Answer:
x=4
Step-by-step explanation: Let's solve your equation step-by-step.
3x+2=14
Step 1: Subtract 2 from both sides.
3x+2−2=14−2
3x=12
Step 2: Divide both sides by 3.
3x
3
=
12
3
x=4
Answer:
n = 18
Step-by-step explanation:
(2n) and (n + 18) are vertically opposite angles and are congruent, then
2n = n + 18 ( subtract n from both sides )
n = 18
Answer:
16.5 ft
Step-by-step explanation:
The formula for the volume of a triangular prism is V = (1/3)(base area)(height).
We can solve this formula for (height):
3V
(height of triangular prism) = -----------------
base area
In this particular case,
3(264 ft³)
(height of triangular prism) = ----------------- = 16.5 ft
48 ft²
Answer:
Step-by-step explanation:
1) So -8+2v<2, 2v<10, v<5. That means that at "5" on the axis, you'll draw a circle that's <em>not</em> filled in (because it's <5, not
5) and then draw a box-y thing to the left. Sorry, can't really describe it, but if you look at the picture attached, you'll understand
2) -12m-8
-5m-7m, so -12m-8
-12m, -8
0. This one doesn't have a variable... so you can't really graph it?
Answer:
320m
Step-by-step explanation
a rectangle has four sides, two pairs of identical sides. So two sides are 16. So that adds up to 32. Perimeter is all sides added together. so it has to add up to 72. 72 minus 32 is 40, so two of the sides have to be 40. Area is length times width, so 16 times 20, which is 320.
