You have to multiply the number of people times the number of cookies they are each supposed to get
So, 28 x 3 = 84 cookies
X+ y = 10
2x = 2y+4
2x/2 = 2/2y+4/2
x = y + 2
x+y = 10
y+2+y=10
2y + 2 = 10
2y +2-2 =10-2
2y = 8
2y/2 =8/2
y = 4
x + y =10
x + 4 =10
x +4-4 =10-4
x = 6
Check
2x = 2y +4
2(6) = 2(4) +4
12 = 8+4
12= 12
Answer:
8
Step-by-step explanation:
4 + (x + 1)
4 + 4
8

<em>or</em>
2(5)+2-3
Step-by-step explanation:
if a = 5 and b=2,
you add it into the expression.
2a + b -3 --> 2(5) + 2 - 3
all you have to do is replace the letters with the (given) numbers.
then, solve.
2(5) = 10
2-3= 1
10+1 =11
the answer is 11.
