Answer: j=0.4

-j+0.8=-0.9j+0.76

-j+0.8+0.9j=-0.9+0.76+0.9j

-0.1j+0.8=0.76

-0.1+0.8-0.8=0.76-0.8

-0.1j=-0.04

-0.1j/-0.1=-0.04/-0.1

j=0.4

Ya have a good day.

Answer 0.4
Regroup terms: 0.8 - j= -0.9j + 0.76
Add j to both sides: 0.8 = -0.9j + 0.76+j
Simply : 0.8=0.1×j+0.76
Subtract: 0.76 from both sides 0.8-0.76=0.1x j
Simplify 0.8−0.76 to 0.04: 0.04= 0.1×j
Divide both sides by 0.1: 0.04/0.1=j
Simply 0.04/0.1 to 0.4: 0.4 =j
Switch sides: j= 0.4

Michel started to drive from New York to Washington, DC, which is 120 miles away, at 7:00 AM. For the first hour and a half of h

san4es73 [151]

Answer:

30 mph

Step-by-step explanation:

First we need to find the distance travelled in the first 1h30m.

We can do that multiplying the speed by the time travelled, so we have:

Distance1 = 50 * 1.5 = 75 miles

If the total distance is 120 miles, Michael still needs to travel 120 - 75 = 45 miles.

And if the total time travelled is 3 hours (10 AM - 7 AM), the second part of the travel has a duration of 3h - 1.5h = 1.5h

So if the distance is 45 miles and the time is 1.5 hours, we can find the speed of the second part:

45 = speed * 1.5

speed = 45/1.5 = 30 mph

HELPPP !! If O N = 8 x − 8 , L M = 7 x + 4 , N M = x − 5 , and O L = 3 y − 6 , find the values of x and y for which LMNO must be

sveticcg [70]

Answer:

x=12 and y=4.3

Step-by-step explanation:

Given the sides of quadrilateral that are O N = 8 x − 8 , L M = 7 x + 4 , N M = x − 5 , and O L = 3 y − 6. we have to find the value of x and y so that LMNO be a parallelogram.

we know opposite sides of parallelogram are equal.

Hence, we have to find the value of x and y such that opposite sides becomes equal which implies LMNO is a parallelogram.

Equating opposite sides equal, we get

8x-8=7x+4 ⇒ 8x-7x=8+4=12 ⇒ x=12

implies, NM=x-5=12-5=7

NM=OL ⇒ 3y-6=7 ⇒ 3y=13 ⇒ y=4.3

Hence, x=12 and y=4.3
