Answer:
-5
Step-by-step explanation:
-5(1-5x)+5(-8x-2) = -4x-8x
-5+25x-40x-10 = -12x
-15-15x = -12x
-15 = -12x + 15x
-15 = 3x
x = -15 ÷ 3
∴x = -5

what is the value of x in 36/45 = x/5
Answer:
x = 4
Step-by-step explanation:
Cancel common factor of 9,
(x/5)=(4/5)
Multiply both sides by 5,
(5x/5)=(20/5)
Simplify to get x = 4
Evaluate
5-(x - 2) for x = - 1
5 - ( x - 2 )
substitute -
5 - ( -1 -2 )
step 2 - now solvefirst solve the bracket
5 - ( - 1 - 2 )
therefore,
5 - ( - 3 )
solve
= 8
so the answer is 8hope that helps !

When x is added to its square, the total is 30. Fond the value of x.
(With solution please)
Answer:
[tex]x=\frac{30}{(1+x)}[/tex]
Step-by-step explanation:
step one:
This is a word problem, we need to translate is it to mathematical terms before we solve
"When x is added to its square, the total is 30"
step two:
[tex]x+x^2=30[/tex]
[tex]x+x^2=30\\\\x(1+x)=30\\\\[/tex]
step three:
divide both sides by 1+x we have the value of x as
[tex]x=\frac{30}{(1+x)}[/tex]

Question 5 Rocko paid $12.50 for 25 game tickets. Louisa paid $17.50 for 35 game tickets. What is the constant of proportionality? Express your answer in decimal form.
Answer: k = $0.50
Step-by-step explanation:
The data that we have is:
Rocko paid: $12.50 for 25 tickets.
Louisa paid: $17.50 for 35 tickets.
Now, the question asks to find the constant of proportionality.
A proportional relation can be written as:
y = k*x
where k is the constant, and in this case, y is the price and x the number of tickets bought.
Then replacing with the values above, we have:
$12.50 = k*25
then:
k = $12.50/25 = $0.50
And the other data:
$17.50 = k*35
K = $17.50/35 = $0.50
So we have the same k in both cases, this means that the constant of proportionality is k = $0.50
In a rectangle, the sides have measurements of 2x + 1 and 3x - 5 units Find an expression for the area of the rectangle, in square units.
Answer:
[tex] (6 {x}^{2} - 7x - 5) \: {units}^{2} [/tex]
Step-by-step explanation:
Area of rectangle = Product of sides
[tex] = (2x + 1) \times (3x - 5) \\ = 2x(3x - 5) + 1(3x - 5) \\ = 6 {x}^{2} - 10x + 3x - 5 \\ area \: of \: rectangle \: \\ = (6 {x}^{2} - 7x - 5) \: {units}^{2} [/tex]

Which is the product of 4^4(4^-7)(4)?
Answer:
1/16 or 0.0625
Step-by-step explanation:
we can take 4 outside the parentheses and we would get 4^(4-7+1)=4^(-2)= 1/(4^2)=1/16=0.0625.
Answer:
0.0625
Step-by-step explanation:
[tex]4^{4}[/tex] ( [tex]4^{-7}[/tex] ) (4)
First lets deal with 4^4 which is 256 (4 * 4 * 4 * 4)
256 ( [tex]4^{-7}[/tex] ) (4 )
Then 4^-7 which is [tex]\frac{1}{16384}[/tex] ( this is because when 4^-7 is simplified it becomes 1/4^7 which is 1/16384.
256 ( [tex]\frac{1}{16384}[/tex]) (4)
256 * [tex]\frac{1}{16384}[/tex] * 4= 0.0625

How do you write the converse of a conditional? How do you Write the contrapositive of a conditional?
Answer:
Converse- If q, then p. Contrapositive- If not p, then not q
Step-by-step explanation:
Let's say your conditional is if an angle is 90 degrees then it is a right angle.
Then the converse is, if an angle is a right angle then it is 90 degrees.
Finally, the contrapositive is if an angle is not 90 degrees then it is not a right angle.
Point R is on line segment QS. Given QS = 16 and QR = 9, determine the length RS.
Answer:
The length RS = 7
Step-by-step explanation:
Here, we are interested in determining the length of RS
Let’s have the line segment arranged as follows;
Q R S
where QR = 9 and QS = 16
From the arrangement, we can deduce that;
QS = QR + RS
Thus;
RS = QS - QR
RS = 16 -9
RS = 7

Which number line shows the inequality n < -3?
Answer: like he dark line represents all the numbers that satisfy x≤2 . If we pick any number on the dark line and plug it in for x, the inequality will be true. The following graph represents the inequality x < 2 . Note that the open circle on 2 shows that 2 is not a solution to x < 2 .
Step-by-step explanation:
Find the circumference of the circle. Round your answer to two decimal places, if necessary.
Use the Circumference of a Circle Formula:
C = 2πr
or
C = (Diameter)*π (since diameter = 2*radius)
In this case, the diameter is 44 miles
So the circumference is:
C = 44*π = 138.23 miles
