Answer:
Step-by-step explanation:
1. 3x2 + 5x - 4 + 6x2 - x + 7
= combining like terms
= 9x2 + 4x + 3
2. 2y2 - 3y + 6 + y2 - 5y - 1 + (-4) + 2y2 - 2y
= 5y2 - 10y + 1
3. 2x2y - 3xy2 + x2y - 4x2y - 2xy2
= - x2y - 5xy2
4. x2 - y2 + 2x2 - 3xy + 4y2 + 3y2 - 5xy - x2
= 2x2 - 8xy + 6y2
If jeanette had $936 in her checking account then the money in her savings account was 1/6 of this which is $156
Thats a total of 936 + 156 = $1092.
After moving the money to savings account the ratio savings : checking in 4:3 so she has 4/7 * 1092 = $624 in savings and 3/7 * 1092 = $468 in checking account.
Answer: 624 dollars in savings and 468 dollars in the checking account
Answer:
90°
Step-by-step explanation:
Since they are vertical angles, they equal eachother
4x+15=5x-5
add the 5 to both sides
4x+19=5x
subtract the 4x from both sides
x=19
Then you have to plug in 19 to find the measure of ZA
4(19)+14
76+14
90
Answer:
<h2><em><u>x = 5</u></em></h2>
Explanation:
11 - x < 7
- 11 minus a number is less than 7
<em>Insert 5 into the equation</em>
11 - 5 < 7
<em>Simplify</em>
6 < 7
<em>Insert 3 into the equation</em>
11 - 3 < 7
<em>Simplify</em>
8 < 7
<h3><u><em>x = 5 is a solution to the equation 11 - x </em></u><u>< 7</u></h3><h3><u /></h3>
