Lisa invest $4000 in two types of bonds , bond a and bond b a offers 10%return . lisa invest $x and $y inbond b her tostados investment is 350. the system of linear equations defining the situation is a. x+y=4000and 10x+6y=340 b. x+y=4000and 0.06x+0.1y=340 c. x+y=340and 0.1x+0.06y=4000 d. x+y=4000and 0.1x+0.06y=340 the amount lisa invest ed at the rate of 10%is a.1000 b.1500 c2500 d3500 and the amount she invested at the rate of 6%is a. 500 b1500 c2500 d3000

x+y=4000(1)

10x+6y=340*100⇒5x+3y=17000(2)

(2)- 3*(1)⇒ 2x=5000⇒x=2500,y=4000-2500=1500

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
