If it’s a triangle then it has to equal 180
so 48+54+x=180
48+54=102
180-102=x
x=78
Answer:
20x - 8
Step-by-step explanation:
using the distributive property to simplify (5x-2)4, you would multiply the outside term (4) by each inside term (5x-2).
for example:
4 × 5x = 20x
4 × -2 = -8
once you distribute the 4 into 5x-2, you are left with 20x - 8 which needs no further simplifying
7/13 = about 0.54
-1 1/2 = -1.5
The answer is
-1.7, -1 1/2, 0.04, 0.1, 7/13
1. 2.00321
2. 2.01465
3. 2.0155
4. 2.04285
