Answer:
8 in, 8 in and 20 in
Step-by-step explanation:
Let the equal sides of the isosceles triangle be x, then
The base = 2.5x
Sum the 3 sides and equate to the perimeter of 36
x + x + 2.5x = 36
4.5x = 36 ( divide both sides by 4.5 )
x = 8
Thus the 2 equal legs = 8 in
base = 2.5x = 2.5 × 8 = 20 in
The average in January is -36°
The average in July is 17° warmer
So add 17 to -36
The average in July is -19°C
Answer:
Slope =
Step-by-step explanation:
(-9, -8) & (-15 , -16)
Slope =
You first multiply the outside exponents into the numbers in the parentheses.
When you have an exponent being multiplied directly to another exponent, you multiply the exponents together.
For example(because I am a bad explainer):
When you divide an exponent by an exponent, you subtract the exponents
For example:
When you have a negative exponent, you move it to the other side of the fraction to make the exponent positive
For example:
You can think of it like this if you want:
Now multiply the outside exponents into the exponents in the parentheses
Divide 27 and 9
Your answer is
3x + y = 9
3x - 5y = 15
15x + 5y = 45
<span>3x - 5y = 15
</span>
18x = 60
x = 10/3 or 3.33.
Plug that into the equation and Y is equal to -1. Hope this helped. Once again the answer is (10/3, -1).
