Answer:

18

Step-by-step explanation:

x  + y = 10 (1)\\ x  - y = 6(2) \:   \\ 2y = 4  \:  \: ie \: y = 2 \\ x + y = 10 \\ x = 10 - 2 \\ x = 8 \\ x3 - y3 = (8 \times 3) - (2 \times 3) \\  = 24 - 6 \\  = 18

Answer = 18


If you mean x times 3 and y times 3, x= 8 and y = 2 so (8*3)-(2*3)=18

A 10-foot ladder leans against a wall with its foot braced 3 feet from wallÍs base. How far up the wall does the ladder reach?
iren2701 [21]
The answer is √91 feet (which is the same as 9.54 feet).

Imagine this as a right triangle. A length of the foot is actually a hypotenuse (c). The distance from wall's base to the ladder foot is one of the sides of the triangle (let it be a).
So, using the Pythagorean theorem:
c² = a² + b²
It is given:
c = 10 feet
a = 3 feet
b = ?
     c² = a² + b²
⇒ 10² = 3² + b²
    100 = 9 + b²
    b² = 100 - 9 = 91
    ⇒ b = √b² = √91 ≈ 9.54 feet

A local pizzeria sold 65 pizzas yesterday. Suppose the actual number of pizzas sold today was 60. Describe
Rudik [331]
We need to find the difference first. 65 - 60 = 5. Now we must find what percent 5 is of 65. It is 7,7%. The number decreased, and so it is a 7,7% decrease.
