Answer:
= Sh. 2281.50
Step-by-step explanation:
Area of the path;
(126 × 2.5 ) + (2.5 × (48 - (2.5×2)
= 315 + (2.5 × 43)
= 315 + 107.5
= 422.5 m²
But; the cost of graveling is sh 5.40 per square meter
Therefore; The cost of graveling the whole path;
= 422.5 × 5.40
<u>= Sh. 2281.50</u>
Answer:
the awnser would be a(g(x)=3x2
(1)
10(1+3x)=-20
Cross multiply.
10+30x=-20
Isolate x on one side. So you would subtract 10 on each side. and one side will cross each other out. leaving you with,
30x=-20-10
Subtract 10 from -20.
30x=-30
Divide each side by 30 to get x.
30x÷30=-30÷30
Therefore,
x=-1
(2)
-5x-8(1+7x)=-8
Cross multiply -8(1+7x)
-5x-8-56x=-8
Isolate all x's on one side. So you would add 8 on each side. and one side will cross each other out. leaving you with,
-5x-56x=-8+8
Add 8 to -8.
-5x-56x=0
Subtract -56x from -5x
-61x=0
Divide each side by -61
-61x÷-61=0÷-61
Therefore,
x=0
I would say A (7) but I’m not 100% sure.
