|3y+7|-10=-5 add 10 to both sides

|3y+7|=5 now since this is an absolute value equation we must solve for both the positive and negative solutions...

3y+7=5 subtract 7 from both sides

3y=-2 divide both sides by 3

y=-2/3

Now

3y+7=-5 subtract 7 from both sides

3y=-12 divide both sides by 3

y=-4

So y=-2/3 and -4

Answer: $2061.55\ m$

Step-by-step explanation:

Given

The two communication mask are 2 km apart

Ubi's home is 500 m east of one of the mask

Suppose its distance from the other's is x

From the figure, we can write

$\Rightarrow x^2=2000^2+500^2\\\Rightarrow x^2=4\times 10^6+25\times 10^4\\\Rightarrow x=2061.55\ m\ \text{or}\ 2.061\ km$

Find the area:......Brainliest........

pav-90 [236]

Answer:

Step-by-step explanation:

The average length of the weird trapezoidal shape on the left is

(2 m + 10 m)/2, or 6 m. The width is 4 m, so the area is 24 m^2.

The area of the semicircle is (1/2)(pi)(2 m)^2, or 2pi m^2.

Thus, the overall area of the green shape is 24 m^2 + 2pi m^2.
