M<ADC = 112, m<BDC = 12x-3, m<ADB = 6x+7
m<BDC = ?

m<BDC = m<ADC - m<ADB
12x - 3 = 112 -(6x+7)
12x - 3 = 112 -6x - 7
12x + 6x = 105 + 3
18x = 108
x = 108/18
x = 6

m<BDC = 12x-3
m<BDC = 12(6) - 3
m<BDC = 72 - 3
m<BDC = 69

answer m<BDC = 69

A car driver charges 2$ for first 1/4 mile and for every next 1/4th mile he charges 0.3$ for 6 miles distance.how much would be
Oduvanchick [21]

Answer:

$8.90

Step-by-step explanation:

$2 for the 1/4 mile. That leaves 5 3/4 more miles until 6 miles. He charges 30 cents for each additional 1/4 miles, and there are twenty-three 1/4ths in 5 3/4. So, 23*30=690, which is basically $6.90 because it's 690 cents.

$6.90+$2=$8.90

Round to the nearest given place.<br> 1.80431<br><br> thousandths
rodikova [14]
In order to round a number to the nearest thousandths, we have to check the number in the ten thousandths place:
1- If the number in the ten thousandths is less than 5, then the thousandths number will remain the same and all numbers after it will be converted to zeroes.
2- If the number in the ten thousandths is equal to or greater than 5, then the thousandths number will be incremented by 1 and all numbers after it will be converted to zeroes.

Applying this to the given number: 
<span>1.80431
</span>The number in the ten thousandths position is 3 which is less than 5.
Therefore, rounding <span>1.80431 to the nearest thousandths will be:
</span>1.80400 which is equivalent to 1.804
