Answer:
-8x + 146
Step-by-step explanation:
Step 1: Write out expression
3(58 - 6) - 2(4x + 5)
Step 2: Parenthesis
3(52) - 2(4x + 5)
Step 3: Multiply
156 - 2(4x + 5)
Step 4: Distribute
156 - 8x - 10
Step 5: Combine like terms (constants)
-8x + 146
True
<span>There is some disagreement whether parallelograms, which have two pairs of parallel sides, should be regarded as trapezoids. Some define a trapezoid as a quadrilateral having only one pair of parallel sides (the exclusive definition), thereby excluding parallelograms.</span>
Answer: They are parallel
Step-by-step explanation:
If two lines are parallel , then they must have the same slope and if two lines are perpendicular , the product of their slope must be -1.
To check this , we must calculate the slope of the two lines given.
Slope = 
from the first point
= 2
= 1
= 5
= -1
substituting the values
slope 1 = 1 - 2 / -3 - 5
slope1 = -1 / -8
slope 1 = 1/8
Using the same format to calculate the slope of the second line
= -2
= 0
= -1
= 15
slope 2 = 0 - (-2) / 15 - (-1)
slope 2 = 2/16
slope 2 = 1/8
Since slope 1 = slope 2 , this implies that the lines are parallel
C
4/8 equals 1/2 the rest are 1/2 but 12/36 is 1/3
As the question says that Tory knows for $5 he will get 3.45 euros.
Now for the euro trip he needs to know the rate of conversion or the rate of euros per dollar.
To find the rate of conversion we need to use unitary method.
As we know that at the given rate he gets,
3.45 euros for $5
or the other way around
euros
Now, using the unitary method we get,
euro
Therefore, at the given rate we can see that for each dollar Tory would get 0.69 euro.
