4/5-1/2 answer my question

4/5 - 1/2 =

3/10 in exact form

0.3 in decimal form

When subtracting a fraction, you always have to make sure your denominator/divisor's are the same.

Therefore you would find the Least Common Multiple of 5 and 2

Both would eventually come to 10, multiplying 4/5 by 2 on both the numerator and the denominator

Do the same with 1/2 except you multiply this one by 5 on both the numerator and the denominator.

Your fractions would then be 8/10 and 5/10

Then you subtract

8/10 - 5/10 = 3/10

(The Denominator does not change after all this)

Hope this helps :)

3/10 you cross multiply 5x2=10 so the denominator will be 10 and then cross multiply the numberators by the different denominator make sense? so 5x 1=5 and that mean 1/2=5/10 and 4/5=8/10 and the final answer when u subtract is 3/10 makes sense? u know what i mean jelly bean?

Which statement is true regarding the functions on the

prisoha [69]

Answer:

f(2) = g(2)

General Formulas and Concepts:

Alg I

Reading a Cartesian Plane
Identifying Coordinates
Solutions of systems of equations

Step-by-step explanation:

We see from the graph that f(x) and g(x) intersect at x = 2. Therefore, the point at x = 2 would be equivalent in both graphs/be a solution to both equations.

Therefore, f(2) must equal g(2), as they intersect each other at that point and have the same value of 0.

(09.06 HC) The function H(t) = −16t2 + 112t + 24 shows the height H(t), in feet, of a cannon ball after t seconds. A second cann

erma4kov [3.2K]

PART A:

The table of h(t) and g(t) for the value of x between 4 and 7 inclusive are shown below.

The solution for h(x)=g(x) lies between x = 4 and x = 5, this is becuase the range of value given by h(4) and h(5) and g(4) and g(5).

The graph is shown in picture 2 to confirm this. The two functions intersect each other between x = 4 and x = 5

PART B:

The point of intersection is the point where the cannon balls will collide.

Amanda needs to make a garden plot which has an area less than 18 sq. feet. The length should be 3 feet longer than the width. W

SCORPION-xisa [38]

Answer:

Any width less than 3 feet

Step-by-step explanation:

Inequalities

The garden plot will have an area of less than 18 square feet. If L is the length of the garden plot and W is the width, the area is calculated by:

A = L.W

The first condition can be written as follows:

LW < 18

The length should be 3 feet longer than the width, thus:

L = W + 3

Substituting in the inequality:

(W + 3)W < 18

Operating and rearranging:

$W^2 + 3W - 18 < 0$

Factoring:

(W-3)(W+6)<0

Since W must be positive, the only restriction comes from:

W - 3 < 0

Or, equivalently:

W < 3

Since:

L = W + 3

W = L - 3

This means:

L - 3 < 3

L < 6

The width should be less than 3 feet and therefore the length will be less than 6 feet.

If the measures are whole numbers, the possible dimensions of the garden plot are:

W = 1 ft, L = 4 ft

W = 2 ft, L = 5 ft

Another solution would be (for non-integer numbers):

W = 2.5 ft, L = 5.5 ft

There are infinitely many possible combinations for W and L as real numbers.
