Answer:
Step-by-step explanation:
Split the words at "and" and solve one piece at a time. (when a function has "or equal to", use the ones with the line under 
) Let x be the unknown value
"less than or equal to 87"
"greater than or equal to 83"
Put them together by putting x in the middle. Don't forget to make the signs face the right way:
Done.
3 x 4(hours) = 12
60 - 12 = 48
At 4am the temperature was 48 degrees
Let's solve your equation step-by-step.
4(2x+8)=10x+2−2x+30
Step 1: Simplify both sides of the equation.
4(2x+8)=10x+2−2x+30
(4)(2x)+(4)(8)=10x+2+−2x+30(Distribute)
8x+32=10x+2+−2x+30
8x+32=(10x+−2x)+(2+30)(Combine Like Terms)
8x+32=8x+32
8x+32=8x+32
Step 2: Subtract 8x from both sides.
8x+32−8x=8x+32−8x
32=32
Step 3: Subtract 32 from both sides.
32−32=32−32
0=0
Answer:
All real numbers are solutions.
Answer:
0,4,8,12,16
Step-by-step explanation:
so for the value of x- just substitute it into the equation
so -2
8+4(-2)
8-8=0
