Answer:
3x + 17
Step-by-step explanation:
(5x +12) - (2x-5)
5x +12 - 2x+5
3x + 17
Y= -2x-5
Y=8x+5
^^ those two equations are basically the same so you put them side by side like:
-2x-5=8x+5
Subtract 5 on both sides which leads to:
-2x-10=8x
Add 2x both sides:
-10=10x
Divide both sides by 10
-1=x
Answer:
A
Step-by-step explanation:
using formula
area of triangle=1/2 × AB×AC×sinA
WHERE AB=10 andAC=15 and sinA=37○
Answer:
X^2-2X+1=0
Step-by-step explanation:
given,2X-X^2=1
or,-(X^2-2X)=1
or,X^2-2X=-1
or,X^2-2X+1=0 ,which is the req.equation in standard form.
The probability that Rachel will win the game is: 1/12
Step-by-step explanation:
The number cubes has six sides numbered between 1 to 6. the chances of each number are equally likely
Let S be the sample space
The sample space has 6*6 = 36 outcomes.
Now, Let A be the event that the sum of numbers on both number cubes is 10
A = {(4,6),(5,5), (6,4)
n(A) = 3
The probability that Rachel will win the game is: 1/12
