Answer:
x = -18
Step-by-step explanation:
Distribute: 3*5x = 15x ; 3*-6 = -18 ; 6*2x = 12x ; 6*-12 = -72
15x - 18 = 12x - 72
Add 18 to both sides: 15x = 12x - 54
Subtract 12x from both sides: 3x = -54
Divide both sides by 3: x = -18
Answer:
x= 17.666666...
Step-by-step explanation:
3(5x - 6) = 6(2x - 12)
(3 times 5x , 3 times -6) (6 times 2x, 6 times - 12)
15x-18 = 12x -72 (multiply insides)
-12x -12x (remove 12x from right side)
3x-19 = -72 (product)
+19 = +19 (add 19 left side to remove it)
3x = 53 (product)
x = [tex]\frac{53}{3}[/tex] (divide)
x= 17.666666... (answer)
x = 17.67 (if simplify)

SALE
Taal buys a jacket in the sale.
It has 15% off and he pays £42.50.
The original price of the jacket was £
He saved £
Answer:
£50 ; £7.50
Step-by-step explanation:
Given that:
Discount on sale, d = 15%
Amount paid = £42.50
Hence the relation to obtain the amount paid goes thus ;
Amount paid = (1 - d) * original amount
Let original amount = x
42.50 = (1 - 0.15)x
42.50 = 0.85x
x = 42.50 / 0.85
x = £50
Amount saved :
£(50 - 42.50) = £7.50

mZAOC = 104°
mZAOB = 7x + 30°
mZBOC = 9x + 42°
Find mZBOC:
Answer:
The answer is 60°
Step-by-step explanation:
From looking at the problem we know that mZAOB and mZBOC make up angle mZAOC.
We also know that mZAOC is 104°
This means that the two other angles have to make up 104°
To figure out mZBOC,
First, you can subtract 30 and 42 from 104.
We do this because it allows us to focus on the variables.
104-30-42=32
Next, we can look at the variables and the coefficients and see that in order for 7x and 9x to make 32, x has to equal 2.
7(2)+9(2)=32
Now that we know what x equals we can substitute it into the equation for mZBOC.
9x + 42°
9(2) + 42°
60°
Thus, mZBOC equals 60°

A normal body temperature for a human is approximately 98° Fahrenheit. What is this temperature in degrees Celsius? Round your answer to the nearest tenth.
Answer:
37°C
Step-by-step explanation:
The normal body temperature of a human is 98°F. To convert it into Celsius we know the realtion between Celsius and Farenheight as ,
➳ C/5 = F -32/9
➳ C/5 = 98 - 32/9
➳ C/5 = 66/9
➳ C = 66/9 × 5
➳ C = 36.66 °C ≈ 37°C
Hence the body temperature in Celsius measure is 37°C .What was the shortest measurement?
Length of insects (in inches)
Answer:
[tex]1\frac{1}{2}[/tex] inches
Step-by-step explanation:
The shortest measurement is the smallest number with a x over it. In this case, the smallest one is [tex]1\frac{1}{2}[/tex] inches.
Question
A county fair attracts large crowds of people every year. Ideally, 280,000 people come to the fair, but this value can vary by
as many as 8,500 people. What are the maximum and minimum numbers of people expected to attend the fair?
Answer:
the maximum amount of people would be 288, 500 and the minimum would be 271,500
Step-by-step explanation:
basically if the average number is 280,000 all we have to do is add and subtract 8,500 to find the maximum and minimum
There could be up to 288.500 persons present, with a minimum of 271,500.
What is an expression?Mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
The average number is 280,000 all we have to do is add and subtract 8,500 to find the maximum and minimum.
Maximum = 2800000 + 8500 = 288,500
Minimum = 271,500 - 8500 = 263000
Therefore, there could be up to 288.500 persons present, with a minimum of 271,500.

