3x+5=245

Helpppppppppppp

Answers

Answer 1
Answer:

Answer:

X = 80

Step-by-step explanation:

Subtract "5" from both sides,

3x + 5 - 5 = 245 - 5

Simplify,

3x = 240

Divide both sides by "3",

3x/3 = 240/3

X = 80


Hope this helps :-)
Answer 2
Answer: 3x + 5 = 245
Subtract 5 from both sides to get x alone on one side
3x = 246
Now divide by 3 on both sides
x = 82

Given that the equation of a straight line is -4x 2y=16, what is the value of the gradient and of the y-intercept: Gradient: Y-intercept:

Answers

gradient is
if you have
ax+by=c
gradient (aka slope)=a/b

we have
-4x+2y=16
a=-4
b=2
gradient=-4/2=-2

y intercept is when the line crosses the y axis, also that is when x=0 so set x=0 and solve for y
-4(0)+2y=16
0+2y=16
2y=16
divide 2
x=8
y intercept=8



gradient=-2
y intercept=8 (y=8 aka point (0,8))

If 3 dogs are going to share 32 ounces of canned dog food equally by weight how many ounces should each dog get? I NEED THIS ASAP! Everyone says 32 divided by 3 but thats like... Crazy weird.

Answers

Maybe I'm not understanding, but I would say 32 ounces divided by 3 gives an equal amount of food for each dog. So i would just solve 32/3. Hope this helps... sorry if it didn't!
