Solve the system of equations
-3x+2y=-6
5x-2y=18
Please help me
Answer:
the answer is (x,y) = (6,6)
Step-by-step explanation:
1) first solve the equation for 2y
you should've gotten:
2y = -6 + 3x
5x - 2y = 18
2) substitute the value of 2y into the equation
5x - 2y = 18
so, 5x -(-6 + 3x) = 18
3) now solve 5x -(-6 + 3x) = 18
4) from that solving that equation, u should've gotten x = 6
5) now plug in 6 for x in the other equation, solve for y
( • stands for multiplication if u didn't know, we use this in higher levels of math so multiplication symbols and x variables aren't confused)
5 • 6 - 2y = 18
6) after solving for y in the previous equation, u should've gotten y = 6
7) now we know that x = 6 and y = 6, however it is always important to check if ur answer is correct by plugging in the x value y values u ended up with into the original system of equations.
checking ur work would look something like this:
2(6) = -6 + 3(6)
5(6) - 2(6) = 18

A six-sided fair die and an eight-sided fair die are rolled together. What is the probability of getting numbers whose sum is a multiple of 3? A 1/18 B 1/4 C 1/3 D 4/9 E 2/3
Answer:
C 1/3
Step-by-step explanation:
The numbers on a 6-sides die are 1, 2, 3, 4, 5, 6.
The number of an 8-sided die are 1, 2, 3, 4, 5, 6, 7, 8.
All the possible sums are:
2, 3, 4, 5, 6, 7, 8, 9,
3, 4, 5, 6, 7, 8, 9, 10,
4, 5, 6, 7, 8, 9, 10, 11,
5, 6, 7, 8, 9, 10, 11, 12
6, 7, 8, 9, 10, 11, 12, 13
7, 8, 9, 10, 11, 12 ,13, 14
The multiples of 3 are shown in bold and italic.
There are 48 possible sums.
16 sums are multiples of 3.
p(numbers whose sum is a multiple of 3) =
(number of outcomes that are multiples of 3)/(total number of possible outcomes)
p(numbers whose sum is a multiple of 3) = 16/48
p(numbers whose sum is a multiple of 3) = 1/3

In triangle GHJ, mH = 85° and mG = 60°.
Choose the correct symbol to put in the blank.
HJ ___ JG
<
=
>
Answer: The correct symbol is '<'.
Step-by-step explanation:
Given: In triangle GHJ
[tex]m\angle H=85^{\circ}[/tex] and [tex]m\angle G=60^{\circ}[/tex]
Here angle H is opposite to side JG and angle G is opposite to side HJ
We know that,
The side opposite to the greater angle of a triangle is greater.
Since [tex]m\angle H> m\angle G[/tex]
Then, JG > HJ
Hence, HJ < JG

Factor the expression using the GCF 7+14
Answer:
We found the factors and prime factorization of 7 and 14. The biggest common factor number is the GCF number. So the greatest common factor 7 and 14 is 7.
Step-by-step explanation:
The value of the Expression 7+ 14 using the GCF is 21.
What is Greatest Common Factor?The largest factor that splits both numbers is said to be the greatest common factor. List the prime factors of each integer before calculating the greatest common factor. One 2 and one 3 are shared by those aged 18 and 24. The GCF of 18 and 24 is 2 * 3 = 6, which we multiply to obtain.
Given:
We have to add 7 + 14
Factorise the terms separately
7 = 7 x 1
14 = 7 x 2
So, the Greatest Common Factor is 7.
Thus, 7+ 14 = 7(1+ 2) = 7 x 3= 21

x≤3 is the solution of the inequality 3x−4≤5
What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
The given inequality is 3x−4≤5
Three times of x minus four lesser than or equal to five.
We have to solve for x
Add 4 on both sides of the inequality
3x≤5+4
