2600 increased by 3%
there are 2 ways to do this...
(1) 2600 + 0.03(2600) = 2600 + 78 = 2678 per quarter
or
(2) 2600 * 1.03 = 2678 per quarter
To get your answer, follow my method :
First you take away 24 from 250=226
Then you half 226=113 which is Mark's weight
As Mike weights 24 pounds more that Mark, you have to add 24 back=137
So your answer is :
Mark weights 113 pounds and Mike weights 137 pounds.
Answer:
x = 574 and x = - 
Step-by-step explanation:
(1)
0.25x = 143.5 ( isolate x by dividing both sides by 0.25 )
x = 574
(2)
- 4x + 
= 3 ( subtract from both sides )
- 4x = 3 ( divide both sides by - 4 )
x = -
He spent 12 hours studying science.
The ratio of time Jerome spends on math and science, respectively, is 4:3. We know he spent 16 hours studying math last week, so our proportion looks like:
4/3 = 16/x
Cross multiply:
4*x = 3*16
4x = 48
Divide both sides by 4:
4x/4 = 48/4
x = 12
Since Jerome and Ross spent the same amount of time on science, then Ross also spent 12 hours on science.
Choice urn_1: 1/3
choice R: 5/8 ==>1/3*5/8=5/24
Choice urn_2: 1/3
Choice R: 3/4 ==> 1/3*3/4=1/4
Choice urn_3: 1/3
Choice R:4/6=2/3 ==> 1/3*2/3=2/9
Total: 5/24+1/4+2/9=15/72+18/72+16/72=49/72
