Given that 3x – 8y = 39
Find y when x = 3
Give your answer as an improper fraction in its simplest form.
Answer:
- [tex]\frac{15}{4}[/tex]
Step-by-step explanation:
Given
3x - 8y = 39 ← substitute x = 3 into the equation
3(3) - 8y = 39
9 - 8y = 39 ( subtract 9 from both sides )
- 8y = 30 ( divide both sides by - 8 )
y = [tex]\frac{30}{-8}[/tex] = - [tex]\frac{15}{4}[/tex]

A car is traveling at a steady speed. It travels 2 1/3 miles in 3 1/2 minutes. How far will it travel in 25 minutes? In 1 hour?
Answer:
https://i.pinimg.com/originals/50/3f/9a/503f9a49a2faa03f7db90f090eea6bff.gif
Step-by-step explanation:
Answer:
Given:
A car travels 2 1/3 miles in 3 1/2 minutes.
We need to find the distance travelled in 25 minutes, in 1 hour.
So, 2 1/3= 7/3 and 3 1/2 = 7/2
Let's convert them into decimals by dividing them completely.
So, we will get 2.33 miles and 3.5 minutes.
So now we have that 2.33 miles are covered in 3.5 minutes.
Now we need to know the distance covered in 1 minute.
So, 2.33/3.5=0.67
So now we have in one minute 0.67 miles are covered.
Now distance covered in 25 minutes will be:
0.67*25 = 16.75 miles
Now distance covered in one hour:
1 hour = 60 minutes.
So, 0.67*60 = 40.2 miles
So we have distance covered in 25 minutes-16.5 miles and in 1 hour- 40.2 miles.
1. g(x) = f(x) - 7
how do u solve these?
Answer:
g' (×)=f
Step-by-step explanation:
g (×)=f×-7
g' (×)= d÷d× (f×-7)
d÷d×(f+g)=d÷d×(f)+d÷d=(g)
g' (×)=d÷d×(f×)-d÷d×(7)
g'(×)=f-d÷d×(7)
g'(×)=f-0
g'(×)=f

A major storm has winds speeds that are at least 110 miles per hour.Write and solve an inequality that describes how much greater these wind speeds are than the slowest hurricane
Answer:
x ≥ 36 miles per hour
Step-by-step explanation:
The speed of a major storm is at least 110 miles per hour while the speed of the slowest hurricane is at least 74 miles per hour.
Let x represent how much greater these wind speeds are than the slowest hurricane. Therefore:
x ≥ 110 miles per hour - 74 miles per hour
x ≥ 36 miles per hour
This means that the winds speed must be 36 miles per hour greater than the slowest hurricane.

Answer:
13cm
Step-by-step explanation:
The pythagorean theorem states that, for right triangles, [tex]a^{2} +b^{2} =c^{2}[/tex]. Using this equation, we can solve for the hypotenuse.
a = 12cm
b = 5cm
c = hypotenuse
[tex]12^{2} +5^{2} =c^{2}[/tex]
[tex]144+25=c^{2}[/tex]
[tex]\sqrt{169} =c[/tex]
13 = c
Answer:
13
Step-by-step explanation:
a^2+b^2=c^2
12^2+5^2=c^2
144+25=c^2
169
square root of 169=13
13=c
distribute then combine like terms : 0.2(3b-15c)
Answer:
0.6b - 3c
Step-by-step explanation:
Multiply 0.2 and 3b
0.2 x 3b = 0.6b
Then multiply 0.2 and 15c
0.2 x 15c = 3c
We can't add these, 3c and 6b because they have different letters.
different letter vs. different letter =
don't add
different letter vs. normal number like 5 =
dont add
same letter vs. same letter =
add
normal number vs. normal number =
add
This all goes the same for dividing, subtracting, and multiplying

A line passes through the point A (-2,-5) and has a slope of -9. Using the point-Slope formula, express the equation of the line in slope intercept form.
Answer:
y = -9x -23
Step-by-step explanation:
Point-slope formula gives you
y -(-5) = -9(x - (-2))
y + 5 = -9(x + 2)
y + 5 = -9x - 18
y = -9x -23

Question 6 of 10
A triangle has sides measuring 8 inches and 12 inches. If x represents the
length in inches of the third side, which inequality gives the range of possible
values for X?
A. 8< x < 12
B. 4 < x < 20
C. 4 sxs 20
D. 8 sxs 12
SUBMIT
Answer:
the answer is b
Step-by-step explanation:
The possible inequality for x is 4 < x < 20.
The correct option is (B).
What is inequality?Inequality, A declaration of an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to. Either questions or theorems can be used to express inequality problems, and both can be solved using methods similar to those used to solve equations. The triangle inequality, for instance, stipulates that the length of the remaining side of a triangle is more than or equal to the sum of the lengths of any two of its sides.
We are given that,
A triangle has sides measuring 8 inches and 12 inches. If x represents the length in inches of the third side
8+12=20
so it has to be less than 20, and 12-8=4,
So it has to be more than 4,
So the only answer that makes sense is
4<x<20.
Therefore, option B is correct.
