consider first number is = x

formula,

(n / 2)(first number + last number) = sum,

7/2(x+x+6)= 945

2x+6= 945×2/7

2x+6 = 270

2x= 270-6

x=264/2= 132

5( x + 7) - 3 ( x - 4) = 7x + 2 what is x?
S_A_V [24]

Answer:

x=9

Step-by-step explanation:

5( x + 7) - 3 ( x - 4) = 7x + 2

Distribute

5x+35 - 3x +12 = 7x +2

2x +47 = 7x+2

Subtract 2x from each side

2x+47-2x =7x -2x+2

47 = 5x+2

Subtract 2 from each side

47-2= 5x+2-2

45= 5x

Divide by 5

45/5 =5x/5

9 =x

True or false 120% of a whole number is always greater than the number? and why?
Stells [14]
I can only use math to explain it. What is 100%?
100% = \frac{100}{100} 
percent means per 100.
so 120% = 120/100 = 1.2
120% of a whole number. For example 120% * 10 = \frac{120}{100} * 10 = 12
is it greater than 10.
