Please help.
Answer:
[tex]a = \frac{5b+w-2}{15}[/tex]
Step-by-step explanation:
[tex]w=5(3a-b)+2\\w-2 =5(3a-b)\\w-2 = 15a - 5b\\w-2+5b = 15a \\5b+w-2= 15a\\a = \frac{5b+w-2}{15}[/tex]

USE ARITHMETIC OR GEOMETRIC SEQUENCE TO SOLVE.
Lisa wants to get a new phone. An iPhone 12 is $800 while an iPhone 8 is $600. If the iPhone 12's price goes down by 10% each year and the iPhone 6's goes down by 5% each year, Which phone would be the cheapest for Lisa to get after three years?
Answer:
iPhone 12!!!!!!!!!!!!
Answer:
The iphone 8
Step-by-step explanation:
To find the nth term of a geometric sequence we have the following equation
ar^(n-1)
where a is the first term
r the is the common ratio
n is the term
we can see that the first term for the iphone 12 is 800, the common ratio is .9 (1-.1), and we need the third term
Therefore the price of an iphone 12 after 3 years is
800*.9^(3-1)
which is 648
The iphone 8's first ter is 600 and the common ratio is .95 (1-.05)
using the same equation
600*.95^(3-1)
which is 541.5

A building casts a 32m shadow when the sun is at an angle of 30 degrees to the vertical. How tall is the building to the nearest meter?
Answer:
16m tall
Step-by-step explanation:
Distance casted by the shadow = 32m = hypotenuse
Angle of elevation = 30 degrees
Required
Height of the building = opposite
Using the SOH CAH TOA identity
sin theta = opp/hyp
sin 30 = x/32
0.5 = x/32
x = 0.5 * 32
x = 16m
Hence the building is 16m tall

What is the value of x?
Answer:
35 degrees
Step-by-step explanation:
Answer:
x = 35 degrees.
Step-by-step explanation:
If two lines intersect each other, then the angles across from each other will equal to one another. Because the angle across from x is 35 degrees, we know that x equals 35 degrees as well.

What is the factored form of this expression?
18x2 − 50
Answer:
_14
Step-by-step explanation:
step1 18×2 -50
step2 18×2 =36_50
step3 36_50=_14
Answer:
2(9*x-25)=18×2-50
Step-by-step explanation:
the answer is in the problem since we know 1 times anything will stay the same. so just divide the other integers by 2 and put the problem in parentheses.

What relationship do you notice between the squares of
the right triangle?
The special relationship that exists between the squares of the lengths of the sides of a right triangle is known as the Pythagorean Theorem. The Pythagorean Theorem states that the sum of the squares of the lengths of the legs of a right triangle equals the square of the length of the hypotenuse.

Answer:
1. 100 1. 150 1. 1
2.45 2. 800
Step-by-step explanation:
1. 25% * 400 = 0.25 * 400 = [tex]\frac{1}{4}[/tex] * 400 = 100
2. 50% * 90 = 45
1. 75% * 200 = 0.75 * 200 = 3/4 * 200 = 150
2. 10% * 8000 = 0.1 * 8000 = 800
1. 5% * 20 = 0.05 * 20 = 1
