Step-by-step explanation:
There is no equation which have no solution.
What linear equation has no solution?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
1. 1/(x - 31) = 5
1 = 5 · (x - 31)
1 = 5 · x - 155
5 · x = 156
x = 31.2
2. 12 · x - 11 = 0
12 · x = 11
x = 11/12
3. 15 - 3 · x = - 8
3 · x = 23
x = 23/3
4. - x + 91 = 0
x = 91

Ronna answered 18 of the 20 questions on her second math test correctly. On the first test, she had answered only 15 of 20 questions correctly. What was the percent increase in her score from her first test to the second test? A. 15% B. 35% C. 75% D. 90
Answer:
A: 15%
Step-by-step explanation:
First test:
15 ÷ 20 = 0.75
0.75 * 100 = 75%
Second Test:
18 ÷ 20 = 0.9
0.9 * 100 = 90%
90% - 75% = 15%
which of the following relations is a function ?
Answer:
Step-by-step explanation:
The relation that is a function is c
the answer is not d
Answer:
Answer c: 1000
Step-by-step explanation:
Set f(x) = 2 log x - 6 = 0 as a first step in finding the zero or zeros.
2 log x - 6 = 0 becomes log x - 3 = 0 after dividing all three terms by 2.
Then log x = 3, and because "log x" has base 10, the value of x is 10^3, or 1000.

Put the steps in the correct order to show how a budget is made.
First Step
T1 Total up spending
11 Reduce expenses in flexible categories to save or increase savings
Ti Calculate income
Ti Determine if spending is below income
11 Categorize expenses
Final Step
Answer:
The correct answer is: Calculate income, Total up spending, Categorize expenses, Determine if spending is below income, and Reduce expenses in flexible categories to save or increase savings. When making a budget, it's first necessary to figure out how much money comes in and goes out, and then to compare expenses to income to make cuts if necessary.

10. Rhonda Harmon's credit card statement showed an $839.78 balance. Since then, she has made a $110.50 payment
and purchases totaling $143.75. What is Rhonda's new balance?
NEED HELP PLSS
Answer:
585.53 new balance
$839.78 - 110.50 - 143.75
Answer: 585.53
Step-by-step explanation:
839.78 - 110.50 = 729.28
729.28 - 143.75 = 585.53
At 50, Brian sets up an IRA, where he plans to deposit $12,000 at the end of each year until age 75. Find the amount of the annuity if he invests in a stock fund that yields 4% compounded annually.
Answer: the amount of the annuity is $501000
Step-by-step explanation:
We would apply the future value which is expressed as
FV = C × [{(1 + r)^n - 1}/r]
Where
C represents the yearly payments.
FV represents the amount of money
in your account at the end of 25 years.
r represents the annual rate.
n represents number of years or period.
From the information given,
r = 4% = 4/100 = 0.04
C = $12000
n = 75 - 50 = 25
Therefore,
FV = 12000 × [{(1 + 0.04)^25 - 1}/0.04]
FV = 12000 × [{2.67 - 1}/0.04]
FV = 12000 × 41.75
FV = $501000
what is th rate equivalent to an annual rate of 20% with monthly capitalization
Answer:
about 21.9%
Step-by-step explanation:
The effective annual multiplier is ...
(1 +r/n)^n = (1 +0.20/12)^12 ≈ 1.21939
The rate equivalent is 1 less than this:
1.21939 -1 = 0.21939 = 21.939%

Jillian calculates that see will take 95 minutes to run 7 miles. She runs the distance in 80 minutes. What is Jillian’s percent error?
Answer:
Kawaii, the problem is the comparison with the calculated time for Jillian and the actual time for Jillian to run the 7 miles.
%error=(calculated value - experiemental value)/calculated * 100%
%error=(95-80)/95*100%=15/95 *100% = 15.79 ≈ 16% error
Note: 16% error is the approximate error because the numbers have 2 significant figures stated in the problem.

Which geometry includes a triangle that has angle measures of 45°, 61°, and 70°? Euclidean geometry hyperbolic geometry elliptical geometry spherical geometry
Answer: Hyperbolic geometry
Step-by-step explanation:
Hyperbolic triangle is a non - Euclidean triangle in which the sum of the angles of the triangle is not up to 180 degrees. That is, less than 180 degree.
Euclidean geometry is the normal geometry that is being taught in school in which the sum of the angles of its triangle equals 180 degrees
While spherical geometry is a non euclidean geometry with sum of the angles of its triangle greater than 180 degrees.
Therefore, the triangle that has angle measures of 45°, 61°, and 70° is a non - Euclidean geometry which is hyperbolic geometry.
Answer:
hyperbolic geometry

O D. x = B(k-c)
SUBMIT
Helpp plzzzz
Answer:
x = (k-c)/8
Step-by-step explanation:
8x+c= k
Subtract c from each side
8x+c-c= k-c
8x = k-c
Divide each side by 8
8x/8 = (k-c)/8
x = (k-c)/8
Renee can see a 25 square foot quilt in 16 hours. Genera can sew the same size quilt in 12 hours. How long would it take them to see the quilt together?
28 hours because they are too long from each other
Answer:
Approximately 6.86 hours.
Step-by-step explanation:
Renee sews at a rate of 1.5625 sq ft an hour. Found using square feet divided by hours.
Genera sews at a rate of 2.084 sq ft an hour. Found using square feet divided by hours.
To find how fast they can sew the quilt together, we must add their sewing speeds together: 1.5626 + 2.084 = 3.64583333.
Using this equation we can divide a 25 sq ft quilt by their speed of 3.64583333 to get approximately 6.86 hours.
The answer is approximate because we used rounded decimals.
Select the ordered pairs that satisfy the equation y=1/5x.
Check all that apply.

Can someone help me for brainllest ITS TIMED AND IM FREAKING OUT
Answer:
1.
If two angles are supplementary, their sum is 180 degrees.
Check: 10 + 170 = 180
=> Maryam's claim is correct
If two angles are complementary, their sum is 90 degrees.
Check: 81 + 9 = 90
=> Ailia's claim is correct
2.
As the definition:
Vertical angles have sides that form two pairs of opposite rays.
Adjacent angles have a common side and don't overlap.
=> As provided pair of angles, they are adjacent pair of angles.
=> Ahmed's statement is wrong, Saalem's statement is correct.
Hope this helps!
