Answer:
600 decimeters
Step-by-step explanation:
multiply the meter length by 10
60x10=600
Answer:
y=7
x=-7
Step-by-step explanation:
2(-3x - 7y )= 2(-28)
3(2x+ 3y)=3(7)
-6x - 14y = -56
6x + 9y = 21
Add the two equations
-1(0x - 5y)= -1(- 35)
5y = 35
Divide both sides by 5
y=7
Substitution
6x + 9(7) = 21
6x + 63 = 21
Subtract 63 from both sides
6x = -42
Divide both sides by 6
x= - 7
Answer:
−7×(−6)×5= 210
Step-by-step explanation:
Since 4 peaches x 2 =8, you would would only be able to buy 6 mangos since $1.25 x 6 mangos =$7.5 so it would be $7.5+$8=$15.5 and 6 mangos+4 peaches=10 in total. And he would also save $5.00! :)

Width= W
length=2w+11
diagonal=2w+13
use the Pythagorean Theorem
(2w+13)^2=w^2+(2w+11)^2
4w^2+52w+169=w^2+4w^2+44w+121
simplify
52w+169=w^2+44w+121
w^2+44w-52w-169+121=0
w^2-8w-48=0
factor
(w-12)(w+4)=0
w-12=0
w=12 inches (width)
l=2*12+11=35 inches (length)
