Answer:
Ok, so the discount is given in a percentage, in this case 10%. The sale price is going to reflect 10% of the original price minus the discount, so...
Sale $ = original$ - original $ x .10
If we use some algebra, we can reorganize the equation to solve for the original price...
Sale $ = original$ - original $ x .10
Sale $ = original$ (1 - .10)
Sale $ = original$ x .90
original$ = sale$/.90
So now we can plug in our values
original price = 50/.90
original price = 55.55555 = $55.55 to the nearest nickel

A fisherman can row upstream at 2mph and downstream at 8mph. He started rowing upstream till he got tired and the rowed downstream to his starting point. How far did the fisherman row if the entire trip took 2 hours
Answer:
The fisherman row 6.4 miles total.
Step-by-step explanation:
Let the distance from his starting point to the point he turn around is "d" miles.
Given upstream speed is 2 mph and downstream speed is 8 mph.
We now that time = distance /speed
So the time required to row "d "miles upstream = d/2 hours
The time required to row "d" miles downstream = d/8 hours.
As the entire trip took 2 hours so the equation will be :
d/2 +d/8 = 2
( 4d + d ) /8 = 2
5d = 16
d = 16/ 5 = 3.2 miles
So the fisherman rowed a total of ( 3.2 x 2 ) miles = 6.4 miles.
(HELP) My Subaru Crosstrek can travel 107 miles on 3 gallons of gas. How many miles can my
car travel on a full tank of gas? A full tank of gas is 14 gallons.
9514 1404 393
Answer:
499 1/3 miles
Step-by-step explanation:
Let m represent the number of miles the car can travel on 14 gallons. We assume distance is proportional to gas usage, so ...
m/14 = 107/3
Multiplying by 14, we have ...
m = 14(107/3) = 1498/3 = 499 1/3
The car can travel 499 1/3 miles on a full tank of gas.

The production cost to make 10 shirts is modeled by the expression Syntax error from line 1 column 49 to line 1 column 73. Unexpected 'mathsize'. where y represents the number of meters of fabric needed to make the shirts. Which expression represents the production cost for one shirt?
Answer:
the second one, B
Step-by-step explanation:
This is because in both numbers the decimal was moved back one.
0.18y+55 is the represents the production cost for one shirt.
What is Expression?Expression is a combination of numbers, variables and operators.
Given that production cost to make 10 shirts is modeled by the expression 1.8y+55.
The variable y represents the number of meters of fabric needed to make the shirts.
We need to find the expression represents the production cost for one shirt.
As there are 10 shirts so divide 1.8 with 10
we get 0.18.
And the value remains constant as it is a constant which does not change.
Hence, 0.18y+55 is the expression represents the production cost for one shirt.

Answer:
-2 tiles
Step-by-step explanation:
In each figure, 5 tiles are added.
Subtract 5 from how many tiles are in Figure 2 (8 tiles) & you get 3.
3 is how many tiles are in Figure 1, meaning you need to subtract 5 again to see how many are in Figure 0! 3-5 = -2.

5x is greater than or equal to -25
The product of 5 and a number is at least –25
we convert the given statement into inequality
product means multiplication
Let x be the unknown number
product of 5 and a number is 5x
5x is at least -25
For word at most we use <=
for word at least we use >=
So the expression becomes 5x <= -25

No, 5/8 cannot make the equation [tex]\frac{8}{15}-x=\frac{3}{7}[/tex] to be true
The given fractional equation is:
[tex]\frac{8}{15}-x=\frac{3}{7}[/tex]
To calculate the fraction that will make the equation [tex]\frac{8}{15}-x=\frac{3}{7}[/tex], solve for x in the given equation:
[tex]\frac{8}{15}-x=\frac{3}{7}[/tex]
Collect like terms
[tex]x=\frac{8}{15}-\frac{3}{7}[/tex]
Simplify the resulting fraction as follows:
[tex]x=\frac{56-45}{105} \\\\x=\frac{11}{105}[/tex]
Therefore, the missing fraction that will make the equation [tex]\frac{8}{15}-x=\frac{3}{7}[/tex] true is 11/05
We can conclude that 5/8 cannot make the equation [tex]\frac{8}{15}-x=\frac{3}{7}[/tex] to be true

