Answer:
EQUATION IS GIVEN BELOW.
Step-by-step explanation:
let the number be 'x'
now,
x+12 =36
or, x=36-12
therefore,x=24
Tangent = opposite/adjacent
tangent = 15 / 8
If opp = 15 and adj = 8 then
hypotenuse^2 = 15^2 + 8^2
hypotenuse^2 = 225 + 64
hypotenuse^2 = 289
hypotenuse = 17
secant = hypotenuse / adjacent
secant = 17 / 8
secant = 2.125
Your answer would be
A. Adding 7x to both sides of the equation
And in doing so, you'd start your first step to having "like terms" on "like sides"
by having all "x's" on the right side of your equivalent sign "="
Hi
7 = 14.70
15= X
so : X = 15*14.70 /7 = 31.5
15 liters of petrol cost 31.5
