3 1/8 means 8 x 3 + 1 = 25/8
Step-by-step explanation:
4/5 x 25/8
= 4x25/5x 8
= 100/40
= 5/2
Answer:
C
Step-by-step explanation:
B can immediately be eliminated because it has an area of 14.
A and C have an area of 10.
So add the sides.
C:
4 + 4 + 1 + 1 + 2 + 2 + 1 + 3
= 18
A: 3 + 3 + 2 + 2 + 1 + 1 + 1 + 1 =
10 + 4 =
14
so what I do is caunt or just add 7 +8 it will equal 15
2(x - 2) + 3(x + 1) = 9
2x - 4 + 3x + 3 = 9 <em>distributed the 2 and 3 on the left side</em>
5x - 1 = 9 <em>added like terms (2x + 3x) and (-4 + 3)</em>
5x = 10 <em>added 1 to both sides</em>
x = 2 <em>divided 5 from both sides</em>
Answer: x = 2
