Answer:
A. No
Step-by-step explanation:
the point (2, 9) means x = 2 and y = 9.
plug this into the equation:
9 = -5 * 2 + 1
9 = -10 + 1
9 = -9
Not true, this is not a solution
Yeah, they're equal.
8 * 3 = 24 and 8 * 4 = 32
so 24x+32 = 24x+32
Answer:
10/24 and 15/36, more answers possible
Step-by-step explanation:
if you multiply both the numerator and denominator by the same number, it will always be equivalent to 5/12, as you can simplify it back to that fraction.
5/12, multiply both by two, and you have 10/24
5/12, multiply both by three, and you have 15/36
Answer:
S = √A
Step-by-step explanation:
Given that;
A = S²
Finding S implies making S the subject of the expression.
To do this;
A = S²
Take the square root of both sides of the expression;
√A = √S²
The square-root of the square of S = S;
S = √A
Answer: 55% of the students passed the math test
Step-by-step explanation: The fraction 
represents the number of students who passed the math test out of all the students that took the test.
To find out what percent of the students that took the math test passed, we can turn the fraction into a percent.
To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. So to write as a percent, we need to find a fraction that is equivalent to with a 100 in the denominator. We can do this by setting up a proportion.
Now, we can use cross products to find the missing value.
4,400 = 80n
÷80 ÷80
55 = n
Therefore, 55% of the students that took the math test passed it. This should make sense because 40/80 would be half and 44 students is only a little over 50%.
