Twice the difference between a number and 4 is twenty. Find the number.
А. 8
B. 9
C. 12
D. 14
Please help!!!
Answer:
D 14
Step-by-step explanation:
Let x be the number
2(x-4) = 20
Divide each side by 2
2/2(x-4) = 20/2
x-4 = 10
Add 4 to each side
x-4+4 = 10+4
x = 14
Answer:
The number is 14
Step-by-step explanation:
Let's call this unknown number of x:
2×(x – 4) = 20
2x – 8 = 20
2x = 20 + 8
2x = 28
x = 28/2
x = 14
The width of a rectangle is 4 feet more than the length. If the length is doubled and the width is decreased by 2 feet, a new rectangle is formed whose perimeter is 68 feet. Find the dimensions of the original rectangle.
Answer:
Step-by-step explanation:
We'll work through this by setting up a table, as follows:
original new
width
length
It tells us the width of a rectangle is 4 feet more than the length. If we don't know the length, we'll call it L; that means that the width is L + 4, because the width is the length plus 4 more feet. Put that into column 1:
original new
width L + 4
length L
The next sentence tells us how the original rectangle is being manipulated to create a new rectangle, so that information goes into the column named "new". The original length is doubled:
original new
width L + 4
length L 2L
and the original width is decreased by 2:
original new
width L + 4 L + 4 - 2 (which simplifies to L + 2)
length L 2L
The perimeter of the new rectangle is 68. The formula for the perimeter is
P = 2L + 2w, so filling in our info along with the given perimeter:
68 = 2(L + 2) + 2(2L) and
68 = 2L + 4 + 4L and
68 = 6L + 4 and
64 = 6L so
L = [tex]\frac{32}{3}[/tex] and the width then is
w = [tex]\frac{32}{3}+4[/tex] so
w = [tex]\frac{44}{3}[/tex]

15. Determine the y-intercept for the following equation
4x + 2y = -12
Answer:
Step-by-step explanation:
Subtract 4x from both sides
4x-4x + 2y = -4x - 12
2y = - 4x - 12
Divide by 2
2y/2 = -4x/2 - 12/2
y = -2x - 6
The y intercept happens when x = 0
y intercept is - 6
or 0,-6
Answer:
y intercept = -6
x intercept = -3

<RQT is a straight angle. What are m<RQS and m<TQS? (also I know it's 19x+9. I need the numbers like 180 or something) it's degrees.
Answer:
<RQS=103 degrees
<SQT=77
Step-by-step explanation:
19x + 9 = 180 subtract 9 from both sides
19x = 171 divide both sides by 19
x = 9 replace 9 for x in your original
11 x 9 + 4 = 103
8 x 9 + 5 = 77
Answer:
RQS=103°,SQT=77°

WILL MARK BRAINLIEST !! find the coordinates F after a dilation about the origin of 2.5 write your answer in AB form
Explanation:
Point F is located at (2,0)
Multiply each of those coordinates by the scale factor 2.5
2.5*2 = 52.5*0 = 0This means point F(2,0) moves to F ' (5,0) after applying the dilation, where the dilation is centered at the origin.
Write the area A of an equilateral triangle as a function of the length s of its sides.
STEP 1: Find the base of the equilateral triangle in terms of s.
STEP 2: The height of an equilateral triangle can be found via the Pythagorean theorem. Use this information to find h in terms of s.
Write the area A of an equilateral triangle as a function of the length s of its sides. Draw the triangle; label each side "2s". Draw the altitute; it will bisect the base into s and s. ... Therefore, the area is equal to the measure of the bisected side times the measure of the altitude, quantity divided by 2.
HOPE SO IT HELPS YOU
Answer:
Step-by-step explanation:
Part A
Each side including the base is s.
Part B
Use 1/2 the base to find the height. The height meets the base at 90 degrees which gives you the right to use c^2 = b^2 + a^2
The hypotenuse is s
The base is 1/2s
h^2 = s^2 - (1/2s)^2
h^2 = s^2 - 1/4 s^2
h^2 = 3s^2/4
h = sqrt(3)/2 *s
Area = 1/2 * s * sqrt(3)/2 s
Area = 1/4 * s^2 * sqrt(3)

What is the volume of this figure?
Answer:
88 ft^3
Step-by-step explanation:
First find the volume of the rectangular prism on the left
V = l*w*h = 2*(4)*8 = 2*4*8= 64 ft^3
Then find the volume of the rectangular prism on the bottom
The base is not 5 but 5-2 since we used 2 on the left side
V = l*w*h = (5-2) *4*2 = 3*4*2 = 24 ft^3
Add them together
64+24=88

whats the volume the triangular prism?
Answer:
V = 1000 cm³
Step-by-step explanation:
The volume (V) of the triangular prism is calculated as
V = Bh ( where B is the area of the triangular end and h is the height )
B = [tex]\frac{1}{2}[/tex] bh = [tex]\frac{1}{2}[/tex] × 10 × 8 = 5 × 8 = 40 cm² , then
V = 40 × 25 = 1000 cm³
