in a sale, the normal price of a hat is reduced by 15%
The sale price of the hat is 20.40 euros.
Work out the normal price of the hat.
Answer:
The correct answer is 24
Step-by-step explanation:
To solve this math problem, you will need to divide 20.40 with 1 (1 is 100% as a decimal) and 0.15 (0.15 is 15% as a decimal).
--
[tex]20.40[/tex] ÷ [tex](1-0.15)[/tex]
--
First, subtract 1 and 0.15
[tex]1-0.15=0.85[/tex]
Next, divide 20.40 and 0.85
[tex]20.40[/tex] ÷ [tex]0.85 = 24[/tex]
--
Therefore, the final product of this math problem is 24
Q. Which of these represents stope-intercept form of a linear equation?
answer choices
A)Ax+By=c
B)y-yı = m-x)
C)y=kx
D)y=mx + b
Answer:
D
Step-by-step explanation:
this is so easy just plug the question in
Answer:
D.y= mx + b
Step-by-step explanation:
Slope-intercept is a specific form of linear equations. It has the following general structure
y= mx + b
Here, m can be any two real numbers. For example, these are linear equations in slope-intercept form:
y=2x+1
y=-3x+2.7y
y=10-100x
On the other hand, these linear equations are not in slope-intercept form:
2x+3y=5
y-3=2(x-1)y−3=2(x−1)
x=4y−7
Slope-intercept is the most prominent form of linear equations
Need answers to all quick
1) Slope = 6 and y-intercept (0, -2)
2) Slope = 2/3 and y - intercept (0, 5)
3) Slope = -5 and y - intercept (0, 0)
4) Slope = 0 and y - intercept (0, -1)
5) Slope = -1 and y - intercept (0, 4)
Answer:
See explanation
Step-by-step explanation:
For any line, with slope [tex]m[/tex] and y-intercept [tex](0, b)[/tex] the line is [tex]y=mx+b[/tex].

If 53 sweets get shared between 6 children,how many will be left over?
Please give details to them all I’m not very smart lol
Answer:
Step-by-step explanation:
For number 8, to start,:
[tex]\frac{x}{4}[/tex] - 1 = 1
the first step is to add 1 to both sides of the equation; then, simplify.
[tex]\frac{x}{4}[/tex] - 1 = 1
+1 +1
----------------
next, the -1 and +1 will cancel.
[tex]\frac{x}{4}[/tex] = 2
the last step is to multiply both sides of the equation by 4.
4 · [tex]\frac{x}{4}[/tex] = 2 · 4
simplify; the 4s cancel out on the left side.
x = 8
**************************************************
For number 9, :
9 = 6 + [tex]\frac{x}{7}[/tex]
like in number 8, the first step is to subtract 6 from both sides of the equation; also, a helpful tip you can use is move the 9 to the right side; speaking personally, it often helps make things visually easier to work out. you would then rewrite the equation like: 6 + [tex]\frac{x}{7}[/tex] = 9
6 + [tex]\frac{x}{7}[/tex] = 9
now, we'd subtract 6 from both sides.
6 + [tex]\frac{x}{7}[/tex] = 9
-6 -6
-----------------
next, the 6 and -6 will cancel.
[tex]\frac{x}{7}[/tex] = 3
the last step is to multiply both sides of the equation by 7.
7 · [tex]\frac{x}{7}[/tex] = 3 · 7
simplify; the 7s cancel out on the left side.
x = 21
Select the correct answer.
Answer:
B. x = -5
Step-by-step explanation:
-8(x+5) = -3x - 7 + x - 3
distribute the -8
-8x - 40 = -3x - 7 + x - 3
combine like terms
-8x - 40 = -2x - 10
add 40 to both sides
-8x = -2x + 30
add 2x to both sides
-6x = 30
divide both sides by -6
x = -5

∠A and \angle B∠B are complementary angles. If m\angle A=(7x+23)^{\circ}∠A=(7x+23)
∘
and m\angle B=(5x+19)^{\circ}∠B=(5x+19)
∘
, then find the measure of \angle B∠B.
Since there are complementary angles, the value of angle B is 39°.
Angle A = 7x + 23°
Angle B = 5x + 19°
It should be noted that the total angles in a complementary angle are equal to 90°.
Therefore, we need to add angle A and B together and then equate them to 90°. This will be:
7x + 23° + 5x + 19° = 90°
Collect like terms
12x + 42° = 90°
12x = 90° - 42°
12x = 48°
x = 48°/12
x = 4°
Angle A = 7x + 23° = 7(4) + 23° = 28° + 23° = 51°
Angle B = 5x + 19° = 5(4) + 19° = 20° + 19° = 39°
The value of angle B is 39°.

We can calculate the total price in dollars (d) based on the pounds of ribeye steak (s) sold using the equation d=8s. What would be the total price (d) of 4 pounds of steak?
Answer:
$32
Step-by-step explanation:
The variables in this equation are already defined. So we know that whatever d is equal to will be the cost, and therefore, the final answer. Additionally, s is the number of pounds of steak, so it is an independent variable. To solve this equation, plug in the number of pounds, 4, into the equation for s. Also, 8 is the unit price for the steak, so this multiplied by the amount of steak must be the total cost. This makes the new equation, d=8(4). Finally, multiply these numbers to get d=32. So the final cost for 4 pounds of steak must be $32.
Answer:
32 dollars
Step-by-step explanation:
The Equation to calculate the total price(d) based on the pounds of ribeye steak(s) sold if given as:
d = 8S
So, to calculate the total price(d) of 4 pounds of steak, all we need do is to substitute 4 into the given formula
That is,
d = 8(4)
d = 32 dollars
Therefore the price of 4 pounds of steaks is 32 dollars
