The difference of the numbers given as -3.3 - (-0.6) is -2.7

<h3>How to subtract the numbers using a number line?</h3>

The difference of the numbers is given as

-3.3 - (-0.6)

Open the brackets, in the above expression

So, we have:

-3.3 - (-0.6) = -3.3 + 0.6

The above expression means that we make a mark on the number line at point 0.6 and then move the points on the number line to the left by 3.3 units.

So, we have the result to be:

-3.3 - (-0.6) = -2.7

This means that the last position on the number line is -2.7

Hence, the value of the difference of the numbers given as -3.3 - (-0.6) is -2.7

JK is similar to PQ
KL is similar to QR

Make a proportion

$\sf{ \frac{JK}{PQ} = \frac{KL}{QR} }$

Plug in the numbers

$\sf{ \frac{36}{6} = \frac{24}{QR} }$

Cross multiply

$\sf{36\times QR= 6 \times 24}$

Solve for QR

$\sf{ QR=4}$

So your final answer is

$\boxed{\bf{4~centimeters}}$

We are interested in the dimensions of a certain rectangle. This rectangle has length 5 units more than the side of this square

kykrilka [37]

Let s be the measure of the measure of the sides of the square such that its area is s². From the conditions above, the length of the rectangle is s + 5 and its width is 0.5s. The area of the rectangle is (s+5)(0.5s)
s² = (s + 5)(0.5s)
The value of s is 5. Thus the dimension of the rectangle in w x h is 2.5 x 10.

Given the equation –2x + 3y = 18, what are the x-intercept and y-intercepts of the graph?

bogdanovich [222]

Y-intercept happens at x=0. Plug that into the equation. you'll get the y-intercept happens at (0,6). Then, to find the x-intercept y=0. Plug that into the equation. You'ff find that the x-intercept happens at (-9,0)

A. incenter

point w is shown in the triangle formed by 3 different lines. these lines are called angle bisectors, and the point at which the angle bisectors meet is called the incenter of a triangle

Lines e and f are parallel. The mAngle9 = 80° and mAngle5 = 55°. Parallel lines e and f are cut by transversal c and d. All angl

brilliants [131]

Answer:

$(A)m\angle 2=125^\circ\\(C)m\angle 8=55^\circ\\(E)m\angle 14=100^\circ$

Step-by-step explanation:

The diagram of the problem is drawn and attached.

Given that:

$m\angle 9 =80^\circ\\m\angle 5 =55^\circ$

$m\angle 5+ m\angle 6=180^\circ\\55^\circ+ m\angle 6=180^\circ\\m\angle 6=180^\circ-55^\circ\\m\angle 6=125^\circ\\$Now:\\m\angle 6 = m\angle 2 $(Corresponging angles)\\Therefore m\angle 2=125^\circ\\$

$m\angle 5= m\angle 8=55^\circ $(Vertically Opposite Angles)$

Also

$m\angle 9+ m\angle 10=180^\circ\\80^\circ+ m\angle 10=180^\circ\\m\angle 10=180^\circ-80^\circ\\m\angle 10=100^\circ\\$Now:\\m\angle 10 = m\angle 14 $(Corresponging angles)\\Therefore m\angle 14=100^\circ\\$
