A number multiplied by 4 is -20

2 answers:

7 0

-5 would be the answer. 4 times -5 would equal -20 because 4 times 5 equals 20 and a positive number times a negative number equals a negative number. (opposite signs equal negative, same signs equal positive)

If you liked my answer, make sure to leave this answer a Branliest! (:

4x = -20

divide by 4 on both sides (4/4 cancels itself out) (-20 / 4 = -5)

x = -5

4 (-5) = -20

-20 = -20

<u>The answer is -5</u>

On a sunny day, a flag pole and its shadow form the sides of a right triangle. if the hypotenuse is 35 meters long and the shado

Triss [41]

We can use Pythagorean's Theorem in order to find the remaining side length
a^2+b^2=c^2
Let a be the shadow length
Let b be the height of the flagpole
Let c be the hypotenuse
28^2+b^2=35^2
784+b^2=1225
b^2=1225-784
b^2=441
b=√441
b=21
Therefore the flagpole is 21 meters tall.
Hope this helps!

Find the measure of.. (Image included) <br> I'll take all the help I can get please :)

Answer:

$\sf\Huge\boxed{C.40}$

Step-by-step explanation:

Hello There!

Remember: sum of interior angles of a triangle = 180

so to find x we use this equation

180 = 90 + 7x + 5 + 9x + 5 ( the little square in the triangle indicates that the angle is a right angle. right angles have a measure of 90 so that's where the 90 came from.)

now we solve for x

step 1 combine like terms

90 + 5 + 5 = 100

7x + 9x = 16x

now we have 180 = 16x + 100

step 2 subtract 100 from each side

180 - 100 = 80

100 - 100 cancels out

now we have 80 = 16x

step 3 divide each side by 16

80/16 = 5

16x/16=x

we're left with x = 5

Finally we plug in 5 into x for angle a

7(5)+5

7*5=35

35+5=40

so we can conclude that the measure of angle A is 40 degrees

at the beginning of the day stock cuz opened at $7.25 at the end of the day it closed at $6.88 what is the rate change of stock

Vsevolod [243]

The absolute change is the difference: 6.88 - 7.25 = -0.37

The rate of change is that divided by the originalprice x 100

Ratre of change: (-0.37/7.25 )*100 = -4.93%
