Mathematics
1 answer:
Alekssandra [29.7K]3 years ago
5 0

Answer:

Finding x FIRST:

2x-9 = x+5

1x-9 = 5

1x = 14

x = 14

Perimeter = Add all sides

Perimeter of KLM = 15+(2x-9)+8

                             = 15+(2(14)-9)+8

                             = 15+(28-9)+8

                             = 15+19+8

                             = 42 units

Karen gave an equal amount of m and m's to herself and four friends. Each person receives m and m's equivalent to the largest on
Mariana [72]

Answer:

Karen had 45 m and m's candy.

Step-by-step explanation:

Let the number of m and m's candy be 'x'.

Now given:

Karen gave an equal amount of m and m's to herself and four friends.

So we can say that;

Number of people m and m's candy distributed equally = 5

Also Given:

Each person receives m and m's equivalent to the largest one digit number.

Now we know that;

Largest one digit number is 9.

So we can say that;

Each person receives m and m's = 9

We need to find number of m and m's Karen have.

Solution:

So we can say that;

Total number of m and m's Karen have is equal to Number of people m and m's candy distributed equally multiplied by number of m and m's can each person receives.

framing in equation form we get;

Total number of m and m's Karen had = 9\times5 = 45

Hence Karen had 45 m and m's candy.

In the picture below, ABCD is a rectangle. If the area of triangle ABE is 40, what is the area of the triangle?
MariettaO [177]

Area of the rectangle: 112

Step-by-step explanation:

Picture is missing: find it in attachment.

The area of a triangle is given by

A=\frac{1}{2}bh

where

b is the length of the base

h is the height

For triangle ABE, we know that

A = 40 (area)

h = 8 (height)

So we can find the length of the base AE:

AE=b=\frac{2A}{h}=\frac{2(40)}{8}=10

Now we observe that the base of the rectangle, AD, is the sum of AE and DE, therefore:

AD=AE+DE=10+4=14

We also know the height of the rectangle AB is 8, and that the area of a rectangle is

A=bh

where b is the base and h the height. Therefore, the area of this rectangle is

A=bh=(AD)(AB)=(14)(8)=112

Ivanna will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $40 and costs an a
natka813 [3]
First, let's make these two into equations.
The first plan has an initial fee of $40 and costs an additional $0.16 per mile driven.
Our equation would then be
C = 40 + 0.16m
where C is the total cost, and m is the number of miles driven.
The second plan has an initial fee of $51 and costs an additional $0.11 per mile driven.
So, the equation is
C = 51 + 0.11m
where C is the total cost, and m is the number of miles driven.
Now, your question seems to be asking for one mileage for both, equalling one cost. I would go through all the steps I've taken to try and find this for you, but it would probably take hours to type out and read. In short, I'm not entirely sure that an answer like that is possible in this situation, simply because of the large difference in the initial fee of the two plans, along with the sparse common multiples between the two mileage costs.

Write the radical in simplest radical form<br><br><br><br> √5/8
tiny-mole [99]

Answer:

\dfrac{\sqrt{10}}{4}

Step-by-step explanation:

\sqrt{\dfrac{5}{8}} =

= \dfrac{\sqrt{5}}{\sqrt{8}}

= \dfrac{\sqrt{5}}{\sqrt{4 \times 2}}

= \dfrac{\sqrt{5}}{2 \sqrt{2}}

= \dfrac{\sqrt{5}\sqrt{2}}{2 \sqrt{2}\sqrt{2}}

= \dfrac{\sqrt{10}}{2 \times 2}

= \dfrac{\sqrt{10}}{4}
