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:
the answer is 7
Step-by-step explanation:
7+(-3)=4
7-3=4
hence shown so missing number is 7
The threes are in the hundreds place and ten places. The relationship is by 10x
Answer:
Step-by-step explanation:
Rewrite X^2+22x=31, leaving space after the "22x:"
X^2+22x = 31
The coefficient of x is 22. Take half of that, obtaining 11.
Square this result: 11^2 = 121.
Write in "+121 -121" after the x term:
X^2+22x + 121 - 121 = 31
Rewrite X^2+22x + 121 as
(x + 11)^2 -121 = 31
Add 121 to both sides:
(x + 11)^2 = 152
Take the square root of both sides:
x + 11 = ±√152 = ±2√38
Finally, x = -11 ±2√38.
This is "solution by completing the square"
