Answer:
-1 -9i, where a = -1 and b = -9
Step-by-step explanation:
1st step is to open up the brackets. Since there's a (-) in front of the second bracket, we have to multiply every term by -1, so positive becomes negative, negative becomes positive etc.
4-i-5-8i
Then we collect like terms.
-1 -9i
This is the answer. It looks wrong since the variables are 'positive' in a +bi, but you have to remember that a variable can be represented as a, but its actual value could be negative, in this case -1. This is the same with b, as b could be the same as -9.
This is an expression, so we can't multiply everything by -1 to make it 'look right'. You can only multiply by -1 or 'alter' the terms when the expression equates to something.

In the figure, angle E measures 54° and angle G measures 29°. What is the measurement of angle H?
A.
25°
B.
34°
C.
97°
D.
126°
Answers
Answer:
H=97 degrees or choice "C"
Step-by-step explanation:
Assuming this is a triangle:
All triangles contain 180 degrees, so:
180=E+G+H, or H=180-E-G
H=180-54-29
H=97
H=97 degrees or choice "C"

Tyler has a baseball bat that weighs 28 ounces. Find this weight in kilograms and in grams. Explain or show your reasoning. (Note: 1 kilogram 35 ounces)
Answers
Answer:
Weight in Kilograms = 0.8 Kilograms
Weight in grams = 800 grams
Step-by-step explanation:
Tyler has a baseball bat that weighs 28 ounces.
a) Weight in Kilograms
From the question:
1 kilogram = 35 ounces
Hence:
35 ounces = 1 kilogram
28 ounces = x kilogram
Cross Multiply
35 × x = 28 × 1
x = 28/35
x = 0.8 kilograms
b) Weight in grams
1 kilogram = 1000 grams
0.8 kilogram = x
Cross Multiply
x = 0.8 × 1000 grams
x = 800 grams

Chad has a bag with 2 mint sticks, 11 jelly treats, and 7 fruit tart chews. If he eats one piece every 4 minutes, what is the probability his first two pieces will be a jelly treat and a mint stick and represent as a percent to the nearest tenth if necessary?
Answers
Answer:
first you add all the candies together to get 20 in the bag
2+11+7=20
jelly treat:
now we divide 11 by 20 to get a decimal
11/20= .55
multiply .55 by 100 to change it to a percentage
.55*100=55
first part of answer: He has a 55% chance of getting a jelly treat
mint stick:
divide 2 by 20 to get a decimal
2/20=.1
change .1 to a percent by multiplying by 100
.1*100=10
second part of answer: he has a 10% chance of getting a mint stick

Answer:
[tex]2x(4x+3)[/tex]
Step-by-step explanation:
The first thing to factorising this expression is to find the greatest common factor (GCF). For 8x² and 6x the gcf is 2x. So now we divide the 8x² and 6x by the 2x. Which comes out to 4x and 3, these will be inside the parentheses.
So it'll factorise to [tex]2x(4x+3)[/tex] and remember when we are dividing with exponents we subtract the exponents. So [tex]\frac{8x^2}{2x}[/tex] we will divide the coefficients together that'll be 4 and now for the exponents the 2 on the x² minus the 1 on the x will equal 1 so it'll be just x we don't place a one or anything.

Argyle sells computers. He keeps one
eighth of his sales as a commission.
How much must he sell to earn $500?
Answers
Answer:
Note: I'm assuming that he keeps 1/8 of the money spent for himself.
If this is what the question was asking, then the answer would be:
Argyle must sell $4,000 worth of computers.
Step-by-step explanation:
First, we write an equation.
1/8n = $500
Note: n is the variable I'm using to represent the amount of money Argyle must sell to get $500 as commission.
Then, to get the value of n and to get rid of the fraction, we multiply both sides by 8:
1/8n * 8 = $500 * 8
= n = $4000
Therefore, Argyle must sell $4,000 worth of computers to keep 1/8 ($500) as commission.

Find WZY. (helpp fast)
Answers
Answer:
[tex]m\angle WZY = 24^\circ[/tex]
Step-by-step explanation:
Angles and Lines
The figure shows two triangles WXZ and WYZ. Considering:
* Angles WXZ and WYZ are right (90°)
* Sides XW and YW are congruent (red marker on both)
* They share the side WZ.
We can conclude they are congruent. Thus, angles XZW and YZW are congruent or have the same measure:
5x + 4 = 6x
Subtracting 5x:
4 = x
Or, x =4
Thus:
[tex]m\angle WZY = 6x = 24^\circ[/tex]
[tex]\mathbf{m\angle WZY = 24^\circ}[/tex]

Answers
Answer:
132 degrees
Step-by-step explanation:
One sit of the 48 degrees is 48 degrees, so that opposite will be the same. Add them up, get 96. There is a full 360 degrees circle, so get 360 and subtract 96 from it, to get 264 degrees. That is the top and bottom angle of the right side, so just divide it in two
Answer:
I think x= 84
if the lines are parallel then the angle should be the same. Because one angle =48° the other side is likely to equal the same. Add 48+48, subtract 180 from your answer and that's how you get 84°. hope this helps
