Answer:
40/4=x/2
10×2=x
x=20 is your answer
x = 20
is your answer
Let's solve your equation step-by-step.
40
(40)*(2)=x*(4)
80=4x
Step 2: Flip the equation.
4x=80
Step 3: Divide both sides by 4.

Each quadrilateral below is a parallelogram. Find the missing measures
Answer:
[tex]ST=3[/tex], [tex]VT=10[/tex], [tex]m[/tex]∠[tex]V=48[/tex]°, [tex]m[/tex]∠[tex]T=132[/tex]°
Step-by-step explanation:
In a parallelogram, opposite sides are congruent and therefore have the same length. Thus, [tex]ST=RV=3[/tex] and [tex]VT=RS=10[/tex].
Similarly, opposite angles in a parallelogram are congruent and therefore have the same measure. Thus, [tex]m[/tex]∠[tex]V=m[/tex]∠[tex]S=48[/tex]° and [tex]m[/tex]∠[tex]T=m[/tex]∠[tex]R=132[/tex]°. Hope this helps!

Solve the equation
15 - 4x = 2(3x + 1).
[tex]\huge\boxed{\ x=13/10 } :)[/tex]
My steps:
First thing we do is: Rearrange terms
15−4x=2(3x+1)−4x+15=2(3x+1)Second thing we do is: Distribute
−4x+15=2(3+1)−4x+15=6x+2Third thing we do is : Subtract 15 from both sides of the equation
−4x+15=6x+2−4x+15−15=6x+2−15Then you carry on and find solution:
x=13/10
Hope this help's!
Does the given matrix, A, have an inverse? If it does, what is A-1?

A

The inverse of the function is [tex]\left[\begin{array}{ccc}5&-12\\-2&5\\\end{array}\right][/tex]
Inverse of a matrixFor a 2 by 2 matrix, the inverse is generally expressed as:
[tex]\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right] ^{-1}=\frac{1}{ad-bc}\left[\begin{array}{ccc}d&-b\\-c&a\\\end{array}\right][/tex]
Since the given matrix is a square matrix and 2 by 2, therefore it will have an inverse.
Determine the determinant
|A| = 5(5) - 2(12)
|A| = 25 - 24
|A| = 1
Substitute the values into the formula above
[tex]\left[\begin{array}{ccc}5&12\\2&5\\\end{array}\right] ^{-1}=(1)\left[\begin{array}{ccc}5&-12\\-2&5\\\end{array}\right][/tex]
Hence the inverse of the function is [tex]\left[\begin{array}{ccc}5&-12\\-2&5\\\end{array}\right][/tex]

A dolphin jumps out of the water with an initial velocity of 20 feet per
second (assume its starting height is O feet). Use the vertical motion
model, h = - 16t2 + vt +8, where v is the initial velocity in feet per
second and s is the height in feet, to calculate the amount of time the
dolphin is in the air before it hits the water again. Round your answer
to the nearest tenth if necessary.
Time in air: seconds
Answer:
1.6 Seconds
Step-by-step explanation:
The equation would be h(t)=-16t^2+20t+8 since 20 is the velocity, and once you input that onto a graph the answer of when it hits the ground is 1.569 seconds, so rounded is 1.6 seconds.

Answer:
30 cents per orange
Step-by-step explanation:
$2.40 ÷ 8 = 30 cents
Answer:
30 Cents per orange
Step-by-step explanation:
so 2.40/8 to x/1
it will then be 2.40x1 and 8x.
we divide 2.40 by 8 to get x by itself.
Then x = .3 so 30 cents. <3

The Slope Is 12Step-by-step explanation:
Below are the steps to follow to find the slope of any line.
First you need to pick two points. I chose (2,24) and (4,48). (It does not mater what points you chose.)
Now follow the equation
Slope (m) = ΔY/ΔX
ΔY = 48 – 24 = 24
ΔX = 4 – 2 = 2
24/2 = 12
Then no mater what points you chose, 12 should be your final answer

A. x = 5
B. x = 6
C. x = 7
Answer:
x=6
Step-by-step explanation:
Step 1: Subtract 4x from both sides.
5x−3−4x=4x+3−4x
x−3=3
Step 2: Add 3 to both sides.
x−3+3=3+3
x=6
Answer:
B.
Step-by-step explanation:
5x-3+3=4x+3+3
5x=4x+6
5x-4x=4x+6-4x
x=6
