Multiply 42.50 by 3.5 then add 60.00 to your answer
First you want to collect the like terms, 2a=45 , then divide both sides of the equation by 2 which is a=2/5 , or a=0.4
Woah that's a hard one, my answer is A. but I'm not certain
B=9
Explanation:
Multiply everything by 3 to get rid of the fraction. The new equation is 2b +15 = 60 -3b. Next, add three b to 2b and subtract 15 from 60. New equation is 5b = 45. Divide both sides by 5. B = 9.
Answer:
x=6, x= -5
Step-by-step explanation:
Factor the equation
x^2 - x - 30 = 0 ----> (x-6)(x+5)=0
Next find the solution by setting those in the paranthesis equal to zero.
x-6=0 ----> x= 6
x+5=0 ----> x= -5
