Solve S=a/(1-r) for r S = a/(1-r) Multiply both sides by 1-r S*(1-r) = [(1-r)*a]/(1-r) Simplify S*(1-r) = a Multiply terms on the left. S - S*r = a Subtract S from both sides. S-S*r - S = a - S Simplify -S*r = a - S Multiply both
Can you please check my work? You have helped other students I know. Thank you:) Multiply -7(2a2 -4) = -14a2 + 28 Multiply 0.5(a + b -5) = 0.5a + 0.5b - 2.5 Factor bx - by + bz = b(x - y + z) Combine like terms (simplify) 12x + 4
my post is still on this page as algebra, could someone elaborate on what bobpursley tried to help me with. See your original post. I am guessing you are referring to your question 5)Simplify:(5x-4)^2 and your answer= 25x^2 - 16
how do i do x2+12x+32 x2+12x = 14x+32 subtract 14x from each side 14x=32 divide by 2 7x=16 x=16/7, which is 2 and 2/7 ok maybe you typed that question wrong? is it x^2 + 12x + 32 ? if it is then the solution is: (x+8)(x+4) because
Solve. x/9-1/7=26/63 STEP 1: The LCM is _________ To clear denominators, multiply each side of the equation by the LCM. _______/1 (x/9-1/7)=__________/1 multiply 26/63. STEP 2: Use the Distributive Property. _____/1 multiply x/9 -
I having a hard time with this word problem: A backyard has dimensions 4 and 2/5 yards by 2 and 4/5 yards. What is the area of the backyard in square yards (yd^2)? Do I mulitiply and then simplify? Yes, you do multiply and then
Can you tell me how you arrive at the answer to this question: if you multiply meby2, I become a number greater than 20and less than 40. If you multiply me by 6 I end in 8. If you multiply me by4,I end in 2.
How would I multiply these expression? 6(h-4) -3(x+8) -10(-a+5) PLease and thank-You Multiply the coefficient (outside the parentheses) by each term inside the parentheses. For example, 6(h-4) = 6h - 24 You do the others do you
