Let's think of .4 as 0.4
How many times will 0.4 go into 25?
0.016 times.
Answer:
( , - )
Step-by-step explanation:
8x + 4y = 7 → (1)
6x - 8y = 41 → (2)
multiplying (1) by 2 and adding to (2) will eliminate y
16x + 8y = 14 → (3)
add (2) and (3) term by term to eliminate y
22x + 0 = 55
22x = 55 ( divide both sides by 22 )
x = =
substitute this value into either of the 2 equations and solve for y
substituting into (1)
8( ) + 4y = 7
20 + 4y = 7 ( subtract 20 from both sides )
4y = - 13 ( divide both sides by 4 )
y = -
solution is ( , - )
Answer:
A
Step-by-step explanation:
12 / tan 42 = 13.32......
12 / sin 27 = 26.43....
26.43² - 12² = 552.24....
square root of 552.24... = 23.5
23.5 - 13.3 = 10.2
