Answer:
2. 4a+2c = 5000
4. a + c = 1600
Step-by-step explanation:
What is x
First you use distributive property
60x+70=26
Next subtract 70 on both sides which gives you -44
60x=-44
Then you divide 60 into -44 which will give you -1.36__36 is repeathing
so X=-1.36 repeading
2-5 x 1/2 = 0.2 (Length x Width)
X^2 + x(x - 5) - x + 7
x^2 + x^2 - 5x - x + 7
2x^2 - 6x + 7
convert 50ft to inches which is 600
then divide 600 by 75 = 8 rotations
