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 roundedHow do you write 3.8 in scientific notation?
Answer:
3.8 × 10^{1}
Step-by-step explanation:
Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10b.
Follow the steps below to see how 38 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 38
New Number: 3.8
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 3 . 8
Decimal Count: 1
There are 1 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 3.8
b = 1
Now the whole thing:
3.8 x 10^{1}
Step 4
Check work:
10^{1} = 10 x 3.8 = 38
8 − a = 17. What does a equal?
Answer:
a = -9
Step-by-step explanation:
8 - a = 17
8 -17 = a
-9 = a
Answer:
-9
Step-by-step explanation:
subtract 8 from both sides. divide -1 by both sides it gives you -9. When put into the equation the two negatives make a positive and you add 8 + 9 which gives u 17.

Step-by-step explanation:
Zane is washing cars to help pay for a school trip. He gets paid $8 for every car he washes and made a total of $64 on Saturday. Write an equation to show how many cars Zane washed on Saturday.
8 − x = 64
64x = 8
8 + x = 64
8x = 64
Answer:
I just to the test
It D: 8x=64
Answer:
D: 8x = 64
Step-by-step explanation:
($8) equals the amount he makes for washing 1 car
($64) is the total amount Zane has made from washing cars
(X) is equal to how many cars he has washed for the total to be $64
Now, all we have to do is write down an equation that shows how we can find how many cars have been washed for him to get his sum of $64.
8 times x (x is equal to the number of cars he's washed) so 8 times something (or x) gives you the amount of money Zane has made which would be the only viable answer to the question.
8 - x = 64 - Incorrect
You would not be subtracting the amount of cars Zane has washed by the amount of money he is making per car.
64x = 8 - incorrect
This would mean you're multiplying the total amount of money Zane has made, by how many cars he's washed, which then equals the amount he makes per car. Doesn't make sense ik.
8 + x = 64 - incorrect
While this could look like a viable answer to what they're asking, don't be tricked. You have to multiply the number of cars Zane has washed by the amount he makes per car, otherwise you would just be adding 8 plus the number of cars he washed which does not equal $64.

2x/x-5 = 4 (solve this equation)
If possible, do please tell me on how to do these kind of questions! <3
Answer:
x=10
Step-by-step explanation:
(2x)/(x-5)=4
first you multiply the denominator on both sides
2x=4(x-5)
then multiply
2x=4x-20
then move all the x variables to one side and the constants to the other with subtraction and addition
20=2x
divide and you get x=10
you can plug this in to check your work and you'll see: (2(10))/(10-5)=4 or 20/5=4 which you know is true

The m∠B is two more than three times the measure of ∠C. If ∠B and ∠C are complementary angles, find the measures of both angles.
Answer:
m∠B= 67
m∠C= 23
Step-by-step explanation:
okay so same thing we did before except they will equal 90 not 180
B= 3(c)+2
c+b=90
c+3(c)+2=90
4c+2=90
4c=92
c=23
now input them! or subtract!
90-23=67
m∠C=23
m∠B=67

as 1-2 (-2) < 8
1+ 4 < 8
5 < 8 satisfies the given equation
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

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

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
