7. If A = 2x + 3 and B = x^2 - 5x + 1, what is the value of A-5B?​

if the value of 10x + 3 were 4, then it would follow that x = 0.1 ... 5x = 10. Dividing each side of 5x = 10 by 5 gives x = 2. Finally, substituting. 2 for x ... ues of x, the two sides of the equation are equal, and the value of b can be deter- ... Choice A is incorrect because −1 is the value of x, not the value of 7 + 2x.

Step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
