Fred, a skycap at the airport, is paid
$5.15 per hour. During an 8-hour
shift, he earned $195.00 in tips. What
were his estimated total earnings for
a 40-hour week?
Answer:
401 a week
Step-by-step explanation: Fred earns $5.15 dollars plus a tip of $195 if he works for 40 hours the equation would be x=ab+c X is the week, A is the money per hour, B is the amount of hours and C is the tip X= 5.15(40)+195 5.15 times 40 is 206 then 206+195 is 401 which is your answer
An item was marked down 64% from its original price,x . The amount discounted was $30. Which equation can be used to find the original price
Answer:
OP = discount amount × 100 / discount %
Step-by-step explanation:
if I understand this correctly, the actual sale price was 36% (100-64) of the originally marked price.
original price (OP) = 100%
64% of OP = 30
1% of OP = 30/64
OP (100%) = 100 × 30/64
this could be simplified to 100 × 15/32, but this hinders is finding the global formula :
OP = discount amount × 100 / discount %

Answer:
x = 15
Step-by-step explanation:
If A parallel to B then ∠ 2 and ∠ 4 are same- side interior angles and sum to 180° , then
2x + 10 + 4x + 80 = 180 , that is
6x + 90 = 180 ( subtract 90 from both sides )
6x = 90 ( divide both sides by 6 )
x = 15

Answer:
x = 4
Step-by-step explanation:
The segment inside the triangle is an angle bisector and divides the opposite side into segments that are proportional to the other two sides , that is
[tex]\frac{15}{20}[/tex] = [tex]\frac{x+2}{14-(x+2)}[/tex]
[tex]\frac{3}{4}[/tex] = [tex]\frac{x+2}{14-x-2}[/tex] = [tex]\frac{x+2}{12-x}[/tex] ( cross- multiply )
4(x + 2) = 3(12 - x) ← distribute parenthesis on both sides )
4x + 8 = 36 - 3x ( add 3x to both sides )
7x + 8 = 36 ( subtract 8 from both sides )
7x = 28 ( divide both sides by 7 )
x = 4
4x - 10 + 5x = 71 solve the equation and enter the value of x below
Answer:
x = 9
Step-by-step explanation:
First, combine like terms. Like terms are terms with the same variable as well as the same amount of said variables:
4x - 10 + 5x = 71
(4x + 5x) - 10 = 71
9x - 10 = 71
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Do the opposite of PEMDAS.
PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& Roots)
Multiplications
Divisions
Additions
Subtractions
~
First, add 10 to both sides of the equation:
9x - 10 (+10) = 71 (+10)
9x = 71 + 10
9x = 81
Next, isolate the variable x by dividing 9 from both sides of the equation:
(9x)/9 = (81)/9
x = 81/9 = 9
x = 9 is your answer.

Can someone help me with this math homework please!
Step-by-step explanation:
these are almost the simplest possible problems to get you a little bit familiar with the use of this line of thinking and to use these methods.
come on ! are you really not understanding this ?
I think you are not trying to learn and get better, you try to get others doing your work for you.
these problems are so simple that stating them here costs you more time than just solving them.
remember fractions ?
remember the problems to find the smallest common denominator for a list of fractions ?
the first question is exactly that.
what is the smallest common denominator of 3/4, 1/3 and 1/2 ?
because that is the number you need to multiply both sides to eliminate all fractions.
so, what is the smallest number that can be split by 4, 3 and 2 ?
is it 2 ? no, 4 and 3 can't do that.
is it 3 ? no, 2 and 4 can't do that.
...
is it 6 ? no, 4 can't do that.
...
is it 8 ? no, 3 can't do that.
...
is it 12 ? yeah ! all 3 can do that.
here a little tip : you start by multiplying all involved numbers, and then work your way back by eliminating some factors shared by some of the numbers.
here it would be
2×3×4 = 24
but 12 is sufficient, because 2 and 4 share another common factor of 2. so, we can divide 24 by 2 and get 12.
"isolate the variable" means having it only on one side of the equation.
so, what do you think ?
subtracting any constants does not change anything for "j".
from all the offered options only the subtraction of 1.1j eliminates j from one side.
the runners save.
you only need to translate the words into the corresponding mathematical symbols.
runner 1 has $112 already saved.
that is our starting value for this runner.
so, 112 + ...
received a $45 gift card. so, $45 are added.
so, 112 + 45 + ...
saves $25 each month (m). so, whatever the number of m is, there will be $25×m added to the account.
so, 112 + 45 + 25m
we know already, it is the second option.
but for training purposes let's look at runner 2 too :
he starts with $50 already saved.
so, 50 + ...
saves $60 each month (m). same principle as above.
so, 50 + 60m
if we want to know, when (after how many months) both runners will have the same amount of money, we simply need to say both equations are equal and solve for m.
-3x + 1 + 10x = x + 4
how do we solve this ?
by bringing all x to one side and contract them into one expression. and try to bring all constants to the other side and contact them too. and then do the reverse operation of the x expression (like a division for a multiplication).
1 + 7x = x + 4
1 + 6x = 4
6x = 3
x = 3/6 = 1/2
hurray, it is the first option !

