Step-by-step explanation:
A pint has 2 cups
2 cups = 1 pint
1 cup = 1/2 pint
1/4 cup = 1/2 ÷ 4 = 1/2 * 1/4 = 1/8 pint
Answer:
A numerical coefficient is a constant multiplier of the variables in a term. so it would be 3x cause it has a number and a variable.
a variable is a symbol which functions as a placeholder for varying expression or quantities, so x is the variable.
a constant term is a term in an algebraic expression that has a value that is constant or cannot change, because it does not contain any modifiable variables. so it would be the 2
Step-by-step explanation:
Answer: 2 hr.
Explanation: Think back to rate of change. <em>d</em> = <em>rt</em>, <em>r</em> = <em>d/t</em>, <em>t</em> = <em>d/r</em>. In this case, we will be using <em>d</em> = <em>rt</em>. Mph would be <em>r</em>, rate, so you would categorize 15 mph and 8 mph under rate. <em>t</em> should represent the time each cyclist traveled. Tracey's and Emma's distance, <em>d</em>, would be the same as their mph, hence Tracey's being 15<em>t</em> and Emma's would be 8<em>t</em>. When you add Tracey's distance plus Emma's distance, you end up with 46 mi. Now, you need to combine like terms, which should look like 15<em>t</em> + 8<em>t </em> = 46. Add 15 and 8 to get 23, so it should be 23<em>t</em> = 46 now. Then, divide both sides of the equation by 23 and now you should have your answer, <em>t</em> = 2 hr.
Answer:
y = 5x + 2 . . . . . . . . . . (1)
3x = -y + 10 . . . . . . . . (2)
3x = -(5x + 2) + 10
3x = -5x - 2 + 10
3x + 5x = -2 + 10
8x = 8
x = 1
y = 5(1) + 2 = 5 + 2 = 7
Solution is (1, 7) The answer is (1,7)
Step-by-step explanation:
Given:
The given value is 
.
To find:
The multiplicative inverse of .
Solution:
We know that 
is the multiplicative interval of 
if 
.
Let be the multiplicative inverse of the given value . Then,
Divide both sides by .
Therefore, the multiplicative inverse of is 
. Hence the correct option is A.
