Answer:
so its 50+.25(x) = y or 140. x is amount of minutes y is total
Answer:
140
Step-by-step explanation:
Can anyone help??? due in 10 mins please.
Step-by-step explanation:
(6x+4)+(4x+26)+110°=180°{straight angle}
10x+140=180°
10x=180-140
x=40/4
x=10
(6x+4)=(6×10+4)=(60+4)=64°
(4x+26)=(4×10+26)=40+26=66°
hope it helps.
Answer:
6x+4+4x+26+110=180 straight line
10x=180-140
x=40/10=4
<A=4x+26=4×4+26=42
What is an equation of the line that passes through the point ( − 1 , − 3 ) and is perpendicular to the line x − 2 y = 14?
Answer:
y = -2 -5
Step-by-step explanation:
x - 2y = 14
-2y = -x + 14
y = 1/2x - 7
-3 = -2 (-1) + b
-3 = 2 + b
-5 = b
y = -2 -5
What is the solution to the system of equations? y = x + 3 3x - 4y = -7
Answer:
x=-5 & y=-2
Step-by-step explanation:
Step 1: Solve y=x+3 for y:
y=x+3
Step 2: Substitute x+3 for y in 3x-4y =-7:
3x-4y=-7
3x-4(x+3)=-7
-x-12=-7 (Simplify both sides of the equation)
-x-12+12=-7+12 (Add 12 to both sides)
-x=5
-x/1=-5/-1 (Divide both sides by -1)
Step 3: Substitute -5 for x in y=x+3:
y=x+3
y=-5+3
y=-2 (Simplify both sides of the equation)
x=-5 and y=-2

Step-by-step explanation:
[tex]\because P(A) + P(A^c) = 1 \\ \\ \therefore \: P(A^c) = 1 - P(A) \\ \\ \therefore \: P(A^c) = 1 - 0.62 \\ \\ \therefore \: P(A^c) =0.38[/tex]
The value of x in the expression
2x/3 - 7 = 5 is
Answer:
The answer is X = 18
Step-by-step explanation:
2x/3 - 7 = 5
Multiply both sides if the equation by 3 : 2x - 21 = 15
Move the constant to the right hand side and change its sign : 2x = 15 + 21
Calculate 2x = 15 + 21
2x = 36
Divide both sides of the eqaution by 2 : 2x = 36
x = 18
Answer X = 18
help please, i don’t understand

one angle of a triangle measures 35°. A second angle measures (3x)°, and the third angle measures 2x - 20)°. what is the value of x?
Answer:
x = 33
Step-by-step explanation:
Sum of the angles in a triangle is 180 so,
35 + 3x + 2x - 20 = 180
35 + 5x - 20 = 180
15 + 5x = 180
5x = 180 - 15
x = 165/5
x = 33
Solve for the variable
Answer:
v= 25
Step-by-step explanation:
Try to isolate the variable by getting rid of the 5. Multiply both sides of the equation by 5 to cancel out the 5 on the left side. You are left with 7v= 35(5). Simplified it is 7v= 175. Then to get the v alone, you need to divide both sides by 7 to cancel out the 7 on the left side. You are left with v= 175/7.
This is v= 25

The difference between four times a number x and 5 is 24.
Answer:
4x - 5 = 24
x= 7.25
Step-by-step explanation:
4x - 5 = 24
4x= 24 + 5
x = 29 / 4 = 7.25
I hope im right!!
this is wrong bc i need a problem not only one number what is the problem for "When I triple my number and add four, I get ten. What is my number?" this
Answer: 2
Step-by-step explanation:
Let's substitute the number as x in the equation.
Triple means you multiply it by 3.
Then you add four, and get 10.
We can write that like this:
3x + 4 = 10
Then subtract 4 from both sides:
3x = 6
And then divide both sides by 3:
x = 2
So the number is 2.

Hannah and Jenny are selling pies for a school fundraiser. Customers can buy cherry pies and
blackberry pies. Castel sold 13 cherry pies and 1 blackberry pie for a total of $97. Jasmine sold
6 cherry pies and 3 blackberry pies for a total of $93. What is the cost each of one cherry pie and
one blackberry pie?
Answer:
6 for cherry
19 for blackberry
Step-by-step explanation:
Cherry = x
Blackberry = y
Make system of equations:
Castel:
13x + y = 97
Jasmine:
6x + 3y = 93
Substitution w/ Castel's equation:
y = 97 - 13x
Put into Jasmine's equation
6x + 3(97 - 13x) = 93
6x + 291 - 39x = 93
291 - 33x = 93
-33x = -198
x = 6 $ per Cherry Pie
Plug x = 6 into any equation (choose Castel's):
13(6) + y = 97
y + 78 = 97
y = 19 $ per Blackberry Pie

