Answer:
As an equation, (we'll use x as the variable), that word problem is 3x+7=31.
To solve we'd subtract 7 from both sides to isolate 3x, which gives us 3x=24. Now, to isolate x(unknown number) we would divide both sides by 3. When you divide both sides by 3, you'd get x=8.

Is this rational or irrational
Answer:
irrational
Step-by-step explanation:
√15 is not a rational number it's a irrational number
:-))
Answer:
Irrational
Step-by-step explanation:
Rational numbers are those that can be written in the form a/b where a and b are both integers with no common factors.
sqrt15 cannot be written in that form, therefore it is irrational.
What is an angle that is supplementary KFA?
Given:
A diagram.
To find:
An angle that is supplementary to ∠KFA.
Solution:
Supplementary angle: Two angles are called supplementary angles if they are lie on the same side of a straight line and their sum is 180 degrees.
From the given diagram, it is clear that ∠KFA lies on the intersection of lines HL and IK.
∠KFA and ∠DFA lie on the same side of a straight line IK.
∠KFA and ∠KFL lie on the same side of a straight line HL.
So, ∠DFA and ∠KFL are the angles supplementary to ∠KFA.
We need only one supplementary angle. So, we write either ∠DFA or ∠KFL.
Therefore, an angle that is supplementary to ∠KFA is ∠KFL.

The value of 3(2)ˣ for x = -1 is 3/2
What is simplification?In mathematics, simply or simplification is reducing the expression/fraction/problem to a simpler form. It makes the problem easy with calculations and solving.
Given is a function, f(x) = 3(2)ˣ
When x = -1
f(-1) = 3(2)⁻¹
f(-1) = 3x2⁻¹
f(-1) = 3x1/2
f(-1) = 3/2
Hence, The value of 3(2)ˣ for x = -1 is 3/2

EFGH is an isosceles trapezoid. If EH=4x-27 and FG=x+9, find the value of x.
PLEASE HELP ASAP!
Answer:
If EFGH is an isosceles trapezoid,
if
EH=4x-27+
FG=x%2B9+
EG=3y%2B19
FH=11y-21
then EH=FG and EG=FH
set up equations:
4x-27=x%2B9 .......solve for x
4x-x=27%2B9
3x=36
x=36%2F3
3y%2B19=11y-21.......solve for y
11%2B19=11y-3y
30=8y
y=30%2F8
y=15%2F4
y=3.75
so,x=12 and y=3.75
you can also check the length of equal sides and equal diagonals:
EH=4%2A12-27+=21
FG=12%2B9+=21
EG=3%283.75%29%2B19=30.25
FH=11%283.75%29-21=30.25x=12

A 24-foot ladder leaning against a wall makes a 30 ° angle with the ground . How high up on the building is the top of the ladder ?
HELP ASAP
Answer:
[tex]12\:\mathrm{ft}[/tex]
Step-by-step explanation:
When the ladder is leaning against the wall, a 30-60-90 triangle is formed. The ladder acts as a 24-foot hypotenuse. Because the height is facing the [tex]30^{\circ}[/tex] angle, the height is half the hypotenuse (30-60-90 rules). If you forget the side rules for a 30-60-90 triangle, simply use basic trig on the right triangle:
[tex]\sin 30^{\circ}=\frac{h}{24},\\h=24\sin 30^{\circ},\\h=24\cdot \frac{1}{2},\\h=\fbox{$12\:\mathrm{ft}$}[/tex].

Mark has less than 20.00 to spend on the cost of dinner
And remember the little $4308 pizza-mistake? How many weeks would you have
to work to pay for this mistake with the $13 bounced check? Round up to the next
whole week.
weeks
It required 332 weeks to pay the whole amount.
Given that,
Amount to repay = $4308
Amount to be repaid in a week = $13
The number of weeks that will be consumed is to be determined.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Let the number of weeks be x,
By arithmetic operations
13x = 4308
x = 4308 / 13
x = 331.34
x ≈332 weeks
Thus, It required 332 weeks to pay the whole amount.
