Answer:
k = 16
Step-by-step explanation:
Isolate the variable, k. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
Subtract 67 from both sides of the equation:
k + 67 = 83
k + 67 (-67) = 83 (-67)
k = 83 - 67
k = 16
16 is your answer for k.

g^5-h^3 if g= 2 and h= 7
Answer:
-318
Step-by-step explanation:
2^5 - 7^3
25 - 343
= -318
Answer:
[tex]\boxed{\tt -311}[/tex]
Step-by-step explanation:
We are given the expression:
[tex]g^5-h^3[/tex]
and asked to solve when [tex]g=2[/tex] and [tex]h=7[/tex].
Substitute 2 in for g and 7 in for h.
[tex](2)^5-(7)^3[/tex]
Evaluate the exponents.
⇒ 2⁵= 2*2*2*2*2= 32
[tex]32-(7)^3[/tex]
⇒7³= 7*7*7=343
[tex]32-343[/tex]
Subtract 343 from 32.
[tex]-311[/tex]
The expression g⁵-h³ evaluated for g=2 and h=7 is equal to -311
Two times the complement of an angle is 23 less than the supplementary of the angle. What is the measure of the angle?
Answer:
Step-by-step explanation:
Let the angles be x and y
If the two angles are complementary then their sum is 90 i.e x+y = 90
x = 90-y
If the two angles are supplementary, then their sum is 180 i.e x+y = 180
x = 180-y
If two times the complement of an angle is 23 less than the supplementary of the angle, this is written as;
2(90-y) = (180-y)-23
180-2y = 157-y
-2y+y = 157-180
-y = -23
y = 23
Hence the angle is 23°
7. A recipe for 12 people needs the following ingredients. Brian is going to adjust the recipe
for 3 people.
4 whole eggs
4 1/4cups of sugar
7 cups of flour
41/2cups of milk.
Part A
How much flour will Brian need if he is making it for 3 people?
Part B
How much sugar will be needed if he is making it for 3 people?
Answer:
A. Brian will need 1.75 (1 3/4) cups of flour
B. Brian will need 1 1/16 cups of sugar
Step-by-step explanation:
Brian wants to make it for 3 people, so everything must be divided by 4 since 12/4=3.
7/4=1.75
4 1/4 divided by 4=1 1/16
Answer:A is 21 cups of flour and B is 12 3/4 cups of sugar
Step-by-step explanation:
A is 21 because 7x3 is 21 and B because 4 1/4x3 equals 12 and 3/4 cups
Find MN
LM = 3y + 4
MN = 7y + 9
LN = 143
Answer:
B. 100
Step-by-step explanation:
[tex]3y+4+7y+9=143[/tex]
[tex]10x+13=143[/tex] 143-13=130
10x=130 divide both sides by 10 130/10= 13 x=13
MN=7(13)=91+9=100
LN=3(13)=39+4=43
100+43
Jose wants to buy his friends pizza at lunch. He has $36 to spend. The pizza costs $2.25 per slice. Which equation could be used to find the number of slices, x, he can buy?
Answer:
36 = 2.25(x)
Number of slices = 16 slice
Step-by-step explanation:
Given:
Total amount spend = $36
Cost of each slice = $2.25 per slice
Number of slices = x
Find:
Equation
Computation:
Total amount spend = Cost of each slice × Number of slices
36 = 2.25(x)
x = 16
Number of slices = 16 slice
A) A plane takes off at 50 feet below sea level and climbs 1,542 feet. At what altitude is the plant currently flying?
B) How much higher does the plane have to climb to reach 3,400 feet?
Make sure you answer both parts of the question and label each part of the question.
Answer:
A) 1,492
B) 1,908
Step-by-step explanation:
A) The equation set up for this part is 1,542-50=1,492 We know that we're subtracting 50 from 1,542 because it say that the plane starts below sea level.
B) The equation set up for this part is 3,400-1,492=1,908 We know that we're subtracting the answer from part A from 3,400 because the plane will need to climb the difference in order to reach 3,400.

