Answer:
y=770-55x --- given
y - 770 = 770 - 55x - 770 ----subtraction property of equality
y = -55x + 770 ---Simplification
y-770/-55 = -55x/-55 --- Division property of equality
-y-770/55=x---Simplification
Step-by-step explanation:
the nearest hundred spot is 700 for the number. when rounding for hundreds, you use the 2nd digit number. Example, if a proablem asks to round 521 to the nearest hundred it would be 500. Another rule to remember is that anything 5 and above you round up (ex: 589 would round up to 600). Anything below 5 you would round down (ex: 234 would round down to 200). goinf back to the problem, the answer should be 7,700
Answer:
Answer ::+-6
Step-by-step explanation:
x:3=12:x
or, x/3 = 12/x
Doing cross multiplication,
x^2=36
Putting sqare root on both sides,
x= sqrt. 36
x= +- 6
Therefore x=+-6.
-2-3x=3+1x
-2-3=1x+3x
-5=4x
x=-1.25
