Answer:
Final answer is x=90, 
Step-by-step explanation:
Given equations are:
-x-4y=37 ...(i)
-2x-4y=-53 ...(ii)
multiply (ii) by -1
2x+4y=53 ...(iii)
Add (i) and (iii)
x=90
plug value of x=90 into (i)
-x-4y=37
-90-4y=37
-4y=37+90
-4y=127

Hence final answer is x=90, 
Answer:
The new ribbon is 511.85 meter long.
The total cost Rs. 6142.2
Step-by-step explanation:
First of all we convert all lengths to the standard unit that is meter.
0.5 km =500 meter
1005 cm = 10.05 meter
1800 mm = 1.8 meter
total length in meters
500+10.05+1.8= 511.85
total cost at the rate of Rs. 12 per meter will be
511.85×12=6142.2
Answer:
3t
Step-by-step explanation:
7t-3t+4t-5t
Combine like terms
7t -3t = 4t and substitute back into the expression
4t +4t -5t
4t+4t = 8t and substitute back into the expression
8t - 5t
3t
Answer:
Step-by-step explanation:
It's y = x^2, not y = x2. The graph of y = x^2 is a parabola with vertex (0, 0) and which opens up.
The graph of y = (x + 5)^2 has the same shape as that of y = x^2, but has been translated 5 units to the left.
