Answer:
x= 1
QS = 10 cm
QRS = 40cm
Step-by-step explanation:
4x + 1 = 5x
x= 1 cm
QS = 4x + 1 + 5x
= 9x + 1
= 9 + 1
= 10cm
QRS perimeter
QS + RQ + RS but ( RQ = RS)
= 10 + 15 + 15
= 40cm
Answer:
5.5 = x
Step-by-step explanation:
c(x)=x-2
3.5 = x-2
Add 2 to each side
3.5+2=x-2+2
5.5 = x
25/45=(5∗5)/(5∗9)=5/9
5/9 is the answer.
