Answer:

<h3>Each of the given pairs is not a solution to the given equation.</h3>

Step-by-step explanation:

Put the x and y values in the equation 4y = -7x + 5 and check the equality of the left and right side of the equation.

A. x = -5 and y = 0

L = 4(0) = 0

R = -7(-5) + 5 = 35 + 5 = 40

L ≠ R

B. x = -3 and y = 4

L = 4(4) = 16

R = -7(-3) + 5 = 21 + 5 = 26

L ≠ R

C. x = 1 and y = 3

L = 4(3) = 12

R = -7(1) + 5 = -7 + 5 = -2

L ≠ R

D. x = 2 and y = -2

L = 4(-2) = -8

R = -7(2) + 5 = -14 + 5 = -9

42 in a 4x to 3x ratio

4x + 3x = 42
7x = 42
x = 6

43 can be put in a 4(6) to 3(6) ratio

which is a 24 to 18 ratio, also written as 24:18

An electronics retailer receives a shipment of 6,000CDs to distribute to its stores. A quality control manager inspects a random

Alex17521 [72]

Answer: 300

Step-by-step explanation:

Given , An electronics retailer receives a shipment of 6,000CDs to distribute to its stores.

i.e, Total CD's he has now = 6,000

Also, a quality control manager inspects a random sample(S) of 40CD's , the number of defective(D) CD's are 2.

Then , the proportion of defective( D) CD's = $\dfrac{D}{S}=\dfrac{2}{40}=0.05$

Now , the number of CDs in the shipment are likely to be defective = ( Total CD's) x (proportion of defective CD's)

= 6000 x 0.05

=300

Hence, the number of CDs in the shipment are likely to be defective =300

Step-by-step explanation:

sum of three no =94

first no =X

second no x-8

third no =4(x-8)

X+(x-8)+4x-32=94

6x-40=94

6x=94-40

6x=54

X=54/6

X=9
