Answer:
The expressions that are equivalent are <u>A</u>, <u>D</u>, and <u>E</u>.
Step-by-step explanation:
Given:
-7z+ ( - 6.5) + 3.5z + 6y - 1.5.
On solving the equation:
![-7z+ ( - 6.5) + 3.5z + 6y - 1.5](https://tex.z-dn.net/?f=-7z%2B%20%28%20-%206.5%29%20%2B%203.5z%20%2B%206y%20-%201.5)
![-7z - 6.5+ 3.5z + 6y - 1.5](https://tex.z-dn.net/?f=-7z%20-%206.5%2B%203.5z%20%2B%206y%20-%201.5)
![-7z + 3.5z + 6y - 1.5-6.5](https://tex.z-dn.net/?f=-7z%20%20%2B%203.5z%20%2B%206y%20-%201.5-6.5)
![-3.5z+6y-8](https://tex.z-dn.net/?f=-3.5z%2B6y-8)
So, on solving the equation we get the expression:
![-3.5z+6y-8](https://tex.z-dn.net/?f=-3.5z%2B6y-8)
<em>According to question:</em>
<em>We see that expressions:</em>
A. ![-8+6y+(-3.5z)](https://tex.z-dn.net/?f=-8%2B6y%2B%28-3.5z%29)
![=-8+6y-3.5z = 3.5z+6y-8](https://tex.z-dn.net/?f=%3D-8%2B6y-3.5z%20%3D%203.5z%2B6y-8)
So, this expression is equivalent.
D. ![6y-8-3.5z](https://tex.z-dn.net/?f=6y-8-3.5z)
So, this expression is also equivalent.
E. ![-3.5z+6y-8](https://tex.z-dn.net/?f=-3.5z%2B6y-8)
So, this expression is also equivalent.
Therefore, the expressions that are equivalent are A, D, and E.
Answer: 20 weeks
Step-by-step explanation:
12,500- 2,500= 10,000
10,000 x .25= 2,500
2,500= 125x
2,500/125= 20
Answer:
Answer is A - (1, 3) and (2, 6)
Step-by-step explanation:
(1, 3) • 2
= (1 • 2, 3 • 2)
= (2, 6)
Ratio: 2/2, 6/2
Therefore, the answer is A.
Answer:
a1 =a1+(n-1) *d =8+(1-1)*9=8
a2 =a2+(n-1) *d =8+(2-1)*9=17
a3 = a3+(n-1) *d =8+(3-1)*9=26
Sana po makatulong :)
