Answer:
-10x² - 7x + 7
Step-by-step explanation:
Subtract:
- -5x² - 8x - 1 - (5x² - x - 8)
- -5x² - 5x² - 8x + x - 1 + 8
- -10x² - 7x + 7
Remember: subtracting a negative number is adding that number

Given 16 Tablespoons ; Convert to "mL" .
Note: "milliliters" can be abbreviated as "mL" .
Note: 15 mL = 1 Tablespoon .
16 Tablespoons * (
) ;
= (16 * 15) mL
= 240 mL .

Step-by-step explanation:
Answer:
Given:
, y =6
To prove: x =7
On substituting the value of y =6 in the equation 7y = 8x -14 to solve for x.
or
42 = 8x -14 ......[1]
Addition Property of equality states that you add the same number to both sides of an equation.
Add 14 to both sides in equation [1];
42+14 =8x -14+14
Simplify:
56 = 8x
or
8x =56 ......[2]
Division Property of equality states that you divide the same number to both sides of an equation.
Divide by 8 to both sides of an equation [2];

Simplify:
x =7 Hence proved!
A two Column proof:
Statement Reason
1. 7y = 8x -14 Given
y= 6
2. 7(6) = 8x -14 Substitution property
3. 42+14 = 8x Addition property of equality
4. 56 =8x Simplify
5. x =7 Division Property of equality
No, 15% of 81 is 12.5 and 81+12.5 is only 93.5 and she needs at least a 95
