Answer:
X = -12
Step-by-step explanation:
-10X + 1 +7X = 37
-10X + 7X + 1 = 37 {Add the like terms}
-3X + 1 = 37 {Subtract 1 form both sides}
-3X + 1 -1 = 37 -1
-3X = 36 {Divide both sides by (-3)}

Answer:
25) x = 18 26) x = 50
Step-by-step explanation:
25) 108 + 4x = 180
108 + 4x = 180
-108 -108
4x = 72
x = 18
26)
101 + (x + 29) = 180
101 + 29 + x = 180
130 + x = 180

Answer:
x is about 10.39, y is about 20.78
Step-by-step explanation:
15)
[tex]\tan 30=\dfrac{x}{18}\\x=18 \cdot \tan 30\approx 10.39\\\cos 30 =\dfrac{18}{y}\\y=\dfrac{18}{\cos 30}\approx 20.78[/tex]
Answer:
x=6√3
y=12√3
Step-by-step explanation:
This is a 30 60 90 triangle.
The side opposite from the angle 60 is x√3, which makes 18=x√3, which eventually solves to x=6√3
The side opposite from the 90 degree angle is 2x, so multiply 6√3 by 2, which is 12√3, making y equal 12√3

Determine if b = -3 is a solution to 4b - 6 = -18. Be sure to show all of your work.
Given b equals -3, determine if it is a solution to 4b - 6 = - 18.
So, we have our given which is b = -3, and we are asked to determine if it a solution to the above equation.
To do this, we can plug -3 in for b and see if it works out.
Work:
Plug in -3 for b.
4(-3) - 6 = - 18
-12 - 6 = -18
-12 - 6 = - 18
Thus, b = -3 is a viable solution for the equation of 4b - 6 = -18.

First we, Subtract the 16 from 2x ( which we can't do) so we change the equation to 16 - 2x = 4y
Second we, solve for x. x = −2y + 8, We divide both sides by 2,
-2y/-2= y ( The two -2s cancle each other ) 8/2= 4
x = 4
Next we, solve for y. y = 4 −x/2y, we multiply both sides by 2y,
4 * 2y = 8y ( LOL ) -x/2y * 2y = -x
NOW WE have 8y - x
IDK anything beyond this I'm SORRY T.T
But for the coordinates x is 4

What is Algebraic expression?An algebraic expression (or) a variable expression is a combination of terms by the operations such as addition, subtraction, multiplication, division, etc.
Let's analyze each statement separately:
- Four less than an unknown value --> this means that we have to subtract 4 to an unknown value. Calling the unknown value, it means we have to write y-4
- Quotient of a variable and four --> this means we have to divide a variable by 4. Calling the unknown variable, it means we have to write
z/4
- Some number to the power of four --> this means that we have to write the power of a number, in the form , where m in this case is equal to 4. Calling the unknown number, it means we have to write a⁴
- Four times an unknown value --> this means that we have to multiply an unknown value by 4. Calling our unknown values, we have to write 4x
- Four more than some number --> this means we have to add 4 to an unknown number. Calling the unknown number, it means we have to write b + 4

What is the percent of change in the cost of a DVD set that originally sold for$69.99 and is now on sale for $44.99? Round your answer to the nearest whole number.
Answer: 36%; yes, the % change is equal to the percent discount
Step-by-step explanation:
Initial price = $69.99
Final price = $44.99
change in price = |(final - initial)|
change in price = |(44.99 - 69.99)|
change in price = $25
25/69.99 = x/100
100(25/69.99) = x
100(0.357) = x
35.7% = x
x = 36%

Meera has been visiting banks all day trying to find the best compound interest rate for her savings account. The banks have decided that instead of telling her their rate, they are going to give her the equation that will calculate her current balance after t years. Below are the equations each bank gave to Meera, where f(t) is the balance after t years and P is the principal amount to be placed in the savings account. Select the equation of the bank that has the greatest compound interest rate. Select one:
A. f(t) = P(1.07)t
B. f(t)= P(1.03)2t
C. f(t) = P(1.02)4t
D. f(t) = P(0.90)t
Answer: C.
f(t) = P(1.02)4t
Step-by-step explanation:
f(t) = P(1.02)4t will have the greatest compound interest because the interest is on quarterly bases with an increment of 1.02 and the rate of 8%
Note : 8/100 × 1/4 = 0.02
There is no increment in D and A is yearly based. Option C is for 6 month.

Step-by-step explanation:

The sum of the first six terms of the following sequence is ∑(from i=1 to 6) (-10 - 3(i-1)), the correct option is A.
What is the sum of terms of a geometric sequence?Lets suppose its initial term is f=a , multiplication factor is r
and let it has total n terms, then, its sum of a geometric sequence is given as:
[tex]S_n = \dfrac{a(r^n-1)}{r-1}[/tex]
(sum till nth term)
We are given that;
The sequence; −10, −13, −16, …
Now,
The given sequence is an arithmetic sequence with first term (a1) = -10 and common difference (d) = -3.
Using this formula, we can find the first six terms of the sequence as follows:
a1 = -10
a2 = -10 + (-3) = -13
a3 = -10 + 2(-3) = -16
a4 = -10 + 3(-3) = -19
a5 = -10 + 4(-3) = -22
a6 = -10 + 5(-3) = -25
We can represent the sum of the first six terms using sigma notation as:
∑(from i=1 to 6) ai = (-10) + (-13) + (-16) + (-19) + (-22) + (-25) = -105
The sum of the first six terms of the given sequence is -105.
Using sigma notation, we can write this as:
∑(from i=1 to 6) (-10 - 3(i-1)) = -105
Therefore, by the geometric sequence the answer will be ∑(from i=1 to 6) (-10 - 3(i-1)).
