x = number of weeks which is some positive whole number

50x = amount saved after x weeks, when saving $50 per week

50x+800 = add on the 800 she already has

The expression 50x+800 is the total money saved. We set this equal to the 1150 to set up the equation we're after

<h3>Answer:  50x+800 = 1150</h3>

A japanese beetle has a length between 0.3 and 0.5 inch.find two lengths that are within the given span.express them as a fracti
DanielleElmas [232]
Hello,

One method of finding a value in between two other numbers is taking the average, it will always be between the numbers. To find the average of two numbers, add the numbers and divide it by how many numbers there are. 

In this case, we have:
(0.3) + (0.5) /2 = 0.8 / 2 = 0.4

So, 0.4 is one length that is within the given span.
Another example is 0.45, which is also between 0.3 and 0.5.

0.4 represented as a fraction is 4/10. However, this can be simplified (notice 4 and 10 are both divisible by 2). To simplify this fraction, divide the numerator and denominator of the fraction by 2 to get (4/2) / (10/2) = 2/5.

0.45 represented as a fraction is 45/100. This fraction can also be simplified (notice 45 and 100 are both divisible by 5). To simplify this fraction, divide the numerator and denominator of the fraction by 5 to get (45/5) / (100/5) = 9/20.

Two lengths that are within the span are 2/5 inches and 9/20 inches, both of which are in simplest form.

Hope this helps!

What are the values of x in the equation 4x2 + 4x - 3 = 0?
9966 [12]

Answer:

x=  0.5

or x=  -1.5

Step-by-step explanation:

Let's solve your equation step-by-step.

4x2+4x−3=0

Step 1: Factor left side of equation.

(2x−1)(2x+3)=0

Step 2: Set factors equal to 0.

2x−1=0 or 2x+3=0

x= 1/2 or x= −3/2
