Paula wants to buy 3 shirts and 2 belts. The shirts cost $16.89 each, and the belts cost $8.97 each. Paula has $45. Which of the
Mariana [72]

Answer:

Paula needs additional $23.61

Step-by-step explanation:

Given

Shirts = 3

Belts = 2

Cost(shirt) = \$16.89

Cost(belt) = \$8.97

Amount = \$45

Required

Estimate how much money is needed more

First, we need to estimate the total amount of 3 shirts and 2 belts:

Total = Quantity * Cost

Total = 3 * \$16.89 + 2 * \$8.97

Total = \$50.67 + \$17.94

Total = \$68.61

Subtract the amount with Paula from the calculated total.

Difference = \$68.61-\$45

Difference = \$23.61

Hence:

Paula needs additional $23.61

Write an equation of the line that is parallel to -x + y = 5 and passes through the point (2,-5).
trasher [3.6K]

Remember that the slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

so convert the equation -x + y = 5 into slope intercept form by adding x to both sides

(-x + x) + y = 5 + x

0 + y = 5 + x

y = 5 + x

To match the slope intercept formula switch the x and 5 around

y = x + 5

If lines are parallel then they have the same slope (m) but they have different b

This means that the slope of the line will be 1 (in front of the x is an invisible 1 which would be m)

This is what we have so far...

y =  x + b

Now we must find b

To do that you must plug in the point the line goes through in the x and y of the equation.

(2, -5)

-5 = 1(2) + b

-5 = 2 + b

-7 = b

y = x + (-7)

y = x - 7

Hope this helped!

Find the measure of the indicated angle below
Norma-Jean [14]

Answer:

The measure of x is 70\°

Step-by-step explanation:

we know that

The formula to calculate the sum of the internal angles of a polygon is equal to

S=(n-2)*180\°

where

n is the number of sides

In this problem we have

n=9\ sides

substitute

S=(9-2)*180\°=1,260\°

Find the measure of each internal angle

Divide the sum of the internal angles by the number of sides

1,260\°/9=140\°

The value of x is half the measure of internal angle

so

x=140\°/2=70\°
