Rearrange<br> x= v+5<br> to make v the subject.

Darina [25.2K]

$x = v + 5$

$x - 5 = v + 5 - 5$

$x - 5 = v$

$v = x - 5$

The perimeter of a right triangle is 24 ft, and one of its legs measures 6 ft. Find the length of the other leg and the hypotenu

Mrrafil [7]

Answer:

Step-by-step explanation:

We know the perimeter of a triangle is the sum of all the sides( two legs and one hypotenuse).

By pythagoras we know that

$h^2= a^2+b^2.$

and the perimeter is $P=h+a+b$ .

Since P=24 and a=6 we have these equations:

$h^2=36+b^2\\24=h+6+b$

From the last equation we have $h=18-b$ . Replace h in the first equation we get that

$(18-b)^2=36+b^2$

$18^2-36b+b^2=36+b^2\\288=36b\\b=\frac{288}{36}=8$

and h=18-8=10

The polygons in each pair are similar. Find the missing side length.

Taya2010 [7]

Answer:

Step-by-step explanation:

If you flip the polygon on the right so it looks like the polygon on the left, the scale factor for the small polygon to the big polygon is 32/40 or 4/5.

Now use that scale factor, 4/5, to find the missing length

4/5 = ?/15

5*3 = 15 so 4*3 = ?

? = 12

The low temperature for 5 days was -5, -7, -2, 2, -3 degrees. What was the average low temperature for those days?

Greeley [361]

The average would be -3. You add all the low temps up and get -15 then you divide it by the amount which was 5 temps... And get -3.
