Answer:
X=18
Step-by-step explanation:
you can find what the missing angle is by subtracting 92 from 180 since its a straight line. After putting in the missing angle you can easily solve for 2X which is 36 and then divide by 2 and get 18.
Answer:
2635
Step-by-step explanation:
the first two stand for 1000
so
2000
is the first part
the second numeral stands for 100
there are 6 of them
so
600
is the second part
the third numeral stands for 10 and there are 3 of them
thus
30
is the third part
there are 5 lines so the last part is 5
so your answer is 2635
Step-by-step explanation:
To find the perimeter of something, we add all of the measurements of the sides together.
A rectangle has 4 sides, this means we must double the algebraic hints given to us.
If we add them all up together it will look like this:
x-9+x-9+3x-4+3x-4=138
If we simplify it by collecting the like terms:
8x-26=138
We add 26 onto 138
8x=164
To find out what x equals, we divide by 8:
164÷8= 20.5
Answer:
x=20.5cm
x-9 is 11.5
3x-4 is 57.5
