Answer:

Step-by-step explanation:

We can use the is/of=%/100 proportion...

x = 90

40 100

First, we need to multiply 90 by 40. 90x40=3,600.

Next, we have to divide 3,600 by 100. 3,600/100=36.

Rose needs to get 36 questions correct to get at least a 90%.

Hope this helps!! Have a great day C:

Which equation has infinitely many solutions?

raketka [301]

Answer:

Step-by-step explanation:

5.1 + 2y + 1.2 = -2 + 2y + 8.3 ( subtract 2y on each side)

5.1 + 1.2 = -2 + 8.3 ( collect like terms)

6.3 = 6.3

If the equation ends with a true statement (ex: 2=2) then you know that there's infinitely many solutions or all real numbers.
