Answer:

x = 6

Step-by-step explanation:

To solve, move all the x’s to one side and all the numbers. Remember when moving numbers to the other side of an equation, the sign changes from either a positive to a negative or vise versa.

9 + 3 = 4/3x + 2/3x

Next, add the like terms.

9+3=12

When adding fractions, add the numerator (top number), but first change denominator (bottom number) if not the same. Here, we don’t need to.

4/3x+2/3x=6/3x

So,

12 = 6/3x

Then, we have to divide each side by 6/3 to make the x alone.

12/6/3 = 6/3x/6/3

To divide with fractions, multiply the reciprocal (opposite number on number line):

12/1·3/6 = x

36/6 = x

6 = x

Answer:

The measure of angle EYH is $25\°$

Step-by-step explanation:

step 1

Find the measure of arc EH

we know that

$arc\ EV+arc\ VL+arc\ HL+arc\ EH=360\°$ ----> by complete circle

substitute the given values

$130\°+110\°+40\°+arc\ EH=360\°$

$280\°+arc\ EH=360\°$

$arc\ EH=360\°-280\°=80\°$

step 2

Find the measure of angle EYH

we know that

The measurement of the outer angle is the semi-difference of the arcs which comprises

$m$

substitute the values

$m$

What is the surface are of a rectangular prism of the length is 18cm the width 6cm and the height 3cm

Harlamova29_29 [7]

The surface area of rectangular prism is 360 square inches

Solution:

Given that rectangular prism of the length is 18 cm the width 6 cm and the height 3 cm

To find: Surface area of rectangular prism

The Surface area of rectangular prism is given by formula:

$A=2(wl+hl+hw)$

Where,

"l" is the length and "h" is the height and "w" is the width of prism

From given,

l = 18 cm

w = 6 cm

h = 3 cm

Substituting the values in formula,

$A = 2((6 \times 18) + (3 \times 18) + (3 \times 6))\\\\A = 2(108+54+18)\\\\A = 2 \times 180\\\\A = 360$

Thus surface area of rectangular prism is 360 square inches
