Answer:
13n +9
Step-by-step explanation:
There is nothing to solve. We can simplify the expression by eliminating parentheses and combining like terms.
7n +6(n +4) -15 . . . . . . given
7n +6n +6(4) -15 . . . . use the distributive property
(7 +6)n +(24 -15) . . . .identify and group like terms
13n +9 . . . . . . . . . . combine like terms
<span>A) -x+y=4
B) 6x+y= -8
Multiplying "A" by -1
A) x -y = -4 then adding it to B
B) 6x + y = -8
7x =-12
x = -12/7 = </span><span>-1.7142857143
y = 4 + x = </span><span><span><span>2.2857142857
</span></span></span>Did you make a typo because as you can see, the solution is not one of the 4 choices.
Answer:
<h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>3</u></em><em><u> </u></em><em><u> </u></em><em><u>&</u></em><em><u> </u></em><em><u>y</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>5</u></em></h2>
Step-by-step explanation:
<h3>
<em><u>Given</u></em><em><u>, </u></em></h3>
(x+1, 10) = (4, 2y)
<u>First</u><u> </u><u>x</u><u> </u><u>coordinate</u><u>, </u>
x + 1 = 4
=> x = 4 - 1
=> <em>x = 3 (Ans) (i)</em>
<u>Second</u><u> </u><u>y</u><u> </u><u>coordinate</u><u>, </u>
10 = 2y

=> <em>y</em><em> </em><em>=</em><em> </em><em>5</em><em> </em><em>(</em><em>Ans</em><em>)</em><em> </em><em>(</em><em>ii</em><em>)</em>
Answer:
divide 14/4.5=3.11
multiply 3.11 * 9 = 27.99 round off to 28.00
