Answer:
Simplifying
12x + 2y = 18
Solving
12x + 2y = 18
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
12x + 2y + -2y = 18 + -2y
Combine like terms: 2y + -2y = 0
12x + 0 = 18 + -2y
12x = 18 + -2y
Divide each side by '12'.
x = 1.5 + -0.1666666667y
Simplifying
x = 1.5 + -0.1666666667y
Answer:
(i) 8.5 × 10^-12
(ii) 9.42 × 10^-12
(iii) 602 × 10^15
(iv) 8.37 × 10^-9
(v) 3.186 × 10^10
Step-by-step explanation:
(i) 0.0000000000085
= 0.0000000000085 × 10^12/10^12
= 8.5/10^12
<u>= 8.5</u><u> </u><u>×</u><u> </u><u>10^-12</u>
(ii) 0.00000000000942
= 0.00000000000942 × 10^12/10^12
= 9.42/10^12
<u>= 9.42</u><u> </u><u>×</u><u> 10^-12</u>
(iii) 6020000000000000
<u>= 602 </u><u>×</u><u> </u><u>10^15</u>
(iv) 0.00000000837
= 0.00000000837 × 10^9/10^9
= 8.37/10^9
<u>= 8.37</u><u> </u><u>×</u><u> </u><u>10^-9</u>
(v) 31860000000
<u>= 3.186 </u><u>×</u><u> 10^10</u>

Answer:
150 one point throws, 165 two points throws and 110 three points throws
Step-by-step explanation:
Let x be the number of free (one point) throws.
The number of free throws Sarah made was 15 less than the number of two-point field goals she made. If y is the number of two points throws, then

so the number of two points throws 
The number of two-point field goals that Sarah made was 55 less than double the number of three-point field goals she made. If z is the number of three points throws, then

so the number of three points throws 
The total score is 810 points, so
