Como resolver y=1-2.5

1 answer:

7 0

I don't really speak Spanish but I'll guess that says

How do I solve y = 1 - 2.5

Unless I'm missing something, there's not even any algebra here.

The way we subtract a bigger number from a smaller number is first we subtract the smaller number from the bigger number the regular way, then we prepend a minus sign.

y = 1 - 2.5 = -(2.5 - 1) = -1.5

Answer:

See below

Step-by-step explanation:

For women, the initial number is 6, constant rate of change is w, number of years is x.

Find the rate of change and work out the required formula:

10w + 6 = 391 ⇒ 10w = 385 ⇒ w = 38.5

Formula:

W(x) = 38.5x + 6

Similarly for men, we get:

10m + 25 = 410 ⇒ 10m = 385 ⇒ m = 38.5

Formula:

M(x) = 38.5x + 25

First of all, let's divide.

Can someone please help me with this

omeli [17]

Answers:

x = 3
CD = 21
DE = 16
CE = 21

=============================================================

Explanation:

The congruent base angles are D and E. Opposite those angles are the sides CE and CD. These opposite sides are the same length.

CE = CD

16x-27 = 4x+9

16x-4x = 9+27

12x = 36

x = 36/12

x = 3

This x value then leads to the following:

CD = 4x+9 = 4*3+9 = 12+9 = 21
DE = 7x-5 = 7*3-5 = 21-5 = 16
CE = 16x-27 = 16*3-27 = 48-27 = 21

We see that CD and CE are both 21 units long, which helps confirm we have the correct x value.
