Which property will we need to use to solve the equation?

x - 10 = 5

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

Answer:

no solution

Step-by-step explanation:

-2y-3y+8=8-5y-12

-2-3y=-5y

-5y+8=8-5y-12

inverse operation: add 5y to both side

-5y+8=8-5y-12

+5y        +5y

-5y+5y=0, so it cancels out both -5ys

8=8-12

8=-4

there is no value for y to make the equation true, so there is no solution

Answer:

The second one

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

your answer is correct, dw.

Step-by-step explanation:

When Cara works for 1 hour, she earns 7*1 + 4 = 11 dollars. The value of h increments as Cara babysits longer, but she gains the 4 dollar transportation fee regardless of her workhour.

Answer:

length of RT = 4

Step-by-step explanation:

triangle RST has been enlarged by 3 as the length of ST is 3x longer than BC

so the length of RT (12) can be divisible by 3 that gives AC the length of 4cm

Answer:

[tex] \boxed{ \sf{7 \frac{1}{2} }}[/tex]

Step-by-step explanation:

convert to fraction form a/b

25 1/3 - 17 5/6

[tex]25 \frac{1}{3} = \frac{25 \times 3 + 1}{3} = \frac{76}{3} [/tex]

[tex]17 \frac{5}{6} = \frac{17 \times 6 + 5}{6} = \frac{107}{6} [/tex]

Now, we have 76/3 - 107/6

[tex] \frac{76}{3} - \frac{107}{6} [/tex]

[tex] \frac{76 \times 2}{6} - \frac{107}{6} [/tex]

[tex] \frac{152}{6 } - \frac{107}{6} [/tex]

[tex] \frac{45}{6} [/tex]

simplify

[tex] \purple{ \boxed{ \frac{45}{6} = 7 \frac{3}{6} = 7 \frac{1}{2} }}[/tex]

Answer:

y=14

Step-by-step explanation:

The value of y in the solution to the system of equations given is 20.

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.

Answer: That hexagon can be partitioned into six equilateral triangles, each with side of 9 meters. The area of an equilateral triangle is which in this case is which is roughly 35.074 square meters. The area of the hexagon is six times that, which comes to about 210.44417312 square meters.

Step-by-step explanation:

In a situation where x is a nontrivial solution, then every entry in x should not be nonzero. Therefore, it's false.

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.

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

10 x 4=40, so

3 x 4=12

a=12

Answer:

[tex]\boxed{\sf{x=12}}[/tex]

Step-by-step explanation:

Isolate the term of a from one side of the equation.

Solution: Multiplication property of equation.

a/40=3/10

First, multiply by 10 from both sides.

[tex]\sf{\dfrac{a}{40}\cdot \:10=\dfrac{3}{10}\cdot \:10}[/tex]

Solve.

a/4=3

Then, multiply by 4 from both sides.

4a/4=3*4

Solve.

3*4=12

a=12

As a result, the correct answer is a=12.
