Answer:
The only complete ordered pair in the given table is:
5 months → $60 saved
Therefore, to determine the <u>relationship between the variables</u>, divide the amount saved by the number of months:
So we can assume that <u>$12 is saved each month</u>.
To complete the table:
- <em>Multiply</em> the given number of months by $12 to determine the <u>amount saved</u>.
- <em>Divide</em> the given amount saved by $12 to determine the <u>number of months</u>.
⇒ 3 × $12 = $36
⇒ $72 ÷ $12 = 6
⇒ 10 × $12 = $120
Completed table:
X-7 is the answer because youre taking seven from a variable
Answer:
part A= x=1
part B= -13=-11 and -7=-7 and -2=-2
Step-by-step explanation:
part A
5+x-12=x-7
-7+x=x-7
x=1
part B
5+(-4)-12=-4-7
-1-12=-4-7
-13=-4-7
-13=-11
5+x-12=x-7
5+(-12)=-7
-7=-7
5+x-12=x-7
5+5-12=5-7
10-12=-2
-2=-2
Answer:
Step-by-step explanation:
A) Use the distributive property to eliminate parentheses. Then combine like terms. (The only "like terms" are the constants.)
... = 12 +3·2y +3·(-3) . . . use the distributive property to multiply each term in parentheses by the factor 3 outside those parentheses
... = 12 +6y -9 . . . . . . . . simplify
... = 6y + (12 -9) . . . . . . group like terms together
... = 6y + 3 . . . . . . . . . . simplify
___
B) Look for factors of each term that are also found in the other term.
... 18b has factors 3×6×b
... 12 has factors 2×6
The only common factor is 6, so we factor that out using the distributive property.
... 18b -12 = 6(3b -2)

<em>Comment on factoring</em>
For factoring problems, it helps immensely if you know your times tables and some of the rules for divisibility. (Even numbers are divisible by 2, numbers ending in 0 or 5 are divisible by 5, numbers whose sum of digits is divisible by 3 are divisible by 3, for example.)
3 of my friends and I were eating chips. We each ate 2/3s of a bag. In total, how much chips did we eat?
