1. Combine like terms, so add 2.4 to -4.8 to get -2.4
So now you should be left with .02(x+20)-2.4=-9
2. Now eliminate the -2.4 by adding 2.4 to both sides, getting .02(x+20)=-6.6
3. Multiply everything by 50 to make x+20=-333, since 50×.02=1
4. subtract 20 from both sides to get x=-353

We need to distribute the parenthesis before we do anything. 0.02(x+20)=0.02x+0.4; now let's put this into the equation.

2.4+0.02x+0.4-4.8=-9; this is all about making sure we get x on one side, isolated. We need to add all the like terms.

0.02x-2=-9; let's add 2 to both sides. 0.02x=-7; let's divide each side by 0.02 so that we can have x by itself. x=-350; let's plug -350 in as in the original equation to make sure that is our answer.

2.4+0.02(-350+20)-4.8=-9; let's add the parenthesis. 2.4+0.02(-330)-4.8=-9; let's multiply. 2.4-6.6-4.8=-9; let's subtract. 2.4-6.6=-4.2-4.8=-9

So, x=-350.

What life cycle adaptation allows a seahorse to make lots of babies in a short amount of time? (2 points)
Zielflug [23.3K]

The seahorse make a lot of babies because the male carries the babies while the female makes more eggs.

<h3>What is mating?</h3>

Mating is the process in which opposite or hermaphroditic organisms pair for reproduction.

During mating between the male and female seahorse mates, the female seahorse puts her eggs in the male pouch and the male fertilises the egg in his pouch. The eggs develop into baby seahorse in the father pouch.

-10(-2)+y = 4

20 + y = 4

y = -16

----------------

-10(-1)+y = 4

10 + y = 4

y = -6

----------------

-10(0) + y = 4

0 + y = 4

y = -4

----------------

-10(1)+y = 4

-10 + y = 4

y = 14

----------------

-10(2)+y = 4

-20 + y = 4

y = 24

----------------

I hope thi helps

A man invest 5,200,part at 4% and the balance at 3%. If his total income for the two investments is $194,how much money did he i
Fed [463]

Let the amount invested at 4% be = x

Let the amount invested at 3% be = y

Given is:

x+y=5200 or x=5200-y  .... (1)

As, total income for the two investments is $194, so equation is:

0.04x+0.03y=194   ....(2)

Putting value of x from (1) in (2)

0.04(5200-y)+0.03y=194

208-0.04y+0.03y=194

0.01y=14

y=1400

And x=5200-y

x=5200-1400=3800

Hence, money invested at 4% is $3800 and money invested at 3% is $1400
