Answer:
$81
Step-by-step explanation:
9/2 = 4.5
4.5 x 18 = 81
Answer:
D
Step-by-step explanation:
In parallelogram, opposite angles are congruent.
m∠B = m∠D
3x = x + 52 {Subtract x from both sides}
3x - x = 52 {Combine like terms}
2x = 52 {Divide both sides by 2}
x = 52/2
x = 26
m∠B = 3x = 3*26 = 78
Answer: x=3 y=3
Step-by-step explanation:
Assuming you meant 2x+3y=15 as the first problem. You have to make either both the x’s or both the y’all equal in both equations first. Multiply the second equation by 2 (for x’s) and you’ll get 2x+2y=12. The 2x cancels out so you’re left with 3y=15 and 2y=12. Subtract 2y=12 from 3y=15 and you get y=3.
Repeat to figure out x. Multiple second equation by 3 (for equal y’s) and you get 3x+3y=18. This time the first equation is being subtracted from the second one. (3x+3y=18) - (2x+3y=15). Y’s cancel out and you’re left with (3x=18)-(2x=15. Subtract and you get x=3
Answer: it dose not show anything
Step-by-step explanation:
Assuming the question is : Choose a height for the line
Cubic = Volume, we can square root this 3 times to get ONE possible number that could be multiplied to make the volume
One possible height for the line could be, 10.16 inches (2 DP)
