The amount that Susan charges per hour for babysitting is directly proportional to the number of children she is watching. She charges $4.50 for 3 kids.
How much would she charge to babysit 5 kids? **Weegy:** 4.50 dollars/(3 children) = 1.50 dollars/child
5 children ? 1.50 dollars/child = 7.50 dollars
She would charge $7.50 to babysit 5 kids. **User:** What is the equation of a direct variation that goes through the points (-6, 2) and (9, -3)?
**User:** Find 4 1/5 · 7 2/3 **User:** 4 1/5 · 7 2/3
**User:** 4 1/5 x 7 2/3
**Weegy:** x+(4)/(x)+2=x+(1)/(x)+5
To add fractions, the denominators must be equal. The denominators can be made equal by finding the least common denominator (LCD). In this case, the LCD is x. [ Next, multiply each fraction by a factor of 1 that will create the LCD in each of the fractions.
x+(4)/(x)+2=x*(x)/(x)+(1)/(x)+5*(x)/(x)
Multiply x by x to get x^(2).
x+(4)/(x)+2=(x^(2))/(x)+(1)/(x)+5*(x)/(x)
Multiply 5 by x to get 5x.
x+(4)/(x)+2=(x^(2))/(x)+(1)/(x)+(5x)/(x)
Combine the numerators of all expressions that have common denominators.
x+(4)/(x)+2=(x^(2)+1+5x)/(x)
Reorder the polynomial x^(2)+1+5x alphabetically from left to right, starting with the highest order term.
x+(4)/(x)+2=(x^(2)+5x+1)/(x)
Find the LCD (least common denominator) of x+(4)/(x)+2+((x^(2)+5x+1))/(x).
Least common denominator: x
Multiply each term in the equation by x in order to remove all the denominators from the equation.
x*x+(4)/(x)*x+2*x=(x^(2)+5x+1)/(x)*x
Cancel the common factor of x in the denominator of the first term (4)/(x) and the second term x.
x*x+(4)/( x )* x +2*x=(x^(2)+5x+1)/(x)*x
Reduce the expression by removing the common factor of x in the denominator of the first term (4)/(x) and the second term x.
x*x+4*1+2*x=(x^(2)+5x+1)/(x)*x
Multiply x by x to get x^(2).
x^(2)+4*1+2*x=(x^(2)+5x+1)/(x)*x
Multiply 4 by 1 to get 4.
x^(2)+4+2*x=(x^(2)+5x+1)/(x)*x
Multiply 2 by x to get 2x.
x^(2)+4+2x=(x^(2)+5x+1)/(x)*x
Reorder the polynomial x^(2)+4+2x alphabetically from left to right, starting with the highest order term.
x^(2)+2x+4=(x^(2)+5x+1)/(x)*x
Cancel the common factor of x from the denominator of the first expression and the numerator of the ... (More)

4 1/5 · 7 2/3

= 21/5 · 23/3

= 483/15

= 161/5

= 32 1/5

= 21/5 · 23/3

= 483/15

= 161/5

= 32 1/5

convex **Weegy:** The most commonly-seen type of lens is the convex lens. This type of lens is often used for close examination of small objects, such as rare stamps or coins. [ Children often use such a lens to concentrate sunlight to burn small pinholes in pieces of paper. That result by itself shows the power of concentrated light from the sun. But there must be more to it than that. Let's see if we can define the behavior of lenses a bit more specifically. ] **User:** how many sides does convex have? (More)
