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
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:)

Consider the initial value problem:
2tyâ²=8y, y(1)=â2. 2tyâ²=8y, y(1)=â2.
Required:
a. Find the value of the constant C and the exponent r so that y=Ct^r is the solution of this initial value problem.
b. Determine the largest interval of the form a < t < b on which the existence and uniqueness theorem for first order linear differential equations guarantees the existence of a unique solution.
c. What is the actual interval of existence for the solution (from part a)?
Answer:
Following are the solution to the given point:
Step-by-step explanation:
In point a:
[tex]\to 2ty'=8y\to \frac{1}{y} dy = 4 \frac{1}{t} dt\\\\\to \int \frac{1}{y} dy = 4 \int \frac{1}{t} dt \\\\\to \log y = 4 \log t + \log C\\\\\to \log y = \log ct^4\\\\\to y=ct^4 \\\\\to y(-2)=16 \\\\\to 16= c(-2)^4\\\\\to 16= 16c\\\\\to c= \frac{16}{16}\\\\\to c=1\\\\\to r=4[/tex]
In point b:
[tex]\to 2ty' = 8y \\\\\to y'- \frac{4}{t} y=0 \\\\here \ p(t) = \frac{1}{t}[/tex] it's a discontinuous point at t=0, and the largest internal containing -2 since [tex]y=(-2) = 16 \ is\ (-\infty, 0)[/tex]
In point c:
[tex](-\infty,0 ) \cup (0, \infty)[/tex]
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!
Cheers, I hope you can understand it well!

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
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!

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

Answer: It would be B 9/50
Step-by-step explanation: if you take 3/7 and x it by 0.1 you get 0.04285714285 and then if you divide that by 5/21 you get 0.18 which equals 9/50 as a fraction
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
what is the value of x in teh equation 1/5x-2/3y=30, when y=15
Answer:
x=200Step-by-step explanation:
Given the equation
[tex]\frac{1}{5}x-\frac{2}{3}y=30[/tex]
putting y=15
[tex]\frac{1}{5}x-\frac{2}{3}\left(15\right)=30[/tex]
[tex]\frac{1}{5}x-10=30[/tex]
add 10 to both sides
[tex]\frac{1}{5}x-10+10=30+10[/tex]
[tex]\frac{1}{5}x=40[/tex]
[tex]x=200[/tex]
Therefore, the value of x:

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:

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

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°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.
