Answer:
You showed no model. However, looking at this equation it seems the answer would be x=3.
Step-by-step explanation:
Add 2 to both sides which leaves you with 6=2x and then divide both sides by 2 to get x=3.
What is the solution of (x+8)/(5x+-1)>0?
Answer:
the solution set is (-infinity, -8) ∪ (-8, 1/5)
Step-by-step explanation:
x + 8 changes sign at x = -8.
I'll assume you meant 5x - 1 (as 5x+- is meaningless). 5x - 1 changes sign at x = 1/5.
Subdivide the x-axis using the two x-values found above:
(negative infinity, -8), (-8, 1/5), (1/5, infinity.
Choose a representative value from each interval. I'm choosing x = -10, x = 0 and x = 1.
Now test the given inequality at each of these x-values. Is the result true or false?
x + 8
---------- > 0
5x - 1
For x = -10:
-10 + 8
--------------- > 0 => -2/(-51) => 2/51 This is TRUE
5(-10) - 1
For x = 1:
1 + 8
---------- > 0 => 9/4 This is TRUE
5 - 1
For x = 0:
8
---------- > 0 This is FALSE
- 1
Therefore the solution set is (-infinity, -8) ∪ (-8, 1/5)

Help pls I’m stuck on this question
Answer:
We have 15 Nickels and 10 Dimes.
Step-by-step explanation:
This is a system of equations! [Literally in a class reviewing that rn}
Lets make a chart:
Number of Coins x Value of Coin = Total Value
Dimes | d | 10 | 10d
Nickels | n | 5 | 5n
So, When you have a System of Equations with Money, One equations is about the value of the money, and the other about the number of coins.
The First Equation [Number of Coins]:
D + N = 25
the Second Equation [Value of Money]:
10D + 5N = 175
I will use Elimination to solve this, however, graphing and substitution works too.
ELIMINATION:
Multiply First equation by -5
-5[D + N = 25] = -5D - 5N = -125
Add the Two Equations vertically.
-5D - 5N = -125
10D + 5n = 175
---------------------
5D = 50
Divide both sides by 5.
5D/5 = 50/5
D = 10
Substitute D= 10 In any equation and solve for the other variable.
10 + N = 25
Subtract 10 from both sides.
10 - 10 + N = 25 - 10
N = 15
So, we have 15 Nickels and 10 Dimes.

Find the volume of the cylinder
Answer:
pi 50 x^4
Step-by-step explanation:
The volume of a cylinder is
V = pi r^2 h
The radius is 5x and the height is 2x^2
V = pi (5x)^2 * 2x^2
V = pi ( 25x^2) (2x^2)
= pi 50 x^4
Answer:
[tex]50\pi x^{5}[/tex]

For the following arithmetic sequence, find the value of a and d and hence find the term indicated: - 2 , 2 , 6 , 10 , . . . , t 7. If the first term of an arithmetic sequence is 7 and the 4th term is 28, find the value of d.
Answer:
[tex]t_{7}[/tex] = 22 is the answer to the first question
d = 4 is the answer to the second question
Step-by-step explanation:
use the formula [tex]a_{n} = a + (n - 1)d[/tex]
6 - 2 = 4 = d a = -2 n = 7
[tex]t_{7}[/tex] = -2 + (7 - 1)4
= -2 + 6(4)
= -2 + 24
= 22
use the formula [tex]a_{n} = a + (n - 1)d[/tex]
a = 7
n = 4
[tex]a_{4} = 28[/tex]
28 = 7 + (7 - 1)d
= 4 + 6d
24 = 6d
d = 4

Two girls are standing 100 feet apart they both see a beautiful seagull in the air between them the angles of elevation from the girls to the bird are 20 degrees and 45 degrees respectively how high up is the seagull
Answer:
[tex]26.68\ \text{feet}[/tex]
Step-by-step explanation:
a = 100 feet
[tex]\angle B=20^{\circ}[/tex]
[tex]\angle C=45^{\circ}[/tex]
[tex]\angle A=180-(20+45)=115^{\circ}[/tex]
From sine rule we have
[tex]\dfrac{\sin B}{b}=\dfrac{\sin A}{a}\\\Rightarrow b=\dfrac{\sin B}{\sin A}a\\\Rightarrow b=\dfrac{\sin 20^{\circ}}{\sin 115^{\circ}}\times 100\\\Rightarrow b=37.73\ \text{feet}[/tex]
[tex]\sin C=\dfrac{h}{b}\\\Rightarrow h=b\sin C\\\Rightarrow h=37.73\times \sin 45^{\circ}\\\Rightarrow h=26.68\ \text{feet}[/tex]
The is seagull is [tex]26.68\ \text{feet}[/tex] above the ground.

The volume of this pyramid is 36.67 m3. If the area of its base is 10.0 m2, how high is the pyramid? Round to the nearest whole meter. a) 4 m b) 11 m c) 5m d) 12 m
Answer:
b
Step-by-step explanation:
A pyramid is a three-dimensional object. The base of a pyramid is a polygon. the top and the base of a polygon forms a triangle
The volume of a pyramid = 1/3 × (area of base x height)
volume = 36.67 m3
area = 10.0 m2,
height = ?
36.67 = 1/3 x (10 x h)
multiply both sides of the equation by 3
110.01 = 10h
divide both sides by 10
h = 11.0001 m

How many one-inch cubes will fit in the box?
Answer:
D. 132,651 cubes
Step-by-step explanation:
You're looking for how many cubes fit in the box. Remember cubic means 3 dimensions and squared means 2 dimensions.
Use length x width x height and converting the 4.25 feet to inches...
4.25×12=51
51×51×51=132,651
Meaning 132,651 one inch cubes would fit.
Answer:
132,651 cubes
Step-by-step explanation:
4.25 ft = 51 inches
51 x 51 x51 = 132,651 inches
1 x 1 x 1 = 1 inch cubes
so
132,651 divided by 1 = 132,651.
Pretty please HELP MEEEE A circular flower bed is 19 m in diameter and has a circular sidewalk around it that is 3 m wide. Find the area of the sidewalk in square meters. Use 3.14 for pi.
SA is the area of flowerbed
radius is 9.5 m (diameter, 19, divided by 2)π(r)²3.14(9.5)²3.14(90.25)SA = 283.385 m²LA is the large area of both flowerbed and sidewalk together

Of flowers in a field 43% are yellow . The others are white. A bee randombly lands on a flowerdescribe the complelment of the bee landing on a yellow flower. Determine its probability
Answer:
0.43
Step-by-step explanation:
Yellow flowers are 43%.
White flowers are = (100% - 43% ) = 57%
Consider there are total 100 flowers in the garden , so yellow ones are 43 and white ones are 57
Probability of a bee landing on a yellow flower is 43 out of 100
= 43/ 100
=0.43
