Answer:
53
Step-by-step explanation:
At first,
- 7 = 9 + x
By subtracting 9 from both sides, we get
-7-9=9+x-9
-16=x
Now,
By substituting the value of x in -3x + 5 , we get
-3x + 5
-3×(-16)+5
48+5
53
For a) the pattern rule goes 12+(12x2)=36 36+(12x4)=84
So the pattern rule is double the number and then times it by twelve to get to the next answer
4x+y = 20
3x+y = 2
4x+y-3x-y = 20-2
x = 18
3x+y = 2
3.18 + y = 2
54 + y = 2
y = -52
Answer:
22.7604763 degrees
Step-by-step explanation:
Note that the answer is NOT 20 degrees.
She adjusted the ramp to half the original <em>incline</em>
Therefore we have tan 40 = x = 0.839099631.
We want an incline of y degrees where tan y = x/2 = 0.839099631/2 = 0.419549815
Taking the arctan of both sides, we get
y = arctan(0.419549815) = 22.7604763 degrees
