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

Geometry please help ASAP
Answer:
D) 22
Step-by-step explanation:
B is the midpoint. The midpoint is the point in a line that breaks the line into two equal segments. With that info, we know that BC = AC.
So that means:
3x - 14 = x + 10
Now solve this equation.
3x - 14 = x + 10
+14. +14
3x = x + 24
-x
2x = 24
/2. /2
X = 12.
Now we know the value of x, insert the value into x + 10.
12 + 10 = 22
The answer is 22
Answer:
B) 12
Step-by-step explanation:
Because,
3x - 14 = x + 10
3x - x = 10 + 14
2x = 24
x = 12

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

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+5.5I don't understand this question can someone help me with this please, please explain!! and thank you for the help!! If u dont know try your best :D
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 3m wide road runs around a circular park whose circumference is 132m . Find the cost of fencing the outer boundary of the road at the rate of $10 per m
Answer:
$ 1508.57 and please give brainliest
Step-by-step explanation:
The road around the park = 3 m wide,
and the circumference of the park = 132 m,
We have to find the cost of fencing
the outer boundary,
the rate = $10 per m
Step-by-step explanation:
As we know that the circumference
of a circle = 2 × 22÷7 × radius
2 × 22÷7 × radius = 132 m,
44 × radius = 132 m × 7,
44 × radius = 924 m,
radius = 924 ÷ 44 m
So, radius = 21 m ( smaller circle )
radius = 21 m + 3 m ( larger circle )
= 24 m
Usually, we fence on the borders means it's
the circumference of the larger circle
= 2 × 22÷7 × radius
= 44÷7 × 24 m
= 1056÷7 m
= 150.85 m
cost of fencing = $ 10/m
total cost = 150.85 × $ 10
= $ 1508.57

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]
