We can use substitution method to solve for this system of equations. We calculate as follows:
<span>2x – 6y = –14
-6y = -14 -2x
y = x/3 + 7/3
</span>5x – 3y = –11
5x – 3(x/3 + 7/3) = –11
5x - x + 7 = -11
4x = -11 -7
4x = -18
x = -9/2
y = -9/2(3) + 7/3
y = 5/6
Answer:
False
Step-by-step explanation:
Answer: x=12
Step-by-step explanation:
yes because you must find the product of 3 and 2 so you can then and 8 to it
Answer:
Step-by-step explanation:
<u>Surface area:</u>
- S = 2(lw + lh + wh) + 2πrh
- S = 2(9*4 + 9*5 + 4*5) + 2*3.14*2*3 = 239.7 cm² (rounded)
<u>Volume:</u>
- V = lwh + πr²h
- V = 9*4*5 + 3.14*2²*3 = 217.7 cm³ (rounded)
