If 2 is added to seven times a number and equals 8 more than six times a number what is the number

Answers

Answer 1

Answer: Seven times a number is 7x; 6 times a number is 6x and then solve7x+2=6x+8X+2=8X=6

Answer 2

Answer: Your word equation turned into an operation would be: 2+7n=8+6n. To complete this equation you have to balance it out so only n would be put on one side. So, try subracting 6n on both sides so it can be on the same side as 7n:2+7n-6n=8+6n-6n.Therefore the 6n on the right side has now switched over to the left. Then, you need to switch the 2 onto the right side by subtracting it on both sides as well:2+7n-6n-2=8-2The 2 has now been switched. After, subtract 7n-6n=1n, and 8-2=6. The equation then becomes:1n=6.To isolate n from 1, divide 1n by 1 and 6 by 1. Your equation afterwards should be: n=6/1, or as simplified: n=6.

B) 8/7
C) -7/8
D) -8/7

Answers

$k:y=m_1x+b\nl:y=m_2x+c\n\nl\ \perp\ k\iff m_1m_2=-1$
We have:
$m_1=(7)/(8);\ m_2=?$
Substitute:
$(7)/(8)m_2=-1\ \ \ \ |\cdot(8)/(7)\n\nm_2=-(8)/(7)$
Answer: D)

Hey there !

When two lines are perpendicular , the product of their slope is -1 ,

m1 × m2 = -1
7/8 × m2 = -1

m2 = -8/7 Ans.

This is urgent!!! Increase £400 by 3.2% how do you do it

Answers

to get 3.2% : 400 x $(3.2)/(100)$ = 12.8

12.8 + 400 = £412.80

10% of 400 = 40
1% of 400 = 4
0.1% of 400 = 0.4

(3 x 1%) + (2 x 0.1%) = 3.2%
3.2% = 12.8
Answer is 412.8 pounds
