I think it is (0,-1)
Divide 100 by 16 and write the answer as a mixed number. Reduce the
fraction part of the mixed number.
Answer:
Step-by-step explanation:
Divide 100 by 16 and you get 6.25 then turn it into a mixed number which would be 6 25/100 then reduce 25/100 by dividing 100 by 25 and 25 by 25 which will give you 1/4 so the answer is 6 1/4.Welcome!

Pre-algebra 2x+56=22 and -99+-51=60 also 5(- 3x - 2) - (x - 3) = -4(4x + 5) + 13 and (-4 , -5) and (-1 , -1). Solve Now for brainly big brain people can only solve this question!!!
Answer: 17
Step-by-step explanation:
2x + 56=22
- 56 -56
2x = -34
divide 2x by both sides
x = -17
Refer to the equation x - 5y = 20.
(a) Create a table of values for at least 4 points. Show your work.
(b) Use the table of values to graph the line.
Answer:
Kindly check explanation
Step-by-step explanation:
Given the equation :
X - 5y = 20
x - 20 = 5y
(x - 20) / 5 = y
x = - 5
y = (-5 - 20) / 5 = -5
x = 0
y = (0 - 20) / 5 = - 4
x = 5
y = (5 - 20) / 5 = - 3
x = 10
y = (10 - 20) / 5 = - 2
X : _____ - 5 ___ 0 ____ 5 ____10
y : _____ - 5 ___- 4 ___ - 3 ___ - 2
Kindly make use of a graph for better clarity and accuracy
Suppose m<3=127 degrees. Find m<1.
Answer:
m∠1 = 37°
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesGeometry
Definition of a Line: A line is 180°All angles in a triangle add up to 180°Step-by-step explanation:
Step 1: Define
m∠3 = 127°
m∠G = 90°
Step 2: Find m∠2
Set up equation: m∠2 + 127 = 180Isolate unknown: m∠2 = 53°Step 3: Find m∠1
Set up equation: m∠1 + m∠2 + m∠G = 180Substitute: m∠1 + 53 + 90 = 180Combine like terms: m∠1 + 143 = 180Isolate unknown: m∠1 = 37°2(x - 5) = 9 -3x + 6 + 8 + 3x + 7
Answer:
x = 20
Step-by-step explanation:
2(x - 5) = 9 - 3x + 6 + 8 + 3x + 7
2x - 10 = 9 - 3x + 6 + 8 + 3x + 7
2x = 10 + 6 + 8 + 7 + 9
2x = 40
x = 40 ÷ 2
x = 20
Thus, x = 20

Demarcus has at least $8 more than his
older sister. His older sister has $4.
Which of the following inequalities could
be used to find how much money, m.
Demarcus has?
Om> 8+4
8 - m < 4
8m > 4
HELPPPPPP PLEASE
Answer:
8m > 4
Step-by-step explanation:
8m, (the amount of money Demarcus has), is more than how much money his older sister has, (4), so 8m is greater than (>) 4
Answer:
8m > 4 is the correct answer:)
2 is 12.5& of the number
Answer:
if you ment to say 2 is 12.5% of what number the answer would be 16
Step-by-step explanation:
Write down what you know with x as the number you need to find.
Of is always "multiply"
Choose another way to write 12.5%
2 =12.5% of x
So 2 = 0.125xx
x= 2 *over*0.125
x=16
Answer:
x=16
Step-by-step explanation:
Let the number be x.
if they say 12.5% of a number, this means that 12.5/100 *x which will be :
12.5/100x
make it an equation (a true one)
12.5/100x=2
divide.
2 divided by 12.5/100x would be
x=16!

The table below represents a linear function f(x) and the equation represents a function g(x):
x f(x)
−1 −6
0 −3
1 0
g(x)
g(x) = 4x − 5
Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)
Part B: Which function has a greater y-intercept? Justify your answer. (4 points)
Answer:Assuming the problem is for the linear functions:
f(x) = -1-50-113 g(x) = -51-113*(2x-7) = -226x+740
g(x) = 2x-7

Answer:
∠AMC = 75
Step-by-step explanation:
ΔABC,
∠C = 90° ; ∠B = 30°
∠A + ∠B +∠C = 180 {Angle sum property of triangle}
∠A + 30 + 90 = 180
∠A + 120 = 180
∠A = 180 - 120
∠A = 60°
In ΔACM,
∠ACM = 90/2 = 45° { CM is angle bisector}
∠ACM + ∠AMC +∠A = 180 {angle sum property}
45 + ∠AMC + 60 = 180
∠AMC + 105 = 180
∠AMC = 180 - 105
∠AMC = 75

From a collection of 124 poems, 36 are sonnets, 42 are odes, and 46 are free verse. A poem is
selected from the collection at random. Find the probability that it is a sonnet or an ode. Express
your answer to the nearest whole percent.
A 49 percent
B 63 percent
C 83 percent
D 77 percent
Answer:
63
Step-by-step explanation:
36 is approximately 30% of 124 and 42 is approximately 33% of 124, so 30 + 33 = 63
Answer:
Answer, B
Step-by-step explanation:
add the odes and sonnets, and find the percentage of 78/124 which is 62.9% rounded to 63%.
The age of a cat 2 years or older can be approximately converted into human years by multiplying by 4 and adding 16. Complete the table to represent the relationship between cat age and human years.
Answer:
Step-by-step explanation:
If the age of a cat is represented by 'x' and human years by 'y', relation between the age of cat and human years will be,
y = 4x + 16 [multiplying cat's age by 4 and by adding 16]
Now from the given table,
If x = 2,
y = 4×2 + 16
= 24
If y = 3,
y = 4×3 + 16
= 28
If x = 4,
y = 4×4 + 16
= 32
If x = 5,
y = 5×4 + 16
= 36
If x = 6,
y = 6×4 + 16
= 40
Cat age 2 3 4 5 6
Human years 24 28 32 36 40

simplify 13 =a(2)+b(2)+c
Answer:
13=2a+2b+c
Step-by-step explanation:
The product of terms 2 and the associated variable, is the result of double the variable. For example, a(2)= 2a.
The equation (specifically the expression and its terms on the right) cannot be simplified furthermore as there are no like terms that are able to be combined.

Find the slope of the line graphed below.
Answer:
-3/5
Step-by-step explanation:
The phone company NextFell has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of money per minute used on the phone. If a customer uses 260 minutes, the monthly cost will be $114. If the customer uses 640 minutes, the monthly cost will be $247.
A) Find an equation in the form y= mx+b, where x is the number of monthly minutes used y is the total monthly cost of the NextFell plan.
Answer: _____
B) Use your equation to find the total monthly cost if 949 minutes are used.
Answer: If 949 minutes are used, the total cost will be _____ dollars.
Answer:
Explained below.
Step-by-step explanation:
(A)
Use two-point form to determine the equation for the total monthly cost of the NextFell plan.
[tex](y-y_{1})=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\cdot (x -x_{1})\\\\(y-247)=\frac{247-114}{640-260}\cdot (x-640)\\\\(y-247)=0.35x-224\\\\y=0.35x+23[/tex]
(B)
Compute the total monthly cost if 949 minutes are used as follows:
[tex]y=0.35x+23\\\\=(0.35\times 949)+23\\\\=355.15[/tex]
Thus. the total monthly cost if 949 minutes are used is $355.15.
