Four times the lesser of two consecutive even integers is 12 less than twice the greater number. Find the integers.
pashok25 [27]
Oh, this one lol. ok
you gotta read it like its a book.
4 x s(i picked that variable) which is 4s together

4s+12 (if they said'12 less than' then the 12 gotta be adding.)
then u have to divide it so its going to look like this:

4s+12= blah blah blah
'twice the greater number' means you gotta do this: 2(s+2)

so the problem is this: 4s+12=2(s+2)

now you solved it and the answer will beeeeee s=-4

In order to get an A in science, Jack must get at least a 92% on his next test. If test has 30 questions,what is the minimum num
Neko [114]
Jack must score 28 problems correct. To get a 92% he must answer 92% of the 30 questions right. which means 0.92*30=27.6, but it is not possible to score 0.6 of a problem right so you would round to 28, which guarantees Jack scores a 92 because if we round down, Jack would score less than a 92

A bookstore manager marks down the price of older hardcover books, which originally sell for b dollars, by 52%.
mafiozo [28]

Complete question :

A bookstore manager marks down the price of older hardcover books, which originally sell for b dollars, by 52%.

a. Write the markdown as a decimal. b. Write an expression for the sale price of the hardcover book.

Answer:

0.52 ; 0.52b

Step-by-step explanation:

The markdown percentage = 52%

Expresaing markdown as a decimal :

52% = 52 / 100 = 0.52

Expression for the sale price of hardcover book:

Original price = b

Price was marked down by 0.52

Hence, sales price becomes ;

Original price * markdown

b * 0.52

0.52b

Write a minor function for the line with the slope of -5 that passes through points (7,3)
Ilia_Sergeevich [38]

The equation of the line is 5x+y-38=0

Step-by-step explanation:

The slope is m=-5

Also, the line passes through the points (7,3)

To find a line with slope m=-5 that passes through the points (7,3), let us use the equation of a line with slope that passes through the point is given by (y-y_{1} )=m(x-x_{1} ) where m is the slope and (x_{1} ,y_{1} ) are the points (7,3).

Thus, substituting the values in the equation of a line, we get,

(y-3)=-5(x-7)

Multiplying the term (x-7) by -5, we get,

y-3=-5 x+35

Adding both sides by 5x,

5x+y-3=35

Subtracting 35 from both sides of the equation,

5x+y-38=0

Thus, the equation of the line is 5x+y-38=0
