I need to know what the value is for x

Mathematics

4/6 = x + 3/ 12 - x
4( 12 - x) = 6( x + 3)
48 - 4x = 6x + 18
-4x - 6x = 18 - 48
- 10x = -30
x = 3

Hazel has already written 2 pages, and she expects to write 2 pages for every additional
denpristay [2]

Answer:

50 pages

Step-by-step explanation:

We can set up an equation for this in slope-intercept form.

The slope is 2 due to her expecting to write 2 pages an hour.

The y-intercept is 2 because she has already written 2 pages.

The full equation is y = 2x + 2.

We can plug 24 in for x to get y = 48 + 2, which simplifies to y = 50.

Points P and Q belong to segment AB . If AB = a, AP = 2PQ = 2QB, find the distance: midpoints between AP QB
Digiron [165]

Answer: The distace between midpoints of AP and QB is \frac{a}{8}.

Step-by-step explanation: Points P and Q are between points A and B and the segment AB measures a, then:

AP + PQ + QB = a

According to the question, AP = 2 PQ = 2QB, so:

PQ = \frac{AP}{2}

QB = \frac{AP}{2}

Substituing:

AP + 2*(\frac{AP}{2}) = a

2AP = a

AP = \frac{a}{2}

Since the distance is between midpoints of AP and QB:

2QB = AP

QB = \frac{AP}{2}

QB = \frac{a}{2}*\frac{1}{2}

QB = \frac{a}{4}

MIdpoint is the point that divides the segment in half, so:

<u>Midpoint of AP</u>:

\frac{AP}{2} = \frac{a}{2}*\frac{1}{2}

\frac{AP}{2} = \frac{a}{4}

<u>Midpoint of QB</u>:

\frac{QB}{2} = \frac{a}{4}*\frac{1}{2}

\frac{QB}{2} = \frac{a}{8}

The distance is:

d = \frac{a}{4} - \frac{a}{8}

d = \frac{a}{8}

Pls help me i need to fill in the boxes that dont have anything in them but i aldo need to fill in the one that says "A="​
Temka [501]

Answer:

Area is 20

Perimeter is 24

A= L × W

Step-by-step explanation:

Area is found by multiplying the length by the width, which in this case is 10 × 2 = 20

Perimeter is found by adding all of the sides together, so 2 + 2 + 10 + 10 = 24

A= Legnth × Width or vise versa
