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]

what is 1/ 3 (x – 10) = -4
(please help )
Answer:
1/3(x-10)=-4
We move all terms to the left:
1/3(x-10)-(-4)=0
Domain of the equation: 3(x-10)!=0
We add all the numbers together, and all the variables
1/3(x-10)+4=0
We multiply all the terms by the denominator
4*3(x-10)+1=0
Wy multiply elements
12x(x+1=0

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
Some systems of inequalities can have no solution.
Answer:
Yes, that is true.
Step-by-step explanation:
The bounded regions of the two inequalities do not overlap, so there is no solution set. However, the existence of parallel lines does not necessarily indicate that there is no solution, it just means that there is the possibility of no solutions.

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.

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 =

same letter vs. same letter =

normal number vs. normal number =

Step-by-step explanation:
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.

"Eight less a number is less than or equal to seventeen"
Answer:
we don't know the exact value of "a number" so we can assign it the letter value x
so we know that x-8 is less than or equal to 17
you would solve this the same way you would solve any other equation so
x is less than or equal to 25
Find the distance, c, between (–4, –3) and (2, 1) on the coordinate plane. Round to the nearest tenth if necessary.
Answer:
d=√((x_2-x_1)²+(y_2-y_1)²)
d=√((2-(-4))²+(1-(-3))²)
d=√(6²+4²)
d=√36+16
d=√52
d=7.21110255...
d=7.2
Step-by-step explanation:
d=7.2
The distance between the points on the coordinate plane is 7.2 units.
What is coordinate geometry?Coordinate geometry is the study of geometry using the coordinate points. It provides a link between geometry and algebra through line graphs and curves.
For the given situation,
The points are (x1, y1) be (–4, –3) and (x2, y2) be (2, 1)
The formula for the distance between points,
[tex]d=\sqrt{(x2-x1)^{2}+(y2-y1)^{2} }[/tex]
On substituting the above points,
⇒ [tex]d=\sqrt{(2-(-4))^{2}+(1-(-3))^{2} }[/tex]
⇒ [tex]d=\sqrt{6^{2}+4^{2} }[/tex]
⇒ [tex]d=\sqrt{52}[/tex]
⇒ [tex]d=7.211[/tex] ≈ [tex]7.2[/tex]
Hence we can conclude that the distance between the points on the coordinate plane is 7.2 units.
