Answer:
7
Step-by-step explanation:
28 ÷ 16 = 1.75
1.75 × 4 = 7
The way I did it is by finding out how much bigger 28 is than 16 by dividing and then I multiplied the answer (1.75) by 4 to get the bigger answer. The problem is showing you that the triangles are the same just different sizes.
The answer as a mixed number is 1 7/25
The answer as a decimal is 1.28

Answer:The integers are -13, -12 and -11.
Step-by-step explanation:
Let the four numbers be n, n+1, n +2, and n+3
Therefore (n )+ (n+1 )+(n+2) + (n +3) = -46
4n + (1 +2+3) = -46
4n + 6= -46
Subtract 6 from both sides to get the value of n
4n +6 - 6= -46 -6
4n = -52
Divide both sides by 4
n = -52/4
n = -13
Therefore, n + 1 = -13 + 1= -12
n + 2= -13 + 2 = -11
The integers are -13, -12 and -11.
