Answer:
x=23
m<1=161
m<2=19
Step-by-step explanation:
7x+x-4=180
8x+4=180
8x=184
x=23
m<1: 7(23) = 161
m<2: (23-4) = 19
35% because 35% of 80 is 28
To get the answer we can use proportion
86 --------------45%
x ---------------- 100%
Now cross multiply
x*45%=86*100
45x=8600 /:45 (divide both sides by 45)
x=191.11 - its the answer
