Is the open sentence 3z = 2z +5 true or false when z=5?

1 answer:

8 0

If 3z=2z+5 and z=5, then you’d just plug the 5 in.

3(5)=2(5)+5 —> 15=10+5 —> 15=15

This statement is TRUE because 15 does equal 15.

I hope this helps. :)

Two pounds of grapes cost $6.

velikii [3]

Answer:

leftmost empty cell: ⅓

rightmost empty cell: 3

Step-by-step explanation:

✔️If 2 pounds grapes cost $6, then x pounds of grapes cost $1.

Thus;

2 : 6 = x : 1

2/6 = x/1

Multiply both sides by

²/6 × 1 = x/1 × 1

²/6 = x

¹/3 = x

x = ⅓

✔️If 2 pounds grapes cost $6, then 1 pound of grapes cost $x.

Thus;

2 : 6 = 1 : x

²/6 = ¹/x

Cross multiply

2x = 6

Divide both sides by 2

2x/2 = ⁶/2

x = 3
