Ok remember
1st decimal place=tenths=x/10
2nd=hundreths=x/100
3rd=thoustands=x/1000
each place adds a zero
0.5
5 is in tenths place so 5 tenths aka 5/10=1/2
0.66 goes to hundreths so 66/100=33/50
0.7 is also in tenths so 7/10
CR:RB = 2:3
CB:CB = 2:5
AQ:AB=2:5
That means we start at A and go 2/5 along the way toward B to get Q:
Answer: Q=(-2,-4)
Answer:
7/10
Step-by-step explanation:
You need to represent the number of males in terms of females.
Explanation:
Since you know the number of males relative to females, it makes sense to represent the number of females as a variable, let's say f.
So then the number of males is <span>f+240</span> and we know that the number of males plus the number of females is 2500. Knowing this, we can write an equation: <span>f+<span>(f+240)</span>=2500</span>. I put the number of males in brackets there just to make it easy to recognize.
This equation can be condensed into <span>2f+240=2500</span> and then solved:
<span>2f=2500−240</span>
<span>f=<span><span>2500−240</span>2</span></span>
<span>f=1130</span>
Then, we know the number of females, and we can solve for the number of males from here using our male formula: <span>males=f+240</span>. You should then get 1370 as the number of males.
Checking this answer, we see that 1130 + 1370 does equal 2500.
