Answer:
x = 2/5, y= -22/5
Step-by-step explanation:
4x−y=6;3x−2y=10
Step: Solve4x−y=6for y:
4x−y+−4x=6+−4x(Add -4x to both sides)
−y=−4x+6
-y/-1 = -4x +6 over -1 (Divide both sides by -1)
y=4x−6
Step: Substitute4x−6for y in 3x−2y=10:
3x−2y=10
3x−2(4x−6)=10
−5x+12=10(Simplify both sides of the equation)
−5x+12+−12=10+−12(Add -12 to both sides)
−5x=−2
-5x/-5 = -2/5 (Divide both sides by -5)
x= 2
/5
Step: Substitute 2/
5 for x in y=4x−6:
y=4x−6
y=4 (
2/
5
) −6
y= −22
/5
(Simplify both sides of the equation)
x = 2/5, y= -22/5
Answer:
The cross multiplication would be 10(350) = 22(x).
Step-by-step explanation:
We would first convert meters to centimeters. There are 100 cm in a meter; this means 3.5 m = 3.5(100) = 350 cm.
The ratio of the height to base of the model is 10/22. The ratio of the playhouse would then be x/350. This gives us
10/22 = x/350
Cross multiplying, we would have 10(350) = 22(x).
Answer:
3. 15 Cubes
4. 60 ft per sec , 180 ft
5. 58 yards per min
6. $7.50, $18.00
Step-by-step explanation:
3. Number of Cubes in 7 bowls = 35
Number of Cubes in 1 bowls = 
Number of Cubes in 3 bowls =
4. Distance ran by Zebra = 420 ft
Time taken = 7 seconds
Speed = 
=60 ft per sec
Hence
Distance = speed x time
Distance covered in 30 seconds = 60 x 30 = 180 Ft
5. Distance travelled = 870 yards
Time taken = 15 mins
Speed =
yards per min
6. Cost of 3 pounds of apple = $4.50
Cost of 1 pounds of apple = 
=$1.50
Cost of 5 pounds of apple = 5 x $1.50 =$7.50
Cost of 12 pounds of apple = 12 x $1.50 =$18.00
