Answer:
D. 8.8
Step-by-step explanation:
As the pythagorean theorem.
A² + B² = C²,
5.4 × 5.4 + 7 × 7 = C²,
29.16 + 49 = C²,
78.16 = C²,
8.8 ≈ C
Answer: D and E
Step-by-step explanation:
To find this answer we want to get x by itself in the equation.
6x + 4 < 22
6x < 18
x < 3
So according to this the value of x has to be less than 3.
You can check your answer by substituting the values in for x.
6(0) + 4 < 22
4 < 22 is True
6(2) + 4 < 22
16 < 22 is True
6(3) + 4 < 22
22 < 22 False!
Answer:
32/4= 8 (there is a factor of 8 between x and y at all times)
128/8 = 16 (divide y by 8 to find out what x is.
x= 16 when y= 128
