-2x - 6 = 2 - 4x - (x - 1)
solve
Answer:
Step-by-step explanation:
-2x - 6 = 2 - 4x - x + 1
-2x - 6 = 3 - 5x
3x - 6 = 3
3x = 9
x = 3
x + 7 = 9

early says that m ×(-1) is always equal to m ÷(-1) for all rational values of m. is he correct
Answer:
The equation are true.
Step-by-step explanation:
Given
[tex]m * (-1) = m / (-1)[/tex]
Required
True or false?
We solve this question from right to left:
[tex]m * (-1) = m / (-1)[/tex]
Express / as *
[tex]m * (-1) = m * 1/(-1)[/tex]
[tex]m * (-1) = m * (-1)[/tex]
The expression on both sides of the equation are true.
In the diagram below of parallelogram ROCK, m angle is 70 degrees and m angle ROS is 65 what is the value of x
Answer:
135
Step-by-step explanation:
The measure of the angle KSO is 135°
What is a parallelogram?A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal.
Given that, In the diagram below of parallelogram ROCK, m angle is 70 degrees and m angle ROS is 65
We know that, opposite angles of a parallelogram are equal,
Therefore, ∠ ORK = 70°
In triangle, SRO, ∠ ORK and ∠ ROS are interior angles, and ∠ KSO is an exterior angle,
We know, The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.
Therefore, ∠ KSO = ∠ ORK + ∠ ROS
∠ KSO = 135°
Hence, The measure of the angle KSO is 135°

what is the proof by reduction to absurdity?
Answer:
Reductio ad absurdum is a Latin phrase that means "reduction to the absurd". The phrase describes a kind of indirect proof. It's proof by contradiction and is a common form of argument. It shows that a statement is true because its denial leads to a contradiction or a false or absurd result.
Suppose y varies directly as x. If x = 24 when y = 8, then what is the constant of variation
Direct variation is represented by the formula [tex]\frac{y}{x} = k[/tex]
where k is the constant of variation.
So here, since we know that x = 24 and y = 8,
the constant of variation must be equal to 8/24.
if we write 8/24 in lowest terms, we have 1/3.
So 1/3 = k.
Can someone help with this problem (time sensitive)
Answer:
∠D = 52º
∠E = 32º
∠F = 96º
Step-by-step explanation:
the sum of interior angles of a triangle equals 180º
so: (x + 20) + (3x) + 32 = 180
3x + x + 20 + 32 = 180 combine like terms
4x + 52 = 180 subtract 52 from both sides
4x = 128 divide both sides by 4
x = 32
plug x into each angle measure to get them:
∠D = (32) + 20 = 52º
∠E = 32º (given)
∠F = 3(32) = 96º

Answer:
20%
Step-by-step explanation:
If it was 0.3 it would be 30% or if it was .35 it would be 35%.
0.3 is another way of writing 0.30 but since it's just a zero, you don't really have to write 30.

Eva is going to the amusement park, where she has to pay a set price of admission and another price for tickets to go on each of the rides. The total amount of money Eva will spend is given by the equation y=26+1.5x. , where y represents the total amount of money, in dollars and cents, and represents the number of rides Eva goes on . What could the number 1.5 represent in the equation ?
Answer:
B. The change in the total amount if money for every one additional ride she goes on
Step-by-step explanation:
Given,
y = 26 + 1.5x, where,
y = total amount of money Eva will spend
x = number of rides Eva rides on
Thus,
Set price of admission into the amusement park = $26
Price per ride = $1.5
Therefore, the 1.5 I'm the equation can be said to be "the change in the total amount if money for every one additional ride she goes on".
