Answer:

x = 7/3

Step-by-step explanation:

4x - 2 = x + 3 + 2

4x - 2 = x + 5

Rearranging the terms, we get,

4x - x = 5 + 2

3x = 7

x = 7/3

Hence, x = 7/3.

A farmhouse shelters 11 animals. Some are goats and some are ducks. Altogether there are 34 legs. How many of each animal are th

andriy [413]

We are given that there are 11 animals with a total of 34 legs.

Let G = number of Goats, and D = number of Ducks

then G + D = 11; solving for G, we get G = 11 - D

then, 4G + 2D = 34

substituting the value for G, we get 4(11 - D) + 2D = 34

expanding, we get 44 - 4D + 2D = 34

solving, we get D = 5. Therefore, G = 6

Proof: (5 x 2) + (6 x 4) = 34

(-19+7i)-(29+32i)=<br><br> in the form (a+bi)

olga_2 [115]

ANSWER

$-48-25i$

EXPLANATION

We want to simplify the expression,

$(-19+7i) - (29+32i)$

Let us expand the bracket to obtain,

$-19+7i-29-32i$

We now group the complex number parts and real number parts.

$-19 -29+7i-32i$

We simplify further to obtain,

$- 48-25i$

This is in the form,

$a+bi$

where

$a=-48$

and

$b=-25$