Step-by-step explanation:
which inequality represents all values of x for which the quotient below is defined? √15(x-1) ÷ √2^2
Answer:
Option D: x ≥ 1.
Step-by-step explanation:
Here we have the quotient:
[tex]\frac{\sqrt{15*(x - 1)} }{\sqrt{2*x^2} }[/tex]
Here we have two restrictions for the domain.
first, the denominator can never be zero, so x must be different than zero.
Second, the arguments of the square roots can not be negative.
The one in the denominator is always positive because we have the square of x.
So let's look at the values of x, such that:
15*(x - 1) ≥ 0
(x - 1) ≥ 0
x ≥ 1
Note that when x ≥ 1, we are also removing the problem in the denominator, then we can conclude that the fraction is defined when:
x ≥ 1.
The correct option is D

Which compound inequality is equivalent to | ax -b | > C for all real numbers a, b, and c, where c>0?
Hello,
Answer D
ax-b < -c or ax-b >c
If ax-b >0 then |ax-b| = ax-b ==> ax-b > c
if ax-b <0 then |ax-b|=-(ax-b) > c ==> ax-b <-c
The equivalent compoud inequality is (d) ax - b > c or ax - b < -c
How to determine the compound inequality?The absolute value expression is given as:
| ax -b | > c
Given that c > 0, then it means that:
| ax -b | > 0
So, we have the following inequalities from | ax -b | > c
ax - b > cax - b < -cHence, the equivalent compoud inequality is (d) ax - b > c or ax - b < -c

The perimeter of a rectangular swimming pool is 56 meters. The width is 4 meters less than the length. What is the width of the swimming pool? 4 meters 4 meters 8 meters 8 meters 12 meters 12 meters 24 meters
Answer:
Length = 16 meters
Width = 12 meters
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Let
length = x
Width = (x - 4) meters
Perimeter of the rectangular pool = 56 meters
Perimeter of a rectangle = 2(length + width)
56 = 2{x + (x - 4)}
56 = 2(x + x - 4)
56 = 2(2x - 4)
56 = 4x - 8
56 + 8 = 4x
64 = 4x
x = 64/4
x = 16
length = x = 16 meters
Width = (x - 4) meters
= 16 - 4
= 12 meters

Explanation: ok the left triangle is 9 and 27 and the right triangle is 3 and 9
The way you find this is saying what can you multiple the smaller numbers to get the big numbers, so 9 x 3 = 27 and 3 x 3 = 9 which is the bigger triangles area. The easiest way to do this in the future is take the biggest numbers and divide them by the denominated in your answer choices because if you took 27 and 9 / 3 you would get the numbers on the right side triangle. Good luck in the future :)

does the point (-4, 2) lie inside or outside or on the circle x^2 + y^2 = 25?
Step-by-step explanation:
The solution and answer are well written in the Pic above.
Given equation of the Circle is ,
[tex]\sf\implies x^2 + y^2 = 25 [/tex]
And we need to tell that whether the point (-4,2) lies inside or outside the circle. On converting the equation into Standard form and determinimg the centre of the circle as ,
[tex]\sf\implies (x-0)^2 +( y-0)^2 = 5 ^2[/tex]
Here we can say that ,
• Radius = 5 units
• Centre = (0,0)
Finding distance between the two points :-
[tex]\sf\implies Distance = \sqrt{ (0+4)^2+(2-0)^2} \\\\\sf\implies Distance = \sqrt{ 16 + 4 } \\\\\sf\implies Distance =\sqrt{20}\\\\\sf\implies\red{ Distance = 4.47 }[/tex]
Here we can see that the distance of point from centre is less than the radius.
Hence the point lies within the circle .
