-8/5 converted to a decimal is -1.6
-8/5 can make -1 plus the remainder
Hope this helps :)
Answer:
y = 3
x = - 3
Step-by-step explanation:
First we represent "x" through "y"
y = x + 6
x = y - 6
Then we substatute this value instead of "x" in the other formula, and so we get...
y = - 2x - 3
y = - 2(y - 6) - 3
y = - 2y + 12 - 3
3y = 9
y = 3
Now that we know "y" we can find out "x" by doing...
x = y -6
x = 3 - 6
x = - 3
By applying the trigonometry ratio, SOH, the angle that the ladder makes with the building is calculated as: 17.5°
<em><u>Recall:</u></em>
- Trigonometry ratios that can be used to solve a right triangle are: SOH CAH TOA.
- SOH represents: sin ∅ = Opp/Hyp
- CAH represents: cos ∅ = Adj/Hyp
- TOA represents: tan ∅ = Opp/Adj
The diagram attached below depicts the problem given.
∅ = x
Opp = 15 ft
Hyp = 50 ft
- Thus, applying the trigonometry ratio, SOH, we have:
sin x = 15/50
x =
x = 17.5°
In conclusion, by applying the trigonometry ratio, SOH, the angle that the ladder makes with the building is calculated as: 17.5°

Answer:
$5.25, $7.20, 21 dollars for 4 pizzas
Step-by-step explanation:
21/4 = $5.25 per pizza
36/5= $7.20 per pizza
$5.25 is cheaper, thus 21 dollars for 4 pizzas is a better deal
