Answer:
-5 and 17
Step-by-step explanation:
The sum of two numbers (let's just say number a and number b) is 12.
a + b = 12
The difference between the same two numbers (still a and b) is 22.
b - a = 22
(Move variable a to the right side to get the following.)
b = 22 + a
(This way, we can substitute b = 22 + a into the first equation, a + b = 12, and solve.)
a + (22 + a) = 12
a + a + 22 = 12
2a = -10
a = -5
a + b = 12
-5 + b = 12
b = 17
Ok so for number 2. There are 101,934 people living in the city and there are 29,382 people in the suburbs. They want the total amount of people living in the whole city. The problem would be 101,934+29,382= and it would equal B. <span>131316. I hope that this helped you.</span><span />
(3x + 4)2 = 14
(3x + 4)2 means that 2 will multiply both 3x and 4
2 * 3x = 6x 2 * 4 = 8
6x + 8 = 14
Move +8 to the other side of the equation
6x = 14 - 8 Note : Moving +8 to the other side will change the sign in front of it, that is from + to -
6x = 14 - 8
6x = 6
Divide both sides by 6 because of the 6 beside the x : 6x
6x/6 = 6/6
x = 1
Answer:
5 cups contain <u>7one-half pounds</u> of candy.
Step-by-step explanation:
Given:
Peter filled 5 cups each with 1one-half pounds of candy.
Now, to find the total candy 5 cups contain altogether.
1 cup of candy contain = 
So, to get candy 5 cup contain we multiply 5 by .
Therefore, 5 cups contain 7one-half pounds of candy.
$7.20 $28.8 $18.8 $225.6 $225.6
4 $10 12 .25 $56.4
X___ -_____ X____ X_____ +_____
$28.8 $18.8 225.6 $56.4 $282
You multiply $7.20 by the 4 hours she's working and you'll get $28.80. Then you would subtract the $10 from your answer and get $18.80. Then you'd multiply $18.80 by 12 for the mouths she's working and get $225.60. Next you multiply $225.60 by .25 from the grandparents and get $56.40. Finally you add $225.60 to $56.40 and get $282 in her savings account.
