There are 309 dimes... think of it like this
5(d + 7) + 10d = 4670
5d + 35 + 10d = 4670
15d + 35 = 4670 then you take that and subtract on both sides cancelling out the 35
15d = 4670 - 35
15d = 4635
d = 4635/15
d = 309
Answer:
x = 43
Step-by-step explanation:
Since it says at the bottom that the sum of angle measures is 360° that means that you can dd up all the angles and it will equal 360.
<u>Set up an equation</u>
(3x) + (2x) + (x + 12) + (2x + 4) = 360
<em>Then add them all together.</em>
5x + (3x + 16) = 360
8x + 16 = 360
<em>Subtract 16 from both sides to get 8x alone.</em>
8x = 344
<em>Then divide both sides by 8 to get x</em>
How fast the distance between them decrease is 16mph
<h3>How to calculate the speed of an object?</h3>
Given the following parameters
Speed of the hiker = 6mph
If is it 3/11 the rate of a cyclist, then the rate of the cyclist will be:
6 = 3x/11
3x = 66
x = 22mph
Distance between them = 22 - 6
Distance between them = 16mph
Hence how fast the distance between them decreases is 16mph

Answer:
Between 15.5 and 16.5 ounces
Step-by-step explanation:
If the distribution is bell-shaped it follows a normal distribution.
In a normal distribution you except the 95% of the values between +-2 standard deviation from the mean.
lower limit = 16 - 2 * 0.25 = 15.5
upper limit = 16 + 2 * 0.25 = 16.5
