1[tex]\frac{2}{5}[/tex] ÷ [tex]\frac{1}{3}[/tex]
Divide [tex]\frac{1 x 5+2}{5}[/tex] by [tex]\frac{1}{3}[/tex] by multiplying [tex]\frac{1 x 5+2}{5}[/tex] by the reciprocal of [tex]\frac{1}{3}[/tex]
[tex]\frac{( 1 x 5 + 2) x 3}{5}[/tex]
Add 5 and 2 to get 7.
[tex]\frac{7 x 3}{5}[/tex]
Multiply 7 and 3 to get 21.

Answer:
19, 18, 15.5
Step-by-step explanation:
To solve this problem, you need to substitute the given values into the function.
b(x = -2) = 18 - 0.5(-2) = 18 + 1 = 19
b(x = 0) = 18 - 0.5(0) = 18 - 0 = 18
b(x = 5 ) = 18 - 0.5(5) = 18 - 2.5 = 15.5
Please include working out. =D You will get 30 points for it.
Answer:
It should be c
Step-by-step explanation:
Your formula is
Number of color ball/total ball
so 8/20 x 7/19 x 3/18 then convert to fraction
The probability the first ball is red is 0.4 or 8/20 or 2/5
The probability the next is blue is 7/19
The probability of the next being white is 6/18 or 1/3.
Multiply them together because these are independent events that must all occur and we get 2*7*1= 14 as the numerator
5*19*3=285 for a total probability of 14/285.

$40-$10= $30.00
Answer:
The dress' price is $30.
Step-by-step explanation:
The discount on the dress is for 25% off.
25% of $40, is $10.
$40 - $10 is $30, resulting in a sale price of $30.

the sum of three numbers is 20
the first is 4 times the sum of the other two
the second is seven times the third
what is the product of all three
Answer:
A*B*C= 28
Step-by-step explanation:
A+B+C=20
1. A = 4(B+C)
2. B = 7C
3. C = C
----------------------
1.
A = 4( 7C + C )
A=4(8C)
A= 32C
---------------------
A+B+C=20
32C + 7C + C = 20
40C = 20
C = 20/40
C = 1/2
------------------------
A= 32(1/2) = 32/2 = 16
B= 7(1/2) = 7/2
C= 1/2
A*B*C = 16 * 7/2 * 1/2
A*B*C= 28

The graph of [tex]y = \frac 34x +5[/tex] has a slope of 3/4 and a y-intercept of 5
The linear equation is given as:
[tex]y = \frac 34x +5[/tex]
Set x = 0
[tex]y = \frac 34 * 0 +5 = 5[/tex]
Set x = 1
[tex]y = \frac 34 * 1 +5 = 5\frac 34[/tex]
Set x = 2
[tex]y = \frac 34 * 2 +5 = 6\frac 12[/tex]
The above means that, the graph of [tex]y = \frac 34x +5[/tex] passes the following points
[tex](x,y) = \{(0,5), (1, 5\frac 34), (2,6\frac 12)\}[/tex]

In an isosceles triangle, the length of the base is half of the length of a leg. The perimeter of this triangle is 50 cm. Find the lengths of all sides.
Answer:
10 cm, 20 cm, 20 cmStep-by-step explanation:
Let the base is x, then the legs are 2x each.
The perimeter is:
x + 2x*2 = 505x = 50x = 10The base is 10 cm and legs are 20 cm each.

Answer:
A) 23+x = 35
x = 12
Step-by-step explanation:
The question is asking you to find the equation and variable that best represents the scenario. We know that Emily had 35 dollars and had 7 dollars after paying for everything. This means that 7 plus what she spent must equal 35. However, we only know the cost of the ticket. So, add the cost of the ticket to the money left to figure out part of the equation. This equals 23 dollars. Therefore, whatever is left must be what she spent on lunch. So, the equation should look like 23 + x = 35. This is because the $23 is the ticket/the amount left and the x is the cost of lunch. Together they equal what Emily brought to the fair.

A. y=5.5x+6.75
B.y=13.5x-1.25
C.y=13.5x+12.25
D.y=6.75x+5.5
Answer:
D. y = 6.75x + 5.5Step-by-step explanation:
The slope intercept form:
y = mx + b, where m- slope, b- y-interceptUse two ordered pairs from the table and work out the equation.
(1, 12.25) and (3, 25.75)Find the slope:
m = (y₂ - y₁)/(x₂ - x₁)m = (25.75 - 12.25)/(3 - 1) = 13.5/2 = 6.75Find the y- intercept:
12.25 = 6.75*1 + bb = 12,25 - 6.75b = 5.5The equation is:
y = 6.75x + 5.5Correct choice is D
Slope
m=(25.75-12.25)/3-1m=6.75Equation in point slope form
y-12.25=6.75(x-1)y=6.75x+5.55{[(4+6-8)-4]-(1+2⁴-3+6)}

Hello there!
When we are given the graph of a line and two points on the graph, we can calculate the slope of the line using Rise/Run.
Rise=How many units we move up (here, the rise is 3)
Run=How many units we move left or right (Here, the run is 5)
So the slope of this line is [tex]\frac{3}{5}[/tex]
