This translates to "a number" is greater than 45. All you have to do now is translate these words into an algebraic statement. Basically, you replace "a number" with the variable which it is defined for, and you use the "greater than" symbol to show that the variable is greater than the value of 45.
If you have a problem like:
4x+2y=20
2x+2y=16
You would subtract
4x-2y=20
-2x+2y=16
You would get the new problum
2x=4
You now want to divide the 2 on both sides to solve for x
x=2
Now that you've solved for X you want to solve for y. So use substitution to solve for y. You would want to substatute the x for the 2 in either of the problums. I'll use the first one.
4(2)+2y=20
You first want to multiply te 4(2) you would get a new problum.
8+2y=20
Now you want to subtract the 8 on both sides.
2y=12
The last step to solve for y is to divide the 2 on both sides.
Y=6
So your answers would be
x=2
y=6

Answer:
x ≈ 9.8
Step-by-step explanation:
The relevant trig relation is ...
Tan = Opposite/Adjacent
Filling in the given values gives ...
tan(59°) = x/5.9
Multiplying by 5.9, we have ...
x = 5.9×tan(59°) ≈ 9.8
X = 105
The circle is 360, so add the two numbers that are already present there together,. The rest two side are the same, so use 2x, x for one side, so two for two side.
85 + 65 + 2x = 360
150 + 2x = 360
2x = 210
x = 105
In order to get the figure, you have to plot it.
