Just did this assignment.
Answer/Step-by-step explanation:
Given:
m<EFH = (5x + 1)°
m<HFG = 62°
m<EFG = (18x + 11)°
Required:
1. Value of x
2. m<EFH
3. m<EFG
SOLUTION:
1. Value of x
m<EFH + m<HFG = m<EFG (angle addition postulate)
(5x + 1) + 62 = (18x + 11)
Solve for x using this equation
5x + 1 + 62 = 18x + 11
5x + 63 = 18x + 11
Subtract 18x from both sides
5x + 63 - 18x = 18x + 11 - 18x
-13x + 63 = 11
Subtract 63 from both sides
-13x + 63 - 63 = 11 - 63
-13x = -52
Divide both sides by -13
-13x/-13 = -52/-13
x = 4
2. m<EFH = 5x + 1
Plug in the value of x
m<EFH = 5(4) + 1 = 20 + 1 = 21°
3. m<EFG = 18x + 11
m<EFG = 18(4) + 11 = 72 + 11 = 83°
Answer:
E. 5
Step-by-step explanation:
GH + HI = 7
GH = 2
2 + HI = 7
HI = 5
Answer: E. 5
Answer:
Step-by-step explanation:
(7/10 + -3)/(2 + 1/4)
(7/10 - 30/10)/(8/4 + 1/4)
(-23/10)/(9/4)
-2.3/2.25
-0.46/0.45 or -1.02 approximately
$6400 is the amount you will have in 15 years
