Answer:
65
Step-by-step explanation:
128-63=65
first, spread the parenthesis. y+2=1/2x-1.5
second, add 1.5 to both sides. y+3.5=1/2x
third, multiply by 2. 2y+7=x
if you are solving for y, do not do the third step, instead, subtract by 3.5. y=x-3.5
hope this helps!
ANSWER: x=2y+7 or y=x-3.5
<h2>Answer:</h2><h2>Option A is the answer </h2><h2>let a be no of adult and b be the no of children</h2><h2>total money made by park =$55157</h2><h2 /><h2>Given equation </h2><h2>$19 per adult =19a</h2><h2>$9.5 per children=9.5c</h2><h2>total people =3806</h2><h2>19a+9.5c=3806</h2><h2>a+c=55157</h2><h2 /><h2 /><h2>FOLLOW MEH✌✌✌✌✌✌</h2>
First you simply have to substitute 2 in replace of all the a's, and -2 in replace of all of the b's
4((2)2+2(-2))
Then you want to follow the order of operations, PEMDAS (Parantheses-Exponent-Multiplication-Division-Addition-Subtraction), and multiply within the parantheses.
4(4+(-4))
Next you will add within the parantheses (So add the 4 and -4 together)
4(0)
Lastly multiply
0
Your answer is 0
Hope this helps!
