First of all, expand the left hand side:

$4x+4 - 7 < 3x + 5$

Sum like terms:

$4x -3 < 3x + 5$

Add 3 to both sides:

$4x < 3x + 8$

Subtract 3x from both sides:

$x < 8$

So this is the solution. Every number smaller than 8 (excluded) is part of the solution of this inequality.

Lesechka [4]

22.7%

Given that last year stock for company A was $7200
The stock for company B last year was worth $3510
Stock in company A decreased by 24%
This means the new value of stock for company A became;
(100-24)/100 *$7200
76/100*$7200
0.76*7200 =$5472
Stock in company B decreased by 20%
This means the new value of stock for company B became;
(100-20)/100 *$3510
80/100*$3510
0.8*$3510
$2808
Original investors stock value was = $7200+$3510 =$10710
New investors stock value is = $5472+$2808=$8280
Decrease in value of stock = $10710-$8280 =$2430
percentage decrease in stock value = decrease in stock/original value of stock *100%
=2430/10710 *100 =22.689
=22.7%

Measurement is ___________ when it yields the same values across repeated measurement of the same event.

Romashka [77]

<span>The answer is reliable. A measure is assumed to have a high reliability if it yields parallel results under steady conditions. It is the characteristic of a set of test scores that relates to the quantity of accidental or random error from the measurement procedure that might be rooted in the scores. Marks that are highly reliable are precise, reproducible, and constant from one testing time to another. To be exact, if the testing method were to be repeated with a different group of test takers, fundamentally the same results would be gotten. </span>
