Answer:
1) x=3/2y+1/2
2)x=-1/3y+-5/3
Step-by-step explanation:
1)
Let's solve for x.
2x−3y=1
Step 1: Add 3y to both sides.
102x−3y+3y=1+3y
2x=3y+1
Step 2: Divide both sides by 2.
2x/2
=
3y+1/2
x=3/2y+1/2

Answer:
the value of P(B) = 1/3
Step By Step Explaination:
If A and B are two independent events, then P(A and B)=P(A) x P(B) (i)
Put all values in (i), we get
1/6= 1/2 x P(B)
P (B) = 2/6
P(B) = 1/3
Hence The Value of P(B) = 1/3.

Step-by-step explanation:
The Acosta family went out to dinner. The price of the meal was $79.85. If the tip was 15%. How much money did the Acosta family pay for the meal, including tip?
A) $91.83
B) $67.87
C) $11.98
D) $94.85
Answer:
the Smith family pay for the meal = $ 36.39Step-by-step explanation:
The Smith family went out to dinner . The price of the meal was $ 29.85 .
The sales tax was 6 % of the price of the meal .
LEts find sales tax amount sales tax amount = price of meal *
sales tax 6 % ( 0.06 ) = 29.85 * 0.06 = 1.791 sales tax amount = 1.791
Price of the mean with sales tax = 29.85 + 1.791 = 31.641
The tip was 15 % of the meal and the sales tax now we find out tip amount for 31.641 15 % is 15 / 100 = 0.15
Tip amount = 31.641 * 0.15 = 4.74615
Now we add the top amount with 31.641 31.641+ 4.74615 = 36.38715
the Smith family pay for the meal = $ 36.39

1. h = b + 5
when b = 7,

when o = 36,
36 = 4b
=> 36/4 = b
=> 9 = b
You have $3,000 in savings account that pays 2.5% interest, compounded monthly. What is future value in 4 years?
Answer:
[tex]\$4453.52[/tex]
Step-by-step explanation:
Principal amount (P) = $3,000
Rate of interest (R) = 2.5%
Time period (T) = 4 years
Future value in 4 years = [tex]P(1+\frac{R}{100})^{4T}[/tex]
Put [tex]P=3000\,,\,R=2.5\,,\,T=4[/tex]
Therefore,
Future value in 4 years = [tex]3000(1+\frac{2.5}{100})^{4(4)}=3000(1.025)^{16}=\$4453.52[/tex]

Answer:
57.8º
Step-by-step explanation:
According to the law of sines [tex]\frac{sinA}{a}[/tex] = [tex]\frac{sinb}{b}[/tex] = [tex]\frac{sinc}{c}[/tex].
In this triangle we have two sides with two of their angles.
Let's make 8 cm side a with 38º as its angle, and 11 cm side b with x as its angle.
[tex]\frac{sinx}{11}[/tex] = [tex]\frac{sin38}{8}[/tex]
Now we multiply both sides by 11 to get rid of the denominator on the left.
sinx = [tex]\frac{11sin38}{8}[/tex]
To find x, we use inverse sine.
x = sin⁻¹ (11sin38/8)
Plug this into a calculator, and you will get 57.837.
Round this to 57.8º
Hope this helps!

Answer:
5 percent is the difference between 10 and 5 because the ramp needs to be 5 percent but most average wheelchair ramps are 10 degrees and there is a 5 degree differance
Step-by-step explanation:
hope this helps
Answer:
5° is the difference
Step-by-step explanation:
One of the ramps is 5° and the other one is 10°. The difference between these 2 ramps is of 5°.
10 - 5 = 5
And as you can see in the image, the mid ray is what divided both of the other rays, and its right in the middle. Both rays combined gives you 10° as it shows, and half of 10 is 5. So the difference will be of 5°

Answer:
a) ∠XWY = 53°
b) ∠XZY = 106°
Step-by-step explanation:
The relationship between the central angle and the arc length is that they're equal. So, if arc XY = 106° this means that ∠XZY = 106°.
The relationship between the central angle ∠XZY and the inscribed angle ∠XWY is that the inscribed angle is half the value of the central one.
So, ∠XWY= ∠XZY/2 = 106/2 = 53
Results:
∠XWY = 53°
∠XZY = 106°

What is meant by decimal number?Integer and non-integer numbers are often expressed using the decimal numeral system.
Decimals are a type of number in algebra that have a whole number and a fractional portion separated by a decimal point. The decimal point is the dot that separates the whole number from the fractional part of the number.
The term "decimal" refers to the base-10 number system, which is arguably the most widely used. The ten single-digit numbers that make up the decimal number system are 0 through 9, or just 1, 2, 3, 4, 5, 6, and 7. 10 is the number that follows 9. 20 comes follows the number 19, and so on.
