5. 114 ounces .
Explaination : ONE pound is 16 ounces . 7 pounds would be 112. add 112 plus the 2 ounces = 114 ounces
6. a. FALSE, 4 kilograms is 4,000 grams
b. TRUE , 10 yards = 360 inches
c. FALSE , 10 liters = 10,000 milliliters
Answer:
1+1=2-1=1
Step-by-step explanation:
lol, this is the hardest question I've done today.
4x - 5y = -12
-x + 5y = 18
Add the equations together:
4x + -x = 3x
-5y + 5y = 0
-12 + 18 = 6
So now you have:
3x = 6
Divide both sides by 3:
X = 2
Now you have the value of x, replace x with 2 in one of the equations and solve for y:
4(2) -5y = -12
8 -5y = -12
Subtract 8 from both sides:
-5y = -20
Divide both sides by -5:
Y = 4
The solution is x = 2 and y = 4 which is written as (2,4)
The slope is 0 the equation of the line is y=3
