Answer:
1) 4-(-6) = 10
2) -10.3-(-7.79)= -2.51
3) -4+6 1/2= 2 1/2
4) -10.2+4.38= 5.82
5)
Step-by-step explanation:
1) A double - equals positive so change to
4+6=10
2) adding positive to negative makes it less negative
3) just change positions -4 from 6 1/2
4) makes it less negative
5) sorry I hat fractions can't do it
Answer:
It is 1/11
Step-by-step explanation:
Apply the rule a/c +- b/c = a+-b/c
=8-7/11
=1/11
If you would like to solve the inequality 12 * p + 7 > 139, you can do this using the following steps:
12 * p + 7 > 139
12 * p > 139 - 7
12 * p > 132 /12
p > 132/12
p > 11
The correct result would be p > 11.
Answer:
105.46 feet
Step-by-step explanation:
We know all three angles (60, 90, and 30), as well as one side, which is adjacent to the 60 degrees. We want to find the side opposite to the 60 degree angle. To do this, we can use tangent, utilizing both opposite and adjacent.
Using tan, we can say that tan(60) = x/58, with x representing the height of the lighthouse (minus 5, because Santos is 5 feet tall and he is measuring the angle from the top of his head). Multiplying both sides by 58, we can get that 58 *tan(60) = x = 100.46. Add 5 to that to get 105.46 feet as your answer.

Given: 
Find: 
Solution: In order to simplify the inequality we can simply add 4 to both sides which would isolate x.
<u>Add 4 to both sides</u>
Therefore, an inequality that would be equivalent to the one that was provided in the problem statement is x < 13.
