Answer:
x = 8.5
Step-by-step explanation:
In this question, we are to calculate the value of x.
To calculate this, we shall be utilizing one of the important properties of parallelogram.
This property is that opposite angles of a parallelogram are equal.
This means that mQSR = mSPQ = 4x + 90
Now to finally calculate x, we make use of another important parallelogram property which is that angles of parallelogram which faces each other are supplementary.
This means that they add up to be 180
Since mQSR faces mQRS
This means that;
4x + 90 + 9x -20 = 180
13x + 70 = 180
13x = 110
x = 110/13 which is approximately 8.5
Answer:
write the percent divided by 100
Step-by-step explanation:
1) write the percent divided by 100.
2) if the percent is not a whole number, multiply both top and bottom by 10 for every number after the decimal point.
3) reduce (simplify) the fraction.
Add 7 to both sides.
13+7=
20
3x-3*4=-15
3x-12=-15
3x=-15+12
3x=-3
x=-3/3
x=-1
