3y = 5
6 = 2x + 2
x = 2, y = 5/3
2x - 2 = 2 ←
Answer:
y = - 4
Step-by-step explanation:
3y = 2x - 6 ................. (1)
4x + 3y = - 24 ........... (2)
(1) ----> (2)
4x + ( 2x - 6 ) = - 24
6x - 6 = - 24
x - 1 = - 4
x = - 3
3y = 2 ( - 3 ) - 6

Triangle ABC is a right triangle. Angle A is the right angle, m∠B=(10x−8)∘, and m∠C=(4x+28)∘. What is m∠C? Enter your answer in the box.
Answer:
C = 48
Step-by-step explanation:
All angles together will equal 180. 1 Angle is a right angle at 90. That leaves 90 for the remaining 2 angels.
set your formula as 10x-8 + 4x+28 = 90 and solve for x
x = 5
now substitute 5 in place of x
c= 4*5 + 28

Nathan mixes green paint and yellow paint in the ratio 3:5.
He makes 16 litres of paint.
How much more yellow paint does he need to add to the mixture so that
the ratio of green paint to yellow paint becomes 1:6?
26 liters of yellow paint need to be added for the ratio of green paint to yellow paint to be 1:6.
EquationAn equation is an expression that shows the relationship between two or more variables and numbers.
From the question:
Amount of green paint = (3/8) * 16 = 6 liters
For the ratio of green paint to yellow paint to be 1:6, let y represent the number of yellow paint to be added.
6 = (1/7) * (16 + y)
16 + y = 42
y = 26
26 liters of yellow paint need to be added for the ratio of green paint to yellow paint to be 1:6.

a wall is 15 cm long,0.2m wide and 2m high. how many bricks of size 15cm×8cm×5cm each are required to construct the wall?
Answer:
100 bricks are required to construct the wall.
Step-by-step explanation:
All calculations should be done with unit in centimetres.
volume of the wall = length * width * height
= 15 * 20 * 200
= 60000 cm³
one brick volume = length * width * height
= 15 * 8 * 5
= 600 cm³
So to fill the entire wall with x walls: volume of wall / one brick volume
→ 60000 / 600
→ 100 bricks

Which of the following ordered pairs make this equation true?
y = 3x
A. (-3,-1)
B. (3, 1)
C. (6,4)
D. (2,6)
Answer:
D
Step-by-step explanation:
substitute the x- coordinate of each point into the equation and if the value obtained is equal to the y- coordinate then the point makes the equation true.
A (- 3, - 1 )
y = 3(- 3) = - 9 ≠ - 1 ← false
B (3, 1 )
y = 3(3) = 9 ≠ 1 ← false
C (6, 4 )
y = 3(6) = 18 ≠ 4 ← false
D (2, 6 )
y = 3(2) = 6 ← true
True or False?
a. If x is a nontrivial solution of Ax = 0, then every entry in x is nonzero.
b. The equation x= x2u + x3v, with x2 and x3 free (and neither u nor v a multiple of the other), describes a plane through the origin.
c. The equation Ax = b is homogeneous if the zero vector is a solution.
d. The effect of adding p to a vector is to move the vector in a direction parallel to p.
In a situation where x is a nontrivial solution, then every entry in x should not be nonzero. Therefore, it's false.
What is a nontrivial solution?A nontrivial solution simply means a system of equation where the determinant of the coefficient is zero. When x is a nontrivial solution of Ax = 0, then at least one entry should be nonzero.
The equation x= x2u + x3v, with x2 and x3 free (and neither u nor v a multiple of the other), describes a plane through the origin. This is true. Since they're free variables, the space span has dimensions and this spans through the origin.
The equation Ax = b is homogeneous if the zero vector is a solution. Since x = 0 is a solution. Therefore, Ax = b. Hence, b = 0.
The effect of adding p to a vector is to move the vector in a direction parallel to p. It should be noted that adding p to a vector moves it in a direction that's parallel.

10 3/9- 10 2/5 Im to lazy to do it please help me out.
Answer:
[tex] \boxed{ \ - \frac{3}{45} }[/tex]
Step-by-step explanation:
10 3/9 - 10 2/5
we need to convert mixed fractions to improper fractions
[tex]10 \frac{3}{9} = \frac{10 \times 9 + 3}{9} = \frac{93}{9} [/tex]
[tex]10 \frac{2}{5} = \frac{10 \times 5 + 2}{5} = \frac{52}{5} [/tex]
Now, we have 93/9 - 52/5
We need to equate the denominators, before subtracting them.
[tex] \frac{93}{9} - \frac{52}{5} = \frac{93 \times 5}{45} - \frac{52 \times 9}{45} [/tex]
[tex] \frac{465}{45} - \frac{468}{45} [/tex]
[tex] \frac{ - 3}{45} [/tex]
[tex] \boxed{ - \frac{3}{45} }[/tex]
The result of 10 3/9- 10 2/5 is - 3/45

Samuel wants to eat at least 15grams of protein each day. Let x represent the amount of protein he should meat each day to meet his goal. Which inequality represents this situation?
Answer:
[tex]x\geq 15[/tex]
Step-by-step explanation:
Samuel wants at least 15 grams
Let's expand on "at least 15"
It means that Samuel wants no less than 15, but 15 or more
It could be 16, but not 14
To create an inequality, 15 or more can be written as [tex]x\geq 15[/tex] (x is 15 more more)
The answer is [tex]x\geq 15[/tex]

a=12
Step-by-step explanation:
a/40=3/10
10 x 4=40, so
3 x 4=12

What is Linear Equations in Two Variables?Linear equations are equations which are in the form of ax + by + c = 0, where a, b, and c are real numbers and also coefficients of both the variables, x and y, must not be equal to zero.
There are infinitely many solutions for a linear equation in two variables.
System of linear equations in two variables consist of two or more equations which are linear in two variables.
System of equations given here are,
3y = 18x + 6 and y = 2x + 14
We are solving this by substitution method.
Substituting y = 2x + 14 in 3y = 18x + 6, we have,
3 (2x + 14) = 18x + 6
Applying distributive property on the left hand side of the equation,
(3 × 2x) + (3 × 14) = 18x + 6
6x + 42 = 18x + 6
42 - 6 = 18x - 6x
36 = 12x
x = 3
Substituting x = 3 in y = 2x + 14,
y = (2 × 3) + 14
y = 20
Hence, the value of y in the solution to the system of linear equations 3y=18x+6 and y=2x+14 is 20.
