Answer:
y=-4/23
im not sure i didn't check (might be wrong)
Step-by-step explanation:
4x - 5y = -28
-3x - 2y = 10
then make x the same
So
12x-15y=-84
-12x-8y=80
then its left with
-23y=-4
y=-4/23
find x by entering y into -3x - 2y = 10 and solving
The hypothesis (If the sidewalks are wet) of this conditional statement is true, but the conclusion (it has been raining) is false.
<h3>What is a conditional statement?</h3>
A conditional statement can be defined as a type of statement that can be written to have both a hypothesis and conclusion. This ultimately implies that, it typically has the form "if P then Q."
Where:
P and Q represent sentences.
<h3>What is a hypothesis?</h3>
In Science, a hypothesis is primarily considered to be a tentative or an educated guess and it can be defined as a testable explanation for an observation or a specific experimentation (scientific) problem, especially by using the "if . . . then . . . because" format..
The hypothesis (If the sidewalks are wet) of this conditional statement is true, but the conclusion (it has been raining) is false. Also, this can be proven with this counterexample "If the sidewalks are wet, then it is cause of an erosion/irrigation."

Answer:
x = 4 and y = 8
Step-by-step explanation:
This is a special right triangle with angle measures 90-60-30 degrees
The side lengths are like the following :
The side length that sees 90 degrees is represented with a
The side length that sees 60 degrees is represented with a
The side length that sees 30 degrees is represented with 2a
now, the angle measure that sees 60 degrees is given as 4 so we understand that a is = 4 that's how we find the value of x and y
