Answer:
see explanation
Step-by-step explanation:
32 - 7x = 2x - 3(4x - 5) ← distribute parenthesis
32 - 7x = 2x - 12x + 15
32 - 7x = - 10x + 15 ( add 7x to both sides )
Anna made her error here in that she subtracted 7x from both sides
32 = - 3x + 15 ( subtract 15 from both sides )
17 = - 3x ( divide both sides by - 3 )
- 
= x ← is the solution
1st box is 28, 2nd box is 42!! If you need an explanation you can message me:-)
Step-by-step explanation:
The expression is: 7 × -5 - 7
The value of the expression is: -42
-35 - 7 = -42
You're going to need the pythagorean theorem, which is a^2+b^2=c^2. 15^2 is 225, 17^2 is 289, and if you work out the equation you get to an answer of 8 inches.
You can multiply a fraction with the same numerator and denominator like 2/2, which is also one (does not change original fraction).
6/9*2/2= 12/18
or any other number
6/9*3/3=18/27
