Answer:

VX = 37

Step-by-step explanation:

Since VX is the midsegment, based on the midsegment theorem we would have:

VX = ½(UY)

VX = s - 37

UY = s

Plug in the values

s - 37 = ½(s)

Multiply both sides by 2

2(s - 37) = s

2s - 74 = s

Collect like terms

2s - s = 74

s = 74

VX = s - 37

Plug in the value of s

VX = 74 - 37 = 37

kap26 [50]

Answer:

Step-by-step explanation:

n + q = 20

.05n + .25q = 3.00

5n + 25q = 300

n + q = 20

5n + 25q = 300

-5n - 5q = -100

20q = 200

q = 10 quarters

n + 10 = 20

n = 10 nickels

(10 nickels, 10 quarters)

scoray [572]

Answer:

The price of collection of novels before taxes was $409.10.

Step-by-step explanation:

Given:

Ava bought a collection of hardcover novels and paid $450 including sales tax.

The sales tax is 10%.

Now, to find the price of collection of novels before taxes.

Let the price of collection of novels before sales tax be $x$ .

The price of collection of novels including sales tax = $450.

Rate of sales tax = 10%.

Now, to get the price before sales tax by putting an equation:

$x=450-10\%\ of\ x$

$x=450-\frac{10}{100} \times x$

$x=450-0.10\times x$

$x=450-0.10x$

Adding both sides by 0.10 $x$ we get:

$1.10x=450$

Dividing both sides by 1.10 we get:

$x=\$409.10.$

Therefore, the price of collection of novels before taxes was $409.10.

Simplify the expression: 2(3x – 5) + 4x - 7

Ksivusya [100]

Answer:

$\huge{ \fbox{ \sf{10x - 17}}}$

Step-by-step explanation:

$\sf{ \: 2(3x - 5) + 4x - 7}$

Distribute 2 through the parentheses

$\mapsto{ \sf{6x - 10 + 4x - 7}}$

Add the like terms : 6x and 4x

Like terms are those which have the same base.

$\mapsto{ \sf{10x - 10 - 7}}$

$\underline{ \text{Remember!}} :$ The negative integers are always but added but posses the negative ( - ) sign.

$\mapsto{ \sf{10x - 17}}$

Hope I helped!

Best regards! :D
