Answer:
3*5^6
Step-by-step explanation:
72 is 266.666666667% of 27
The temperature would be -10 degrees
Answer:
22.07 ft & 9.32 ft
Step-by-step explanation:
by sines rule :
20/sin 65° = r/sin 90° = y/sin 25°
r = 20×sin 90°/sin 65° = 20/0.9063
= 22.07 ft
y = 20×sin 25°/sin 65° =
20× 0.4226/0.9063
= 9.32 ft
The solution to the given system of equation is (25/7, 6/7)
<h3>System of equation</h3>
Given the system of equation expressed as:
x= - 4y+7 ........... 1
-2y+3x=9 ...........2
Substitute the equation 1 into 2 into have:
-2y + 3(-4y+7) = 9
-2y + 3(-4y) + 3(7) = 9
-2y - 12y + 21 = 9
Collect the like terms
-14y = 9- 21
-14y = -12
y = 6/7
Substitute y = 6/7 into equation 1;
x =-4y + 7
x = -4(6/7) + 7
x= -24/7 + 7
x = -24+49/7
x = 25/7
Hence the solution to the given system of equation is (25/7, 6/7)
