Answer:
17.25
Step-by-step explanation:
34.50 divided by 2
Option (A)
Given:
Height of Molly is 5 3/4 feet takk.
Height of Andy is 6 1/6 feet takk.
The objective is to find how much taller is Andy than Molly.
The given equation can be wtitten as,
THe difference between their height can be calculated as,
Hence, option (A) is the correct answer.
4x - 7 < 5
Add 7 to the both sides,
4x - 7 + 7 < 5 + 7
4x < 12
Divide 4 from the both sides,
4x/4 < 12/4
x < 3
So, your final answer is x < 3
Hope this helps!
Answer:
Step-by-step explanation:
What he did at the end of the given equations is solve for x in x + 8y= 21
x = 21 - 8y Substitute that result in the top equation.
<u><em>7(21 - 8y) + 5y = 14 </em></u> is the correct step To continue Remove the brackets
147 - 56y + 5y = 14 Combine
147 - 51y = 14 Add 51y to both sides.
147 = 51y + 14 Subtract 14 from both sides.
133 = 51y divide by 51
y = 2.61 rounded.
The incorrect step is <em><u>underlined and italicized.</u></em>
