The answer would be km for the distance.
Answer:
(2,-3)
Step-by-step explanation:
have to multiply (-3) to the second equation to get -3x + 15y = 51 then you add both equations .the 3 is remove (postive and negative cancels out )
2y+15y= 17y
0-51+-51
divide both sides by 17 y
-51/17= -3
then you plug -3 into the first equation and get
x= 2
y=-3
Answer:
The answer would be 2,240
Step-by-step explanation:
Answer:
C: 31
Step-by-step explanation:
15 x 15 = 225
16 x 16 = 256
256 - 225 = 31
According to the rule of BODMAS multiplication goes first.
B - brackets
O - operations
D - division
M - multiplication
A - addition
S - subtraction
to answer the question, 4 ^ x goes first. which equals 4x. the new equation would be:
4x + 3 = 18
now you have to move +3 over the equals sign which becomes negative (-):
4x = 18 - 3
4x = 15
next you have to get the x to be alone, move the 4 over the equals sign. 15 is now divided by 4:
x = 15/4
x = 3.75
