the sum of three number is 202, the second is three more than the first number, the third number is three times the second numbe
sertanlavr [38]

Answer:

x = 38

y = 41

z = 123

Step-by-step explanation:

x + y + z = =202

y = x + 3

z = 3y = 3(x + 3) = 3x + 9

<u>x</u> + <u>y</u> + <u>z</u> = <u>x</u> + <u>x + 3</u> + <u>3x + 9</u> = 5x + 12 = 202

5x + 12 = 202

5x = 190

x = 38

y = x + 3 = 41

z = 3y = 123

Stan pays a 10% deposit to put a pool table on lay-by.
Lera25 [3.4K]

Answer:

$1431

Step-by-step explanation:

If Stan pays a 10% deposit, he pays $159. 10% of $1590 is simply 0.1 * 1590 = 159. Assuming this is the only amount he pays, he then simply needs to pay the full price minus $159. We can find this by simply subtracting 159 from 1590 to get 1431. Stan still needs to pay $1431.

EleoNora [17]

Answer:

.90(85.00) would give the same result

Step-by-step explanation:

Rhonda is using the total cost of the item ($85.00) multiplied by the discount (10%) to find the total discount:  85 x 0.10 = 8.50.  Once Rhonda subtracts the discount ($8.50) from the total:  $85 - $8.50 = $76.50.  The other way to look at the problem, is that Rhonda is only paying for 90% of the total cost of the items, instead of 100% since she is receiving the 10% discount.  So, she would get the same final total by multiplying the cost of the items ($85.00) by 90%, or 0.90.

Line n passes through points (7, 12) and (4, 15). What is the slope of a line that
vitfil [10]
So anytime we have a slope and want to find the slope of a perpendicular line, we just have to remember a perpendicular line's slope is the negative reciprocal (reciprocal means flip the fraction). So if we had a slope of 3/4, the slope perpendicular to it would be - 4/3.


First we need to find our slope, to do this we take the change in y over the change in x like so:

(15-12)/(4-7) = - 3/4

The slope perpendicular to this is 4/3.

(4/2)^2*3.4*4
Andrej [43]
The original expression evaluates to 54.4 as shown in the first working.

_____
For some reason, 3.4 got transcribed to be 1.7 in the 3rd line of the second working. There is no math operation in the expression that requires 3.4 to be divided by 2.
