figure, we also need to find the corresponding angles for Angle 2 and Angle 3. (Corresponding angles are the same degree as the original angle.)

The Corresponding angles to Angle 2 and Angle 3 are Angle 6 and Angle 7 respectively.

Thus, our answer is Angles 2, 3, 6, and 7.
