Answer:
108 degrees
36 degrees
72 degrees
trapezoid
Step-by-step explanation:
Answer: y= -x-5
Step 1: Determine which equation to change
Since we will be using the substitution method, we will need to substitute y from the bottom equation with information from the top equation. This will be the equation we change.
Step 2: Change the equation
Let’s rewrite the equation we will be working with.
3x+3y= -15
Our goal will be to get y alone on the left side. To start, let’s subtract 3x from both sides, leaving only 3y on the left side.
3x+3y= -15
3y= -3x-15
Now we need to get y completely alone by eliminating the coefficient of 3. Let’s do this by dividing each term by 3.
3y= -3x-15
y= -x-5

Step-by-step explanation:
24% = 156
1% = 24%/24 = 156/24 = 6.5
100% = 1%×100 = 6.5×100 = 650
so, 650 students were surveyed.
