Hi,
Let Sydney's age be x.
Devaughn=(x-15)
x+(x-15)=37
x+x-15=37
2x-15=37
2x=37+15
2x=52
x=52/2
x=26
Sydney is 26 years old.
Hope this Helps you.
$322.56
You change 28% to .28 then multiply that with $448=$125.44
Then you minus that from $448=$322.56
That would be the last choice. Opposite meaning different sign
Answer:D
Step-by-step explanation: the equation is written is slope- intersect form were -2 is the y intersect. the coordinate of the y intersect is (0,-2). the number in front of the x is the slope which is 1/2. so the answer is D.
6 + (10 x 2) = 26 = (12+1)*2
