Francois is paid $52 per day for a job that lasts 4 days. He is paid $67 per day for a different job. Francois earned a total of $610. How many days was he paid $67 per day?
Answer:
6 days
Step-by-step explanation:
$52 per day for 4 days: 4 * $52 = $208
Total pay: $610
Pay for remaining days: $610 - $208 = $402
Number of $67/day days: $402/($67/day) = 6 days
Answer: 6 days
What fraction is shown on the ruler below?
Pls help
Answer:
2 3/8
The denominator is 8 because there are 8 total lines
how you get 2 is because you passed the 2 lines and if you count the lines it goes up to three
complete the statement of each of these rules:
a (+)×(?)=(+)
b (-)×(+)=?
c (?)×(-)=?
Answer:
a) (+) × (?) = (+)
(?) = (+)
b) (-) × (+) = ?
? = (-)
c) (?) × (-) = ?
? is undefined
Step-by-step explanation:
a) (+) × (?) = (+)
From the given equation in the question, by dividing both side of the equation by (+), we have;
((+) × (?))/(+) = (+)/(+)
(?) = (+)/(+) = (+)
Therefore, we have;
(+) × (+) = (+)
(?) = (+)
b) (-) × (+) = ?
From the given equation in the question we apply the operation rules as follows;
(-) × (-) = (+)
(-) × (+) = (-)
Therefore;
(-) × (+) = ? = (-)
? = (-)
c) (?) × (-) = ?
From the rules of multiplication, we have;
(-) × (-) = (+)
(+) × (-) = (-)
Therefore, when (?) = (-), ? = +, from which we have;
(?) ≠ ?, which is an error
Similarly, when (?) = (+), ? = -, therefore, (?) and ?, always changes sign
Therefore, the equation, (?) × (-) = ?, is undefined.

How long is JL?
Answer:
Step-by-step explanation:
2 squartroot 3
The length (JL) of the right-angle triangle will be 1.732 units.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
In the right triangle shown, angle ∠K = 60° and KL is 2. Then the measure of the length JL will be given by the sine the angle ∠K. Then the equation is given as,
JL / KL = sin ∠K
h / 2 = sin 60°
h / 2 = √3 / 2
h = √3
h = 1.732 units
The length (JL) of the right-angle triangle will be 1.732 units.

You roll a number cube. Determine the theoretical probability of rolling a 4 or a 6.
Answer:
Both of them would have a 1/6 chance of being chosen
Step-by-step explanation:
Sorry I don't know if this is the answer you are looking for :(
Answer:
2/6 is read as "2 out of 6" or "2 in 6"
Step-by-step explanation:
Since there are 6 sides on a dice you have a 2 in 6 chance of rolling either a 4 or a 6. The probability of rolling one over the other would be 1/6

Answer:
Step-by-step explanation:
1a. 2x - 4y = 2
-x + 4y = 3
x = 5
-5 + 4y = 3
4y = 8
y = 2
(5, 2)
1b. 2x + 3y=1
-2x + 2y = -6
5y = -5
y = -1
2x - 3 = 1
2x = 4
x = 2
(2, -1)
2a. x + 2y = 4
2x - 5y = -1
-2x - 4y = -8
2x - 5y = -1
-9y = -9
y= 1
2x - 5 = -1
2x = 4
x = 2
(2, 1)
2b. 4x + 2y = 4
x - 2y = -5
5x = -1
x= -1/5
-1/5 - 2y = -5
-2y = -4 4/5
y= 12/5
(-1/5, 12/5)
3. 5x + 3y = 85
11x + 5y = 163
25x + 15y = 425
-33x - 15y = -489
-8x = -64
x = 8 regular

The perimeter of a rectangular area is 16ft.
Write an expression for the sum of the length and width.
Answer:
Length + Width = 8 ft
Step-by-step explanation:
"The perimeter of a rectangle is 16 ft."
A perimeter is the sum of four sides of a rectangle.
OR...
Perimeter = Side 1 + Side 2 + Side 3 + Side 4
A rectangle has "matching sides", so...
Length: Side 1 = Side 3
Width: Side 2 = Side 4
Therefore we can just say that:
Perimeter = (Length * 2) + (Width * 2)
We can pull the 2 out:
Perimeter = 2 * (Length + Width)
Since Perimeter = 18
16 = 2 * (Length + Width)
Divide both sides by 2
8 = Length + Width
Length + Width = 8 ft

BRAINLIST!!! The area of Alex's room is 168 square feet. If his room is a rectangle and one side is 12 feet, how long is the other side.
Write an equation to find the missing length of Alex's room. Let x = missing length in feet
Solve to find the missing length of Alex's room
Answer:
the missing length is 14 feet.
Step-by-step explanation:
a = L × W
168ft² = 12 × W - divide both sides of the equation by 12
- 168 ÷ 12 = 14
168ft² = 12 × 14

(b) O: congruent to 138°
(c) R: supplementary to 32°, 180°-32° = 148°
(d) H: congruent to 32°
(e) S: complementary to 28°, 90° -28° = 62°
(f) O: supplementary to 122°, 180° -122° = 58°
(g) W: congruent to 122°
(h) C: supplementary to 28°, 180° -28° = 152°
(i) I: supplementary to 60°, 180° -60° = 120°
(∠TSW) E: supplementary to a right angle: 180° -90° = 90°
(∠TSU) O: half the complement of 20°, (90° -20°)/2 = 35°

"Evaluation" mostly means "simplifying an expression down to a single numerical value". Sometimes you will be given a numerical expression, wher all you have to do is simplify; that is more of an order-of-operations kind of question. In this lesson, I'll concentrate on the "plug and chug" aspect of evaluation: plugging in values for variables, and "chugging" my way to the simplified answer.
