-3x + -15 = 12
x = __
Answer:
x=9
Step-by-step explanation:
alright so first we eliminate the -15 and to do that we add 15 on both sides:
-3x-15+15=12+15
-3x=27
Now we divide 3 on both sides to make the equation equal to x
[tex] \frac{-3x}{-3} = \frac{27}{-3} [/tex]
x=9

In the isosceles triangle ABC
AB=AC
angle B = (3x 32)º
angle C =(87-2x)"
Work out the value
of x.
Answer:
x = 4.5
Step-by-step explanation:
Angle B = angle C because it is an isosceles triangle.
3x32 = 87-2x
96 = 87-2x
reduce:
9 = 2x
x = 4.5
An isosceles triangle is one with two equal-length sides. The value of x is 11.
What is an isosceles triangle?An isosceles triangle is one with two equal-length sides. It is sometimes stated as having exactly two equal-length sides, and sometimes as having at least two equal-length sides, with the latter form containing the equilateral triangle as a particular case.
Since in an isosceles triangle, the angle made by the equal sides and the base are equal, therefore, we can write,
∠B = ∠C
3x + 32 = 87 - 2x
3x + 2x = 87 - 32
5x = 55
x = 11
Hence, the value of x is 11.

csc^-1 4.25 to degrees
9514 1404 393
Answer:
13.609°
Step-by-step explanation:
The csc^-1 function is the arccosecant function. It gives the angle whose cosecant is given. If we let A represent that angle, your statement is ...
A = csc^-1(4.25)
It is used to solve the relation ...
4.25 = csc(A)
__
Some calculators can give you the value directly (see attached). Most cannot. In any event, you need to make sure the angle mode for the calculator is set to degrees.
When your calculator does not have the csc^-1 function, you can make use of the trig identity ...
csc(x) = 1/sin(x)
In the above equation, this becomes ...
4.25 = 1/sin(A)
sin(A) = 1/4.25 . . . . . solve for sin(A)
All scientific and graphing calculators will have the inverse sine (arcsine) function.
A = sin^-1(1/4.25)
A ≈ 13.609° . . . . . . . calculator mode in Degrees
_____
Additional comment
For inverse functions, especially inverse trig functions, I find it useful to read them as ...
csc^-1(x) ⇒ "the angle whose cosecant is x"
sin^-1(x) ⇒ "the angle whose sine is x"
This reminds me that the value it gives is an angle (degrees or radians), and the argument it takes is a pure number (one with no units).

Q4 - Exam prep: Missing values
Audrey measures all 7 pencils in her pencil case and writes the first 6 lengths down.
12.4 cm, 12.6 cm, 13 cm, 13.4 cm, 13.5 cm, 13.3 cm
Audrey calculates the mean length of all 7 pencils to be 13.1 cm.
Find the length of the missing pencil.
cm
[2]
Answer:
the missing pencil length is 13.5 cm
Step-by-step explanation:
The computation of the length of the missing pencil is shown below:
Let us assume the missing pencil be x
Now
(12.4 cm + 12.6 cm + 13 cm + 13.4 cm + 13.5 cm + 13.3 cm + x) ÷ 7 = 13.1 cm
(78.2 cm + x) ÷ 7 = 13.1 cm
78.2 cm + x = 91.7 m
So, x would be
= 91.7 cm - 78.2 cm
= 13.5 cm
hence, the missing pencil length is 13.5 cm

7x-3= -24 what is x and how do you find it?
Answer:
x = -3
Step-by-step explanation:
7x - 3 = -24 (Given)
7x - 3 + 3 = -24 + 3 (Added 3 on both sides by using the addition property of equality)
7x = -21 (Simplified)
7x/7 = -21/7 (Divided 7 on both sides by using the division property of equality)
x = -3 (Simplified)
Therefore, x = -3.
Answer:
x= -3
Step-by-step explanation:
You do the opposite.
So,
-24 +3
= -21
-21/ 7
= -3
Therefore, the answer is -3

Isaac and Albert spot a hot air balloon flying at a low altitude. They decide to calculate its height by standing 400 feet apart on a level surface and measuring the angle of elevation to the balloon. From
Albert, the balloon was at an angle of elevation of 62°and from Issac its was 48º. Determine the height of
the balloon above the ground to the nearest foot.
Answer:
144 feet to nearest foot.
Step-by-step explanation:
Let the distance between Albert and the point on the ground that the balloon is directly above be x feet Then for Isaac the distance is 400 - x feet
So we have 2 right angled triangles and:
tan 62 = h/x
tan 48 = h / (400- x) where h is the height of the balloon.
From the first equation x = h / tan 62 so plugging this into the second one:
tan 48 = h / ( 400 - h/tan 62)
h = 400 tan 48 - h tan 48 tan 62
h + h tan 48 tan 62 = 400 tan 48
h ( 1 + tan48 tan62) = 400 tan48
h = 400 tan 48 / (1 + tan 48 tan 62)
= 143.8 feet.

George is required to produce 500 frames for an art gallery. He spent $100 on the wood required for all these frames. He also spent $50 in polishing all the final frames. He rented two floors of an art gallery for about $700. What selling price should George charge the art gallery if he wants to break even?
Answer:
George should charge 1.70$ for each frame to break-even.
Step-by-step explanation:
Variable cost for the frames:
Wood + polishing = $100 + $50 = $150
Variable cost per frame would be:
$150/ 500 = $0.30
The fixed cost of the operation is $700.
George has to make 500 frames.
Fixed cost / (Selling price per unit – variable cost per unit) = 500
$700 / (Selling price per unit - $0.30) = 500
700 = 500 (Selling price per unit – 0.30)
700 = 500 * Selling price – 500 * 0.3
700 = 500 * Selling price – 150
(700 + 150) / 500 = Selling price
850 / 500 = 1.7
Caroline is planning on reducing her working schedule and only work 7 hours each day for 4 days a week work out the percentage reduction in Caroline's earnings if she decides to go ahead with her plan
The percentage reduction in Caroline's earnings if she decides to go ahead with her plan is 30%.
How to calculate the value?Since Caroline works 8 hours each day for 5 days a week and she's earns £11 per hour. The amount earned for the week is:
= (80 × 5 × £11)
= £440
When she is planning on reducing her working schedule and only work 7 hours each day for 4 days a week. The amount will be:
= (4 × 7 × £11)
= £308
The percentage reduction will be:
= Difference on amount / Old amount × 100
= (440 - 308) /440 × 100
= 132/440 × 100
= 0.3
= 30%

the tiles on cathy's bathroom floor are square shaped and each tile covers an area of 90 square inches. simplify an expression to represent the side length of each tile.
Answer:
[tex]\huge\boxed{\sf L = 3\sqrt{10} }[/tex]
Step-by-step explanation:
Area of a square tile = 90 square inches
Let the side length of tile be "L"
Condition:
Area = 90
L * L = 90
L² = 90
Taking sqrt on both sides
L = √90
L = 3√10

Answer:
C. x = 3
Step-by-step explanation:
8x - 8 = 2x + 10
get the x on it's own
8x - 8 + 8 = 8x
2x + 10 + 8 = 2x + 18
8x = 2x + 18
8x - 2x = 6x
2x + 18 - 2x = 18
6x = 18
now divide each side by 6
6x / 6 = x
18 / 6 = 3
x = 3
X=3
Explanation
8x-8=2x+10
6x=18
x=3
