Plug in 7 for x:
2(7) + 3 =
Solve:
14 + 3 = 17
7 is a true answer for x
Answer: u = 8
Step-by-step explanation:
We need to get the variable by itself first. In this case the variable is u.
u is really just mutliplied by -4, (-4 x u). In this situation, the opposite of multiplication is division. So, we need to divide -4u by -4 on each side.
-32 = -4u
-32/-4 = -4u/-4
8 = u
u = 8
Answer:
D. 2
Step-by-step explanation:
soh cah toa rule
sine equals opposite over hypotenuse,
cosine equals adjacent over hypotenuse, and
tangent equals opposite over adjacent
csc is 1/sin which is hypotenuse over opposite
if csc is -√5/2 then
hypotenuse is -√5
opposite is 2
3rd quadrant on a graph is bottom left
both x and y values are negative
hypotenuse means its a triangle
pythagorean theorem
a^2 + b^2 = c^2
a^2 + 2^2 = (-√5)^2
a^2 + 4 = 5
a = 1 = adjacent
tangent equals opposite over adjacent
tan is 2 / 1 which is 2
third quadrant means it's still positive
because tan is positive in quadrant 3

You can find the answer for any conversion questions like this
write the values first.
47.85ft - x
3.3ft- 1m
Then cross multiply..
47.85=3.3x
then do opposite operation the variable side
and divide.
47.85÷3.3=14.5m
Answer:
Range 40
Mean 99.4
Step-by-step explanation:
There is a mode since the number 104 shows up twice.
The median is not 100 because it is 102.
The range is 40 because 120 is the largest number and 80 is the smallest number.
So 120 - 80 = 40
The mean is 99.4 because when you add all the numbers up and then divide it by 10 you get 99.4
