Answer:
$10 each week
Step-by-step explanation:
The boxes sum is equal to 40.
(x-2)+(x-2)+(x-2)+(x-2)+(x-2) = 40
5x-10 = 40
5x=50
x =50/5
x=10
We have
f(x)=(x-7)/(x²<span>-7x-8)
resolving the quadratic equation
using a graph tool-------- > see the attached figure
x=-1 x=8
therefore
</span>(x-7)/(x²-7x-8)=(x-7)/[(x+1)*(x-8)
the answer is -1 and 8
Answer:
x = 7
y = 2
Step-by-step explanation:
In the above question, we are given 2 equations which are simultaneous. To solve this equation, we have to find the values of x and y
x + 3y = 13 ........ Equation 1
x - y = 5...........Equation 2
From Equation 2,
x = 5 + y
Substitute 5 + y for x in Equation 1
x + 3y = 13 ........ Equation 1
5 + y + 3y = 13
5 + 4y = 13
4y = 13 - 5
4y = 8
y = 8/4
y = 2
Since y = 2, substitute , 2 for y in Equation 2
x - y = 5...........Equation 2
x - 2 = 5
x = 5 + 2
x = 7
Therefore, x = 7 and y = 2
