Answer:
x = 24
Step-by-step explanation:
1.) put the equations together and equal them to 180
2x + 4 + 6x - 16 = 180
2.) combine like terms
8x - 12 = 180
3.) divide both sides by 8
8x = 192
4.) simplify
x = 24
Answer:
y=21.14
Step-by-step explanation:
x=6 because after 6 weeks
y= 3.27(6)+ 1.52
y=19.62 + 1.52
y=21.14
Answer:
11 minutes
Step-by-step explanation:
Because she types only 140 words in 4 minutes so if you add
140+140=280
if you divide
140/4 you get 35
so every minute she types in 35 words. So multiply
11 times 35 and you exactly get 385.
After the division, we get 8.99031476998. This rounds to <u>9</u> as a whole number, which is the answer.
When rounding to a whole number, the digits following the decimal decide what number it rounds to. If it is 0-4 it rounds to whatever the whole number currently is E.G.
8.1 would round to 8
But if its 5-9 it rounds to one above, like in our current case.
8.5 rounds to 9.
42.414 rounds to 42.
42.94149124 rounds to 43.
