There is only one solution in the given equation -y2 − [-5y − y(-7y − 9)] − [-y (15y + 4)] = 0. In solving this problem, apply first PEMDAS (parenthesis, exponents,multiplication, division, addition, subtraction). Then equation will transform into -y2+5y-7y2-9y+15y2+4y=0. Combine terms with same power and achieve 7y2=0. Divide both sides with 7 and perform square root of zero. Since the root is zero, we have one solution of the given equation which is y=0.

First, 5/3 = 1.6
21 x 1.6 = 34.99999999
But, when I put it in a calculator, the 1.6 was repeated so:
Round 34.99999999 to 35

Answer:
3
Step-by-step explanation:
52.1 x 26.4 to find the total area equals 1375.44
1375.44 / 500 = 2.75088
since you can’t buy parts you round tot he next whole number making the answer 3
If they are similar, their sides are proportional. Compare 3/5 ratio is the same as x-4/x
