9x + 4 = 5x - 6
help out
Answer:
X = -5/2
Step-by-step explanation:
Step-by-step explanation:
[tex]9x + 4 = 5x - 6[/tex]
Collect like terms and simplify
[tex]9x - 5x = - 6 - 4 \\ 4x = - 10[/tex]
Divide both sides of the equation by 4
[tex] \frac{4x}{4} = \frac{ - 10}{4} [/tex]
Simplify
[tex]x = - \frac{5}{2} [/tex]
help me please ? i need help with this table
Answer:
The last option
Step-by-step explanation:
You can find the slope by using this equation : y2-y1/x2-x1. We can choose any two y coordinates and any two x coordinates to find this. For instance, you can write this as -3-(-2.25)/0-(-1). Now, we can solve.
-3-(-2.25)/0-(-1)
-3+2.25/0+1
-0.75/1
-0.75
-0.75 in fraction form is -3/4.
I'm not quite sure how to calculate the y-intercept, but we know the slope, and that's all we need for this problem (the slope number is next to the x). This makes our answer the last option. Hope this helps!

1/2x + 8 = 10
1/2(2x - 6) = -6
Please help me
Answer:
1/2(2x-6)= -6
Step-by-step explanation:
Multiply the two sides by the equation 2
2x-6=12
move the constant to the right hand side change sign
2x = -12 + 6
calculate the sum
2x= -6
Divide the 2 sides by 2
x= -3
omar tariq has a credit card that uses the unpaid balance method to compute the finance charge. His monthly periodic rate is 2.4% during his billing cycle he charged a total of of 256.28 and made payments totaling $350. If he has a finance charge of 18.28, find his (a) unpaid balance (b) previous balance and (c) his new balance
Answer:
(a) unpaid balance = $667.95
(b) Previous balance = $761.67
(c) his new balance = $683.98
Step-by-step explanation:
In the question, we are given the following:
Monthly periodic rate = 2.4%, or 0.024
Curren charges = $256.28
Total payment made = $350
Finance charge = $18.28
Therefore, we now proceed as follows:
(a) unpaid balance
This can be calculated as follows:
Unpaid balance = Previous balance + Current charges - Total payment made ................. (1)
Note that from part (b), Previous balance is equal to $761.67.
Substituting this and other values from the question into equation (1), we have:
Unpaid balance = $761.67 + $256.28 - $350 = $667.95
(b) Previous balance
This can be calculated as follows:
Previous balance = Finance charges / Monthly periodic rate = $18.28 / 2.4% = $18.28 / 0.024 = $761.67
(c) his new balance
This can be calculated as follows:
New balance = Unpaid balance * (1 + Monthly periodic rate) = $667.95 * (1 + 2.4%) = $667.95 * (1 + 0.024) = $667.95 * 1.024 = $683.98

A radio station tower was built in two sections. From a point that is 70 feet from the base of the tower, the angle of elevation to the top of the section is 28 degrees, and the angle of elevation to the top of the second section is 40 degrees. What is the height of the top section of the tower to the nearest tenth of a foot?
Answer:
21.5 feet
Step-by-step explanation:
d = Distance of the bottom of the tower to the point of observation
x = Height of the top section of the tower
a = Height of bottom section
b = Total height of tower
[tex]\tan28^{\circ}=\dfrac{a}{d}\\\Rightarrow a=d\tan28^{\circ}\\\Rightarrow a=70\tan28^{\circ}[/tex]
[tex]\tan40^{\circ}=\dfrac{b}{d}\\\Rightarrow b=d\tan40^{\circ}\\\Rightarrow b=70\tan40^{\circ}[/tex]
[tex]x=b-a\\\Rightarrow x=70\tan40^{\circ}-70\tan28^{\circ}\\\Rightarrow x=70(\tan40^{\circ}-\tan28^{\circ})\\\Rightarrow x=21.5\ \text{feet}[/tex]
The height of the top section of the tower is 21.5 feet.
Erin is making lemonade, She needs 12 cups
of white sugar to make 8 cups of lemonade.
She has a 32 cup pitcher to fill. How many
cups of sugar will she need?
Answer:
48 cups of sugar.
Step-by-step explanation:
12 cups of sugar for 8 cups of lemonade then I let 32 cups of lemonade corresponding with x cups of sugar, then 12/8 = x/ 32, then 8x = 32 * 12, then solve for x get 8x = 384, x =48.
Answer:
32÷8= 4 cups of sugar...........

