I am taking 7I+x to mean 71+ x.
Answer: y=1.837
Step-by-step explanation:
Step 1
Let y is inversely proportional to 7I+x be mathematically be written as
y ∝ 1/7I+x
Introducing our proportionality of constant , K we have that
y ∝ 1/7I+x
y =K 1/7I+x
y= K/ 7I+xh
Step 2
so when x= 8, and y =2, k becomes
y= K/ 7I+x
k= y x (7I+x)
=2 x (71 + 8)
2x 79
=158
when x= 15, y =?
y= K/ 7I+x
y= 158/ 71 + 15
y=158/86
y=1.837
B) corresponding angle theorem
Answer:
90.8
Step-by-step explanation:
w = 80 + 5.4t (fill in your variable t, the number of months)
w = 80 + 5.4(2) (Combine parentheses first)
w = 80 + 10.8 (Add the two together)
w = 90.8 (Your answer)
I hope this helped :)
Answer:
Step-by-step explanation:
Sammie is x,,,, Jennie is 9 years younger than him. So, Jennie ( y) = x-9
According to second condition eq is
(X-5) = 4(y-5)
Place the value of y in eq 2
You will find x= 17
Put x in eq 1
Y = 8
