Answer:
Conversion and substitution
Step-by-step explanation:
One way to find out if the expression is true, we can convert all the percentages into their decimal equivalence.
60% = 0.6
10% = 0.1
6% = 0.06
Now let's substitute the values.
0.06 = 0.6 x 0.1
0.06 = 0.06
Since 0.06 is equal 0.06, this then proves that it is true.
Well.. There's 3y-2=y+4 right?
Add 2 and you get 3y=y+6
Minus y- you get 2y=6
Divide it at 2 and you get y=3.
Sorry for the explanation but I'm from another country and this is the best I can
Amount needed=earned+already have
205=earned+30
earned=7 times number of hours=7h
205≤7h+30
we used the less than or equal to because he needs at least 205, means 205 or greater must be earned
205≤7h+30
minus 30 both sides
175≤7h
divide both sides by 7
25≤h
needs to work at least 25 hours
To round 2.83 centimeters to the nearest whole number, use the following:
"five or above, give it a shove. four or below, keep it low."
So, since the number is 2.83, keep the 3 low (make it a zero)
Now the number is 2.8
Since 8 is over 5, you round up.
2.83 has become the whole number 3
