Answer:
(25 * 5.5) + (x * 2.9) + [(25 - x) * 4.4] = 50 * 4.5
Step-by-step explanation:
0.5 * 50Lbs. = 25 Lbs.
12.5 Lbs
12.5 Lbs.
Answer:
(25 * 5.5) + (x * 2.9) + [(25 - x) * 4.4] = 50 * 4.5
stacey made 8 necklaces in 48 minutes. nick made 4 necklaces in 24 minutes. is the rate at which they made necklaces equivalent. explain the reasonsing
Answer:
Yes.
Step-by-step explanation:

What is the value of the 24th term in the following arithmetic sequence?
-9, -2, 5, 12, ...
A. -170
B. 152
C. -200
D. 170
Answer:
Option B
Step-by-step explanation:
[tex]a_{n}=a_{1} +d(n-1)\\a_{n}=-9 +7(n-1)\\a_{24}=-9 +7(24-1)\\a_{24}=-9 +7(23)\\a_{24}=-9 + (161)\\\\a_{24}=152\\[/tex]
a=-9
d=-2-(-9)
= 7
d= 5-(-2)
= 5+2
=7
a24 = a+23d
= -9 + 23×7
= -9 + 161
a24 = 152
so, answer is b.152

Maritza hiked 6 miles in 2 hours. At this same rate, what is the total number of miles Maritza could hike in 9 hours?
Answer:
27 miles

HELP! BRAINLEST IF STEP BY STEP SO I CAN UNDERSTAND
Answer:
Step-by-step explanation:
lets start here:
we can do 7x4=28
but we can't do 7x5, because 7x5 is 35, which is bigger than 34
so, you do 34 - 28 which gives you 6, and 6 is smaller than 7 so we can't subtract 6- a bigger number! so its 4 R 6!
hope this helped!