Since [tex]\frac{5}{8} \neq\frac{11}{105}[/tex], hence [tex]\frac{5}{8}[/tex] will not make the equation true.
Equations and expression
Given the equation
[tex]\frac{8}{15}-a=\frac{3}{7}[/tex]a is the fraction that will make the equation to be equal
Subtract [tex]\frac{8}{15}[/tex] from both sides;
[tex]\frac{8}{15}-a-\frac{8}{15} =\frac{3}{7}-\frac{8}{15}\\-a= \frac{3}{7}-\frac{8}{15}\\-a=\frac{3(15)-7(8)}{105} \\-a=\frac{45-56}{105}\\-a=\frac{-11}{105}[/tex]
Multiply both sides by a negative sign to have:
[tex]-(-a)=-(-\frac{11}{105} )\\a=\frac{11}{105}[/tex]
Since [tex]\frac{5}{8} \neq\frac{11}{105}[/tex], hence [tex]\frac{5}{8}[/tex] will not make the equation true.

Answer:
23a) x=-y+9/2
23b) x=1/2 y+3/2
Step-by-step explanation:
23a:
Let's solve for x.
2x+2y=9
Step 1: Add -2y to both sides.
2x+2y+−2y=9+−2y
2x=−2y+9
Step 2: Divide both sides by 2.
2x/2 = -2y+9/2
x = -y+9/2
23b:
Let's solve for x.
2x−y=3
Step 1: Add y to both sides.
2x−y+y=3+y
2x=y+3
Step 2: Divide both sides by 2.
2x/2=y+3/2
x = 1/2 y+3/2

Chrystelle's mother is 1 2/3ft taller than Chrystelle. If
Chrystelle is 3 1/2 ft tall, how tall is her mother?
Answer:
4 5/6 feet.
Step-by-step explanation:
The least common multiple for 2 and 3 is 6, so if we change the denominators to 6, we get Chrystelle's height as 3 3/6, and her mother is 1 4/6 ft taller than her.
3 3/6 + 1 4/6= ?
(Written as an Improper fraction)
21/6 + 10/6 = 31/6
31/6 = 4 5/6.
I hope this helps!
Answer:
first make it so the denominator is the same on bothers sides. a common denominator for both is 6 so
Chrystelle mom: 1 2/3 taller. multiply the fraction by 2/2 so 1 4/6
chrystelle: 3 1/2 feet tall. multiply the fraction by 3/3 so 3 3/6
now just add to figure out so
3 3/6 + 1 4/6 = 4 7/6 which simplifies down to 5 1/6
so chrystelles mom is 5 1/6 feet tall

can someone pls help me i need to know what is 2x - 1 = 7
Answer:
The solution for x would be 4.
Step-by-step explanation:
2x - 1 = 7
The value of x is unknown, but you do know that you are multiplying 2 by x. So, if you rewrite the equation as 7+1=2x, you know that 8=2x. If you then divide both sides by 2, you're left with 4=x which would mean that the variable x has a solution of 4

Step-by-step explanation:
Solution,
Given,
base = 4
perpendicular = 6
hypotenuse = ?
Now,
By the formula of Pythagoras Theorem,
h^2 = p^2 + b^2
h^2 = 6^2+4^2
h^2 = 36+16
h = sqrt ( 52 )
h = 7.21
Therefore, the value of x (hypotenuse) is 7.21 .
Answer:
x= 7.21///no
Step-by-step explanation:
4^2 + 6^2 = 52
take the square root which equals 7.21
///
Pythagorean triples consist of perfect squares, like 2^2 is for the side that is equal to 4, 6 is not a perfect square.

3b + 9 =23
6c + 9 = 23
Determine whether each statement about the equations is true or false
Answer:
1. False
2. True
3. True
4. False
Step-by-step explanation:
a + 9 = 23
a = 14
3b + 9 = 23
3b = 14
b = 14/3
6c + 9 = 23
6c = 14
c = 14/6 = 7/3
Statement 1: 3a = 14 x 3 = 42, which is not equal to b.
Statement 2: 7/3 is less than 14.
Statement 3: 2c = 7/3 x 2 = 14/3 = b.
Statement 4: 6c = 14 = 3b, so the value of 6c is not greater than 3b. It is just equal to.
