x is a whole number such that 7x – 3 > 18
Write down the smallest value of x.
Answers
7x - 3 > 18
Add 3 to both sides
7x > 21
Divide both sides by 7:
X > 3
Since x has to be greater than 3 the smallest whole number that would work is 4
Answer: 4
Answer:
see below
Step-by-step explanation:
7x – 3 > 18
Add 3 to each side
7x – 3+3 > 18+3
7x> 21
Divide by 7

X=
2x + 20
Answers
Answer: x = 25
Step-by-step explanation:
This appears to be an equilateral triangle. All angles are shown to be the same. This means all 3 sides will have the same length:
3x-5
4x-30
2x+20
are all equal to each other.
3x-5 = 4x-30
x = 25

3x-5 = 70

The width of a rectangle is the length minus 4 units. The area of the rectangle is 12 units. What is the width, in units, of the rectangle?
Answers
Answer:
the width is 3
Step-by-step explanation:
you divide the 4 by 12
Answer:
2 units
Step-by-step explanation:
Area = Length × Width of a rectangle
If Length = L
Width = L-4
So 12 units = L×(L-4)
12 = L^2 -4L
L^2 -4L -12=0
Simplify this equation
L^2 + 2L -6L -12 = 0
L( L+2) - 6(L+2) = 0
(L+2) (L-6) = 0
L+2 =0 Or L-6=0
L=-2 Or L= +6
But L can't take a negative value
therefore L= 6
Now if we substitute and check,
L× (L-4) = 6×2=12 units
width = 6-4 =2 units

y = 32, x = 43
To figure this out, you have to use what you know to find all sorts of measures.
Lets start with the 75 degree angle. We know that the opposite side is a vertical angle, so that is also equal to 75 degrees. Since the angle to the big triangle is a supplementary angle, we know that the sum of 75 degrees and that angle is 180 degrees. Do the math and we get 180 - 75, or 105 degrees. The angles of a triangle always add up to 180, so 105 + 43 + y = 180. Solve for y: [tex]148+y=180=148-148+y=180-148=y=32[/tex]. So y is equal to 32 degrees. Now to find x, we know that the bases of the triangles are parallel, and that there is a line that goes straight from angle y to one of our unknown angles. Because the triangle bases are parallel and the y to unknown line does not change, we can tell that those are the same. So y = unknown angle 1, or 32 = 32. So, we know the measure of one angle. The other unknown angle is vertical to the other angle we found earlier, 105. So, we get 105 + 32 + x = 180. Evaluate: [tex]32+105+x=180=137+x=180=137-137+x=180-137=x=43[/tex]. So x is equal to 43.

3x2 - 12x + 11 = x
Answers
Answer:
(13 + or - (sign) square root(37)) / 6
Step-by-step explanation:
First search up the quadratic formula which is
x = (- b + or - square root(b^2 - 4ac)) / 2a
and to find a, b, and c you need this formula
ax^2 + bx + c = 0 (btw this is the safest solution to finding your answer with a number in-front of a quadratic equation.)
Math:
a = 3, b = -13, c = 11
b = -13, because of the x on the other end of the equation as the equation above "ax^2 + bx + c = 0" you need the zero to proceed to this next step.
Side Note: You only take the number and not the variable, variables are x, y, w, z, or etc.
(- (- 13) + or - square root((-13)^2 - 4(3)(11) ) ) / 2 * 3
13 + or - square root(37) / 6

Step-by-step explanation:
To get an answer in ratio form, we must convert meters into millimeters or we can convert millimeters to meters. Then we can get our answer.
Step 1: Convert.
=> 5 millimeters : 1 meter
=> 5 millimeters : 1000 millimeters
Step 2: Simplify.
=> 5 millimeters : 1000 millimeters
=> 1 millimeter : 200 millimeters
Key Note: Answer in ratio form is always unitless.
=> 1 : 200
So therefore, 1 : 200 is our ratio. Hoped this helped.
Use matrices to rotate the vector v=<-4 , 1> by 270°. Write the resulting vector in component form
Answers
Using rotation rules, it is found that the resulting vector is:
v = <1, 4>
When a vector in component form <x,y> is rotated by 270 degrees, the rule is:
<x, y> -> <y, -x>
That is, x and y are switched, and the signal of x changes.
In this problem, the vector is v <-4, 1>, hence:
<-4, 1> -> <1, -(-4)> -> <1,4>
Hence, <1,4> is the resulting vector.
