The hypotenuse is twice the short leg. The answer is 8
D + q = 40
.10d +.25q= $7.75
d +q = 40
d =40-q
.10(40-q) +.25q= $7.75
4 - .10q + .25q =7.75
4 +.15q =7.75
4-4 +.15q =7.75-4
.15q= 3.75
.15q/.15 = 3.75/.15
q = 25
d =40-25
d = 15
Check
.10(15) +.25(25)= $7.75
1.5+6.25=7.75
7.75=7.75
Answer:
-2,4/3
Step-by-step explanation:
ax²+bx+c=0

Okay!
1) Round both numbers -
2674 - 2700
1847 - 1800
2) Subtract 2700 and 1800
2700 - 1800 = 900
Therefore, the answer is 900
The approximate distance between points (-7,2) and (11,-5) is
=√[11-(-7)]²+[(-5-2)]²
=√(18)²+(-7)²
=√324+49
=√373
