Yanyiah has m dollars. If Erica has 2 times as many dollars as Yanyiah minus 3 dollars, write an expression for how much money Erica has.
Answer: Erica has 2m-3 dollars
Step-by-step explanation:
Amount of dollars Yanyiah has = m dollars =$m
Erica has 2 times as many dollars as Yanyiah minus 3 dollars, can be expressed as =(2m-3)dollars,
We can therefore say Erica has 2m-3 dollars.
put the following equation of a line into slope-intercept form, simplifying all fractions 16x - 4y = -20
Answer:
y = 4x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
16x - 4y = - 20 ( subtract 16x from both sides )
- 4y = - 16x - 20 ( divide terms by - 4 )
y = 4x + 5 ← in slope- intercept form
The equation of a line into slope-intercept form is [tex]y = 4x + 5[/tex].
What is the slope of line?
The slope of a line gives the measure of its steepness and direction.
The slope of a straight line between two points says [tex](x_1,y_1),(x_2,y_2)[/tex] and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The slope is usually represented by the letter ‘[tex]m[/tex]’.
As we know that, the equation of a line in slope- intercept form is
[tex]y = mx + c[/tex]
where [tex]m[/tex] is the slope and [tex]c[/tex] is the y-intercept.
So,
[tex]16x - 4y = - 20\\\\-4y=-20-16x\\\\-4y=-(16x+20)\\\\4y=16x+20\\\\y=\frac{16x}{4}+\frac{20}{4}\\\\y=4x+5[/tex]
Hence, the equation of a line into slope-intercept form is [tex]y = 4x + 5[/tex].

The given figure has five faces, option D is correct.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
The given figure is a triangular prism
A triangular prism is a three-dimensional geometric shape that has two congruent triangular bases and three rectangular faces connecting them. Since each triangular base has one face, there are two faces that are triangular.
Additionally, there are three rectangular faces that connect the triangular bases.
Therefore, a triangular prism has five faces in total.

Answer:
188.24 (rounded)--- 188.2
Step-by-step explanation:
You want to first find the area of all the the different shapes you have...
you have 2 semicircles A= πr²/2 (because it is /2 you don't really need that because in the end you are going to *2 so just make the equation A= πr²)
you have a rectangle A= b*h
you have a triangle A = b*h/2
Semicircles: A= πr² = (3.14) 4² = (3.14*16) = 50.24
rectangle: A = b*h = 12*8 = 96
Triangle: A = b*h/2 = 12 * 7/2 = 84/2 = 42
then you add them up
50.24 + 96 + 42
= 188.24
Nathaly lost 29 cups of sugar by accidentally spilling it all over the floor after she cleaned it up,she asked her neighbor she could borrow some.the neightbor could only spare 18 3/4 cups of sugar.nathly took that then asked another neighbor if she could borrow some. The neighbor could only
spare 18 3⁄4 cups of sugar. Nathaly took that and asked another neighbor who gave her 6
1⁄2 cups. How much more will Nathaly need to replace the sugar she spilled?
She needs 3 3/4 cups more
Step-by-step explanation:
(I think you accidently put the 18 3/4 part twice) but anyways if you add 3/4 and 1/2 you get 1 and 1/4 that will be important later then you do 18 + 6 = 24 and then add your 1 and 1/4 to get a total of 25 1/4 then you just minus that from 29 and get 3 and 3/4

Start with x ^ 2 - 6x + 8 = 0 and complete the squarewhat is the equivalent equation A) (x + 3) ^ 2 = 1 B) (x + 3) ^ 2 = 9 (x - 3) ^ 2 = 1 D) (x - 3) ^ 2 = 9
Answer:
C. (x - 3)² = 1
Step-by-step explanation:
Given;
x² - 6x + 8 = 0
Using completing the square method, the equation above is solved as follows;
x² - 6x = - 8
Half the coefficient of 'x' (-6), square the result and add it to both sides of the equation;
Half of coefficient of x (-6) = ¹/₂ (-6) = -3
x² + (-3)² = -8 + (-3)²
(x - 3)² = -8 + 9
(x - 3)² = 1
Thus, the correct option is 'C'
C. (x - 3)² = 1

Determine the measure of the area of
a sector of 90° in a circle whose
diameter measures 13 centimeters
Answer:
Area of sector = 132.78 cm² (Approx.)
Step-by-step explanation:
Given:
Angle created by sector = 90°
Diameter of circle = 13 centimeters
Find:
Area of sector
Computation:
Radius of sector = Diameter of circle / 2
Radius of sector = 13 / 2
Radius of sector = 6.5 centimeters
Area of sector = [θ/360]πr²
Area of sector = [90/360][22/7][13]²
Area of sector = [1/4][22/7][169]
Area of sector = [0.25][3.1428][169]
Area of sector = 132.78 cm² (Approx.)

Answer:
50
Step-by-step explanation:
Angle 1 is inside a triangle. Angles in a triangle add up to 180.
Angle 1 = 180 - 90 - 40 = 50.
Angle 2 is on a straight line (180 degrees), shared with angle 1. Therefore, angle 2 is 180 - Angle 1 = 130. Angle 3 and 4 can be calculated the same way Angle 2 was calculated (1=3, 2=4).
Angle 5 is 180 - 90 - Angle 3 which is 180-90-50 which is 40.
Angle 6 is 180 - Angle 5 = 180 - 40 = 140.
Angle 8 is the same as Angle 6
Finally, Angle 7 is 180-90 = 90.

Today only, a table is being sold at a 24% discount. The sale price is 475$ What was the price yesterday?
Answer $625:
Step-by-step explanation:
Since the discount is 24% that means that $475 is 76% of the total
X is the 100% of the price (before sale)
475...............76%
x..........................100%
cross multiplication
76x = 475x100
76x = 47500
Divide both sides by 76
x= 625
