Answer:

x = 3

Step-by-step explanation:

First we know that you have to do parenthesis because, of PEDAS so the problem would look like 4x - (x-5)+3=-1. You would first because, it is always 1 outside of parenthesis it would now look like 4x - x +5 +3=-1. Next you would combine like term 3x +8 = -1. Next you would subtract 8 from both sides 3x = 9. Next you would divide 3 from both sides. x=3

Therefore your answer would be x = 3

Jayson baked a pan of cornbread for a family dinner. He cut the cornbread into equal size pieces. At the end of the dinner, ther
VARVARA [1.3K]
If 1/6 of the pan was left and there were 2 pieces left you just need to set 1/6 equal to 2/some number, this allows you to say that 1/6=2/x --> x/6=2-->x=12. My explanation might be a little poor since this becomes fairly fundamental later on but hopefully it helps.

In ΔUVW, the measure of ∠W=90°, WV = 39, UW = 80, and VU = 89. What ratio represents the cosine of ∠U?
kumpel [21]

Answer:

cos ∅ = 80/89

Step-by-step explanation:

As required from the question the picture below represent a triangle UVW . The angle W = 90°. The sides WV = 39 , VU = 89 and UW = 80. The triangle forms a right angle triangle .

Such triangle one can establish trigonometric relationship using the SOHCAHTOA principle.

The question requested us to find the ratio that represent the cosine of  ∠U.

The ∠U is represented as ∅ .

Therefore,

cos ∅ = adjacent/hypotenuse

adjacent = 80. The adjacent side is the non hypotenuse side that is next to the given angle.

hypotenuse = 89 . Hypotenuse is the longest side of a right angle triangle and it opposite the right angle.  

cos ∅ = adjacent/hypotenuse

cos ∅ = 80/89

In order to win a quiz contest, olga must score more than 400 points. She earns 12 points for each right answer, and loses 4 poi
Ket [755]

The inequality that represents the number of right answers (r) and wrong answers (w) Olga can give to win the contest is:  3r-w>100

<u><em>Explanation</em></u>

Number of right answers is  r and number of wrong answers is  w

Olga earns 12 points for each right answer and loses 4 points for each wrong answer.

So, total points earned for r right answers =12r

and total points lost for w wrong answers =4w

That means, <u>her score will be</u>:  (12r-4w) points.

In order to win the quiz contest, Olga must score <u>more than 400 points</u>. So, the inequality will be.......

12r-4w>400\\ \\4(3r-w)>400\\ \\  3r-w>100
