The expression (7-4i)-(3-12i) simplified is
Answer:
8i + 4
Step-by-step explanation:
Add/subtract like terms:
7 - 3
= 4
-4i - (-12i)
-4i + 12i
= 8i
Add these together:
8i + 4
So, the simplified expression is 8i + 4
Someone needed help with these questions, I couldn't answer it since two people are already answering it soo... Please help him/her!
First Question:
Follow PEMDAS
Parentheses, Exponents, Multiplication or Division, Addition or Subtraction
3 ÷ [tex]\frac{1}{4}[/tex] × (12 + 2³)
= 3 ÷ [tex]\frac{1}{4}[/tex] × (12 + 8)
= 3 ÷ [tex]\frac{1}{4}[/tex] × (20)
= 3 × 4 × 20
= 12 × 20
= 240
Second Question:
change the mixed number into an improper fraction:
[tex]3\frac{2}{3}[/tex] = [tex]\frac{11}{3}[/tex]
= [tex]\frac{11}{3}[/tex] ÷ [tex]\frac{3}{4}[/tex]
= [tex]\frac{11}{3}[/tex] × [tex]\frac{4}{3}[/tex]
= [tex]\frac{44}{3}[/tex]
rounded to WHOLE number: 14 containers

Neil got a hit 9 of the 11 times he batted in the softball tournament. Maggie got a hit 18 of the 22 times she batted in the tournament. Did they have the same batting records?
Answer:
they have the same batting record
Step-by-step explanation:
Batting record for each :
Neil :
9 /11 = 0.8181
Maggie :
18 /22 = 0.8181
From here we see that they both have the same proportion of hits :
Hence they have the same batting record

Step-by-step explanation:
One interior angle of a triangle is 60°. The other angle measures are x° and yº. Which of the following could be the values of
x and y? Select all that apply. X = 60, y = 60
X = 100, y = 20
X = 40, y = 80. x=50, y = 90
X = 45, y = 45
Answer:
x=60, y= 60
x=100, y= 20
x=40, y=80
Step-by-step explanation:
Triangles add up to 180 degrees. The ones above added to 60 equal 180.
60+60+60=180
100+20+60=180
40+80+60=180
Hope this helps! :)
Please helppp. Can you explain this?
Answer:
We have to find the value of x.
We need to substitute with 3 because they measure the same.
Step-by-step explanation:
(x - 1)
x - 1 = 3
x - 1 + 1 = 3 + 1
x = 4
(x + 1)
x + 1 = 5
x + 1 - 1 = 5 - 1
x = 4
Both answers are the same which means that they are correct.
Angela is making 25 sundaes with mint, chocolate, and vanilla ice cream. 3 5 of the sundaes are mint ice cream and 1 2 of the remaining sundaes are chocolate. The rest will be vanilla. How many sundaes will be vanilla?
Answer:
5
Step-by-step explanation:
Vanilla ice cream = 3/5 x 25 = 15
Remaining = 25 - 15 = 10
Mint ice cream = 1/2 x 10 = 5
Remainder = 10 - 5 = 5 = vanilla

Eli runs 5 meters per second.
On a coordinate plane, a line goes through points (1, 5) and (2, 10)..
Use the graph to identify the independent and the dependent variable. Check all that apply.
The two variables are Eli and 5.
The two variables are meters and seconds.
Meters are graphed on the x-axis.
Meters are graphed on the y-axis.
Seconds is the independent variable.
Seconds is the dependent variable.

Divide the answer by 4
11/4 ÷ 4 = 11/16
Each friend gets 11/16 pounds
I need help ASAP please
Answer:
B
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then
cos45° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{3}{c}[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )
c = 3[tex]\sqrt{2}[/tex]

Write a linear function f with the
values f(0) = 6 and f(4) = -6.
Answer:
f(x) = -3x + 6
Step-by-step explanation:
The general linear function is;
y = mx + b
it can also be written as (x , f(x))
f(x) = mx + b
where m is the slope and b is the y-intercept
so we have the points ;
(0,6) and (4,-6)
So we have;
for f(0) to be 6, it means that the y-intercept b is 6
This is because the value of x at the y-intercept is 0
So we have this as;
f(x) = mx + 6
Now, let’s substitute the other point so as to get m
For the other point;
x = 4 and f(x) = -6
that means;
-6 = 4m + 6
4m = -6-6
4m = -12
m = -12/4
m = -3
So we have the equation as;
f(x) = -3x + 6
Use the distributive property to expand (simplify): 13(9 + g)

The playroom on a blueprint is 3 cm by 8 cm. If the blueprint was drawn using a scale of 1 cm
= 5 ft, what are the actual dimensions of the playroom?
Answer:
15 feet by 40 feet
Step-by-step explanation:
if the original dimensions were 3 by 8 and 1 cm = 5 feet multiply 3x5 then 8x5 and you receive your answer.

If the area of a triangle with a base measuring 22 feet is 93.5 square feet, find its height.
Answer:
height = 8.5 feet
Step-by-step explanation:
Area of a triangle formula:
a=1/2bh
substitute what's given
93.5 = (1/2)22h
93.5=11h
divide both sides by 11 to isolate h
h=8.5 ft

Write the equation of the circle.
A: (x+3)2+(y−6)2= 2
B: (x−3)2+(y+6)2= 2
C: (x+3)2+(y−6)2= 4
D: (x−3)2+(y+6)2= 4
Answer:
C. (x + 3)² + (y - 6)² = 4Step-by-step explanation:
Get the center and radius from the graph.
Center is: (-3, 6)Radius is: 2Use the circle formula:
(x - h)² + (y - k)² = r²We have:
h = -3, k = 6, r = 2Substitute and get the equation:
(x - (-3))² + (y - 6)² = 2² ⇒(x + 3)² + (y - 6)² = 4Correct choice is C
in AABC, the measure of angle A=x degree, the measure of angle B=(2x)degrees, and the measure of angle C=(6x+18)degrees. What is the measure of angle B?
Answer:
m<B: 36
Step-by-step explanation:
x + 2x + 6x + 18 = 180
9x + 18 = 180
9x = 162
x = 18
m<B:
2x
2(18)
36
Answer:
m<B=36°
Step-by-step explanation:
The sum of angles in a triangle add up to 180°.
That means the sum of m<A+m<B+m<C=180°
We're given that:
m<A=x°
m<B=(2x)°
m<C=(6x+18)°
we can substitute those values as m<A, m<B, and m<C
x+2x+6x+18=180
combine like terms
9x+18=180
subtract 18 from both sides
9x=162
divide by 9
x=18°
we found the value of x, but we're not done yet
The question asks to find m<B, which is 2x°
in that case, we can substitute our known value to find the measure of <B
m<B=2x°
m<B=2(18)°
m<B=36°

A teacher is making a seating chart in order to group his class of 30 students. He puts 5 students in each group.
What should the teacher do to figure out how many groups he will have?
Answer:
The teacher should divide the amount of students by 5, that way they'll find how many groups they'll have. And the amount of groups they'll have is 6 groups of 5 students, you didn't ask for this part but I decided it'd be best to add it. Hope this helps, have an amazing day you awesome human! ^w^
