Answer:
y=16, x=24
Step-by-step explanation:
First simplify: x-(1/2x+4)=8
Isolate x for 1/2x-4=8
Add 4 to both sides:
1/2-4+4=8+4
Simplify :1/2=12
Multiply both sides by 2:
2*1/2x=12*2
Simplify:
x=24
Substitute x=24:
y=1/2*24+4
1/2*24+4=16
1/2*24=12
12+4
Add the numbers: 12+4=16
y=16
The solutions to the systems of equations are:
y=16,x=24

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 =
dont add
same letter vs. same letter =
add
normal number vs. normal number =

This all goes the same for dividing, subtracting, and multiplying

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

In NOP,the measure of p=90 the measure of n=59 and PN=7.4 feet.Find the length of OP to the nearest tenth of a foot
Answer:
12.3 feet
Step-by-step explanation:
Given
<P = 90 degrees
<N = 59 degrees
PN = 7.4 feet
Required
OP
NO = hypotenuse
OP = adjacent
PN = opposite = 7.4
Using SoH CAH TOA identity
tan <O =PN/OP
tan (180-149) = 7.4/OP
tan 31 = 7.4/OP
OP = 7.4/tan 31
OP = 7.4/0.600
OP = 12.3 feet (to the nearest tenth)
What is the inverse of y = 3* ?
Streets in the city can be represented by the equations in the given table. Use the equations to find the type of quadrilateral that the streets form. Justify your answer.
Answer:
It is a rhombus.
Step-by-step explanation:
We have the four equations:
3x - y = -4
3y - x = 4
3y = x + 12
y = 3*x - 4
First, we need to write all of them in slope-intercept form, so they are easier to read.
We get:
y = 3*x+ 4
y = (1/3)*x + 4/3
y = (1/3)*x + 12/3
y = 3*x - 4
First, we can see that:
y = 3*x+ 4 and y = 3*x - 4
are parallel lines, because they have the same slope.
y = (1/3)*x + 4/3 and y = (1/3)*x + 12/3 also are parallel lines, because they have the same slope.
Then this is a parallelogram.
Now, here we have two slopes, 3 and 1/3.
Remember that for a line y = a*x + b
A perpendicular line would be written as:
y = -(1/a)*x + c
From this we can see that there are no perpendicular lines in our set of lines.
Then this can not be a square nor a rectangle.
It can not be a trapezoid, because we would need 3 different slopes to make a trapezoid, and here we have only two.
Then this can only be a rhombus.
Below you can see the graph of the four lines to see which quadrilateral they form.

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

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.
