Answer:
x = 75
Step-by-step explanation:
Triangle BDH
The angle must add to 180 degrees
36+ 39 + DHB = 180
75 + DHB = 180
DBH = 180-75
DHB = 105
DBH + x = 180 since it is a straight line
105+ x = 180
x = 75

Answer: 5. AE
6. 6cm
7. 20 in
8. Angle DCF
Step-by-step explanation:
The estimated sum of the numbers fifty-eight (58) and twenty-nine (29) is equal to ninety (90).
<h3>What is the difference between a regular sum and an estimated sum?</h3>
In an estimated sum, the numbers are rounded; on the other hand, in a regular sum, the numbers are not changed.
<h3>What is the estimated sum of 58 and 29?</h3>
1. Round the numbers:
- 58 = 60 as this number is nearest to 60 than to 58.
- 29= 30 because of the same reason explained above.
2. Add the rounded numbers:

Answer:
- $5 bills x 5, $1 bills x 10, quarters x 16, dimes x 9
Step-by-step explanation:
- $5 bills = x, total = 5x
- $1 bills = 2x, total = x
- Quarters = 3x + 1, total = 0.25(3x + 1)
- Dimes = 3x + 1 - 7= 3x - 6, total = 0.1(3x - 6)
<u>Equation below as the sum, solve for x:</u>
- 5x + 2x + 0.25(3x + 1) + 0.1(3x - 6) = 39.9
- 7x + 0.75x + 0.25 + 0.3x - 0.6 = 39.9
- 8.05x - 0.35 = 39.9
- 8.05x = 40.25
- x = 40.25/8.05
- x = 5
<u>Number of each bill and coin:</u>
- $5 bills = 5
- $1 bills = 2*5 = 10
- Quarters = 3*5 + 1 = 16
- Dimes = 3*5 - 6 = 9
