This is not an equation because it lacks an equal sign....so the only thing we can do here is combine like terms.
4 - 2x - 12 - 2x + 1 =
-4x - 7
Answer:
-8
Step-by-step explanation:
-72 / 9 = -8
Answer:
42%
Step-by-step explanation:
To find the percent of decrease first find the difference between 32.25 and 18.70.
32.25 - 18.70 = 13.55
Now divide this number by the original number, in this case 32.25, and then multiply the answer you get by 100.
13.55 / 32.25 = 0.42
Multiply this number by 100 to get the percentage.
0.42 * 100 = 42
Using the statement and the condition in letter a. The expressions that could represent are:
3j + 5p = 7.60
j + 2p = 2.90
From the equation, we will now equate each other to have the value of j and p, so j = -2p + 2.90:
3(-2p + 2.90) + 5p = 7.60
-6p + 8.70 + 5p = 7.60
-p = -1.10
p= 1.10
j = -2(1.10) +2.90
j = -2.20 + 2.90
j = 0.70
