Help? thanks babbbeeezzz

1/2

Step-by-step explanation:

To solve this, you have to do the inverse operation thing, so our equation is:

1/5 + 3/10 = 1/2

So 1/2 - 3/10 = 1/5

1/2

Step-by-step explanation:

If you give them all common denominators you get x-3/10=2/10 now all you have to do is add what you have together and you get 5/10.If you check your work you get: 5/10 - 3/10 = 2/10 and that is true! 5/10 is the same as 1/2! :)

answer: yes, he is correct

step-by-step explanation: 10x-1=59

                                              1-1=0     59+1=60

60/10=x=6

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
