Answer:

−9.333

Step-by-step explanation:

(1): "6.75" was replaced by "(675/100)"

(675/100)+3/8*x-((13)*1/4)=0

Simplify 1/4

675 3 1

(———+(—•x))-(13•—) = 0

100 8 4

Simplify —

Equation at the end of step

675 3 13

(——— + (— • x)) - —— = 0

100 8 4

STEP

Simplify ——

Equation at the end of step

27 3x 13

(—— + ——) - —— = 0

Answer:

Rita = 300

John = 900

Rodell = 925

Step-by-step explanation:

rita = x (let

john = 3x ( john swims three times more than rita

rodell = 25 + 3x ( rodell swims 25 more than john

x + 3x + 25 + 3x = 2125

or, 7x + 25 = 2125

or, 7x = 2125 - 25

or, x = 2100/7

x = 300

hence,

x = 300

3x = 3 × 300

= 900

25 + 3x = 25 + 900

= 925

For what values of h and k does the linear system have infinitely many solutions?

Sophie [7]

Answer:

h=-32 and k=-24

Step-by-step explanation:

$4x_1 + 3x_2 = -1:a_1x_1 + b_1x_2=c_1\\hx_1 +kx_2=8:a_2x_1+b_2x_2=c_2$

For infinitely many solutions, lines must be same; $\frac{a_1}{a_2}=\frac{b_1}{b_2}=\frac{c_1}{c_2}\\\\=\frac{4}{h}=\frac{3}{k}=\frac{-1}{8}\\\\h=-32, k=-24$

What number should be added to the expression x2+2x to change it into a perfect square trinomial?

coldgirl [10]

Answer:

Option A. $1$

Step-by-step explanation:

we know that

A perfect square trinomial is equal to

$(x+a)^{2}=x^{2}+2xa+a^{2}$

In this problem we have

$x^{2}+2x$

equate the equations and solve for a

$x^{2}+2x=x^{2}+2xa+a^{2}$

$2x=2xa$

$a=1$

therefore

the perfect square trinomial is equal to $(x+1)^{2}$
