Answer:
35 units
Step-by-step explanation:
Using Pythagoras Thereoem:
a² + b² = c²
21² + 28² = c²
c = √21² + 28² = √441 + 784 = √1,225 = 35 units
Answer:
C. 1/2
There are many ways to do this but I'll use substitution.
Step-by-step explanation:
Bottom equation yields x = 4 - 8y
plug that into the top equation results in:
4(4 - 8y) - y = 3y + 7
Simplify this to find y:
-36y = -9
y = 1/4
Plug that into the bottom equation we get:
x = 4 - 2 = 2
Thus, xy = 2(1/4) = 1/2 (C)
Answer:
6n^2z is the greatest common factor
Answer:7 ounces
Step-by-step explanation:
If they charge 0.50 cents per ounce then u would take the 50 cents and add that up until it gets to 3.50 and that will give u 7 so the answer is 7 ounces.
Answer:
y = 4/3x - 2, B is your answer
Step-by-step explanation:
Y intercept is the number next to slope(b).
The co efficient of x will be your slope so therefore the co efficient of x will be 4/3
y is always there because it will always be the dependent variable on the left side.
