12x+6=9x-15 (subtract variables, smaller one)
-9x. -9x
3x+6=-15 (subtract 6 to both sides)
-6. -6
3x=-21 (divide 3)
x=-9

Answer:

it’s -7

Step-by-step explanation:

because when you subtract the 6 from both sides you get 12x=9x-21 then subtract the 9x from both sides to get 3x=-21 then divide both sides by 3 to get x=-7.

What is x 5/9 of x is 90<br>help assap
blsea [12.9K]

Answer:

<h2>162</h2>

Step by step explanation

\frac{5}{9} x  = 90

Multiply both sides of equation by 9/5

\frac{9}{5}  \times  \frac{5}{9} x =  \frac{9}{5}  \times 90

Reduce the numbers with Greatest common factor 9

\frac{1}{5}  \times 5x =  \frac{9}{5}  \times 90

Reduce the numbers with G.C.F 5

x =  9  \times 18

Multiply the numbers

x = 162

Hope this helps..

Best regards!!

Kane rolls a dice and flips a coin at the same time. What is the probability he rolls a 2 or lower and the coin lands on heads?
lord [1]

Answer:

The probability he rolls a 2 or lower and the coin lands on heads is 16.66%.

Step-by-step explanation:

Since Kane rolls a dice and flips a coin at the same time, to determine what is the probability he rolls a 2 or lower and the coin lands on heads the following calculation must be performed:

Given = 6 sides = 2/6

Coin = 2 sides = 1/2

2/6 x 1/2 = X

0.333 x 0.5 = X

0.1666 = X

0.1666 x 100 = 16.66

Therefore, the probability he rolls a 2 or lower and the coin lands on heads is 16.66%.

1. Jin bought 3 small candles and 1 medium candle for $3.85. Trish bought 4 small candles and 5 medium candles for $10.45.
nasty-shy [4]
<span>We will use s for the cost of a small candle and m for the cost of a medium candle.

(a)
The candles and price for Jin can be written as:
3s+1m=$3.85
The candles and price for Trish can be written as:
4s+5m=$10.45

The system of equations that we have is:
</span>3s+1m=$3.85
4s+5m=$10.45

(b)
We will use substitution to solve this problem.
From the first equation we can find out m:
3s+1m=$3.85
1m=$3.85-3s

Now we insert this into second equation and we solve it for s:
4s+5($3.85-3s)=$10.45
4s+$19.25-15s=$10.45
-11s=-8.8
s=$0.8
Now we can find m:
m=$3.85-3*$0.8
m=$3.85-$2.4
m=$1.45

(c)
The candles and price for Jin can be written as:
2s+1m=price
We can insert values for s and m:
2*$0.8+$1.45=price
price=$1.6+$1.45
price=$3.05
