Answer:
x= -7, y= 12
Step-by-step explanation:
To find the value of x and y, first label the 2 equations.
2x +y= -2 -----(1)
x +y= 5 -----(2)
(1) -(2):
2x +y -(x +y)= -2 -5
2x +y -x -y= -7 <em>(</em><em>expand</em><em> </em><em>bracket</em><em>)</em>
x= -7
subst. x= -7 into (2):
-7 +y= 5
y= 5 +7 <em>(</em><em>+</em><em>7</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
y= 12
A/b =2 and
a=8
b=4
3b + a2
3(4)+8 x 2
12+16
28

Answer:
b
Step-by-step explanation:
80% +15% +5%=100
15/100= 0.15
5/100= 0.05
therfore
0.15 + 0.05 = number of flaws
=0.20
