What property allows you to conclude that 5x+7x=12x

1 answer:

6 0

Since both of the numbers have a variable which is x ready to be multiplied, there is no expression leading to the variable therefore you will add normally but you will need to put the missing variable which needs to be multiplied. So overall you can just add and once you get your variable you can be abe to multiply and get your final answer.

Hope this helps

Solve the following equation for h. r+3Q/h=t

Arada [10]

Answer:

$\bold{h=\dfrac{3Q}{t-r}}$

Step-by-step explanation:

$\bold{r+\frac{3Q}h=t}\\-r\qquad\ -r\\\bold{\frac{3Q}h=t-r}\\\cdot h\qquad \cdot h\\ \bold{3Q=(t-r)h}\\^{\div(t-r)\quad\div(t-r)}\\\bold{\dfrac{3Q}{t-r}=h}$

Or, if you mean (r+3Q)/h=t:

$\bold{\frac{r+3Q}h=t}\\{}\ \ \cdot h\quad\ \cdot h\\\bold{r+3Q=ht}\\{}\ \ \div t\qquad \div t\\\bold{\dfrac{r+3Q}{t}=h}\\\\\bold{h=\dfrac{r+3Q}{t}}$

Geometry!!Find the area of the rhombus!!

mars1129 [50]

The area of a rhombus is half of the product of the lengths of the diagonals.

area = (7.5 yd + 7.5 yd)(13 yd + 13 yd)/2

area = (15 yd)(26 yd)/2

area = 390 yd^2/2

area = 195 yd^2

Answer: 195

Please help me find BD

Tanzania [10]

9514 1404 393

Answer:

14 units

Step-by-step explanation:

The angle bisector divides the sides proportionally, so you have ...

(x+4)/8 = (2x+1)/12

3(x +4) = 2(2x +1) . . . . . . multiply by 24

3x +12 = 4x +2 . . . . . . . . eliminate parentheses

10 = x . . . . . . . . . . . subtract (3x+2)

Then BD = x+4 = 10 +4.

The length of BD is 14 units.

Additional comment

The "triangle" cannot exist, as the side lengths are shown as 8, 12, and 35. The long side is too long. Nice math; bad geometry.
