Answer:
Step-by-step explanation:
el número es 4,5
es una ecuación lineal:
2x+18=27
2x=9
x=9/2
x=4,5
we can have a triangle and we know that there are two angles.
30º and a 45º + 105 =180º angle. applying the sides.
therefore if we have the whole triangle completed we have a constant triangle.
so it tell us we can you’se SOH CAH TOA
we can varrify what kind of triangle we are using.
for example if we were to use Sin I would do
Sin 30/ 2 = sin of 105º/ A = sin=45º/ B
if you would want to solve for sin 30/2 and sin 105, then we solve.
or Sin 30/2 and Sin 105 as well.
with your calculator use sin= 30=.5 and use sin 105º a divide by 1.5 on both sides 1.5= A /sin 105º * 1.5 answer would be 3.86. a is = to 3.86 (Not the answer)
$400.72 - This is how it’s done.
First get rid of the last set of () by doing distributive property with the - sign
x^2 + 2x -1 - x^2 + 2x -1
=4x - 2
The inequality that shows the temperature in Melbourne is 20°F ≤ x ≤ 100°F
<h3>What is an
inequality?</h3>
An inequality is an expression that shows the non equal comparison of two or more variables and numbers.
Let x represent the temperature in Melbourne.
The highest temperature ever recorded there was 109°F, hence x ≤ 109°F.
Also, the lowest temperature ever recorded there was 20°F, hence x ≥ 20.
From both statements:
20°F ≤ x ≤ 100°F
The inequality that shows the temperature in Melbourne is 20°F ≤ x ≤ 100°F
