Answer:
1 pound of gummy bears = $3.20
1 pound of jelly beans = $7.50
Step-by-step explanation:
1.8 pounds of gummy bears + 0.6 pounds of jelly beans
= $10.26
1.2 pounds of gummy bears + 1.5 pounds of jelly beans
= $15.09
2.5 × (1.8 pounds of gummy bears + 0.6 pounds of jelly beans) = 2.5 × $10.26
--> 4.5 pounds of gummy bears + 1.5 pounds of jelly beans = $25.65
(4.5 pounds of gummy bears + 1.5 pounds of jelly beans) - (1.2 pounds of gummy bears + 1.5 pounds of jelly beans) = 3.3 pounds of gummy bears
3.3 pounds of gummy bears
= $25.65 - $15.09
= $10.56
1 pound of gummy bears
= $10.56 ÷ 3.3
= $3.20
1 pound of jelly beans
= [$10.26 - ($3.20 × 1.8)] ÷ 0.6
= $4.50 ÷ 0.6
= $7.50
Answer:
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary, so ...
m∠A + m∠C = 180°
Substituting the given expressions, we have ...
(3x +6)° + (x+2)° = 180°
4x +8 = 180 . . . . . . collect terms, divide by °
x +2 = 45 . . . . . . . . divide by 4
3x +6 = 135 . . . . . . multiply by 3
This is the value of angle A in degrees, so ...
m∠A = 135°
Answer:
The original number = 48.8
Step-by-step explanation:
Let the number be x.
According to the question ,