O A. 5
B. 100
O c. 10
O D. 75
Answer:The Answer is C
Step-by-step explanation:
The value of the constant in the equation below is 100. So, the correct option is (C).
What is Height?Height also known as elevation is defined as the vertical distance either between the top and bottom of something or between a base and something above it. It refers to something measured vertically high or low.
Height is body measurement usually measured in feet (feet) + inch (in) and centimeter (cm) where these are length measurements, so the SI unit will be meter.
Height equation: H= C/W
where, H is the height, C is the constant and W is the width.
We choose a point given in the graphic, I will choose (4,25), which means that when W=4 and H=25 . We use this to find the constant. So
25=C/3
C= 100
Thus, the value of the constant in the equation below is 100. So, the correct option is (C).

Answer:
x = 44
y = 22
Step-by-step explanation:
✔️Find x:
Reference angle = 60°
Hypotenuse = x
Opposite side length = 22√3
Applying the trigonometric FUNCTION, SOH, we have:
Sin 60 = opp/hyp
Sin 60 = (22√3)/x
x × Sin 60 = 22√3
x = (22√3)/Sin 60
x = (22√3)/(√3/2) (sin 60 = √3/2)
x = 22√3 × 2/√3
x = (22√3 × 2) / √3
x = (44√3) / √3
x = 44
✔️Find y:
Reference angle = 60°
Hypotenuse = x = 44
Adjacent length = y
Applying CAH, we have:
Cos 60 = adj/hyp
Cos 60 = y/44
44 × Cos 60 = y
44 × ½ = y (cos 60 = ½)
22 = y
y = 22
Answer:
x=44,y=22
Step-by-step explanation:
sin 60=22√3/x
x=22√3/sin60=44
sin30=y/x
y=sin30×44=22

The interest of $4000 in 2 years is 500. what is the simple interest rate?
Answer:
0.0625/year or 6.25%/year
Step-by-step explanation:
Simple interest formula:
I = Prt where I = interest (final) amount, P = principal (initial) amount, r = interest rate, t = time (years)We are given these values:
I = $500 P = $4000 t = 2 yearsWe want to find r, the simple interest rate.
Substitute these known values into the formula.
I = Prt 500 = (4000) × r × (2) 500 = 8000r 0.0625 = rThe simple interest rate is 0.0625, aka 6.25% per year.

If a rocket travels 68,732 milometers in 3 hours, what is it's speed?
a) 23,000 Km/hr
b) 23,000 hr/km
c) 22,910 hr/km
d) 22,911 km/hr
Answer:
v = 0.0229 km/h
Step-by-step explanation:
Given that,
Distance, d = 68,732 milometers = 0.0687 km
Time, t = 3 hours
We need to find the speed of the rocket. The speed of an object is given by :
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{0.0687}{3}[/tex]
v = 0.0229 km/h
So, the speed of the rocket is 0.0229 km/h.

The required value of x = 12 and the side length of the triangle is 12 units. which is determined by Pythagoras's theorem.
What is Pythagoras's theorem?
Pythagoras's theorem states that in a right-angled triangle, the square of one angle is equal to the sum of the squares of the other two sides.
The given triangle is a right-angled triangle.
As per Pythagoras's theorem,
⇒ a² + b² = c²
Here a = 16, b = x and c = 20
Substitute the values in the formula,
⇒ 16² + x² =20²
⇒ 256 + x² = 400
⇒ x² = 400 - 256
Apply the subtraction operation,
⇒ x² = 144
⇒ x = √144
⇒ x = 12
Therefore, the required value of x is 12 units.

Answer:
1) Z = 3.17
2) 4.69 or √22
3) X = 42°
4) X = 60°
Step-by-step explanation:
1) (4)(8+4) = (Z)(Z+12)
48 = Z² + 12Z
Z² + 12Z -48 = 0
(Z +15.17)(Z - 3.17) = 0
Z = 3.17
2) (2)(11) = Y²
y² = 22
Y = 4.69 or √22
3) 180° - 139° = 41°
41° = 1/2(40° + X)
41° = 20° + 0.5X
21° = 0.5X
X = 42°
4) X = 1/2(240°-120°)
X = 1/2(120°)
X = 60°
