Answer: Let's simplify step-by-step.
3x−2
There are no like terms.
So it going to be the same, =3x-2
Step-by-step explanation: hope you understand
6m-3k²
= 6(7) - 3 (2)²
= 42 - 3(4)
= 42 - 12
= 30
m + | 2m-k|
7 + | 2(7) - 2|
7 + | 14-2|
7 + 12
= 19
Answer:
27 < 5*n +7
n<4
Step-by-step explanation:
Twenty-seven is smaller than five times a number increased by seven
Increase means add
27 < 5*n +7
Subtract 7 from each side
27-7 <5n+7-7
20 < 5n
Divide by 5
20/5 < 5n/5
4 <n
B because first you do the two triangles which =3 then you get the area for the square in the middle which is 15 then you add them up to get 18
(Original Price $425.4)
$328 × 30% = 98.4
328 + 98.4 = $426.40
