Answer:
Answer is B
Step-by-step explanation: divide 120, 240, and 360 by each possible answer. then from the answers that dont leave a remainder, divide it by 160 and 320 and choose the answer that gives you a remainder for both
Apple: £20
Banana: £60
I believe this is the answer because between the two problems there is a difference of £60. So I saw three apples were gone from the next so 60 divided by 3 is 20. Then we need to find the banana price. 20 x 7 = 140. 200 - 140 is 60. So the banana is 60 and the apples are 20.
Answer:
Step-by-step explanation:
Evaluate all the arithmetic first, and then remember absolute value equations have two possible ways to go (+ and -).
You can see how I split them on the 3rd line, later demonstrating how the 2nd one is invalid.
Therefore, the solution is
The answer is (C) 19 because you would first subtract 231 from both sides and you would get -7a=-133 the you would divide -7 from both sides and get a=19.
Answer:
Step-by-step explanation:
x + 3 y = 1 ----------------(I)
-3x - 3y = -15 -------------(II)
Add the equations and y will be eliminated and we can find the value of x
(I) x + 3y = 1
(II) <u>-3x -3y = - 15</u> {Now add}
-2x = - 14
x = -14/-2
x = 7
Plugin x =7 in equation (I)
7 + 3y = 1
3y = 1 - 7
3y = -6
y = -6/3
y = -2
