Answer:
7.6-5.2n
Step-by-step explanation:
combine like terms so -3.2n-2n = -5.2n
2.6+5=7.6
7.6-5.2n
Answer:
-5.2n + 7.6
Explanation:
2.6 - 3.2n - 2n + 5
Add Similar Elements-3.2n - 2n = -5.2n= 2.6 - 5.2n + 5
Add2.6 + 5 = 7.6= -5.2n + 7.6

A cashier will randomly choose two coins one at a time without replacement. What is the probabilty that the cashier will chose a penny first, followed by a dime?
Complete question is;
A cash register contains coins. 10 pennies, 11 nickels, 13 dimes, and 6 quarters. A cashier will randomly choose two coins one at a time without replacement. What is the probability that the cashier will choose a penny first, followed by a dime?
Answer:
1/12
Step-by-step explanation:
We are told there are 10 pennies, 11 nickels, 13 dimes, and 6 quarters.
Thus total number of coins = 10 + 11 + 13 + 6 = 40 coins
Probability of picking a penny first is;
10/40 = 1/4
After which we will have 39 coins left.
Probability of a dime after that will be 13/39 = 1/3
Thus,probability of picking a penny first then a dime will be; ¼ × ⅓ = 1/12

Answer:
$546.25 is the total pay for that week
Step-by-step explanation:
Allen makes $11.50 per hour. That means that if he works 40 hours per week, he will make 460$.
$11.50 * 40 hours = $460 per week
Overtime is any number of hours he works over 40 hours per week. Allen makes 50% more for every hour of overtime. Instead of making 11.50, he will be making $17.25.
$11.50 * 1.5 = $17.25 per hour of overtime
--------------------------------------------------------------------------------------------------------------
To solve the problem:
1. How many hours were worked total on that particular week?
2. How many hours were normal time, how many were overtime?
3. Multiply normal time hours by $11.50, overtime hours by $17.25.
4. Add them together for the total compensation
Solution:
The week of 5/17, Allen worked 45 hours total. This is 40 hours of normal time, 5 hours of overtime.
40 hours * $11.50 = $460.00
5 OT hours * $17.25 = $86.25
$460.00 + $86.25 = $546.25 is the total amount earned that week.

Wren is at the grocery store buying fruit. She buys x pounds of apples for $1.68 per pound. She buys 2 fewer pounds of grapes for $2.48 per pound. The cost of the fruit, before tax, is $13.76. How many pounds of each fruit is she buying?
Answer:
The number of pounds of apples is 4.5 and the number of pounds of grapes is 2.5
Step-by-step explanation:
Let
x ------> the number of pounds of apples
(x-2) -----> the number of pounds of grapes
we know that
Solve for x
so
therefore
The number of pounds of apples is 4.5 and the number of pounds of grapes is 2.5
Answer:
4.5 pounds of apples
2.5 pounds of grapes
Step-by-step explanation:
a = # of apples
(a - 2) = # of grapes
1.68a + 2.48(a - 2) = 13.76
1.68a + 2.48a - 4.96 = 13.76
4.16a = 18.72
a = 4.5; Apples
(a - 2) = 2.5; Grapes

Solve 1.1(3.4x-2.3)^2=15.5 and write it in ax^2+bx+c=0 form.
Answer:
In the normal ax² + bx + c format, this equation is expressed as:
12.716x² - 17.204x + 9.81 = 0
If we solve for x, it is approximately equal to both 178 and -0.43
Step-by-step explanation:
Let's reformat to ax² + bx + c = 0:
[tex]1.1(3.4x - 2.3)^2 = 15.5\\1.1(11.56x^2 - 15.64x + 5.29) = 15.5\\12.716x^2 - 17.204x + 5.819 = 15.5\\12.716x^2 - 17.204x + 9.81 = 0\\[/tex]
And now let's find the value of x
[tex]1.1(3.4x - 2.3)^2 = 15.5\\(3.4x - 2.3)^2 = 15.5 / 1.1\\(3.4x - 2.3)^2 = 14.09\\3.4x - 2.3 = \sqrt{14.09}\\3.4x = 2.3 \pm \sqrt{14.09}\\x = \frac{2.3 \pm 3.75}{3.4}\\x = (1.78, -0.43)[/tex]
Answer:
12.716x^2 -17.204x -9.681=0
Step-by-step explanation:
Is √64 a rational or irrational
Is the square root of 64 rational or irrational? The square root of 64 is a rational number if 64 is a perfect square. It is an irrational number if it is not a perfect square. Since 64 is a perfect square, it is rational number. This means that the answer to "the square root of 64?" will have no decimals. √ 64 is a rational number
simple version:yes its rational

Write the equation of the line in fully simplified slope-intercept form.
Answer:
y=-1/2 x-4
Step-by-step explanation:
y=mx+c
c is -4
m is rise/run so -1/2
3(x-2) + 1 = 2(x-4) + x + 13
3(x - 2) + 1 = 2(x - 4) + x + 13
3x - 6 + 1 = 2x - 8 + x + 13
3x + 7 = 3x + 5
3x + 7 = 3x + 5
