Ok let's translate question mathematically.
Let x be first number
y be second number
z be third number
So this question says
y = 2x
z = 2+5x
y+z = 37
So we need so solve those equations.
Use first and second into third:
(2x) + (2+5x) = 37
7x + 2 = 37
7x = 35
x = 5
Now plug x value into first and second equation:
y = 2(5)
y = 10
z = 2+5(5)
z = 2+25
z = 27
So the answer is
First number is 5, second number is 10, and third number is 27
Answer: 60.875
Step-by-step explanation:
57+59+60+60+61+61+64+65= 487
then 487/8= 60.875
Answer:
The integers are -3 and -4.
Step-by-step explanation:
Two consecutive integers are an integer and the one just greater or just less than the4 first one, such as 5 and 6, or -8 and -9.
If the smaller integer is x, then the next greater integer is x + 1.
x + 1 = 4x + 13
-3x = 12
x = -4
x + 1 = -3
Answer: The integers are -3 and -4.
Check:
Smaller integer: -4
Larger integer: -3
4 times smaller integer = 4 * (-4) = -16
13 greater than 4 times smaller = -16 + 13 = -3 = greater integer
-3 and -4 is the correct answer.
Answer:
5cm
Step-by-step explanation:
Given parameters:
Volume = 45cm³
Radius = 3cm
Unknown:
Height of the cone = ?
Solution:
Volume of cone is given as ;
V = r² h
r is the radius
h is the height
45 = x 3² x h
45 = 3π x h
h = = 4.77cm
5cm is the closest answer choice
