Add like terms just like you would anywhere else...
Answer:
(10x25) + (5x25)=375
Step-by-step explanation:
Ten times any number is easy because you just add a zero to the end. So mental math would say to break it into 10x25=250, plus 5x25=125, which equals 375
The range of the data is 12
Answer:
Angle A is 77°
x = 3
AC = 13
Step-by-step explanation:
Angles A, B and C MUST add up to 180°. If Angle C is 26°, then the sum of A and B and 26° = 180°. In other words, A+B = 180° - 26° = 154.
Since A and B are equal, A = B = 154°/2 = 77°
Since this triangle is isosceles, sides AC and BC are equal. Thus,
7x - 8 = 3x + 4, or
4x = 12. Then x = 3.
Since AC = 7x - 8, and x = 3, AC = 7(3) - 8 = 21 - 8 = 13
Answer:
linear
Step-by-step explanation:
linear equations are ones that go throught the origin if i remember correctly
