in order to find d,we need to remove that 6 on 6d.so in order to remover 6,we divide both 6# and 108 by 6.so 6 divided by 6 we will be left with d = 108 devided by 6
so the answer is d=18

Joanna is reading a storybook. The ratio of the number of pages she read to
the pages that remain to be read is 7:3. If the book contains 500 pages in all,
how many pages did Joanna read and how many pages remain to be read?
Answer:
The amount of pages that remain to be read is 150 pages
Step-by-step explanation:
Okay if we know it's in 7:3 ratio we can easily add them both to get 10, then divide 10 by 500 to get 50. SO we now know that 50 is 1 unit and since the ratio says 3 units is the answer, we multiply 50 by 3 to get 150.

-5x + 26 = -44
Answer:
14
Step-by-step explanation:
-5x+26=-44
-26 -26
-5x=-70
5 5
x=14
Answer:
x=14
Step-by-step explanation:
Let's solve your equation step-by-step.
−5x+26=−44
Step 1: Subtract 26 from both sides.
−5x+26−26=−44−26
−5x=−70
Step 2: Divide both sides by -5.
−5x−5=−70−5x=14

form of the following expression 3⁴.35.36
Answer:
[tex]3^4*3^5*3^6 = 3^{15}[/tex]
Step-by-step explanation:
Given
[tex]3^4*3^5*3^6[/tex]
Required
Simplify
To do this, we apply laws of indices:
[tex]a^m * a^n = a^{m+n}[/tex]
So:
[tex]3^4*3^5*3^6 = 3^{4+5+6}[/tex]
Add the exponents
[tex]3^4*3^5*3^6 = 3^{15}[/tex]

The sum of two numbers is 23. Twice one number increased by 6 is the same as 4 times the other number decreased by 2. What is the largest of the two numbers?
Answer:
One number is 4.2, the other is 18.8
Step-by-step explanation:
1.) x+y=23
(x+6y)x2=4
2.) (x+6y)x2=4 = 2x+12y=4
3.)Use elimination/substitution to solve
2x+12y=4 = x+6y=2 = x=2-6y
2-6y+y=23
4.)Solve for y
2-5y=23 -> -5y=21 -> y=4.2.
5.)Solve for x
x+4.2=23
x=18.8

What is the measure of AC? Thanks!!
Answer:
arc AC = 21 degrees
Step-by-step explanation:
2(3x-1.5) = 3x+9
6x-3 = 3x+9
3x = 12
x = 4
arc AC = 3(4) + 9 = 21

Find x. Round to the nearest tenth.
27
26.2
Answer:
14.0°
Step-by-step explanation:
Reference angle = x
Hypotenuse = 27
Adjacent = 26.2
Apply trigonometric function, CAH:
Cos x = Adj/Hyp
Cos x = 26.2/27
Cos x = 0.97037037
x = Cos^{-1}(0.97037037)
x = 13.9823107°
x = 14.0° (nearest tenth)

Graph the linear equation ax +by = c, where a = 0, b = 1, and c = 1.5.
Step-by-step explanation:
ax +by = c
0(x) + 1(y) = 1.5
Answer:
ax +by = c,
by substituting value
0×x+1×y=1.5
y=1.5
An account with an initial balance of $4000 earns 6.5% interest for 5 years.
What is the ending balance?
Enter your answer in the box.
The ending balance is $5,480.
Given that,
The initial balance is $4,000.The rate of interest is 6.5%.And, the time period is 5 years.Based on the above information, the calculation is as follows:
[tex]= \$4,000 \times (1 + 0.065)^5[/tex]
= $5,480
Therefore, the ending balance is $5,480.

An airplane is flying overhead at a constant elevation of 405 ft. A person is viewing the plane from a position 3040 ft from the base of a radio tower. The airplane is flying horizontally away from the person. If the plane is flying at the rate of 640 ft/s, at what rate is the distance between the person and the plane increasing when the plane passes over the radio tower? At the moment the plane passes over the tower, the distance between the person and plane is changing at a rate of ________ft/s
Answer:
δL/δt = 634,38 ft/s
Step-by-step explanation:
A right triangle is shaped by ( y = distance between aircraft and ground which is constant and equal to 405 f ) a person who is at ground level 3040 f away from the tower distance x = 3040 f and the line between the aircraft and the person. Then we can use Pythagoras theorem and write
L ( distance between aircraft and person )
L² = x² + y² or L² = x² + (405)²
Taken partial derivatives with respect to t we get:
2*L*δL/δt = 2*x*δx/t + 0
Then L*δL/δt = x*δx/dt
At the moment of the aircraft passing over the tower
x = 3040 ft δx/δt = 640 ft/s and L = √ ( 3040)² + (405)²
So L = √9241600 + 164025 L = √9405625 L ≈3066,9 ft
Then:
δL/δt = 3040*640/ 3066,9 units [ ft * ft/s / ft ] ft/s
δL/δt = 634,38 ft/s

Can someone please help? f(x) = |x − 2| − 4 and g(x) = 1/2x − 2 solve algebraically for x.
Answer:
x = 8, x = 0 intercepts: (8,2) (0,-2)
Step-by-step explanation:
|x − 2| is a positive value, x can be x ≥ 2 or x ≤ 2
when x≥2, then
y = x-2-4 =x-6 and y = 1/2x - 2
x-6 = 1/2x-2
1/2x=4
x = 8
When x≤2
y = -(x-2)-4 = -x - 2
y = 1/2x - 2
-x - 2 = 1/2x - 2
x = 0
solve -2(x + 4) + 9 < -11 then graph.
Answer:
-2x-8+9<-11
-2x+1<-11
-2x<-11-1
-2x<-12
divide both sides by -2
