10. The sum of two numbers is 102. One number is three less than twice the other.
What are the two numbers?
Answers
Answer:
(2n -3) + n = 102
2n - 3 + n = 102
3n - 3 = 102
3n = 105
n = 35 (the first number)
SO...
The other number is (2 x 35) - 3 =
70 - 3 = 67 (the second number)
The numbers are 35 and 67.
35 + 67 = 102 CHECK!

A vendor sells hot dogs and bags of potato chips. A customer buys 3 hot dogs and 5 bags of potato chips for $9.50. Another customer buys 2 hot dogs and 5 bags of potato chips for $8.00. Find the cost of each item.
Answers
Step-by-step explanation:
3d + 5p=9.50
2d + 5p=8
1 hot dog cost $1.50
2 × 1.50 + 5p = 8
3 + 5p = 8
5p = 8 - 3
5p = 5

how to I do Ratios with cross multiplying
Answers
Answer:
To cross multiply, multiply the numerator from one side with the denominator of the other side and put that product on one side of the equation. Do the same with the other numerator/denominator and put that on the other side. From there, solve for the unknown part.
So your ratio might look like this:
4/6=x/12
6x=12(4)
6x=48
x=8
So in this case 4/6 would equal 8/12.

In the diagram, the radius of the outer circle is 2x em and the radius of the inside circle is 6 cm. The area of the shaded region is 220 cm? What is the value of x2
Answers
Answer:
Answer: 8 (second choice)
Step-by-step explanation:
Area of a Circle
Given a circle of radius r, the area is calculated by the formula:
[tex]A=\pi\ r^2[/tex]
There are two circles in the diagram. The outer circle has a radius of r1=2x, thus its area is:
[tex]A_1=\pi\ (2x)^2[/tex]
The interior circle has a radius of r2=6 cm, thus its area is:
[tex]A_2=\pi\ 6^2=36\pi[/tex]
The shaded area is obtained by subtracting A1-A2:
[tex]A=\pi\ (2x)^2-36\pi[/tex]
The value of the shaded area is given as 220π cm2. Equating:
[tex]\pi\ (2x)^2-36\pi=220\pi[/tex]
Dividing by π:
[tex](2x)^2-36=220[/tex]
Adding 36:
[tex](2x)^2=220+36=256[/tex]
Taking square root:
[tex]2x=\sqrt{256}=16[/tex]
Dividing by 2:
x = 8 cm

Step-by-step explanation:
1. 3x - 9 = 30
add 9 to 30 ( 30 + 9 = 39) divide 39 by 3 (39 ÷ 3 = 13)
2. x/5 + 4 = 6
subtract 4 from 6 (6 - 4 = 2) multiply 2 by 5 (2 x 5 = 10)
3. x/2 + 6.5 = 8
subtract 6.5 from 8 (8 - 6.5 = 1.5) multiply 2 by 1.5 (2 x 1.5 = 3)
4. -2x + 2 = 18
subtract 2 from 18 (18 - 2 = 16) divide -2 from 16 (16 ÷ -2 = -8)
