<u>Solution-</u>

Bill bought a computer and a printer for a total of $650.

Let p stand for the cost of the printer, so

$\text{Cost of the computer + p} =650$

$\Rightarrow 525+p=650$

$\Rightarrow p=650-525=125$

Bonnie ordered 27 products from one company

Let m stand for the number of missing items

$\text{Number of item she got + m} =27$

$\Rightarrow 19+m=27$

$\Rightarrow m=27-19=8$

Terri bought four lipsticks for a total cost of $20

Let l stand for the cost of one lipstick.

$Price\ of\ one\ lipstick \times I=20$

$\Rightarrow 4 \times I=20$

$\Rightarrow I=5$

Each survey takes him about 10 minutes to complete

Let h stand for the number of hours

$Tota\l time\ taken\ = Time\ taken\ for\ 1\ survey\ in\ hours\times no.\ of\ survey$

$Total\ time\ taken\ =\frac{10}{60} \times 30 = 5 hours$

Andy played golf three times during his vacation. His scores were 92, 87, and 88.

Let A stands for the average.

$Average \ score=A= \frac{Score_1+Score_2+Score_3}{3} =\frac{92+87+88}{3}=89$

Tickets to a local basketball team’s games cost $12 each. Brendon and Ed each bought tickets to four games.

Total tickets = 2×4=8 (∵ They each bought 4 tickets)

(Let t stand for the amount spent on tickets.

$Amount\ spent\ on\ tickets\ =price\ of\ 1\ ticket \times total\ ticket}$

$\Rightarrow t=12 \times 8=96$

Solve for x 5x + 3 - 2x = 24 (also don't have the answer be a fraction)

Yuki888 [10]

Answer:

x=7

Step-by-step explanation:

Let's solve your equation step-by-step.

5x+3−2x=24

Step 1: Simplify both sides of the equation.

5x+3−2x=24

5x+3+−2x=24

(5x+−2x)+(3)=24(Combine Like Terms)

3x+3=24

Step 2: Subtract 3 from both sides.

3x+3−3=24−3

3x=21

Step 3: Divide both sides by 3.

From a train station, one train heads north, and another heads east. Some time later, the northbound train has traveled 12 miles

tigry1 [53]

9514 1404 393

Answer:

20 miles

Step-by-step explanation:

The north and east distances form the legs of a right triangle. The straight-line distance between the trains is the hypotenuse of that triangle. The Pythagorean theorem can be used to find the length of the hypotenuse (d).

d² = 12² +16²

d² = 144 +256 = 400

d = √400 = 20

The two trains are 20 miles apart.

<em>Additional comment</em>

You may recognize the given distances are in the ratio 3 : 4. You may recall that side ratios of 3 : 4 : 5 make a right triangle. If so, you recognize that the straight-line distance is (4 miles)×5 = 20 miles. (3:4:5 right triangles show up often in algebra and geometry problems, so might be something you want to look for.)

Find the midpoint of a line segment that has the endpoints (3,5) and (5,-3) *

igor_vitrenko [27]

Answer:

<h3>The answer is (4 , 1)</h3>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

$M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )\\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(3,5) and (5,-3)

We have

$M = ( \frac{3 + 5}{2} , \frac{5 - 3}{2} ) \\ = ( \frac{8}{2} , \frac{2}{2} )$

We have the final answer as

Hope this helps you
