You need to get rid of -6 by adding 6, you also need to add 6 to 18.
4x = 24
Now you need to get rid of the 4 attached to the variable, you do this by dividing 4 since it is multiplying, also dividing 4 and 24
x = 6
So the value of x is 6
Hope this helps! :)
To solve this, let us first imagine a smaller triangle
created by the head of Jim (A), the top of the lamp post (B), and somewhere on
the body of the lamp post which is directly perpendicular to the head of Jim
(C).
CB = 16 – 6 = 10 ft
AC = 4 ft
Calculate for angle B using tan function:
tan B = AC / CB
B = tan^-1 (4 / 10)
B = 21.8°
Now imagine a bigger triangle created by the tip of
shadow (D), the top of the lamp post (B), and the base of the lamp post (E).
BE = 16 ft
B = 21.8°
We can calculate for DE using tan function:
tan B = DE / BE
(16 ft) tan 21.8 = DE
DE = 6.4 ft
Since Jim is 4ft away from the base of the lamp post,
therefore the length of the shadow is:
6.4 ft – 4 ft
= 2.4 ft
Therefore the length of Jim’s shadow is 2.4 ft long
Answer:
L = 2*6 - 8 = 12 - 8 = 4
W = 6*6 + 1 = 36 + 1 = 37
That's the math.
Step-by-step explanation:
P = 2*(L + W)
L = 2x - 8
W= 6x + 1
P = 82
2(2x - 8 + 6x+1) = 82 Combine terms in the brackets.
2(8x - 7) = 82 Divide both sides by 2
2(8x - 7)/2 = 82/2
8x - 7 = 41 Add 7 to both sides
8x - 7 +7 = 41+7
8x = 48 Divide by 8
8x/8 = 48/8
x = 6
Answer:
about 11.50
Step-by-step explanation:
6 / 5.70 = 1.05
