Answer:
x = - 6
Step-by-step explanation:
given the 2 equations
3x + 5y = - 13 → (1)
2x - 3y = - 15 → (2)
To eliminate y from the equations we require their coefficients to be equal so that when we add the equations y is eliminated
multiply equation (1) by 3 and equation (2) by 5
9x + 15y = - 39 → (3)
10x - 15y = - 75 → (4)
add (3) and (4) term by term
(9x + 10x) + (15y - 15y) = (-39 - 75 )
19x = - 114 ( divide both sides by 19 )
x = - 6
To find y substitute x = - 6 into either (1) or (2)
The answer I got is d = 78

Answer:
4 feets = 48 inches
2 miles = 10,560 feets
1 2/3 yards = 5 feets
3 1/2 yards = 126 inches
Step-by-step explanation:
Recall :
1 Feet = 12 inches
1 MILE = 5280 feets
1 yard = 36 inches
1 yard = 3 feets
If 1 feet = 12 inches
4 feets will be ; (12 * 4) inches = 48 inches
If 1 mile = 5280 feets
2 miles will be ; (5280 * 2) = 10,560 feets
If 1 yard = 3 feets
1 2/3 yards will be ; (5 /3) * 3 = 5 feets
If 1 yard = 36 inches
3 1/2 yards will be ; (7 /2 ) * 36 = 126 inches
