Combine like terms. Like terms are completely the same excluding coefficients.
6x+5=10
Subtract 5 from both sides
6x=5
Divide bith sides by 6
x=5/6
Final answer: B
Answer:
- 17. A. 180 in²
- 18. B. 234 in²
Step-by-step explanation:
#17
<u>Total surface area is:</u>
- A = 8(3*2 + 6*2) + 2(3*6) = 180 in²
Correct option is A
#18
<u>Total surface area is:</u>
- A = 2(9*9) + 4(2*9) = 234 in²
Correct option is B
Answer:
The correct answer is D) (-2, -1)
Step-by-step explanation:
In order to solve this system of equations, start by multiplying the entire first equation by 2. Then add the two equations together. This will get the y's to cancel and allow you to solve for x.
-4x + 2y = -10
3x - 2y = 12
---------------------
-x = 2
x = -2
Now that we have the value for x, we can find y by plugging the x value into either equation.
-2x + y = -5
-2(2) + y = -5
-4 + y = -5
y = -1
The median is the middle number of the data plot. Since there 30 numbers, there isn't a exact middle. To find the median you must add the two middle number then divide by 2.
In this case you must add 87 and 88 which gives 175.
Then divide 175 by 2 which gives 87.5
87.5 is the median
the answer would be the third choice which is N(0, z)
