Answer:
im not the best at algebra but
2a+3b+4c
Step-by-step explanation:
subtract
(2a−3b+4c) from the sum of (a+3b−4c),(4a−b+9c) and (−2b+3c−a).
add
=(a+3b−4c)+(4a−b+9c)+(−2b+3c−a)
=(a+4a−a)+(3b−b−2b)+(−4c+9c+3c)
=4a+8c
then subtract
=(4a+8c)−(2a−3b+4c)
=4a+8c−2a+3b−4c
=2a+3b+4c
Answer:
b=2/3
Step-by-step explanation:
The table is given as:

The exponential function is given in the form

where a is the initial value and b is the multiplicative rate of change
When x=1, y=9, we have:

When x=3, y=4, we have:

Dividing the two equations:

The multiplicative rate of change, b is 2/3.
Answer: Abigail can make about 16 candles because 0.4 of a candle would not make an entire candle.
Step-by-step explanation:
For the Wax, it’s
V=Bh
V= l*w*h
= 15 cm * 11cm * 18 cm
= 2,970 cm^3
For the Mold, it’s
V=Bh
= r^2h
= * (3.1 cm)^2 * 6
= about 181 cm^3
Then you divide to find out how many candles you can make.
2,970 cm^3/181= 16.4
Hope this helps!
3. 1*2* 1/3= 2/3 yd
4. 1/4 * 1/8 *2= 1/16in
6. 12 *4= 48ft
the numbers on the sides are the length, width and height. you multiply them all together to find the volume
