A+b= 1246
a-b=1234 => a= b+1234
2b+1234= 1246/-1234
2b= 12/:2
b= 6
a=b+1234
a= 6+ 1234
a= 1240
Answer:
3 cans
Step-by-step explanation:
area 1=.9×.3=.27 m²
area2=1/2×0.5×0.5=0.25/2=0.125 m²
total area=0.27+0.125=0.395 m²
area of 6 signs=0.395×6=2.370 m²
total cans reqd.=2.37/1=2.37
so 3 cans are reqd.
Answer:
x = 74
Step-by-step explanation:
2 * x + 19 = 167
2x + 19 = 167
So we have to subtract 19 from both sides
2x = 148
Divide both sides by 2
x = 74
