Answer:
The Answer is 29/18 and in mixed form it is 1 11/18
Step-by-step explanation:
Steps for adding fractions
Find the least common denominator or LCM of the two denominators:
LCM of 9 and 6 is 18
Next, find the equivalent fraction of both fractional numbers with denominator 18
For the 1st fraction, since 9 × 2 = 18,
7
9
=
7 × 2
9 × 2
=
14
18
Likewise, for the 2nd fraction, since 6 × 3 = 18,
5
6
=
5 × 3
6 × 3
=
15
18
Add the two like fractions:
14
18
+
15
18
=
14 + 15
18
= 29/18
So, 7/9 + 5/6 = 29/18
In mixed form: 1 11/18
Hope this helps you out :D
It’s 2 equations so in order to solve the previous system, you can use different methods, as for example substitution or addition of equations. In this case, you use the second one, due to the fact you have 7x in one equation and -7x in the other equation. In this way you can easily eliminate variable x and then solve for y. With the value of y you can replace in any of the two equations and solve for x.
7x-y=-1
-7x+3y=-25
Summarizing, you proceed as follow:
- add up the given equations
7x - y = -1
-7x+3y=-25
——————
0 +2y=-26
- solve for y in the previous equation
2y=-26
y=-26/2
y=-13
- replace the obtained value of y in one of the given equations, and solve for x
7x-(-13)=-1
7x+13=-1
7x=-1-13
7x=-14
x=-14
x=-14/7
x=-2
Hence, the solution of the given systems of equation is:
X=-2
Y=-13
Answer:
alright so 1 and 2 are equal to each other because there congruent angles. When angkes are congruent to each other or in other words the opposite to each other there equal.
