3(4) + 12 + 12[4(6) - 10]
12 + 12 + 12(24 - 10)
12 + 12 + 288 - 120
192
Good 'ol ratio and proportion
so what yo do is
known ratio=unknown ratio
so first one
oranges
number of oranges to cost=5:2
find the cost of 2 dozen (24) oranges
number of oranges to cost=5:2
5:2=24:?
5/2=24/?
times both sides by 2 times ?
5 times ?=48
divide both sides by 5
?=9.6
2 dozen oranges costs $9.60
this one I can't see how many days
but for x days, the cost is x times $60
john drove some distance
distance to amount of gas is 48:2
how much gas needed for 78 miles

Answer:
5
Step-by-step explanation:
if x=2, then it would be 5/2 times 2. first, lets make 5/2 into a whole number, 2 1/2. that would be 2 1/2 x 2. lets do them indevidually. 1/2 x 2 is 1. and 2 x 2 is 4. now, if we add 4 and 1, that would give is a result of 5.
making the answer 5
The given number 0.044.
How the value if 4s related?
=> let’s give the place value of each digits first. There are 3 digits
after the decimal point.
=> 0 which is tenths, 4 which is hundredths and another 4 which is
thousandths.
Now, notice the we have 2 4s next to each other.
=> 4 hundredths
=> 4 thousandths
Thus, 4 hundredths is 10 times higher than 4 thousandths.
=> 0.004 x 10 , in where the value of 4 is thousandths
=> 0.04, in where when multiplied by 10 the value become hundredths.
