One <u>possible inequality</u> is:
299m+261j ≥ 1000.
Explanation:
m is the number of cups of milk and j is the number of cups of juice.
Each cup of milk contains 299 mg of calcium. This gives us 299m mg of calcium for m cups of milk drank.
Each cup of juice contains 261 mg of calcium. This gives us 261j mg of calcium for j cups of juice drank.
Together, this would be a total of 299m+261j mg of calcium.
We want to meet or exceed 1000 mg of calcium. This means we could have more than 1000 or equal to 1000; this gives us the inequality symbol "greater than or equal to":
299m+261j ≥ 1000
Answer:
365
Step-by-step explanation:
The discount is 30 %
That means we pay 70 %
original price * 70% = 255.50
Change to decimal form
original price * .70 = 255.50
divide each side by .70
original price * .70/.70 = 255.50/.70
original price =365
Idk tbh I think you can search that up
Answer:
Step-by-step explanation:
Plot that point in the x/y coordinate plane to see that it sits in the third quadrant. From the point, draw a line to the origin, constructing a right triangle. The side adjacent to the angle is -2, the side across from the angle is -5, so we need to find the length of the hypotenuse using Pythagorean's Theorem:
and
so
That means that
and
That means that
and
It also means that
