7 0

Step-by-step explanation:

95%= 95/100×180/1

0 will cancel 0

2 can divide so 10 ÷2 = 5 and 18÷2= 9

5 can divide 95 =19

19×9= 171

Question 9 of 15 (1 point)

mote1985 [20]

The number is -9

Step-by-step explanation:

Let x be the number then according to given statement

$4x+10 = x-17$

Subtracting 10 from both sides

$4x+10-10 = x-17-10\\4x = x-27$

Subtracting x from both sides

$4x-x = x-x-27\\3x = -27$

Dividing both sides by 3

$\frac{3x}{3} = \frac{-27}{3}\\ x = -9$

Verification:

$4(-9)+10 = -9-17\\-36+10=-26\\-26=-26$

The number is -9

Clayton has $500 in his retirement account, and Jason has $400 in his. Clayton is adding $10 per day, whereas Jason is contribut

daser333 [38]

Answer:

$1000

Step-by-step explanation:

We can form an equation for Clayton's account: C = 500 + 10x

We can form an equation for Clayton's account: J = 400 +12x

(where x is the number of days)

When the two accounts will contain the same amount, it means: C = J

<=> 500 + 10x = 400 +12x

<=> x =50

After 50 days, there accounts will be balance. Then, we substitue x into any of the 2 equation to find out the amount: 500 + 10(50) = $1000
