What they’re asking for is a ratio:
Car’s weight:force required
You need 110 pounds to lift a 2500 pound car
2500:110
We can see each side is divisible by 10.
250:11
So the ratio is 250:11.
In scientific notation the numeric value is the same only the power of the x10 multiplier changes
<span>In mathematics, an inequality is a
relation that holds between two values when they are different (see
also: equality). The notation a ≠ b means that a is not equal to b.</span>
10(6+2z)+8 distribute 10
60+20z+8 add like terms
68+20z is answer since you can’t simplify anything further
