Answer:
90m
Step-by-step explanation:
AB = 18m
BC = AB + 9 = 18 + 9 = 27m
Perimeter = 2(AB + BC)
= 2( 18 + 27)
= 2 x 45
= 90m
Answer: x= 63, y= 27
Step-by-step explanation:
x and angle measure 117 are a linear pair. They sum to 180.
117+x= 180. Subtract 117 from both sides.
x = 63
Looking at the relationship of x and y, the diagram shows that the two together equal 90 degrees. Add the two together and set equal to 90.
63+y= 90. Subtract 63 from both sides.
y = 27
To find the value of x we need to use the INVERSE OPERATION of addition which is subtraction. Then we will check our work. lets do it:-
x + 19 = 13
x = ?
13 - 19 = x
<span>13 - 19 = -6</span>
x = - 6
CHECK OUR WORK:-
x + 19 = 13
x = -6
-6 + 19 = 13
We were RIGHT!!
So, x = -6

Answer:
r = c -km÷m
Step-by-step explanation:
C=( r+k) m (multiple the m with the letters in the brackets)
rm + km= c (cross the km over the equal sign and it will be a negative)
rm= c- km (then divide everything by my)
rm÷m = c - km÷ m
r = c- km÷ m
Answer:
So 60% of this unknown number is 28
Let this unknown number be n
60/100 × n = 28
0.60 × n = 28
n = 28/0.6
n = 46.7
To the nearest wholw number is 47
So there are 47 votes in total
