5/8 + 2/8 + 7/8 write sum in simplest form

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

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:

y=14

Step-by-step explanation:

because I solved it and got 14 ......

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.

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.

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

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.

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)

[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

26 liters of yellow paint need to be added for the ratio of green paint to yellow paint to be 1:6.

An 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
