Solve the equation for u.<br> Uw + uq=r

soldi70 [24.7K]

Answer: u= $\frac{r}{w+q}$

Step-by-step explanation:

uw + uq = r To solve for u factor the left side to eliminate the other variables.

u ( w + q) = r Now divide both sides by w+q

u = $\frac{r}{w+q}$

A square has an area of 561.69m2. Work out the perimeter of the square.

lara [203]

Answer:

The answer is 94.8 m

Step-by-step explanation:

Area of a square is a²

So, 23.7² = 561.69 m²

The side of the square is equal to 23.7 m

Perimeter of a square is the side multiplied by 4

So we have that 23.7 x 4 = 94.8 m

3) The length of JM is 9x + 6 units, the length of JK is

Vlada [557]

Answer:

$JM = 60 units$

Step-by-step explanation:

Given:

$JM = 9x + 6$

$JK = 5x$

$KM = 3x + 12$

$JK + KM = JM$ (segment addition postulate)

$(5x) + (3x + 12) = (9x + 6)$ (substitution)

Solve for x

$5x + 3x + 12 = 9x + 6$

Collect like terms

$5x + 3x - 9x = -12 + 6$

$-x = -6$

Divide both sides by -1

$x = 6$

$JM = 9x + 6$

Plug in the value of x

$JM = 9(6) + 6$

$JM = 54 + 6$

$JM = 60 units$
