Answer:
2 2/5
Step-by-step explanation:
5y + 7 = 52
5y = 52 - 7
5y = 45
y = 9

=

=
3(x+12) = 2 x 42
3x + 36 = 84
3x = 84 - 36
3x = 48
x = 16
Angle H = 180 - 52 - 36 = 92
Answer:
The value of y for x = 45 is 120 .
Step-by-step explanation:
Given as :
Let The variables y and x are proportional to each others
I,e y ∝ x
Now , y = k x
So, for x = 3 , y = 8
I.e 8 = k × 3 ........1
∴ k = 
<u>Similarly </u>
for x = 45 , y = k × 3
I.e y = k × 45 ..........2
Now, putting the value of k in eq 2
So, y =
× 45
I.e y = 
Or, y = 8 × 15
∴ y = 120
So, for x = 45 , y = 120
Hence The value of y for x = 45 is 120 . Answer
Answer:
Step-by-step explanation:
ok so this is what you would do
5s+3t=30
-1(2s+3t=-3)
which will become
5s+3t=30
-2s-3t=3
which turns into
3s = 33, s=11
