When the Sun's energy moves through space, it reaches Earth's atmosphere and finally the surface. This radiant solar energy warms the atmosphere and becomes heat energy. This heatenergy is transferred throughout the planet's systems in three ways: by radiation, conduction, and convection.
Answer:
x = 15
Step-by-step explanation:
Given that,
The length of the base of an isosceles triangle is x.
The length of a leg is 3x-4.
Perimeter, P = 97
An isosceles triangle has one base. The perimeter of a triangle is given by :
97=x+3x-4+3x-4
97 = 7x-8
97+8=7x
105 = 7x
x = 15
So, the value of x is 15.
Answer:
6
Step-by-step explanation:
Luckily for us, the expression only contains a variable y, so we can disregard the values for variables x and w.
Note, that y = 1.
With that in mind, let's evaluate the expression by plugging the value of y into the expression.
11y - 5 = ?
11(1) - 5 = ?
11 - 5 = ?
6 = ?
Hence, our expression evaluated to 6 when y = 1.
Cheers.
