Answer:
Step-by-step explanation:
total =20
red=10
P(red)=10/20=1/2
( 356 x 280 ) - ( 103 x 60 )
99 680 - 6180 = 93500
answer = 93500
Irst thought: since he needs 7 3/4 tons, and each load can carry LESS than a ton, he'll need to make MORE than 7 3/4 loads. So when you get your answer, make sure it it passes that common sense test. Next: He's got to divide the 7 3/4 ton total among all those loads, 3/4 ton at a time. So he needs to divide: 7 3/4 divided by 3/4. It will be easier to do the math if we turn 7 3/4 into an improper fraction, which will be 31/4. So we have to divide 31/4 divided by 3/4, which will give us 10, with 1/4 left over, for a total of 10 1/4 loads. BUT: the wording is that each load carries AT MOST 3/4 ton, so he may carry less than that amount in any given load(s). So he needs to do an amount GREATER THAN OR EQUAL TO 10 3/4 loads. For practical purposes, that means he has to fill his truck (at least part way) 11 different times. (Think of it as completely filled the first 10 times, and 3/4 filled on the 11th/final time.)
Answer:
Step-by-step explanation:
Q1: 4=10x+5
4-5=10x
-1=10x
-1/10=10x/10=-0.1
Q2:s=3w+2x
s-3w=2x
s-3w/2=2x/2.
