Andrew has a different cookie recipe that makes 28 cookies. He plans to have 21 guests at the party and wants each guest to have
joja [24]

Answer: Since each recipe makes 28 cookies, tripling the recipe would give him 28(3) = 84 cookies.

Step-by-step explanation: <em>Since each recipe makes 28 cookies, tripling the recipe would give him 28(3) = 84 cookies. </em>

<em> </em>

<em>Then divide the total number of cookies by the number of guests:  84  21  = 4. Each person would get 4 cookies.</em>

<em> </em>

<em>This process can be modeled by the expressions 28(3) ÷ 21 and  </em>

<em>28(3) </em>

<em>21 </em>

<em>. This is because the fraction bar represents division.</em>

Answer: X=-7/2

               y=-11

Step-by-step explanation:

4x+3=2x-4

4x-2x=-4-3

2x=-7

x=-7/2

y=-7/2*2-4

AM is a median in △ABC (M∈ BC ). A line drawn through point M intersects AB at its midpoint P. Find areas of △APC and △PMC, if A
Snowcat [4.5K]

Answer:

The area of APC is 70m². The area of triangle PMC is 35m².

Step-by-step explanation:

Let the area of triangle ABC be x.

It is given that AM is median, it means AM divides the area of triangle in two equal parts.

\text{Area of }\triangle ACM=\text{Area of }\triangle ABM=\frac{x}{2}    .....(1)

The point P is the midpoint of AB, therefore the area of APC and BPC are equal.

\text{Area of }\triangle APC=\text{Area of }\triangle BPC=\frac{x}{2}          ......(2)

The point P is midpoint of AB therefore the line PM divide the area of triangle ABM in two equal parts. The area of triangle APM and BPM are equal.

\text{Area of }\triangle APM=\text{Area of }\triangle BPM=\frac{x}{4}        .....(3)

The area of triangle APM is 35m².

\text{Area of }\triangle APM=\frac{x}{4}

35=\frac{x}{4}

x=140

Therefore the area of triangle ABC is 140m².

Using equation (2).

\text{Area of }\triangle APC=\frac{x}{2}

\text{Area of }\triangle APC=\frac{140}{2}

\text{Area of }\triangle APC=70

Therefore the area of triangle APC is 70m².

Using equation (3), we can say that the area of triangle BPM is 35m² and by using equation (2), we can say that the area of triangle BPC is 70m².

\triangle BPC=\triangle BPM+\triangle PMC

70=35+\triangle PMC

35=\triangle PMC

Therefore the area of triangle PMC is 35m².
