Answer:
$160Step-by-step explanation:
Step one:
For Sadie
initial savings balance= $70
weekly savings = $18
Let S represent the amount of money Sadie has saved
and t the number of weeks after the beginning of the year
The total amount in savings after t weeks is
S=18t+70-------1
For Jack
initial savings balance= $90
weekly savings = $14
Let J represent the amount of money Jack has saved
and t the number of weeks after the beginning of the year
The total amount in savings after t weeks is
J=14t+90---------2
Step two
equation 1 and 2 to find t
18t+70=14t+90
18t-14t=90-70
4t=20
divide both sides by 4
t=20/4
t=5 weeks
so after 5 weeks Sadie and Jack will have the same amount of money
For Sadle t=5
S=18(5)+70-------1
S=90+70
S=$160
For Jack t=5
J=14(5)+90---------2
J=70+90
J=160
The two equations above shows that after 5 weeks their savings will be $160

All angles in a triangle add up to 180°Step-by-step explanation:
Step 1: Set up equation
x° + 104° + 32° = 180°
Step 2: Solve for x
Combine like terms: x + 136 = 180Subtract 136 on both sides: x = 44°Answer:
44°
Step-by-step explanation:
Because Sum of three angles of a triangle equals 180 °
So 180°-(104°+32°)
=180°-72°
=44°

5x-4y=-18 and x-4y=6
Answer:
x = -6 and y = -3
Step-by-step explanation:
x- 4y =6
x =4y +6......(i)
5x -4y =-18
20y +30 - 4y = -18
16y = -48
y = -3
x = -12+6
x = -6
Alan compared the slope of the function y=3x+2 to the slope of the linear function that fits the values in this table. Which choice is true about the slopes of the two functions?
OPTIONS:
*The slope of the graph of the table is 1 more than the slope of the graph of the equation.
*The slope of the graph of the table is 2 more than the slope of the graph of the equation.
*The slope of the graph of the equation is 2 more than the slope of the graph of the table.
*The slope of the graph of the equation is 1 more than the slope of the graph of the table.
Answer:
The slope of the graph of the equation is 1 more than the slope of the graph of the table.
Step-by-step explanation:
The slope in the equation of the function, y = 3x + 2, is identified as 3.
We know this because, the equation for the function was given in the slope-intercept form, y = mx + b, where m represents the slope.
Therefore, the slope of the function is 3.
The slope of the function represented by the table of values can be calculated using any two given pairs on the table.
Using (1, 6) and (3, 10):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_2} = \frac{10 - 6}{3 - 1} = \frac{4}{2} = 2 [/tex]
Slope of the function represented by the table of values is 2.
Therefore, comparing the slope of both functions, we can conclude that:
✅"The slope of the graph of the equation is 1 more than the slope of the graph of the table."

4x-2=6x+12 subtract 4x from both sides
-2=2x+12 subtract 12
-14=2x divide by 2
x= -7
Answer:
x = -7
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
2(2x - 1) = 6(x + 2)
Step 2: Solve for x
Distribute: 4x - 2 = 6x + 12Subtract 4x on both sides: -2 = 2x + 12Subtract 12 on both sides: -14 = 2xDivide 2 on both sides: -7 = xRewrite: x = -7Step 3: Check
Plug in x to verify it's a solution.
Substitute: 2(2(-7) - 1) = 6(-7 + 2)Multiply: 2(-14 - 1) = 6(-7 + 2)Subtract/Add: 2(-15) = 6(-5)Multiply: -30 = -30Here we see that -30 does indeed equal -30.
∴ x = -7 is a solution of the equation.

Ans) triangle with all sides equal is called equilateral, a triangle with two sides equal is called isosceles, and a triangle with all sides a different length is called scalene. A triangle can be simultaneously right and isosceles, in which case it is known as an isosceles right triangle
Step-by-step explanation:
There shall be a picture so that you say its name
Hope it helps
Answer:
answer is C. isosceles
because of the two equal sides so it cant be equilateral and it can be right angle because it doesn't have a perpendicular bisector

a._x2 _ 25
How do you do this
Answer:
x=[tex]\frac{+}[/tex]5 or x=5, x=-5
Step-by-step explanation:
If the question is [tex]x^{2}=25[/tex] then you take the square root of both sides. [tex]\sqrt{x^{2}}=\sqrt{5^{2}}[/tex] because 25=5*5=[tex]5^{2}[/tex].
When you simplify you get x=[tex]\frac{+}[/tex]5
So x=-5, =5.

What is the equation of the vertical line through (-8, 5)
Answer:
The equation of the vertical line passing through the point (-8, 5) will be:
[tex]x=-8[/tex]Step-by-step explanation:
As we have to determine the equations for the horizontal and vertical lines passing through the point (-8, 5).
To determine the equation for the vertical line passing through the point (-8, 5), we must observe that the vertical line will always have the same x-value regardless of y-values.
Therefore, the equation of the vertical line passing through the point (-8, 5) will be:
