(-1 + 5i) + (-2 - 3i)

Answer:

300

Step-by-step explanation:

Answer:

x = -3

y = 8

Step-by-step explanation:

x + 2y = 13    ------------(I)

    x  = 13 - 2y -----------(II)

-2x - 3y = -18 ----------(III)

Substitute x = 13 - 2y in equation (III)

   -2*(13 - 2y)  - 3y = -18

-2*13 - 2y *(-2) -3y = -18

  -26  + 4y  - 3y    = -18             {Combine like terms}

               -26 + y =  -18     {Add 26 to both sides}

                         y = -18 + 26

                         y = 8

Substitute y = 8 in equation (II)

x = 13 - 2*8

  = 13 - 16

x = -3

x = -3

y = 8

Answer:

9 miles

Step-by-step explanation:

You need to get 27 minutes to 81 minutes so you multiply 27 by 3, and that is 81, so you simply multiply 3 by 3 and get 9! Hope this helps! ;)

(27 x 3) = 81

(3 x3) = 9

Answer:

375

Step-by-step explanation:

Answer:

x=8

Step-by-step explanation:

Answer:

95 in.²

Step-by-step explanation:

Total surface area of the rectangular pyramid = 4(area of triangle) + area of rectangle

Area of triangle = ½*base*height

base = 5 in.

height = 7 in.

Area of triangle = ½*5*7 = 17.5 in.²

Area of rectangle = Length*width = 5*5 = 25 in.²

Plug in the values

Total surface area of the rectangular pyramid = 4(17.5) + 25

= 95 in.²

Answer:

AC bisects BCD

Reason: The angles in the resulting triangles are congruent.

Answer:

A triangle‘s angles should add up to 180 and the given angles sum up to 130 so x + 58 = 50 so x = -8

Hope this helped and brainliest please

Answer:

-8

Step-by-step explanation:

-8+58=50

50+53+77=180

triangles angles should equal 180

Answer:

The ratio of juices to ginger ale is 2 to 2

The ratio of orange juice to the cranberry juice is 1 to 1

Step-by-step explanation:

Ginger ale = 2 liters

Orange juice = 1 liter

Cranberry juice = 1 liter

Total ratio = 2 + 1 + 1 = 4

The ratio of ginger ale to the entire punch bowl is 1 to 4.

Ginger ale : entire punch bowl

= 2 : 4

= 1 : 2

Not true

The ratio of orange juice to ginger ale is 2 to 1.

Orange juice : ginger ale = 1 : 2

Not true

The ratio of juices to ginger ale is 2 to 2.

juices : ginger ale = orange juice + cranberry juice : ginger ale

= 1 + 1 : 2

= 2 : 2

True

The ratio of the entire punch bowl to the juices is 2 to 4.

Entire punch bowl : juices 4 : 2

Not true

The ratio of orange juice to the cranberry juice is 1 to 1.

Orange juice : cranberry juice = 1 : 1

True

Answer:

5x-8=90

5x=90+8

5x=98

x=98/5

x=19.6

5(19.6)-8

Answer:

7.99+2(1.09)+3(2.75)+x =25

Step-by-step explanation:

what's given are the prices of the canvas, brushes, and bottles of pain. 7.99 represents the one canvas Anna is buying, 2(1.09) represents the 2 brushes, and 3(2.75) represents the bottle of paints. Now what's left is x and x represents the amount of money left on the gift card. The gift card is $25 in total so that's why at the end of the equation it equals to $25.

Answer:

7/26

Step-by-step explanation:

First, find the probability of pulling out a big marble.

Since there are 7 big marbles, and 26 in total, the probability is 7/26

Now, find the probability of pulling out a small marble after the replacement.

There are 6 small marbles and 26 in total, so the probability is 6/26. This can be simplified by dividing each side by 2. This will get you 3/13

To find the probability of both of these happening, multiply the probabilities by each other:

(7/26) x (3/13)

= 7/26

So, the probability is 7/26

Answer:

Two negative make a positive so this equation is basically 39 = n + 12 so you need to subtract 12 from each side. This makes it n = 27

Hope this helps!
