Answer:
x = 145°
Step-by-step explanation:
We know that y = 98°, so we can find ∠DBC:
180°-y = ∠DBC
180°-98° = 82°
We also know that z = 63°, therefore we can apply <u>exterior angle of triangles</u> to find x.
∠DBC + z = x
82°+63° = x
x = 145°
Answer: 24
Step-by-step explanation:
The ratio of sandcastles to kites was 3 to 5 so if 15 kites were spotted that meant that the 5 was multiplied by 3 so then we multiply the 3 by 3. Now there are 9 sandcastles and 15 kites so now we add 9 to 15 to figure out how many items were seen in all. Nine added to 15 equals 24 which means that 24 items were seen in total.
The scientific notation is:
<u><em>1.0 x 10^-11</em></u>
Answer:
f(x) = 15000 - 150x
Step-by-step explanation:
Given that:
Initial Amount owed = $15000
Amount payed towards debt per month = $150
Total amount owed as a function of month(x) after each payment :
F(x) = Initial amount owed - (amount paid per month * number of month)
Let number of month = x
f(x) = 15000 - 150x
Hence, the function ;
f(x) = 15000 - 150x represents the total amount owed after each payment.
3x-2=2x-7
We simplify the equation to the form, which is simple to understand
3x-2=2x-7
We move all terms containing x to the left and all other terms to the right.
+3x-2x=-7+2
We simplify left and right side of the equation.
+1x=-5
We divide both sides of the equation by 1 to get x.
x=-5
