What two numbers multiply to 30 and add to -17
victus00 [196]

Answer:

-15 and -2

Step-by-step explanation:

Since a negative times a negative equals a positive, but when added, still stays a negative, the factors must both be negative.

Negative Factors of 30:

-30 + -1 = -31

-15 + -2 = -17

-10 + -3 = -13

-6 + -5 = -11

The two factors of 30 that add up to -17 are -15 and -2.

Hope this helps. Have a nice day.

14-2(x+8)=5x-(3x-34)
Scilla [17]

Answer:30=-34


Step-by-step explanation:

First you distribute so 2×X is 2X

2×8 is 16 then you do the other side but you put a one in front of the- so it goes 1 times 3x is 3x and you turn the minus into a plus sign and turn the positive 34 into a negative 34 so -34× 1 is -34 then write that out to look like 14-2X+16= 5X -3X + -34 then you add or subtract the commons which is 14+16= 30 and 5X-3X=2X so now your equation is 30-2x=2X+(-34) then you want to get your X on the same side so you subtract 2X from the right side and the left side then your left 30=-34

the original price of a collectible model airplane is $115. The discounted price is $99. What is the percent of discount to the
storchak [24]

Answer:

$99/$115 x 100% = 86.086% of the original price  

So 100% - 86.086  

= 13.9 = 14%  

Or you could just do (115 - 99) x 100 which gets the same answer.

One of the digits of a two digit number is three times the other digit. If you interchange the digits of this two digit number a
STatiana [176]

Answer:

62

Step-by-step explanation:

well, we start by expressing the number:

a b

we understand that using the above expression, the value of the number is 10a + b

using the information in the question,

a = 3b (1)

and,

11b + 11a = 88 (2) (derived using 10a + b form)

hence, when substituting (1) into (2):

11b + 33b = 88

44b = 88

b = 2 (3)

sub (3) into (1)

a = 6

hence, the number is 62
