Answer:
-21 = 6t
Step-by-step explanation:
3t - 7 = 5t
Subtract 3t from each side
3t-7-3t = 5t-3t
-7 = 2t
Multiply each side by 3 to get 6t
-7*3 = 2t*3
-21 = 6t
Answer: 1/2
Step-by-step explanation: 1 x 3 = 3 and 2 x 3 = 6
Answer:
Cup A
Step-by-step explanation:
<u>Cup A</u>
Salt: Water = 3:22
Expressed as a percentage
Proportion of Salt =13.6%
<u>Cup B</u>
Salt: Water = 1:8
Expressed as a percentage
Proportion of Salt =12.5%
<u>Cup C</u>
Proportion of Salt = 12.75%
Therefore, Cup A has the greatest proportion of salt.
Answer:
30.5 cm
Step-by-step explanation:
0 < h ≤ 10 ⇔ Midpoint = 5
10 < h ≤ 20 ⇔ Midpoint = 15
20 < h ≤ 30 ⇔ Midpoint = 25
30 < h ≤ 40 ⇔ Midpoint = 35
40 < h ≤ 50 ⇔ Midpoint = 45
50 < h ≤ 60 ⇔ Midpoint = 55
<u>⇒ </u><u><em>Multiply each corresponding midpoint with it's frequency</em></u>
(5 × 1) + (15 × 4) + (25 × 7) + (35 × 2) + (45 × 3) + (55 × 3) = 610
<u>⇒ </u><u><em>Divide the total of 610 by the frequencies added together</em></u>
610 ÷ (1 + 4 + 7 + 2 + 3 + 3) = 610 ÷ 20 = 30.5
We need to see the table in order to answer the question