x/2 inches
Step-by-step explanation:
Describe the steps of constructing a segment that is TWICE as long as the given segment BD.
Answer:
See below
Step-by-step explanation:
From the segment BD, I will consider the point B as the begin and D as the end of the vector, therefore [tex]\overrightarrow{BD} = \vec{v}[/tex]
Once you want a segment that is twice as long as the given segment, we may say that the magnitude of the vector is
[tex]||2\vec{v} || = \sqrt{(2x)^2 + (2y)^2} = \boxed{ \sqrt{4x^2 + 4y^2} }[/tex]
Note: I'm assuming [tex]\vec{v} \in E^2[/tex], which means the segment is in the plain.

1) Which expression represents the volume
of a shipping box?
Answer:
(s+2)^3
Step-by-step explanation:
I think this is referring to a square as a box, so the length of a jewelry box would be s. We learn that a shipping box is 2 inches longer, so s+2 = the length of the shipping box.
Volume = Length*Width*Height, but if square, all dimensions are the same, so s+2 to the power of 3 would be your answer.
Answer:answer (s+2)^3

Given f(x) = 4(x - 8), determine the value of f(10).
Answer:
f(10) = 8
Step-by-step explanation:
f(x) = 4(x - 8)
Let x = 10
f(10) = 4 ( 10-8)
= 4 ( 2)
= 8
Here, we are provided with a polynomial in x and it's general value in variable X is also given.
[tex]f(x) = 4( x - 8)[/tex]
We need to find the value of f(10)
For this, we need to substitute the value of x with 10, because we are required to find f(10)
Given polynomial, f(x) = 4(x - 8), Putting value of x
[tex]f(10) = 4(10 - 8)[/tex]
[tex]f(10) = 4(2)[/tex]
[tex]f(10) = \boxed{ \red{8}}[/tex]
This is our required answer !!

Find the coordinates of the other endpoints of the segment, given its midpoint and one endpoint. Midpoint (-14, -18), endpoint (-18,-13)
Answer:
Step-by-step explanation:
(x - 18)/2 = -14
x - 18 = -28
x = -10
(y - 13)/2 = -18
y - 13 = -36
y = -23
(-10, -23) the other endpoint
Using the information that
5.2 x 67 = 348.4
write down the value of
a) 52 x 67
b) 5.2 x 6.7
c) 348.4 - 52
Answer:
Below in bold.
Step-by-step explanation:
a) 52 = 5.2 * 10 so the result is 348.4 * 10 = 3484.
b) 6.7 is a tenth of 67 so the result is 348.4 / 10 = 34.84.
c) 348.4 - 52 = 296.4.

What is 3.18 written as a rational?
Answer:
[tex]\frac{318}{100}[/tex]
Step-by-step explanation:
A rational number can be expressed as
[tex]\frac{a}{b}[/tex] ← where a and b are integers
The 8 in 3.18 is in the hundredths position, thus
3.18 = [tex]\frac{318}{100}[/tex] ← as a rational number

What does it mean when a function is one-to-one?
Let a function be defined from A to B then f is said to be one to one function if every element of domain has its unique image in co- domain . In other words, if each separate elements of set A are mapped with separate of set B then such function is known as one to one function.
What is this?
[tex] \frac{f}{4} - 5 = - 9[/tex]
I don't know this one bruh
Hey there!
ANSWER: [tex]f=-16[/tex]EXPLANATION:[tex]\frac{f}{4}-5=-9[/tex]
Simplify both sides and you get:
[tex]\frac{1}{4}f-5=9[/tex]
Now add 5 to both sides and you get:
[tex]\frac{1}{4}f=-4[/tex]
Now you have to multiply both sides and you get:
[tex]f=-16(ANSWER)[/tex]
Hope this helps!
