C) -23x + 12 .. You're going to multiply the 4 to what's inside the parenthesis. So you'll get 12-24x+x Then just add the like terms which are the x's. 12-23x or -23x+12

U=1-3v/vt-w make t the subject
Jobisdone [24]
u = 1 - \dfrac{3v}{vt-w}

\dfrac{3v}{vt-w} = 1 - u

3v = (1 - u)(vt - w)

3v = vt - w - uvt + wu

vt - uvt = 3v + w - wu

t(v - uv) = 3v + w - wu

t =  \dfrac{3v + w - wu}{v - uv}

Masteriza [31]

The problem statement is not clear regarding which money is invested. We will assume it is the 80% of $8750 that is set aside for future education. That amount is

... 0.80 × $8750 = $7000

If x represents the amount invested at 7%, then the total interest earned is

... (7000 -x)×4% + (x)×7% = 420

... 280 +0.03x = 420

... x = 140/0.03 ≈ 4666.67

$4666.67 was invested at 7%.

$2333.33 was invested at 4%.