- Select all expressions that are equivalent to -96x + 120.
A. 8(-12x+15)
B. -12(8x-10)
C. -8(12x+15)
Answer:
A and B are equivalent to -96x + 120
Step-by-step explanation:
-96x + 120
A. 8 (-12x + 15)
8 * -12x = -96x
8 * 15 = 120
8 (-12x + 15) = -96x + 120
-96x + 120 = -96x + 120
Equivalent
B. -12 (8x - 10)
-12 * 8x = -96x
-12 * -10 = 120
-12 (8x - 10) = -96x + 120
-96x + 120 = -96x + 120
Equivalent
C. -8 (12x + 15)
-8 * 12x = -96x
-8 * 15 = -120
-8 (12x + 15) = -96x-120
-96x + 120 ≠ -96x - 120
Not Equivalent
find the slope of 12x-3y=6
Answer: 4
Step-by-Step Explanation: When written in slope-intercept form, the equation becomes y = 4x - 2; the basic structure of this formula is y=mx+b, where m is the slope and b is the y-intercept.
Knowing this information, we can also figure out the slope and y-intercept. 4, or m, is the slope of the proposed line.
A middle school took all of its 6th grade students on a field trip to see a ballet at a theater that has 1600 seats. The students filled 77% of the seats in the theater. How many 6th graders went on the trip? Please Help
Answer:
You need to find 84% of 4200 to get the amount of students. First change the percent to a decimal, and multiply 0.84 x 4200.

Remy stands on a dock at the edge of a lake represented by point C. Points A and B represent two buoys anchored in the lake. Remy plans to swim from C to A, then to B, and then back to C. The shortest distance from Remy to the swim route AB¯¯¯¯¯¯¯¯ is 60 meters and is measured from C to D.
Answer:
The total distance Remy will swim is approximately 236 meters
Step-by-step explanation:
From the given diagram, of triangle ΔCAB, we have that the path Remy is to swim are;
1) Length of segment C to A
2) Length of segment A to B
3) Length of segment B to C
The length of the perpendicular at point D on segment AB to C = 60 meters
Therefore, DC = 60 m
By trigonometric ratios, we have;
[tex]tan (\theta) = \dfrac{Opposite \ leg \ length}{Adjacent \ leg \ length}[/tex]
[tex]cos(\theta) = \dfrac{Adjacent\ leg \ length}{Hypotenuse \ length}[/tex]
We are given the values of the trigonometric ratios of the following angles;
tan(27°) = 0.51
tan(43°) = 0.93
cos(27°) = 0.89
cos(43°) = 0.73
∴ tan(43°) = AD/DC = 0.93
Where the lengths of AC, AD, DB, DC and BC
AD = DC × tan(43°)
∴ AD = 60 × 0.93 ≈ 55.8
Similarly, we have;
tan(27°) = DB/DC
∴ DB = DC × tan(27°)
DB = 60 × 0.51 ≈ 30.6
From [tex]cos(\theta) = \dfrac{Adjacent\ leg \ length}{Hypotenuse \ length}[/tex], we have;
cos(43°) = DC/AC
AC = DC/(cos(43°))
∴ AC = 60/0.73 ≈ 82.2
Similarly, we have;
cos(27°) = DC/BC
BC = DC/(cos(27°))
∴ BC = 60/0.89 ≈ 67.4
The total distance Remy will swim = AC + AD + DB + BC
∴ The total distance Remy will swim = 82.2 + 55.8 + 30.6 + 67.4 = 236
The total distance Remy will swim = 236 meters
