Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Let x = cost of a loaf of bread ; y = cost of an egg
Dwayne :
1 loaf of bread and 6 eggs :
X + 6y = 4.45 - - - (1)
Sheila :
X + 12y = 5.65 - - - (2)
From (1);
X = 4.45 - 6y
In (2):
(4.45 - 6y) + 12y = 5.65
4.45 + 6y = 5.65
6y = 5.65 - 4.45
6y = 1.2
y = 0.2
From X = 4.45 - 6y:
X = 4.45 - 6(0.2)
X = 4.45 - 1.2
X = 3.25
Cost of a loaf of bread = $3.25
Coat of an egg = $0.2
4.8(10^9)/(1.6(10^3))
Pertinent quotient rule for similar bases with exponents...
(a^b)/(a^c)=a^(b-c) so what you really have is:
(4.8/1.6)(10^(9-3))
3(10^6)
3X10^6
Answer:
A = 217
B = 45
Step-by-step explanation:
A+B = 262
A - B = 172
A = 172 + B
172 + B + B = 262
2B = 90
B = 45
A = 172 + (45)
A = 217
HOPE THIS HELPS!!!!
1/3 and 1/2 common denominators are the number 6 ,1/3x2=2/6 and 1/2 x3=3/6 so 2/6 divide by 2 =1/3 and 3/6 divide by 3 =1/2 I hope this helps
