Answer: 7
−4 ∗ x + 7∗ y = 125 = 2 ∗ x + 5y = 7
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:
53 Meters.
Step-by-step explanation:
34*34 + 41*41 = 2837.
1156 + 1681 = 2837.
The square root of 2837 would be your answer.
34*34 + 41*41 = 53.26349 * 53.26349
a*a + b*b = c*c.
a² + b² = c².
Answer:
24 + 8i
Step-by-step explanation:
t = 4
u = 6 + 2i
t x u
= 4 ( 6 + 2i )
= 24 + 8i
