-15+7=-8
Adding numbers with different signs makes it subtraction and the answer will have the sign of the bigger number
7(a - 10) = 13 - 2(2a + 3)
7a - 70 = 13 - 4a - 6 = 7 - 4a
7a + 4a = 7 + 70
11a = 77
a = 77/11 = 7
a = 7.
Answer:
C. y<3
Step-by-step explanation:
We are required to determine the solution set of the inequality
Step 1: Add 9 to both sides
Step 2: Divide both sides by 15
The solution set of the given inequality is: y<3.
The correct option is C.
Answer:
Yes by SAS
Step-by-step explanation:
If you look at the triangles they have 2 side lenght in common (and since it is a right triange they have all the sides in commmon) and they share an angel
In other words 2 sides are conurent with an angle betwene them.
You would need to rotait the shape 90 degrese.
Answer:
x = 25
Step-by-step explanation:
it's an isosceles triangle so base angles are the same
3x - 30 = 45
Add 30 on both sides
3x = 75
divide both sides by 3
x = 25
