UW= 2 and UX=y. Write an expression for WX
Eddi Din [679]
Divide each term by U and simplify. X=y/U and W=2/U. Next, solve the equation for y. Simplify the left side then cancel the common factor of U. 1/1*y/1=y

W=2/U. Multiply 1/1*y/1=y/1 so, y/1=y and W=2/U. Next, divide y/y to get 1 now y=y, still W=2/U. Now, move all terms containing y to the left side.  Since, Y contains the variable to solve for, move it to the left side of the equation by subtracting y from both sides. Now, y-y=0 still W=2/U.  Next, subtract y from y to get zero and still W=2/U.  Subtract y from y to get zero or 0=0 and W=2/U is your expression since 0=0.


Next: UW=m and WX=y+14  write expression for UX

First, divide each term by W and simplify. U=m/W, WX=y+14. Next, solve the equation for Y. Move y from the right side of the equation to the left side. Still, U=m/W and y=-14+WX.  We must reorder -14 and WX. U=m/w and y=WX-14.
Replace the variable U with m/W in the expression to (m/W)X. Next, simplify (m/W)X. Now, write X and a fraction with denominator 1. Looks like this
fractions are side by side m/W X/1 . Multiply, m/W and X/1 to get mX/W.
mX/W is your final expression for UW=m and WX=y+14 expression for UX.

A magician has a collection of 52 cards, with 26 red and 26 black cards. Four of these cards are classified as 'special', and tw
Brums [2.3K]

Answer:

option B (28/52)

Step-by-step explanation:

from probability

P(A∪B)=P(A)+P(B)-P(A∩B)

where

P(A∪B) = probability that event A or B happen

P(A∩B) = probability that event A and B happen simultaneously

P(A) =  probability that event A happen

P(B) =  probability that event B happen

the probability that the card is special or red

P( special or red)= P(special) + P(red) - P( special and red)

since

P(special)= 4/52

P(red) = 26/52

P( special and red) = 2/52

therefore

P( special or red)= 4/52 + 26/52 -  2/52 = 28/52

P( special or red)= 28/52

(option B)

What is the product?
Anit [1.1K]

The final answer will be a 3x3 matrix. So you'll have 3 rows and 3 columns.

Along row one, the values are:     10,   15,    20

Along row two, the values are:      45,  -5,   -35

Along row three, the values are:   55,  25,   -15

all of which make up the final answer. Each value in bold is the result of multiplying the outer 5 by each value inside the original matrix given. In a sense, it's like using the distributive property, though we wont be adding any of the values (everything stays separated).

A local playground is rectangular and has an area of 76.5 square meters. One side of the playground is 10 meters long. Maria say
Aleks04 [339]

Answer:

The length of the other side is 7.65m

Step-by-step explanation:

Maria's mistake was that she wanted to move the decimal point 2 places to the left, when she should have moved it 1 place, since that is the number of zeros that the number 10 has.

To find the length of the rectangle, we simply divide the area by the width

a = area = 76.5 m

w = width = 10m

l = length

l = a/w

l = 76.5m² / 10m

l = 7.65m

The length of the other side is 7.65m
