5 0

Answer:

Subtract: 5 - 9i = 5-9i  

Add: the result of step No. 1 + (-4) = (5-9i) + (-4) = (5-4) + (-9i) = 1-9i  

Add: the result of step No. 2 + 7i = (1-9i) + 7i = 1 + (-9+7)i = 1-2i

Subtract: 1 - 2i = 1-2i  

Subtract: the result of step No. 1 - 4 = (1-2i) - 4 = (1-4) + (-2i) = -3-2i  

Add: the result of step No. 2 + 7i = (-3-2i) + 7i = -3 + (-2+7)i = -3+5i

Step-by-step explanation:

Correct me if I'm wrong pls and ty :).

irga5000 [103]
Since, each side of the fence should have the 1 3/4 feet wide decorative piece, the width of the fence should be subtracted by 2 pieces (1 3/4 feet)
                                 = 26.5 feet
Then, divide the remaining width by 4.5 feet and the answer is 5.88. Thus, approximately 5 pieces of the 4 1/2 feet should be installed.

kobusy [5.1K]

Answer:

The answer is below

Step-by-step explanation:

An equation shows the relationship between two or more variables. An equation is a statement that shows the equality between expressions. An equation with infinitely many solution is when all numbers are solutions, that is there is no one solution. Example is: x + 3 = x + 3.

When each side of an equation has been simplified, equations that have the same coefficients and the same constants on each side have infinitely many solutions

two trains leaves stations 320miles apart at the same time and travel toward eachother. One train travels at 110 miles per hour
I am Lyosha [343]

x/110 = (320-x)/90

<span> Cross multiply</span>

90x = 35200-110x

200x=35200

X = 35200/200 = 176 (distance traveled by train going 110 mph

176/110 = 1.6 hours = 1 hour and 36 minutes

 

Check: 110*1.6 = 176, 90*1.6 = 144

176+144 = 320

it will take 1.6 hours ( 1 hour 36 minutes) for the trains to meet
