Answer:
30° and 110°
55° and 85°
70°and 70°
Step-by-step explanation:
Given that :
Angle B = 40°
Sum of angles in a triangle :
Angle (A + B + C) = 180°
A + 40 + B = 180
A + C = 180 - 40
A + C = 140°
From the Given options ;
The sun of the Angles Given must add up to 140°
Hence,
30° and 110° = 140°
55° and 85° = 140°
70°and 70° = 140
Here's an equation I need to solve:
x/2 +3 = 10
The first step is to subtract 3 from both sides:
x/2 = 7
What step do you do next to solve for x?
divide by 2
subtract 7
multiply by 2
add 7
Answer:
you multiply both sides by 2.

Add the following complex numbers: (2 + 3i) + (3 - 2i)
Answer:
5 + i
Step-by-step explanation:
Combine real part ans combine imaginary parts
2 + 3i + 3 - 2i = 2 + 3 + 3i - 2i
= 5 + i
Answer:
5 and 1i
Step-by-step explanation:
So you’re adding the following complex numbers: (2 + 3i) + (3 - 2i)
normally if you see a (-) in front of a number, that means it’s negative so we’re gonna think about this as -2i and positive 3.
so you’re gonna want to take the 2 regular while numbers (without the variable) and then add those together. they’re like numbers so neither of them have a variable, which means they can easily be added, but you can’t add a number like 7 to a number like 9h because there’s a variable.
Now that you’ve added the 2 and 3, you get 5 right? so now you’re gonna take the 3i and -2i, and add those together. since the number 3i is bigger than -2i, the ending number after you add those is gonna be positive, and it’s gonna be 1i.
now i’m not sure if you’re supposed to make an equation out of this but you’re answer will be 5 and 1i or 5 + 1i
also if you don’t want to put 1i, 1i is the same as just “i”. so you can put 5 + i :)

I am thinking of a number i multiply by 11 and add 22 i get the same answer if i miltiply by 4 and add 113 whats my number
Answer: 13
Step-by-step explanation:
Let the number that in thinking of be represented by x.
I multiply by 11 and add 22 will give the same answer as multiplying by 4 and adding 113. This.csn be firmed into an equation as:
(11 × x) + 22 = (4 × x) + 113
11x + 22 = 4x + 113
Collect like terms
11x - 4x = 113 - 22
7x = 91
x = 91/7
x = 13.
The number is 13

A bracelet that regularly sells for $44 is on sale for 15% off. Find the sale price of the bracelet. Use dollar signs with your answer. *
Answer:
The answer would be $37.40
Step-by-step explanation:
The sale price would be the current price which is 44 - 15% of itself.
It is 15 percent off, so 44 x 0.85 would be the equation, since the now price is 85 percent of the original price.
44 x 0.85 = 37.40
dollar signs ;)
Answer:
$33.00

Answer:
8
Step-by-step explanation:
If the area is 32 and the formula for area of a triangle is base * height / 2, and you have base = 8 and height = x and area = 32, this would be:
8 * x / 2 = 32
Now, solve:
[tex]8x/2=32\\4x=32\\x=8[/tex]
Answer:
x=8
Step-by-step explanation:
Area is equal to half of the base times the height. We are told that the area is 32and the base is 8, so we can write this equation:
32=1/2(8)h
Multiply 1/2 by 8:
32=4h
Divide both sides by 4:
h=8
So now we know that x (the height) equals 8.

Binomial has two terms
A. 7x+21
It is a binomial.
B. 3/x
It is not a binomial.
C. 8x²+6x+5
It is trinomial as it has three terms
