Let h be the height. Then:
1/2 (22h)=7500
22h=15000
h=15000/22=681.8181 yds
K is the midpoint of JL...so JK=KL=7
JL=(JK + KL)>>>>>>whole part axiom
or,4x=2×JK>>>>>>>{JK=KL➡JK+KL=JK+JK}
or,4x=2×7
or,x=14/4=7/2
[ x=7/2 ] [KL=JK=7] and [JL=4x=(4×7)/2=14]
In order to make 119$ he would need to work 7 hours
-140 = 28 + 4(5y-2)
Use distributive property:
-140 = 28 + 20y -8
Combine like terms:
-140 = 20 + 20y
Subtract 20 from both sides:
-160 = 20y
Divide both sides by 20:
y = -160 / 20
y = -8
The answer is B) -8
