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
Answer:
what I got is a= 5/2
Step-by-step explanation:
remove the parentheses then you calculate then you move the terms then calculate the like terms and divide both sides.
I hope this helps
Answer:403+179 582
Step-by-step explanation:
Step-by-step explanation:
h²=o²+a²
a²=8²+5²
a²=64+25
a²=89
a=√89
a=9.433
To one decimal place it is 9.4
for b,
h²=o²+a²
17²=b²+12²
289=b²+144
289-144=b²
145=b²
b=√145
b=12.041
To one decimal place it is 12.0
