Answer:
a= 5
Step-by-step explanation:
3 (a-7)= 14-4a -Remove Parentheses
3a-21=14-4a -Move the terms
3a+4a=14+21 -Collect like terms
7a=35 -Divide both sides
a=5 - Solution
Answer:
(C)72.4 in
Step-by-step explanation:
Given an acute triangle in which the longest side measures 30 inches; and the other two sides are congruent.
Consider the attached diagram
AB=BC=x
However to be able to solve for x, we form a right triangle with endpoints A and C.
Since the hypotenuse is always the longest side in a right triangle
Hypotenuse, AC=30 Inches
Using Pythagoras Theorem
Therefore, the smallest possible perimeter of the triangle
Perimeter=2x+30
=2(21.21)+30
=42.42+30
=72.4 Inches (rounded to the nearest tenth)
VictorHesling, your teacher is obviously messing with you. The best thing to do in a situation like this, is give her a messing with you answer. Some suggestions are

Answer:
9 4/9 (this is a mixed fraction btw)
Step-by-step explanation:
Question: 3 4/9 + 5 7/9
Add whole numbers:
3+5 = 8
Combine fractions: 4/9 + 7/9 = 13/9
*fix your improper fraction into a proper one*
so, 13/9 turned into mixed fraction is 1 4/9 (to be clear it's not 14, 1 is the whole number and then the fraction 4/9.) *write it like a mixed fraction please*
anyway, we're not done yet..
8+1 4/9
= 9 4/9
