Answer:

twelve decreased by twice a number > 12 - 2x

8 times the sum of number and 4 > 8 (x + 4)

12 - 2x = 8 (x + 4)  then 12 - 2x = 8x + 32 (distributive property)

12 = 10x + 32 (add 2x to both sides)

-20 = 10x (subtract 32 from both sides)

x = -2 (divide both sides by 10)

Let x be the number.
"twelve decreased by twice a number" ---> 12 - 2x
"8 times the sum of number and 4" ---> 8(x + 4)
12 - 2x = 8(x + 4)
12 - 2x = 8x + 32 (distributive property)
12 = 10x + 32 (add 2x to both sides)
-20 = 10x (subtract 32 from both sides)
x = -2 (divide both sides by 10)

2 and 1/4 yard is how many inches
BartSMP [9]
First you need to find out how many inches are in a yard. After that, times that by 2 1/4 or use the improper fraction form 9/4 which I am going to use.

We know there is 36 in = 1yd

36 x 9/4 = 324 / 4
324 / 4 = 81 inches

PLEASE HELP!!!
igomit [66]

Answer:

Step-by-step explanation:

-2(p + 4) = 3 - 3p + 1p.....combine like terms

-2(p + 4) = 3 - 2p...distribute the -2 through the parenthesis

-2p - 8 = 3 - 2p

-2p + 2p = 3 + 8

0 = 11 <==== no solution

if it is a false statement, it has no solutions

if it ends like : 6 = 6 or -2 = -2, then there is infinite solutions

if it ends like : x = 8 or x = -5, then there is 1 solution

PLEASE HELP ASAP! ALGEBRA!<br><br> (0,5), m=1/3 in point slope form
n200080 [17]

Answer:

y - 5 = 1/3(x - 0)

Step-by-step explanation:

the formula for point-slope form is y2 - y1 = m(x2 - x1), where m is the slope, y1 is the y coordinate and x1 is the x coordinate

so just plug in the values into the equation:

y - 5 = 1/3(x - 0)

if you want it in slope-intercept form, the formula is: y = mx+b, where mx is the slope and b is the y intercept. it would look like the following:

y = 1/3x + 5
