Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
2(x + -5) + x = x + (-6)
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Distributive Property] Distribute 2: 2x - 10 + x = x - 6
- [Addition] Combine like terms (x): 3x - 10 = x - 6
- [Subtraction Property of Equality] Subtract <em>x</em> on both sides: 2x - 10 = -6
- [Addition Property of Equality] Add 10 on both sides: 2x = 4
- [Division Property of Equality] Divide 2 on both sides: x = 2
Subtract 12 from each side
so it should look like this
-12v=-2v-18
now add 2v to each side
so it should look like this
-10v=-18
now divdie each side by -10
and you should get
v=9/5 or 1 4/5
$60. You change 25% to the decimal of .25 and multiply it by $240 to see what 25% of $240 is.

Answer:
66 cm squared
Step-by-step explanation:
split the shape into 2 rectangles, then use the numbers given to solve for the new shapes
3cm by 7cm for one and 5cm by 9 cm for the other (there are multiple ways to split the shape)
multiply those numbers
3 x 7 = 21cm ^2
5 x 9 = 45cm ^2
add them together
66cm ^2 (squared)
