Answer: x = 40 and y = 40
Step-by-step explanation:
We can write the equation for the area as: x*y = 1600
We can write the equation for the perimeter as: 2x + 2y = 160
An easy way to solve a question like this is to graph both equations on a graphing calculator, if you don't have one on you you can use Desmos
Graph both: y = 1600/x
and
y = 80 - x
Turns out you get x = 40 and y = 40
P < or = 7.
P could be 7, 6, 5, 4, 3, 2, 1, or zero.
Since AB is a straight line, and straight lines are 180 degrees, you can add the two 62 degree angles.
62+62=124
180-124=56
angle x is 56 degrees
Answer:
$5,000
Step-by-step explanation:
First, you have to determine the total amount of money she needs to save to cover the cost of the tuition by subtracting the financial aid, the scholarship and the amount her parents plan to contribute from the total cost of the tuition:
40,000-(40,000/4)-(40,000*25%)-5,000
40,000-10,000-10,000-5,000
40,000-25,000= 15,000
She needs to save a total amount of 15,000. Then, you need to divide this amount by 3:
15,000/3= $5,000
Julieta will need to save $5,000 each year over the next 3 years before her first year.
Answer:
t = 1
Step-by-step explanation:
16 - 2t = 5t + 9
7 = 7t
t = 1
