Provide a) the **EQUATION** and b) the solution for the following:
ivolga24 [154]

Answer:

y= 2x + 85

y= $555

x= $235

Step-by-step explanation:

Let y be the amount the senior class raised

Let x be the amount the freshmen class raised

Insert known values

$555 = 2x + $85

Subtract 85 from both sides

$470 = 2x

Isolate the variable (x) by dividing each side by 2

$235 = x

Hope this helps! :)

Which statement about 5 multiplied by 1/8 must be true?
Kipish [7]

Answer:

The product is less than 1.

Since 5\times \frac{1}{8} = \frac{5}{1}\times \frac{1}{8}=\frac{5}{8}

and \frac{5}{8}= 0.625

which is less than 1, therefore we can say that the product is less than 1.
