Answer: x=y/(3b-7)
Step-by-step explanation:
To solve for v, you want to use algebraic properties to isolate x.
y=3bx-7x [factor out x]
y=x(3b-7) [divide both sides by 3b-7]
x=y/(3b-7)
Now, we know that x=y/(3b-7).
Answer:
3bx -7x = y
or, x(3b -7) = y
or, x= y/(3b -7)

-6(3 + x) + 2(3x + 5) = 0
Answer:
No solution
Step-by-step explanation:
Step 1: Write equation
-6(3 + x) + 2(3x + 5) = 0
Step 2: Solve for x
Distribute: -18 - 6x + 6x + 10 = 0
Combine like terms: -8 ≠ 0
∴ No solution
No answer
Step-by-step explanation:
-6(3+x) Multiply -6 by 3=-18. -18+-6x 2(3x+5) 6x+10
(-18+-6x) + (10+6x) = (-8 = 0).
The selling price for a classic speedboat is $12,000. what was the speedboats original price if it is currently selling for $2,000 less than two times its original price?
Answer:
$7,000
Step-by-step explanation:
Let [tex]x[/tex] equal the original price.
[tex]12,000+2000=2x[/tex]
Combine like terms.
[tex]14,000=2x[/tex]
Divide by the coefficient of [tex]x[/tex], which in this case is [tex]2.[/tex]
[tex]7,000=x[/tex]
If you like the variable on the left, rewrite:
[tex]x=7,000[/tex]
A shopper paid 11/100 of a dollar for 1/16 of a kilogram of nails. What was the rate in dollars per
kilograms?
Answer:
[tex]Rate = \$1.76/kg[/tex]
Step-by-step explanation:
Given
[tex]\frac{1}{16}kg[/tex] of nails costs [tex]\$ \frac{11}{100}[/tex]
Required
Determine the rate
The rate, in this case, will be calculated as:
[tex]Rate = \frac{amount}{weight}[/tex]
[tex]Rate = \frac{\frac{11}{100}}{\frac{1}{16}}[/tex]
This gives
[tex]Rate = \frac{11}{100}/\frac{1}{16}[/tex]
[tex]Rate = \frac{11}{100} * 16[/tex]
[tex]Rate = \frac{176}{100}[/tex]
[tex]Rate = \$1.76/kg[/tex]
Answer:

Step-by-step explanation:
Write the ratio in simplest form for area of pool/ area of yard
Answer:
Option (C)
Step-by-step explanation:
From the map attached,
Area of the rectangular yard = length × width
Length of the yard = 10 units
Width of the yard = 8 units
Area = 10 × 8
= 80 square yards
Since, pool is a composite figure of two rectangles,
Therefore, area of the pool = Area of large segment + Area of the small pool
= (5 × 6) + (3 × 3)
= 30 + 9
= 39 square units
Ratio of Area of the pool and area of yard = [tex]\frac{39}{80}[/tex]
Therefore, Option (C) will be the answer.

Step-by-step explanation:
Which of the numbers 8,9, or 10 is the solution to 70=8-x
Answer:
Step-by-step explanation:
Add x to both sides.
70 +x = 8
Subtract 70 from both sides.
x = 8 - 70
x = - 62

A merchant mixed 10 lb of a cinnamon tea with 2 lb of spice tea. The 12-pound mixture cost $13. A second mixture included 16 lb of the cinnamon tea and 8 lb of the spice tea. The 24-pound mixture cost $28. Find the cost per pound of the cinnamon tea and of the spice tea.
Step-by-step explanation:
Let's say c is the price of cinnamon tea, and s is the price of spice tea.
10c + 2s = 13
16c + 8s = 28
Divide the second equation by 4:
4c + 2s = 7
Subtract from the first equation:
6c = 6
c = 1
Use any equation to find s.
s = 1.5
Therefore, the cinnamon tea costs $1 per pound and the spice tea costs $1.50 per pound.

solve for x 4x+15=71
Answer:
x=14
Step-by-step explanation:
4x +15 =71
4x =71 - 15
4x =56
x=56 :4
x=14
4 ×14 +15 =71
56 +15 =71
71 =71
Answer: X=14
Step-by-step explanation: Plug 14 in for x. 4*14 equals 56. 56+15 equals 71. and 71=71.
The circumference of a circle is 16Pi ft what is the radius
Answer:
Given circumference (C) = 16
Radius =

2.5464790894703
Diameter =
C =
π
5.0929581789407
Area =
C2 =
4π
20.371832715763
Step-by-step explanation:
We've all seen circles before. They have this perfectly round shape.
Every circle has a center, which is a point that lies exactly at the... well... center of the circle. A circle is a shape where the distance from the center to the edge of the circle is always the same. In order to calculate the radius, you need the circumferance or the diameter.
Answer:
Pi is a number that is approximated by 3.14, or 22/7. It is the ratio of the circumference to the diameter of any circle. This ratio can be rearranged to find circumference of a circle by multiplying pi times diameter
Step-by-step explanation:
The perimeter of a rectangular flower bed is 68 feet. Find the dimensions of the flower bed if the length is 2 less than three times the width.
Answer:
Step-by-step explanation:
Perimeter of the rectangular flour = 2(Length+Width)
P = 2(L+W)... 1
If if the length is 2 less than three times the width, then L = 3W - 2.... 2
Substitute equation 2 into 1;
P =2(3W-2+W)
68 = 2(4W-2)
68 = 8W-4
8W = 68+4
8W = 72
W = 72/8
W = 9 feet
Since L = 3W-2
L = 3(9)-2
L = 27-2
L = 25
The length is 25ft and the width is 9ft

B = 6/13 Y +12 Solve for y
Answer:
y = (13/6)(b - 12)
Step-by-step explanation:
b = 6/13 y + 12
Subtract 12 from both sides.
b - 12 = 6/13 y
Multiply both sides by 13/6.
(13/6)(b - 12) = y
y = (13/6)(b - 12)

=75/7Which of the following equations are dimensionally consistent?
(a) x=1/2at2,
(b) t=v/x,
(c) t=(2x/a)1/2
Answer:
A. x = 1/2at²
Step-by-step explanation:
Among the equations, the equation that is dimensionally consistent is x=1/2at² where;
x is the distance in meters (dimension is length (L))
a is the acceleration in m/s² (dimension is L/T²)
t is the time in seconds (s) (dimension of time is T)
Substituting the dimensions into the formula to check if we are going to arrive at the dimension for distance;
1/2at² = 1/2(L/T²)T²
= 1/2× L/T² × T²
= 1/2 × L
Since L which is the resulting dimension is the dimension for distance (x), this means that the equation x = 1/2at² is dimensionally consistent.
