<u>answer:</u> $m = 1.2$

$17.70 = \frac{7}{2} m + 13.50$ | subtract 13.50 and move it over

$4.2 = \frac{7}{2}m$ | divide by 7/2

$1.2 = m$ | final answer

Two pieces of equipment were purchased for a total of $4000. If one piece cost $850 more than

ruslelena [56]

The price of less expensive equipment is $1575.

Step-by-step explanation:

Let,

Price of one equipment = x

Price of other equipment = y

According to given statement;

x+y=4000 Eqn 1

x = y+850 Eqn 2

Putting Eqn 2 in Eqn 1

$(y+850)+y=4000\\y+850+y=4000\\2y=4000-850\\2y=3150$

Dividing both sides by 2;

$\frac{2y}{2}=\frac{3150}{2}\\y=1575$

Putting y=1575 in Eqn 2;

$x=1575+850\\x=2425$

The price of less expensive equipment is $1575.

Kim walked diagonally across a rectangluar field that measured 100 ft by 240ft how far did she walk?

elena-s [515]

Draw a triangle and you can see that you can use the Pythagorean Theorem.
C = root (100^2 + 240^2)
C = 260ft

Solve the system

Alexxandr [17]

Answer:

x = $\frac{2u+v}{7}$

y = $\frac{2v - 3u }{7}$

Jacobian value = 1/7

Step-by-step explanation:

Given data:

u = 2x -y

v = 3x + 2y

solving the system for x and y in terms of u and v

x = $\frac{2u+v}{7}$

y = $\frac{2v - 3u }{7}$

The value of the Jacobian = 1/7 ( solution attached below )

E bisects line segment df. df=2y, and ef=8y-3. find de, ef, and df.

Usimov [2.4K]

1/2DF = EF

1/2(2y) = 8y - 3

Multiply 1/2 * 2y.

y = 8y - 3

Subtract 8y from both sides.

-7y = -3

Divide both sides by -7.

y = 3/7

Plug 3/7 for y into DF and EF.

DF: 2(3/7) = 6/7

EF: 8(3/7) - 3 = 24/7 - 3 = 3/7

EF = DE because they are bisected, so DE = 3/7
