Answer: The price of the torch is 2 and 2/2.5 is 80% or 8/10th of the total price.
Step-by-step explanation:
x is the price of the battery
x + 1.50 is the price of the torch
x + (x + 1.50) is 2.50
x + (x + 1.50) = 2.50
2x = 2.50 - 1.50
2x = 1
x = 1/2
x = 0.50
The price of the torch is 2 and 2/2.5 is 80% or 8/10th of the total price.
Answer:
Step-by-step explanation:
We need to find the error first.
We can do this by subtracting, to find the difference
2.4-1.9 = 0.5
the difference, or error, is 0.5
Now we find a percentage that describes how much more 2.4 is than 1.9
We can create an equation to solve this
2.4 = 1.9 Times x
Now we need to find the value of x
x= 1.2632
now we double check
1.9 Times 1.2632 = 2.4
Now we round to a whole number
1.2632 = 1
To convert a number to a percentage, you need to bring the number over a decimal point.
so 1 becomes .1, or 10 percent
Answer: 
a = 2 and b = 3
==================================================
Explanation:
Let's expand out 
to get the following:
The x term here is 2ax
Compare this to the x term of 
and we see that
--------------
The constant term of 
is the 
portion since it doesn't have the variable x attached to it.
Compare this with the 7 of which is also the constant.
Equate the two items, plug in a = 2 and solve for b.
Therefore,
37÷6
=6.1666666667
- 0.1666666667
=6
Answer:
∠Z and ∠W are supplementary
Step-by-step explanation:
In the diagram given showing a special trapezoid, WX and ZY are two opposite sides that are parallel to each other.
Thus, consecutive angles would be supplementary.
Therefore, the only correct option that is true is:
∠Z and ∠W are supplementary.
The test options are incorrect as consecutive angles are not complementary and they are not in themselves congruent to each other.
