Answer:
m = -4
Step-by-step explanation:
- 36 - m = 8(4+2m)
- 36 - m = 32+16m (to remove m from the left side, we need to add m to both sides)
- 36 = 32+17m (subtract 32 from both sides)
- 68 = 17m (divide by 17 on both sides)
-4 = m
Answer:
B
Step-by-step explanation:
1 yard is 3 feet.
The other ones give you 5 or more feet.
The expression 15t – 2t not equivalent to 2t – 15t because the negative sign in 15t – 2t belongs to the term 2t.
Solution:
Given expressions are 15t – 2t and 2t – 15t.
To determine 15t – 2t is equivalent to 2t – 15t or not.
Substitute t = 2 in above two expressions.
15t – 2t = 15(2) – 2(2)
= 30 – 4
= 26
2t – 15t = 2(2) – 15(2)
= 4 – 30
= –26
The values of the expressions are different when t = 2.
So, 15t – 2t is not equivalent to 2t – 15t.
Hence the expression 15t – 2t not equivalent to 2t – 15t because the negative sign in 15t – 2t belongs to the term 2t.
Answer:
y=-3x+20
Step-by-step explanation:
3/4x+1/4y=5
-3/4x -3/4x
1/4y=5-3/4x
divide the whole entire equation by 1/4 like this: (4)1/4y=4(5-3/4x)
Your answer is y=-3x+20
Answer:
mean = 148
median = 150.5
range = 60
Step-by-step explanation:
mean = sum divided by number of data
median = (n+1)/2
range = highest data-lowest data
