2x=3x-5
isolate the x so:
2x-3x=3x-3x-5
-x=-5
x=5

we know 2x=3x-5 because of they share an side have the same angles and have a leg of the same value.

Can someone turn 4,971 into a scientific notation
Illusion [34]

We need to divide 4,971 by 10 until its a number less then 10.

4,971 / 10 = 497.1

497.1 / 10 = 49.71

49.71 / 10 = 4.971

Now, 4.971 is less then 10, so, we can write this into scientific notation.

4.971 * 10^?

We need to know what power we add to 10 to get 4,971. We can solve for looking at the number of times we divided. As you can see above, we divided 3 times so that will be the power of 10.

4.971 * 10³

Best of Luck!

The volumes of two similar square pyramids is 128 and 250 meters respectively. The side length of the smaller pyramid is 8 meter
Yuliya22 [10]

Answer:

Height of bigger square pyramid = 3.072 meter

Step-by-step explanation:

Using equivalent ratios to find the side of the bigger square prism

128:8 = 250:X

X = (250 x 8) ÷ 128 = 15.625

Volume of a square pyramid = a x a x h/3

Hence to evaluate the height

250 = 15.625 x 15.625 x h/3

H = 3.072 meters

Write the equation of a line that goes through point (0,-8) has a slope of 0
Deffense [45]

Answer:

y = x - 8

Step-by-step explanation:

In the equation for slope, y = mx + b,

your slope being 0 makes the equation 'x' or 0x but x is preffered.

Your why would be -8 because there is no x in the point and it is a negative number.
