Answer:
<em><u>0=x</u></em>
Step-by-step explanation:
First you need to get the variable on one side of the equation
7-x+3=9x+10
+x +x
7+3=10x+10
Now we can combine like terms on the left side of the equation
10=10x+10
Subtract 10 from each side
10=10x+10
-10 -10
0=10x
Divide by 10
0 =10x
/10 /10
<em><u>0=x</u></em>
Answer: x=-6
Steps
distribute
2-3(x+4)=8
2-3x-12=8
Subtract the numbers
2-3x-12=8
-10-3x=8
Rearrange terms
-10-3x=8
-3x-10=8
Add ten to both sides
-3x-10=8
-3x-10+10=8+10
Simplify
(add the numbers)
-3x=18
Divide both sides by the same factor
-3x=10
(Write this part in a fraction)
-3x/-3 = 18/-3
Last step simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
X=18/-3 (18 over -3 write it as a fraction)
So that leaves your answer to
X=-6
Answer:
a= 126
b= 54
c= 126
d= 54
e= 126
f= 54
g= 126
Step-by-step explanation:
To find a you would subtract 54 from 180 which would give you 126
Since a and b are another linear pair they would also add up to 180.
Then you move to c which is a linear pair with 54 so it is 126.
Because a and g are alternate interior angles they are congruent and they you continue with the same process for the first and check by seeing if the angles would be obtuse or acute to see if the angle measures would be correct.
Answer:
The answer to your question is x = 3.356 cm
Step-by-step explanation:
This is a right triangle so we can use the Trigonometric functions to solve this problem.
Data
Ф = 40°
Adjacent side = 4 cm
Opposite side = x
Process
1.- We must know the lenght of the opposite side so we must use the tangent to solve it.
tangent Ф =
2.- Solve it for Opposite side
Opposite side = tanФ x Adjacent side
Opposite side = tan 40° x 4
Opposite side = 0.839 x 4
Opposite side = 3.356
Opposite side = x = 3.356 cm