If f(x)=x^3-12x^2+35x-24f(x)=x 3 −12x 2 +35x−24 and f(8)=0f(8)=0, then find all of the zeros of f(x)f(x) algebraically.
Answer:
The zeros of f(x) are: (x - 1), (x - 3) and (x - 8)
Step-by-step explanation:
Given
[tex]f(x)=x^3-12x^2+35x-24[/tex]
[tex]f(8) = 0[/tex]
Required
Find all zeros of the f(x)
If [tex]f(8) = 0[/tex] then:
[tex]x = 8[/tex]
And [tex]x - 8[/tex] is a factor
Divide f(x) by x - 8
[tex]\frac{f(x)}{x - 8} = \frac{x^3-12x^2+35x-24}{x - 8}[/tex]
Expand the numerator
[tex]\frac{f(x)}{x - 8} = \frac{x^3 - 4x^2 -8x^2 + 3x + 32x - 24}{x - 8}[/tex]
Rewrite as:
[tex]\frac{f(x)}{x - 8} = \frac{x^3 - 4x^2 + 3x - 8x^2 +32x - 24}{x - 8}[/tex]
Factorize
[tex]\frac{f(x)}{x - 8} = \frac{(x^2 - 4x + 3)(x - 8)}{x - 8}[/tex]
Expand
[tex]\frac{f(x)}{x - 8} = \frac{(x^2 -x - 3x + 3)(x - 8)}{x - 8}[/tex]
Factorize
[tex]\frac{f(x)}{x - 8} = \frac{(x - 1)(x - 3)(x - 8)}{x - 8}[/tex]
[tex]\frac{f(x)}{x - 8} = (x - 1)(x - 3)[/tex]
Multiply both sides by x - 8
[tex]f(x) = (x - 1)(x - 3)(x - 8)[/tex]
Hence, the zeros of f(x) are: (x - 1), (x - 3) and (x - 8)
If the perimeter of a rectangle garden with a width of 15 is 125, what is the perimeter of the daily record it if the scale factor is 60%
Answer:
(here i assume that the daily record is another rectangle)
For a rectangle with width W and length L, the perimeter is:
P = 2*W + 2*L
in this case we know that:
P = 125
W = 15
Replacing these in the perimeter equation we get:
125 = 2*15 + 2*L
125 = 30 + 2*L
125 - 30 = 2*L
95 = 2*L
95/2 = L = 47.5
Now we know that the daily record has a scale factor of 60%.
This means that each measure of this rectangle is (60%/100%) times the equivalent measure of the rectangle garden.
Then if the width of the daily record is W' and the length of the daily record is L'
This means that:
L' = (60%/100%)*L = 0.6*L = 0.6*47.5
W' = (60%/100%)*W = 0.6*W = 0.6*15
Then the perimeter is:
P' = 2*0.6*47.5 + 2*0.6*15 = 75
(notice that is exactly the same than multiplying the original perimeter by (60%/100%) = 0.6)

For the graphed function f(x) = (4)x - 1 + 2, calculate the average rate of change from x = 2 to x = 4.
Answer:
[tex]Average = 30[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 4^{x - 1} + 2[/tex]
Required
Average [tex]rate\ of\ change[/tex] from 2 to 4
This is calculated using:
[tex]Average = \frac{f(b) - f(a)}{b - a}[/tex]
Where
[tex]a= 2[/tex] and [tex]b = 4[/tex]
So:
[tex]Average = \frac{f(4) -f(2)}{4 - 2}[/tex]
[tex]Average = \frac{f(4) -f(2)}{2}[/tex]
Calculate f(2) and f(4)
[tex]f(x) = 4^{x - 1} + 2[/tex]
[tex]f(2) = 4^{2-1} + 2[/tex]
[tex]f(2) = 4 + 2[/tex]
[tex]f(2) = 6[/tex]
[tex]f(4) = 4^{4-1} + 2[/tex]
[tex]f(4) = 4^3 + 2[/tex]
[tex]f(4) = 66[/tex]
So:
[tex]Average = \frac{f(4) -f(2)}{2}[/tex]
[tex]Average = \frac{66 - 6}{2}[/tex]
[tex]Average = \frac{60}{2}[/tex]
[tex]Average = 30[/tex]
Write and solve an equation to find the value of x and a missing angle in the triangle below.
Answer:

Alberto pagó el año pasado 350 euros por un servicio de teléfono móvil. Si este año ha pagado 378 euros, ¿qué tanto por ciento ha aumentado en el gasto de teléfono móvil?
Answer:
the percentage increase is 5.3%
Step-by-step explanation:
The computation of the percentage increase is shown below:
= (Current year - last year) ÷ (last year)
= (378 euros - 359 euros) ÷ (359 euros)
= 19 euros ÷ 359 euros
= 5.3%
hence, the percentage increase is 5.3%
