Simplify the equation for S please

Mathematics
1 answer:
Alla [95]3 years ago
6 0
This questions expects us to SOLVE for S, i.e. express the the value of S in terms of other variables, and simplify the answer, if necessary.

We need s to be the subject (on the left hand side), so we need to isolate s.
C=(1/3)m(s+b)
First step, cross multiply to rid of numerical fractions.
C/1=(m(s+b))/3   ->  3C=m(s+b)

If there is a multiplier that does not contain s, divide both side by the multiplier.
3C/m = (m/m)(s+b)   ->   3C/m = s+b

We're nearly done.  We need to isolate s, so subtract "extra" terms from the side containing s, i.e. subtract b from both sides:
3C/m - b = s + b  -b   -> 3C/m-b = s

We almost there, but customary practice is to put s on the left-hand side of the equal sign, so just swap sides:
3C/m-b = s   ->   s=3C/m - b
and that's the answer:

s=3C/m - b

Problem 24

<h3>Answer: w = 120</h3>

-----------------

Work Shown:

We have an isosceles triangle. The angles opposite the congruent sides are congruent. These are the base angles each 30 degrees. The missing angle is w. The three angles add to 180

(angle1)+(angle2)+(angle3) = 180

30+30+w = 180

60+w = 180

60+w-60 = 180-60 ... subtract 60 from both sides

w = 120

======================================================

Problem 25

<h3>Answers:</h3><h3>x = 6.5</h3><h3>y = 5</h3>

-----------------

Work Shown:

The angle marks are all the same, so the three angles are congruent to one another. We consider this an equiangular triangle. Any equiangular triangle is also equilateral, meaning all three sides are the same length.

So,

2x-5 = 8

2x-5+5 = 8+5 ... add 5 to both sides

2x = 13

2x/2 = 13/2 ... divide both sides by 2

x = 6.5

and also,

y+3 = 8

y+3-3 = 8-3 ... subtract 3 from both sides

y = 5

Solve for x in the diagram below.<br> (2x + 30°<br> 40°<br> 40°<br> т
solniwko [45]

Answer:

x = 35°

Step-by-step explanation:

assuming that the straight line at the bottom of the figure is actually a straight line, that means all the angles along that straight line must add up to 180 °

i.e.

40 + (2x+30) + 40 = 180

40 + 2x+30 + 40 = 180

110 + 2x = 180  (subtract 110 from both sides)

2x = 180 - 110

2x = 70

x = 35

Simple geometry please help<br><br> Find KL. Round to the nearest hundredth.
vivado [14]

Answer:

KL ≈ 1.94

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos48° = \frac{adjacent}{hypotenuse} = \frac{JL}{KL} = \frac{1.3}{KL} ( multiply both sides by KL )

KL × cos48° = 1.3 ( divide both sides by cos48° )

KL = \frac{1.3}{cos48} ≈ 1.94 ( to the nearest hundredth )
