Manuel earns 5350 a month. if he worked eight hours a day for 20 days, how much did he make each hour? Express your answer in dollars and cents. (Rounded)
Answer:
$33.44Step-by-step explanation:
Working hours:
20 days, 8 hours a day20*8 = 160 hoursEarning in a month = $5350
Hourly earning rate:
5350/160 = 33.4375 = $33.44 roundedShow steps of how to factor (3x^2 + 5xy - 2y^2)
(3x² + 5xy - 2y²)
3x² + 5xy - 2y² (rewrite the expression) (write 5xy as a difference)
3x² + 6xy - xy - 2y² (factor the expression) (factor out 2x from the expression)
3x x (x + 2y) -y x (x + 2y) (factor the expression) (factor out x + 2y from the expression)
Solution : (x + 2y) x (3x - y)
Change -3x+3y=9 into slope intercept form
To convert to slope-intercept form, we need to get the y by itself.
First add 3x to both sides to get 3y = 3x + 9.
I put the x term first because in slope-intercept form or y = mx + b form,
the x term will always come before the constant term.
Now divide both sides by 3 to get y = x + 3.
Answer:
y = x + 3
Step-by-step explanation:
-3x + 3y = 9
3y = 9 - 3x
/3 /3 /3
y = x + 3

Which expression is equivalent to 1.8(2x + 7) - 15?
a 1.2x
b 3.6x - 2.4
0 3.6x - 8
d 16.2x - 15
Answer:
Option B. 1.8(2x + 7) – 15 = 3.6x – 2.4
Step-by-step explanation:
1.8(2x + 7) – 15
To know which option is correct, let us simplify the above expression. This can be obtained as follow:
1.8(2x + 7) – 15
Clear bracket
1.8(2x + 7) – 15 = 3.6x + 12.6 – 15
1.8(2x + 7) – 15 = 3.6x – 2.4
Thus,
1.8(2x + 7) – 15 is equivalent to
3.6x – 2.4

Help me pleaseee I don’t understand
I'll solve one from each kind
Q1)
6 = a/4 + 2 (mutiply both sides)
24 = a + 8 (move the terms)
-a = 8 - 24 (calculate)
-a = 8 - 16 (change the signs)
a = 16
Q8)
2( 2 + 5) = -2 (divide both sides)
n + 5 = -1 (move the constant to the right)
n = -1 - 5 (calculate)
n= -6
Q3)
9x - 7 = 7 (cancel equal terms)
9x = 0 (divide both sides)
x = 0

Diego bought some raisins and walnuts to make trail mix. Raisins cost $4 a
pound and walnuts cost $8 a pound. Diego spent $30 on both ingredients.
Write an equation to represent this constraint. Let x be pounds of raisins
and y be pounds of walnuts.
Answer:
4x + 8y = 30
Step-by-step explanation:
Cost of raisins = $4 per pounds
Cost of walnuts = $8 per pounds
Total spent on both ingredients = $30
Let
Pounds of raisins = x
Pounds of walnuts = y
Diego's equation can be represented by
PxQx + PyQy = 30
Where,
Px = price of raisins
Qx = Quantity of raisins (pounds)
Py = price of walnuts
Qy = Quantity of walnuts (pounds)
PxQx + PyQy = 30
4x + 8y = 30
i need < 2 and <4 help plz
Answer:
Step-by-step explanation:
m<3 = 43 degrees
add 43 degrees and 43 degrees and the answer is 86. and since everything equals 180 degrees, 180 - 86 = 94. since there are 2 side needed to be solved divide 94/2 = 47
so 47 degrees for <2 and 47 degrees for <4
to check my work just add up all the sides
47 degrees for <2, 47 degrees for <4, 43 degrees for <1, 43 degrees for <3
47 + 47+ 43+ 43= 180 degrees
hope this helps:)
what is the expression: the quantity n minus 6 cubed? (in algebraic expression)
Answer:
The equation is either n-6^3 (this is without cubing the 6, this is probably what your teacher is looking for.) or n-216 (this is what the equation looks like when 6 is cubed)

Does 1/6, -3, V7, -6/5 or 4.5 come first when the numbers are listed from least to greatest? Explain.
Answer:
-3
Step-by-step explanation:
Given numbers:
1/6, -3, √7, -6/5, 4.5
The smallest one is chosen between the two negatives as all the rest are greater.
- 3 is smaller than - 6/5= -1.2 as 3 > 1.2So the answer is -3
Greetings from Brasil...
Let's look at each number
1/6 = 1 ÷ 6 = 0.16666....
- 3 = - 3
√7:
√4 < √7 < √9, so
2 < √7 < 3 the result of √7 is between 2 and 3
-6/5 = (- 6) ÷ 5 or 6 ÷ (- 5) = - 1.2
4.5 = 4.5
Writing the numbers in ascending order can tell:
- 3; - 6/5; 1/6; √7 and 4.5or (same values - approximated values):
- 3; - 1.2; 0.2; 2.5 and 4.5
see annex
What should happen to both sides of the equation to isolate the variable?
Answer:
If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. When you solve an equation, you find the value of the variable that makes the equation true. In order to solve the equation, you isolate the variable
