-7.
5x-3 = -15
-15-4\4= -16
-16 + 9 = -7

Using with PEMDAS: First, using with parentheses, you do 6-2= 4. Now the problem should be 9+5×(-3)-4÷4. Then, exponents, but in this problem, there are no exponents so we can skip that. Now, M (Multiplying), if you see a multiplication problem, just do it. 5×(-3)= -15. If the two signs are the same, then the answer will be a positive. But the two factors are different so they have to be negative. 9+(-15)-4÷4, should be the problem. Now, D (Division), you get 4÷4= 1. The problem should be 9+(-15)-1. This should be A, or Addition. 9+(-15)= -6. So, (-6)-1. The last one is subtraction so get (-6)-1 equals -5. The answer should be a -5.

(Remember, if you see several multiplication problems, do it from left to right. This goes for all of the PEMDAS strategy.)

Find the value of y.

Try this option:
1. the sides of the biggest triangle are 16; x and √(16²-x²); the sides of the smallest triange are x;5 and y. The smallest triangle ~ the biggest triangle. Using the property of the similar triangles:
$\frac{x}{5} = \frac{16}{x}, \ then \ x= \sqrt{80}$
2. according to the Pyphagorean theorem (in the smallest triangle):
$y= \sqrt{ \sqrt{80^2} -5^2} = \sqrt{55}$

answer: y=√55.

The answer is 58, because 2/5 is equal to 0.4, and 0.4 multiplied by 145 is 58.
