It would be 0 bc
5x-2y=0
then 0+3x=0
So the answer is 0
Hope this helps:)
Answer:
A 16°
B -8°
C 6°
D -16°
E -4°
Step-by-step explanation:
Look at 0° and 10°. There are 5 lines from one to the other, so each line represents 2°.
A
3 lines above 10° = 10° + 3 * 2° = 10° + 6° = 16°
B
1 lines above -10° = -10° + 2° = -8°
C
3 lines above 0° = 0° + 3 * 2° = 0° + 6° = 6°
D
2 lines above -20° = -20° + 2 * 2° = -20° + 4° = -16°
E
3 lines above -10° = -10° + 3 * 2° = -10° + 6° = -4°
Answer:
Step-by-step explanation:
Volume of square pyramid = a^2 x h/3
Volume of pyramid A = 9^2 x 10/3
Volume of pyramid A = 270 cubic inches.
Divide volume of B by A:
1350/270 = 5
5 x 100 = 500 % bigger
To check, rewrite 500% as a decimal and multiply by the volume of A:
500%/100 =5
270 x 5 = 1350
This equals the volume of B, so the scale was calculated correctly.
Sarah bought 3 bracelets and 2 pairs of sunglasses.
Step-by-step explanation:
Total items bought = 5 items
Total spent = $24
Cost of one bracelet = $5
Cost of pair of sunglasses = $4.50
Let,
x be the number of bracelet bought.
y be the number of sunglasses bought.
According to given statement;
x+y=5 Eqn 1
5x+4.50y=24 Eqn 2
Multiplying Eqn 1 by 5
Subtracting Eqn 2 from Eqn 3
Dividing both sides by 0.50
Putting in Eqn 1
Sarah bought 3 bracelets and 2 pairs of sunglasses.
