Answer: Equations (b) and (e) do not have solutions
Step-by-step explanation: b) The x cancels out (-10x + 35) = -10x + 318; 35 = 318???? NO. e) 3(x + 2) + 1 = x + 2(4 + x); 3x + 7 = 3x + 8. The x cancels out again.
The other s can be solved for x.
1 Yes 2. Yes
Step-by-step explanation:
they are similar because in problem one each side is related by a factor of 3
in problem 2 each side is related by a factor of 2.
Answer:
Step-by-step explanation:
We have to find the relative frequency for each event.
The relative frequency of a event is the number of times the event event happened by the total number of events.
There are 16+18+19+19 = 72 events.
X can be 4,5,6 or 7.
We have that
Answer:
28.46
Step-by-step explanation:
Use a^2+b^2=c^2 to find height
Then use the area formula bh/2 to find area :))
Answer:
The answer is 1st point, 1/2×22.0×23.1
Step-by-step explanation:
You can let XY be the base and XZ be the height of the triangle. Then, by using the formula of the area of triangle, A=1/2×base×height to find the expression.
