Answer: x - 1.5
4x – 97 + 12 – x = -80.5
3 x - 85 = -80.5
3 x - 85 +85 = -80.5 + 85
3x = -80.5 + 85
3x = 4.5
x = 1.5
Step-by-step explanation: hope this helps
Answer:
x=1.5
Step-by-step explanation:
4x-97+12-x=-80.5
Combine like terms
-97+12=-85
4x-x=3x
now you have 3x-85=-80.5
add 85 to both sides and now you have
3x=4.5
Now divide 3 to both sides and you get x=1.5

The lenght of a turtles shell z, in millimeters, is related to the turtles age in years a , as described by the equation below.
s=55a+37
Which statements about the turtle are true?
Select 3
Answer:
B, C , F
Step-by-step explanation:
The age multiplied 55, so the shell grows at rate of 55mm per year
in fact if the age is 2 we have (55 x 2) = 55 + 55
if 3 = (55 x 3) = 55 + 55 + 55
and so on
When the turtle is hatched the shell is 37 mm in lenght.
In fact, if we substitute 0 to a, we have
s = (55 x 0) + 37
s = 37
when the turtle is 1 year old, the shell is 92 mm in length.
in fact if we substitu a with 1, we have
s = (55 x 1) + 37
s = 55 + 37
s = 92

Answer:
I think it C
Step-by-step explanation:
Let's solve your equation step-by-step.
(k−4)2=9
Step 1: Simplify both sides of the equation.
k2−8k+16=9
Step 2: Subtract 9 from both sides.
k2−8k+16−9=9−9
k2−8k+7=0
Step 3: Factor left side of equation.
(k−1)(k−7)=0
Step 4: Set factors equal to 0.
k−1=0 or k−7=0
k=1 or k=7
Answer:
k=1 or k=7
Hope this helps! :)
Square both sides:
K -4 = sqrt(9)
With the answer being a square root rewrite with a postive and negative value:
K-4 = sqrt(9)
And
K-4 = -sqrt(9)
Simplify each:
K-4 = 3
And
K-4 = -3
Solving for k in each one you get answer

The volume of the given hemisphere is 59131.7 inches³.
What is a hemisphere?
Hemisphere is the exact one-half of the sphere.
given, diameter of the hemisphere is = d = 60.9 inches
Therefore, radius = d/2 = 60.9/2 inches = 30.45 inches.
Hence, the volume = (2/3) × π × r³ = (2/3) × π × (30.45)³ inches³ = 59131.7 inches³.

A rectangular goat pen has an area of 32 square meters and a perimeter of 24 meters. What are the dimensions of the pen?
Answer:
Breadth is 4 m and length is 8m
Step-by-step explanation:
Area of the rectangle = Length * breadth
Area of the rectangular goat pen= 32 square meters
Perimeter of the rectangular goat pen = 24 meters
Perimeter of the rectangle = 2(length + breadth)
24= 2(l+b)
12= length + breadth
12- breadth = length ----------- equation A
Area = l*b
32= l*b
32= (12- b) *b
32= 12b- b²
b²-12b+32= 0------------------- equation B
Solving the quadratic equation by factorization
b²- 8b- 4b+32= 0
b(b-8) -4(b-8)= 0
(b-8) = 0
(b-4)= 0
b= 8 or b=4
As breadth is usually smaller than length then putting b= 4 in equation A
gives
12- breadth = length
12-4= length
length = 8
Hence breadth is 4 m and length is 8m
The radius of a circle is 4 feet. What is the length of a 90° arc? HELP ME PLEASE
Answer:
6.3feet
Step-by-step explanation:
Given data
Radius= 4feet
The expression for the circumference of a circle is
C= 2πr
Substitute
C=2*3.142*4
C=25.136 feet
Also, a 90° arc is 1/4 of the circumference of a circle
Hence the length of the 90° arc is
=25.136/4
=6.284 feet
