To solve for x, in the given equation;
we need to divide both sides of the equation by 2;
2x divided by 2 is equal to x, while 22 divided by 2 is 11.
So;
Answer:
95
Step-by-step explanation:
Being a sum of two elements that include units and tens, we can make the sums of the units first, and then add the tens together.
So, if we have 45+50, we can first separate the units: 5 + 0 =5
Then, we separate the tens: 4+5=9
Now, we only join the sums of the units and tens, and that will be the end result. 95
Answer:
Part A
Add Like terms
6x + 2x + 13 = 3x - 12
8x + 13 = 3x - 12
get x on the left side
5x + 13 = -12
Subtract 13 from both sides
5x = -13 -12
5x = -25
Divide both sides by 5
x = -5
Step-by-step explanation:
Answer:
Slopes of perpendicular lines are the opposite reciprocal of each other. If you know the slope of one line, just multiply it by -1 and flip the fraction to find the perpendicular slope.
Answer:
x=121.5
Step-by-step explanation:
Angle at the center =2 times angle at the circumference
Total angle at the center =360
Angle left=360-117=243
243/2=121.5
