Answer:

x= 1.24

Step-by-step explanation:

First step is to move the variable to one side. To do that, the smallest variable needs to be subtracted or added.

3x+4/5= 7-2x

+2x +2x

Now that it has been moved to one side, isolate the variable. Subtract 4/5 to both sides.

5x+4/5= 7

-4/5 -4/5

(4/5 is 0.80, so subtract 0.80 from 7)

5x= 6.2

Now divide 5 to both sides.

5x=6.2

Answer:

Step-by-step explanation:

3x + 4/5 = 7 – 2x

Multiply each term by 5

15x + 4 = 35 -10x

15x + 10x = 35 - 4

25x = 31

x = 31/25

x = 1 6/25

A pilot can travel for 140 miles with the wind in the same amount of time as 360 miles against the wind. Find the speed of the w

quester [9]

Answer:

-88 mph

Step-by-step explanation:

We can use the relation ...

time = distance/speed

to compare the times in the two directions.

$\dfrac{140}{200+w}=\dfrac{360}{200-w}\\\\140(200-w)=360(200+w)\\\\200(140-360)=w(360+140)\\\\w=\dfrac{200(-220)}{500}=-88 \quad\text{miles per hour}$

The wind speed is -88 miles per hour.

_____

The problem statement tells us the travel is slower with the wind than against the wind. Hence "with the wind" must be subtracting from the net speed. That is, the wind speed is negative.

A function g is defined by g:x→3−2sinx,for 0◦ ≤x≤A◦,where A is a constant.

Crank

hmmm: g maps x onto 3-2sin(x) for all x from 0 to A degrees g(x) = 3-2sin(x) the inverse would have to be arcsin (3-x)/2, which only has a radian output between -pi and pi i believe. but this is just from memory

7nadin3 [17]

Answer:

a) -27 a³ b⁶

Step-by-step explanation:

Explanation:-

Given ( -3 ab² )³

By using (ab )ⁿ = aⁿ bⁿ

( -3 ab² )³ = (-3)³ a³ (b²)³

Again , using formula $(a^{m} )^{n} = a^{mn}$

= -27 a³ b⁶
