Answer:

Step-by-step explanation:
You only need to isolate the term a to solve this problem.
Add by 3 from both sides.

Solve.
0+3=3
a/7<3
Multiply by 7 from both sides.

Solve.
3*7=21
<u>a<21</u>
As a result, the solution is a<21, which is our answer.
42/3=14 (price of one shirt) 100-20=80 (robert buys 5 shirt each costing 80% of the original price) 14/100x80=11.20 (price of one shirt with a 20% discount) 11.20x5=56 cost of all 5 shirts
y = mx + b, where m = slope, and b = y-intercept.
Since you are not given the y-intercept, you have to solve for it through the equation, y = (4/5)x (which is the slope you are given) + b, and replace x and y with values given, which are (-5,-3)
y = (4/5)x + b
-3 = (4/5)(-5) + b
-3 = -4 + b
1 = b
Then replace b in the first equation to get the answer
y = (4/5)x + 1

Answer:
the right answer is rectangle
Step-by-step explanation:
Compare the pairs of sides. One pair measures 4 inches, but the other pair does not and forms 90 ° angles. This figure does not have its four congruent sides, so it is a rectangle.
