How to set the answer up

Korolek [52]

Let s and g represents the numbers of suits and gowns produced.

The number of zippers used is 2s+g.

The number of buttons used is 5s+8g.

In order to use all of the available zippers and buttons, we must have ...

2s + g = 171
5s + 8g = 576

Cramer's rule tells you the solution to the system

ax +by = c
dx +ey = f

Is given by

x = (bf-ey)/(bd-ea)
y = (cd-fa)/(bd-ea)

Using this rule on the equations for zippers and buttons, we have

... s = (1·576 -8·171)/(1·5 -8·2) = -792/-11 = 72

... g = (171·5 -2·576)/-11 = -297/-11 = 27

72 suits and 27 gowns can be made from available zippers and buttons.

The diameter of the circle is 10 units what is the radius of the circle

gayaneshka [121]

Answer:

Radius is 5 units

Step-by-step explanation:

The radius of a circle will always be 1/2 of the diameter.

This gives the formula:

$r=\frac{d}{2}$

(substitute known values)

$r=\frac{10}{2}$

(divide 10 by 2)

$r=5$

Therefore the radius is five

Solve for x 14 x square+7x-6

irina [24]

Answer:

x=0.450765 or x=−0.950765

Step-by-step explanation:

14x² + 7x - 6

→ Find the product, sum and factors

Product = -6

Sum = 7

Factors = No factors

→ Since there are no factors utilise the quadratic formula

$\frac{-b+-\sqrt{b^{2}-4ac } }{2a}$

→ List the values of a, b and c

a = 14

b = 7

c= -6

→ Substitute into the formula

$\frac{-7+-\sqrt{7^{2}-4*14*-6} }{2*14}$

→ Simplify

x=0.450765 or x=−0.950765
