Answer:

x=3

Step-by-step explanation:

You can find the solution to the two equations by setting them equal to each other.

-\dfrac{2}{3}x+1=\dfrac{1}{3}x-2

Add 2/3x to both sides:

1=x-2

x=3

Hope this helps!

Evaluate the expression if a = 2, b = −3, c = −4, h = 6, y = 4, and z = −1.
Dima020 [189]

The required values are 11 and 19

Given the expression;

15−||2−3a||

If a = 2

Substitute the given value into the expression

If the moduli expression is positive

15−(2−3a)

= 15 - (2-3(2))

= 15 - (2-6)

= 15 - (-4)

= 15 + 4

= 19

If the moduli expression is negative

= 15 - -(2-3(2))

= 15 - -(2-6)

= 15 - -(-4)

= 15 - +4

= 15 - 4

= 11

Hence the required values are 11 and 19

Solve the right triangle shown in the figure.<br> B = 16.9°, b = 30.5
Aloiza [94]

Answer:

A=73.1

a=100.387

c=√ 11007.799769

Step-by-step explanation:

A=180-90+16.9=73.1

Tan(16.9)=30.5/a

=100.387

a^2+b^2=c^2

100.387^2+ 30.5^2=c^2

c=√ 11007.799769

Lynn is going to cover the floor with tiles.
Vlada [557]

Answer:

Please check explanations

Step-by-step explanation:

Firstly, we calculate the area of the floor

That is the product of the sides

= 300 * 540 = 162,000 cm^2

What is left is to calculate the area of a tile

Since the tile is also rectangular, the area of each tile will be;

60 * 30 = 1,800 cm^2

Since we have both areas, we can now get the number of tiles needed to cover the floor

We can get this by dividing the area of the floor by the area of a tile

This is;

162,000/1,800 = 90

This means that 90 tiles will cover the floor

The cost of a tile

is £4.25

The cost of 90 tiles will be ;

£4.25 * 90 = £382.5

from here, we can see that the £400 is more than £382.5

So we can conclude that she has enough to spend on tiles
