Answer:

$t=\frac{x}{7}$

Step-by-step explanation:

You need to isolate the variable t. Use inverse operations for this.

7t can be seen as 7×t, and the opposite of multiplication is division. Divide both sides by 7:

$\frac{7t}{7}=\frac{x}{7}\\\\t=\frac{x}{7}$

The common term 7 on the left side cancels out.

Answer: B

Step-by-step explanation:

-10x² + 12x - 9 = 0

a=-10, b=12, c=-9

x = $\frac{-b+/-\sqrt{b^{2}-4ac}} {2a}$

= $\frac{-12+/-\sqrt{12^{2}-4(-10)(-9)}} {2(-10)}$

= $\frac{-12+/-\sqrt{144-360}} {-20}$

= $\frac{-12+/-\sqrt{-216}} {-20}$

= $\frac{-12} {-20}$ +/- $\frac{\sqrt{-216}} {-20}$

= $\frac{3} {5}$ +/- $\frac{6i\sqrt{6}} {-20}$

= $\frac{3} {5}$ +/- $\frac{3i\sqrt{6}} {10}$

The ratio of money in Terry's bank account to Faye's bank account was 3:7. Terry then put £220 in his account and Faye withdrew

Nesterboy [21]

Answer:

£910

Step-by-step explanation:

let 3x and 7x be the initial amounts in their accounts, then after alterations

Terry has 3x + 220

Faye has 7x - 300

After these changes the amounts are equal, hence

7x - 300 = 3x + 220 ( subtract 3x from both sides )

4x - 300 = 220 ( add 300 to both sides )

4x = 520 ( divide both sides by 4 )

x = 130

Faye initially had 7 × £130 = £910 in her account
