Alexa has $60 already saved and her sister Susan has $120 already saved. Alexa is saving $7 per week and her sister is saving $5 per week. How long will it be before Alexa and her sister have the same amount of money? Write an equation and solve.
Step 1: Define your variable
Step 2: Write an equation.
Step 3: Solve your equation.
Step 4: Check your solution.
Step 5: Write a summary statement explaining your solution in the context of the problem..
Plz help mee
Step 1:
The variable is the number of weeks needed to equalize Alexa and her sisters savings.
Step 2:
7x + 60 = 5x + 120
Step 3:
7x+60=5x+120
Subtract 60 from both sides.
7x+(60-60)=5x+(120-60)
7x=5x+60
Subtract 5x from both sides
7x-5x=5x+60-5x
2x=60
Divide both sides by 2.
2x/2 = 60/2
x=30
Step 4:
7(30) + 60 = 5(30)+ 120
210+60=150+120
270 = 270
Step 5:
To find the unknown amount of weeks, you need to rewrite the equation isolate x on the left-hand side of the equation. I just subtracting/simplified the equation until I could solve it.

What is the slope and y-intercept of y=2x+3 and why?
Find the midpoint of the segment with the following endpoints.
(7, -2) (1, -10)
Answer:
(4, -6)Step-by-step explanation:
The formula of a midpoint of the segment AB:
[tex]M_{AB}\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right)[/tex]
We have A(7, -2) and B(1, -10). Substitute:
[tex]M_{AB}\left(\dfrac{7+1}{2};\ \dfrac{-2+(-10)}{2}\right)\\\\M_{AB}\left(\dfrac{8}{2};\ \dfrac{-12}{2}\right)\\\\M_{AB}(4;\ -6)[/tex]
2. Function C takes time for its input and gives a student's Monday class for its output.
a. Use function notation to represent: A student has English at 10:00.
b. Write a statement to describe the meaning of C(11:15) = chemistry.
Answer:
We know that C(T) is a function where you input the time T, and the output will be the student's Monday class.
a) A student has English at 10:00.
Here we can use T = 10:00 as the input, and the output will be the class, English.
Then this can represent this with:
C(10:00) = English.
b) Write a statement to describe the meaning of C(11:15) = chemistry.
for C(11:15) = Chemistry
The input, the time, is 11:15
The output, the class, is chemistry.
The student has a chemistry class at 11:15

Find the value of y.
Answer:
y = -1
Step-by-step explanation:
It´s an equilateral triangle
then:
2y + 6 = 4
2y = 4 - 6
2y = -2
y = -2/2
y = -1
Check:
2*-1 + 6 = 4
-2 + 6 = 4

Complete the work to solve for y:
What is the value for y?
Answer:
The value of y = 11/2
Step-by-step explanation:
As the work is completed up to the point
[tex]\frac{11}{5}=\frac{2}{5}y[/tex]
Now completing the remaining work
[tex]\frac{11}{5}=\frac{2}{5}y[/tex]
Dividing both sides by 2/5
[tex]\frac{11}{5}\div \frac{2}{5}=\frac{2}{5}y\div \frac{2}{5}[/tex]
[tex]\frac{2}{5}\cdot \frac{5y}{2}=\frac{\frac{11}{5}}{\frac{2}{5}}[/tex] ∵ [tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{\frac{b}{c}}=\frac{a\cdot \:c}{b}[/tex]
[tex]\frac{2y\cdot \:5}{5\cdot \:2}=\frac{\frac{11}{5}}{\frac{2}{5}}[/tex] ∵ [tex]\mathrm{Multiply\:fractions}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}[/tex]
[tex]\frac{y\cdot \:5}{5}=\frac{\frac{11}{5}}{\frac{2}{5}}[/tex] ∵ [tex]\mathrm{Cancel\:the\:common\:factor:}\:2[/tex]
[tex]y=\frac{\frac{11}{5}}{\frac{2}{5}}[/tex] ∵ [tex]\mathrm{Cancel\:the\:common\:factor:}\:5[/tex]
[tex]y=\frac{11\cdot \:5}{5\cdot \:2}[/tex] ∵ [tex]\mathrm{Divide\:fractions}:\quad \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c}[/tex]
[tex]y=\frac{11}{2}[/tex] ∵ [tex]\mathrm{Cancel\:the\:common\:factor:}\:5[/tex]
Therefore, the value of y = 11/2

X varies directly as the cube root of y .x=6when y=8.Find the value of x when y=64.
Answer:
The value of x is 12.
Step-by-step explanation:
Given that x is directly proportional to y so the expression will be x = k (³√y) where k is the constant. First, you have to find the value of k :
[tex]x = k \: (\sqrt[3]{y} )[/tex]
[tex]let \: x = 6,y = 8[/tex]
[tex]6 = k \: (\sqrt[3]{8} )[/tex]
[tex]6 = k(2)[/tex]
[tex]k = 3[/tex]
Next, you have to find the value of x, by substituting y = 64 into the expression :
[tex]x = 3 \: ( \sqrt[3]{y} )[/tex]
[tex]x = 3( \sqrt[3]{64} )[/tex]
[tex]x = 3(4)[/tex]
[tex]x = 12[/tex]

Which statement correctly describes the location of the incenter of a triangle?
Question 15 options:
A)
The incenter is equidistant from all three vertices of the triangle.
B)
The incenter is equidistant from all three sides of the triangle.
C)
The incenter is closest to the shortest side of the triangle.
D)
The incenter is closest to the longest side of the triangle.
9514 1404 393
Answer:
B) The incenter is equidistant from all three sides of the triangle.
Step-by-step explanation:
The incenter is the center of the inscribed circle, which is tangent to all three sides. Hence, the distance from the incenter to each side is the radius of the circle. The incenter is equidistant from the sides of the triangle.
