Answer: (i) 4x - 40 = 76
(ii) 29 questions
Step-by-step explanation:
Let the total number of questions be x.
Since he received 4 points for every correct answer and he got 10 answers wrong , this means he lost 40 points , the equation thus become
4x - 40 = 76
To find the value of x , add 40 to both sides
4x = 116
divide through by 4
x = 29
Therefore , there are 29 questions on his math test
Answer:
A.
Step-by-step explanation:
100 is equal to $1.
100/5=20
Rise over run is another term for slope, with we can use to derive a linear equation.
The term rise over run in technical terms is the change of y over the change of x.
To find the rise over run, subtract the y terms and divide that by the x terms.

You can use this to derive a linear equation as earlier mentioned by plugging in given points.
For example, a line passes through (3,4) with a rise over run of 3.




So therefore the y intercept is -5, and the equation is 
Answer:
16x - 2 + y
Step-by-step explanation:
(48x - 6 + 3y)/3 = 48x/3 - 6/3 + 3y/3 = 16x - 2 + y
Lines TW and YX are parallel because the angels are congruent (-:
