Answer:
4 cans of soup and 2 frozen dinners.
Step-by-step explanation:
Let the can of soup = x
Let frozen dinner s = y
Davis wants to the grocery store and purchased cans of soup and frozen dinners.
Each can of soup has 250 mg of sodium and each frozen dinner has 550 mg of sodium.
David Purchased twice as many cans of soup as frozen dinners and they all collectively contain 2100 mg of sodium.
x = 2y
Hence:
250x + 550y = 2100
250(2y) + 550y = 2100
500y + 550y = 2100
1050y = 2100
y = 2100/1050
y = 2
Since
x = 2y
x = 2 × 2
x = 4
Hence,
the can of soup = x = 4
Let frozen dinner s = y = 2
Davis bought 4 cans of soup and 2 frozen dinners.
Answer:
In bold below.
Step-by-step explanation:
let the shorter leg be x units long, then:
longer leg = x+4
and hypotenuse = x + x + 4 - 8 = 2x - 4 units.
By Pythagoras:
(2x - 4)^2 = x^2 + (x + 4)^2
4x^2 - 16x + 16 = x^2 + x^2 +8x + 16
2x^2 - 24x = 0
2x(x - 12) = 0
x = 12.
So the shorter leg = 12 units
Longer leg = 4 + 12 = 16 units and
Hypotenuse = 12 + 16 - 8 = 20 units.
The first one !!!! Hope this helps
