Answer: -14
Step-by-step explanation: Here we're asked to simplify -|-14| so we
start by simplifying the absolute value of -14.
Remember that the absolute value of
any positive or negative integer is positive.
So the absolute value of -14 is 14.
So we write (14) in parenthses like I have just done.
Next, we bring down the negative sign
that was outside the absolute value.
So we're left with -(14) or -14.
Answer:
There would be 30 nickels and 78 quarters.
Step-by-step explanation:
To find this, start by creating a system of equations in which x is the number of nickels and y is the number of quarters. Make the first equation the total number of coins.
x + y = 108
Make the second equation based on the value.
.05x + .25y = 21
Now multiply the second equation by -4 and add together to get the y value to cancel.
x + y = 108
-.2x - y = -84
--------------------
.8x = 24
x = 30
Now use this value to find y.
x + y = 108
30 + y = 108
y = 78
Answer:
Keith scored 70% on the History test.
Step-by-step explanation:
We have been given that for History test, Keith had to answer 40 questions. Of these 40 questions, Keith answered 28 of them correctly.
To find the percentage Keith got on History test, we will have to figure out 28 is what percent of 40.
Therefore, Keith scored 70% on the History test.
50 cm = 1/2 m
3 m ÷ 1/2 m = 6
It will take him six days.
Answer:
This is an exponential function
Step-by-step explanation:
f(x)=2(3)^x is one example of the exponential function. Since f(0) = 2(1) = 2, the y-intercept is (0, 2). The x-axis is the horizontal asymptote. The graph begins in Quadrant II, passes through (0, 2) and continues to increase, faster and faster, in Quadrant I. Next time, please be more specific about what you'd like to know.
