Answer:
20 boys in class
Step-by-step explanation:
easy
x+(x+5)=35
30=2x
x=15
Answer:
let X be number of boys & y be number of girls in the class
x +y = 35 .....eq 1
x = y +5
y = x -5.......... eq 2
substitute eq 2 in eq 1
x + x -5 =35
2x = 40
x = 20
Which ordered pair would form a proportional relationship with the point graphed below?
On a coordinate plane, a line goes through points (0, 0), (10, 40) and (negative 10, negative 40).
(40, 10)
(–5, –10)
(5, 20)
(–10, –20)
(5, 20) will form a proportional relationship with the point.
Given
A line passes through points (0,0) , (10,40) and (-10, -40)
slope of line is ( 40/10=4 ) and equation of line is ( y=4x )
(40, 10)
x=40 , y=160 Not proportional
(-5, -10)

The table represents a linear equation.
A two column table with 5 rows. The first column, x, has the entries, negative 10, negative 5, 10, 15. The second column, y, has the entries, 8, 7. 4, 3.
Which equation shows how (–10, 8) can be used to write the equation of this line in point-slope form?
y – 8 = –0.15(x – 10)
y + 8 = –0.15(x – 10)
y – 8 = –0.2(x + 10)
y + 8 = –0.2(x – 10)
Answer:
y – 8 = –0.2(x + 10)

For 6z=126, Chris wrote that z=756. Explain what Mike’s mistake was. Then tell the correct answer.
Step-by-step explanation:
6z=126
z = 126 ÷ 6 = 21
Chris's
z = 756
6z= 126
z = 126 × 6 = 756
correct answer = 21
the number 6 is being multiplied with z.So if the number 6 is going to the right side it will divide the number on the right side.
but for chris he multiplied the number on the right side with 6.So that is the mistake.
Thea does not remember in what order she added the ingredients but the last thing she added was 6- 1/4tsp. (6-quarter teaspoons). Select the only option(s) from the checklist below that could have been the last ingredient. * Cinnamon Baking Soda Pure Vanilla Extract Salt Cream of Tartar
Answer:
CinnamonStep-by-step explanation:
From the given ingredient the recipe is meant for cinnamon-sugar cookies
Given the list
(Cinnamon, Baking Soda, Pure Vanilla Extract, Salt ,Cream of Tartar)
With me here is a typical recipe for the baking of cinnamon-sugar cookies
1 cup C&H® Golden Brown Sugar
½ cup C&H® Granulated Sugar
½ cup (1 stick) Unsalted butter, softened
1 teaspoon Pure vanilla extract
2 large eggs
2 ½ cups All-purpose flour
1 teaspoon Cream of tartar
½ teaspoon Baking soda
¼ teaspoon salt
2 tablespoons Granulated Sugar
2 teaspoons ground cinnamon
Now 6- 1/4tsp. corresponds to 6(0.25)=1.5tsp
1.5tsp is a close approximation of 2 teaspoons Ground cinnamon in our typical recipe, hence we could predict that Thea added Cinnamon last
A game show contestant earns y dollars for completing a puzzle in x minutes. This situation is represented by the equation
y = -250x + 5000. How long did a contestant who earned $500 take to complete the puzzle?
Justify your answer
Answer:
it took them 18 minutes to earn $500
Step-by-step explanation:
Step 1: Flip the equation.
−250x+5000=500
Step 2: Subtract 5000 from both sides.
−250x+5000−5000=500−5000
−250x=−4500
Step 3: Divide both sides by -250.
−250x
−250

Point A ( 5, 3) is reflected across the x-axis what is the coordinate of the image.
Answer:
(5, -3)
Step-by-step explanation:
when you reflect across x axis the y changes symbols.
The Point A(5, 3) is reflected across the x-axis, then the coordinate of the image is (5, -3).
What is a reflection?A reflection is a type of transformation that involves flipping a shape, known as the preimage, over a line, known as the line of reflection, to produce a new shape (called the image). You can picture what would happen if you flipped the form over the line in order to graph a reflection.
Given:
The point A(5, 3) is reflected across the x-axis.
The reflection across the x-axis:
The rule for a reflection over the x-axis is,
(x, y) → (x, −y).
So, the image point,
(5, 3) → (5, −3)
Therefore, the image point is (5, −3).

how do you illustrate quadratic equation in one varible?
Answer:
A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared. The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable. One absolute rule is that the first constant "a" cannot be a zero.
