Answer:
5 ft
Step-by-step explanation:
Area of a rectangle
length x width
(3x-2) * (x) = 65
3x^2 - 2x - 65 = 0
Δ/4 = 1 + 195 = 196
x1 = (1 + 14)/3 = 5
x2 (1-14)/3 = -13/3 (not acceptable because a length can’t be negative)
Answer:
(i)unique solution
Explanation:
We solve for x1 thus in the first equation:
x1-3x3=-3
x1-9=-3
x1=-3+9
x1= 6
We solve for a thus in the second equation:
2x1+ax2-x3=-2
2+a2-x3=-2
a2-x3=-4
a2=-4+x3
Answer:35.71
Step-by-step explanation:
Answer:
8 sets of twenty sandwiches.
Step-by-step explanation:
first you find the answer to 3 x __ = __ lets make the answer 24. That makes the other blank 8. Now subtract 24 from 184 and you should get 160. Divide 160 by 20 and you'll get how many set the customer ordered of twenty sandwiches. Multiply by twenty and you will get the whole amount they ordered.
Answer:
33 °C
Step-by-step explanation:
Put 92 where F is in the equation, and solve for C.
92 = 1.8C +32 . . . . substitute for F
60 = 1.8C . . . . . . . . subtract 32
60/1.8 = C ≈ 33.33 ≈ 33 . . . . . divide by the coefficient of C, round the result
The temperature is about 33 °C.
