Answer:
I think it's 15 18 and 5 or 14,12
Answer:
the sum of two rational number is minus 4 by know if one of them is 13 by 6 them find the other
Step-by-step explanation:
let the second rational no. be x
then a/q,
13/6 + x = -4/9
x = -4/9 - 13/6
x = (-16 - 78)/36
x = - 94/36 or -47/18
x = -2.61111
Answer:
b. g(x) = 12x+10
c. x = 9/2
Step-by-step explanation:
b. g(2x+1)=6x+4
g(2x+1) = 6(2x+1)+4
g(2x+1) = 12x+6+4
g(2x+1) = 12x+10
g(x) = 12x+10
c. g(x) = 64
12x+10 = 64
12x = 54
x = 54/12
x = 9/2

Answer: Part A = Age, Part B = 154 - 0.7a, Part C = 140 beats per minute (BPM)
Step-by-step explanation: The question states "...in beats per minute, <u>depends on a person's age</u> and can be represented..." and the variable is a, so a is age. To rewrite an expression, you need to multiply the number outside the parentheses with the terms inside the parentheses. In this case 0.7 * 220, which is 154 and 0.7 * a which is 0.7a. So the expression rewritten is 154- 0.7a. In order to solve question C you need to plug in the variable. So 0.7(220 - 20) or 154 - 0.7 * 20, whichever is easier. After solving, your answer will be 140 beats per minute.
