Answer:
25
Step-by-step explanation:
When you substitute x for 3, the new equation would be ; 3(3)(2) - 2(3) + 13
using order of operations from left to right, you would start by multiplying
3(3)(2) and 3(3) is 9, and 9(2) is 18. The next step is to multiply 2 and 3 which is 6. Once you have both groups of numbers simplified, you can plug them back in : 18 - 6 + 13 ; 18 - 6 is 12, and 12 + 13 is 25, so the answer is 25.
Answer:
11) 140/8 = 17.5
12) 38/3 = 12.667
13) 114/9 = 12.667
14) 7/2 = 3.5
15) 14/9 = 1.556
Step-by-step explanation:
To solve each problem you need to multiply the numerator by the whole number:
11) 7*20 = 140
12) 2*19 = 38
13) 6*19 = 114
14) 1*7 = 7
15) 7*2 = 14
Next, you put these numbers back into their corresponding numerators and divide:
11) 140/8 = 17.5 (You can simplify this fraction to 70/4 if needed)
12) 38/3 = 12.667 (This answer is rounded to the thousandths place)
13) 114/9 = 12.667 (This answer is rounded thousandsths place)
14) 7/2 = 3.5
15) 14/9 = 1.556 (This answer is rounded thousandths place)
**These are the improper fractions written as mixed ones** :
11) 17 1/2
12) 12 2/3
13) 12 2/3
14) 3 1/2
15) 1 5/9
I hope this helps!
Answer: 39.4784
Step-by-step explanation:
The equation for area of a circle is (3.14)r^2.
Just plug in the given radius (4) into the equation and solve.
We can set this geometric sequence up as so:
y = 50,000(0.90)^(x - 1)
The value of the car is represented by y, and the year is represented by x.
