4. Division property of equality
Step-by-step explanation:
7x - ½ ( 8x+ 2 ) = 6 Distribute the -½
7x - 4x - 1 = 6 Combine like terms
3x - 1 = 6 Add 1 on both sides
3x = 7 Divide 3 on both sides
x = 7/3
Answer:12 cups of sugar are needed in the recipe
Step-by-step explanation:
6 ¼ + 5 ¾ =11 4/4=12
We set up an equation: ?/43 -87= -75

⇒ ?/43= 12
⇒ ?= 12*43
⇒ ?= 516
The unknown number is 516~

Answer:
70 Bikes
Step-by-step explanation:
[using b as a variable for bikes]
2800=-50b+90b
[2800 is total cost of store with-50 being cost per bike and 90 being selling point of bike]
2800=40b [simplified by combining -50 with 90]
70=b [divided 2800 by 40 to get the break even for the store]
