Answer:
57 + 3x
Step-by-step explanation:
“More than” is called “+”.
“Times” is called “×”.
Greg's score will be represented as “x”.
Note: “3x” also means “3 × x”.
25*2=50
10*5=50
so 2 packets of envelopes and 5 packets of stamps
30 * 0.30 = 9
30 + 9 = 39
30 increased by 30% = 39
Bottom right! You are correct. :)
Answer:
24.25 in²
Step-by-step explanation:
s = (a + b + c)/2 = (8 + 13 + 7)/2 = 14 in
s - a = 6, s - b = 1, s - c = 7
so
the area = ![\sqrt{14\times6\times1\times7}=24.25](https://tex.z-dn.net/?f=%5Csqrt%7B14%5Ctimes6%5Ctimes1%5Ctimes7%7D%3D24.25)
