Answer:
First blank= -1
Second blank= 14
Step-by-step explanation:
Plug in x to the equation. 1/7 x (-7)= -7/7=-1
2=1/7(x) to divide fractions you multiply by the reciprocal
2 x 7/1= 1/7× 7/1
14/1=14
Answer:
The first question is (n*8) - 4
The second question is no.
Step-by-step explanation:
The first question, you add 8. The first is 1. 1 * 8 = 8 - 4 = 4.
Therefore, the equation is (n*8) - 4
The second question, you can plug in numbers. You can solve for a term. -100 + 17 = -83. -83 is not a multiple of -4. -100 is not a term.
Answer:
hey
Step-by-step explanation:
<span>It is easier to multiply. For example: 63 multiply by 7
</span><span>63 x 7 = (60+3) x 7 = 60 x 7 + 3 x 7 = 420 + 21 = 441
</span>
Another example : <span>25 x 73
</span>25 x 73 = (20+5) x (70+3) = 20 x 70 + 20x3 + 5x70 + 5x3
= 1400 + 60 + 350 + 15 = 1875
