Answer:
x < 3
Step-by-step explanation:
-12 < -7x -5 +14
add -5 and 14: -12 < -7x + 9
minus 9 from both sides: -7x > -21
divide both sides by -7: x < 3
the sign flips when you divide
Given that
[tex]\frac{8-3\sqrt{2} }{2} = a+b\sqrt{2}[/tex]
Find a and b
Answer:
a = 4, b = - [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given
[tex]\frac{8-3\sqrt{2} }{2}[/tex] = a + b[tex]\sqrt{2}[/tex] ( multiply both sides by 2 to clear the fraction )
8 - 3[tex]\sqrt{2}[/tex] = 2a + 2b[tex]\sqrt{2}[/tex]
For the 2 sides to be equal , then
2a = 8 ( divide both sides by 2 )
a = 4
and
2b = - 3 ( divide both sides by - 2 )
b = - [tex]\frac{3}{2}[/tex]

2 (x + 1) = -200 x= 66
2x + (-3) = = (-23) x=
X - 3 = (-9) x=
(-3x) - 5 = 16 x=
-4 (y - 2) = 12 x=
4x = (-28) x=
2x + 9 = (-15) x=
X + 5 = 18
3 (x+ 5) = 18
3x + 5 = 18
2 (x + 5) = 16
3 (y + 200) = 3000
20.8 = 4 (z + 1.1)
3 (x + 4.5) = 36
9 = 3 (x + 2)
2x + 16 = 50
14 = 2 (x + 3)
5x + 2 = 17
Answer:
---------
Step-by-step explanation:
x-3= -9
x= -9/ 3
x= -3
( -3x)-5 =16
-3x = 16+5

A running track has two semi-circular ends with radius 25m and two straights of length 87.6m as shown.
Calculate the total distance around the track rounded to 1 DP.
The total distance around the track is 332.2 meters
How to calculate the total distance?The complete question is in the attached image
The given parameters are:
Radius, r = 25 m
Length, l = 87.6 m
Start by calculating the circumference of the two semi-circular ends using:
[tex]C = 2\pi r[/tex]
So, we have:
C = 2* 3.14 * 25
Evaluate
C = 157
The total distance around the track is then calculated as:
Total = 2l + C
This gives
Total = 2 * 87.6 + 157
Evaluate
Total = 332.2
Hence, the total distance around the track is 332.2 meters

A carpenter wants to make a ladder, but he want to calculate the required wood for it. The distance between each step is 1 foot Price of wood is 500 per foot calculate the price of wood as well. Example: Input: Output: Enter the length of ladder in foot: 25 Enter the width of ladder in foot: 2 Required wood in foot: 98 Cost of wood is: 49000
Answer:
Part A
The required wood for the ladder is 98 feet
Part B
The cost of the wood is 49,000
Step-by-step explanation:
Part A
The dimensions of the ladder to be made with wood are;
The distance between each step of ladder = 1 foot
The length of the ladder = 25 feet
The width of the ladder = 2 feet
The required wood = 2 × 25 feet/rail + 2 feet/steps × 24 steps = 98 feet
The required wood for the ladder = 98 feet
Part B
The cost of the wood = 500/foot × 98 feet = 49,000
The cost of the wood = 49,000
In ABC with the right angle at vertex C, sin(b)= (26)/8. What is sin(a)?
Answer:
We can use the Pythagorean theorem and properties of sines, cosines, and tangents to solve the triangle, that is, to find unknown parts in terms of known parts.
Step-by-step explanation:
Pythagorean theorem: a2 + b2 = c2.
Sines: sin A = a/c, sin B = b/c.
Cosines: cos A = b/c, cos B = a/c.
Tangents: tan A = a/b, tan B = b/a.

Answer:
Step-by-step explanation:
"100" or any constant at the end of the equation is r² (radius squared). So, the radius is 10.
the center of the circle is (-6, 2)
the equation template of a circle is (x -h)² + (y - k)² = c
(h,k) is the center of the cirlce.

Answer:
Implicit Form: 4x + y - 52 = 0
Step-by-step explanation:
8x + 2y = 104 => Move constant to the left and change the sign
8x + 2y - 104 = 0 => Divide both sides of the equation by 2

write an explicit formula for an, the nth term of the sequence 11,2,-7
Answer:
[tex]a_{n}[/tex] = 20 - 9n
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 2 - 11 = - 7 - 2 = - 9
This indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 11 and d = - 9 , then
[tex]a_{n}[/tex] = 11 - 9(n - 1) = 11 - 9n + 9 = 20 - 9n
