Answer:
Shonda has ( x )dollars in her piggy bank.
Rizzo has ( x-1.50 )
if Shonda has $9 more than x; (x+9),would be equal to
3 times the dollars Rizzo has, or, 3(x-1.50). The two quantities are equal, we can solve for x.
x+9 = 3(x-1.50)
Dustribute the 3
x+9 = 3x - 4.50
Isolate the variable on the left and constants on the right of the equation by subtracting 3x and 9 from both sides.
x+9 = 3x - 4.50
-3x-9 = -3x - 9
-2x = - 13.50
Divide both sides by - 2
Shonda has; x = 6.75
Rizzo has; (6.75 - 1.50) = 5.25
6.75 + 9 = 3(6.75 - 1.50)
15.75 = 3(5.25) or 15.75.
Passes the check.
Shonda has $6.75 in her piggy bank and Rizzo has $5.25.

Micah has three 6-foot-long sandwiches. He needs to cut pieces that are 8 inches long from the sandwiches. What is the greatest number of 8-inch pieces he can cut from the three sandwiches?
Answer:
27 pieces
Step-by-step explanation:
1) first, multiply 6 times 3 (6×3=18)
2) 1 ft = 12 in. so you multiply the 18 by 12 (18×12=216)
3) now you divide the 216 by 8 (216÷8=27)

Answer:
It has infinity solutions.
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The equation 49x + 9 = 49x + 83 has no solutions.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 4 is an equation.
2x + 4x + 5 = 7 is an equation.
We have,
49x + 9 = 49x + 83
Solving for x we get,
49x + 9 = 49x + 83
Subtract 49x on both sides.
9 = 83
This is not true.
This condition is a system of equations where there are no solutions.
Thus,
The equation 49x + 9 = 49x + 83 has no solutions.

Answer:
the length of PQ is equal to the length of P'Q'
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.
Translation is the movement of a point either up, down, right or left. Translation is a type of rigid transformation. Rigid transformation is a transformation in which both the image and pre-image have the same shape and size. types of rigid transformation are rotation, reflection and translation.
Quadrilateral PQRS is translated to the left by 4 units to obtain another quadrilateral P᾿Q᾿R᾿S᾿. Since translation is a rigid transformation, the shape and size of PQRS is the same as that of P'Q'R'S. Hence the length of PQ is equal to the length of P'Q'.
To solve the problem we must know about translation.
What is translation?A translation is a process of moving a graph or point from its initial location to another location without making any changes in its shape or size, we can tell whether the translation is done towards the right, left, up, or down by just looking at the operation that takes place within the parentheses of a function or a completely separate function.
The correct option is B, the length of P'Q' is equal to PQ.
Given to us
A quadrilateral PQRS is translated to the left by 4 units to obtain another quadrilateral P᾿Q᾿R᾿S᾿
As we know translation does not cause any change in the shape and the size of the quadrilateral, therefore,
Area of PQRS = Area of P'Q'R'S'PQ = P'Q'QR = Q'R'RS = R'S'PS = P'S'Hence, the correct option is B, the length of P'Q' is equal to PQ.

What two numbers multiply to -32 and add up to 4
Answer:
-4 and 8
Step-by-step explanation:
-4 x 8 = -32
-4 + 8 = 4
The two numbers that multiply to -32 and add up to 4 are -8 and 4.
To find two numbers that multiply to -32 and add up to 4, we can use a factoring approach or trial and error.
Let's consider two numbers, x and y, such that:
xy = -32 (Equation 1)
x + y = 4 (Equation 2)
We need to find values of x and y that satisfy both Equation 1 and Equation 2 simultaneously.
By trying different pairs of numbers, we can find that -8 and 4 satisfy both equations:
-8 * 4 = -32 (Equation 1)
-8 + 4 = 4 (Equation 2)
Therefore, the two numbers that multiply to -32 and add up to 4 are -8 and 4.

Answer:
y-intercept: -5
Slope: 4
Equation: y = 4x - 5
Step-by-step explanation:
✔️ y-intercept (b):
When x = 0, y = -5. Therefore, the y-intercept (b) = -5. It is the point at which the y-axis cut across by the line. At this point, x is always zero.
✔️Slope using two points (0, -5) and (1, -1):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-1 - (-5)}{1 - 0} = \frac{4}{1} = 4 [/tex]
Slope (m) = 4
✔️Equation in slope-intercept form y = mx + b:
Substitute m = 4, and b = -5 into y = mx + b
y = 4(x) + (-5)
y = 4x - 5
Share 144 in the ratio 7:9
Answer:
The parts are 63 and 81
Step-by-step explanation:
Ratios
We have to split the number 144 into two parts such that they are in the ratio 7:9.
Let's call
x = one of the parts
144 - x = the other part
It must be satisfied:
[tex]\displaystyle \frac{x}{144-x}=\frac{7}{9}[/tex]
Cross-multiplying the denominators:
9x = 7(144 - x)
Operating:
9x = 1008 - 7x
Adding 7x:
16x = 1008
Dividing by 16:
[tex]x = \frac{1008}{16}=63[/tex]
First part: x=63
