Given:

Total tips = $ 77.40

Ratio of tips sharing = 2 : 3 : 4

To find:

How much more does Brian get over Paul

Solution:

Let 2x, 3x and 4x be the cost of tips got by Paul, Colin and Brian.

Total cost of tips =$ 77.40

2x + 3x + 4x = 77.40

9x = 77.40

Divide by 9 on both sides.

$$\frac{9x}{9}=\frac{77.40}{9}$

x = 8.6

Brian gets = 4(8.6) = $34.4

Paul gets = 2(8.6) = $17.2

Difference = 34.4 - 17.2

= 17.2

Therefore Brian gets $17.2 more than Paul.

Please help! Find the value of C such that each expression is a perfect-square trinomial.

crimeas [40]

For ax^2+bx+c
when a=1
take 1/2 of b and square it
that is what c should be ideally

p^2-30p=c
-30/2=-15
(-15)^2=225
c=225
(p-15)^2 is factored form

k^2-5k+c
-5/2
(-5/2)^2=25/4
c=25/4
factored form is (x-5/2)^2

Jones Street is parallel to Lincoln Street, and both streets are intersected by Elm Street and Avenue A. Jones Street J 105° m E

kvv77 [185]

We have:

Alternate angles are equal in measure, therefore:

$\angle E=105^{\circ}$

Then, The angles E, JEA and 32° add up to 180° because they form a straight angle. So:

$\begin{gathered} 105+\angle JEA+32=180 \\ 137+\angle JEA=180 \\ 137+\angle JEA-137=180-137 \\ \angle JEA=43 \end{gathered}$

Answer: 43°

If f(x) = x/2=-3 and g(x)=3x^2+x-6,find (f+g)(x)

Wewaii [24]

(f+g)(x) is 3x^2 + 3x/2 - 9

(f+g)(x)=f(x)+g(x)=x/2-3+3x^2+x-6= 3x^2 + 3x/2- 9

Is the decimal for 4 over 3 a repeating decimal ? expain

Alenkasestr [34]

Yes, the decimal form of $\frac{4}{3}$ is indeed a repeating decimal. The expression is equivalent to $1 \frac{1}{3}$ , which is also 1.3333333 or "1.3 bar", signifying that the 3 will repeat infinitely.
