1.

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

Let p stand for the cost of the printer, so

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

$\Rightarrow 525+p=650$

$\Rightarrow p=650-525=125$

2.

Bonnie ordered 27 products from one company

Let m stand for the number of missing items

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

$\Rightarrow 19+m=27$

$\Rightarrow m=27-19=8$

3.

Terri bought four lipsticks for a total cost of $20

Let l stand for the cost of one lipstick.

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

$\Rightarrow 4 \times I=20$

$\Rightarrow I=5$

4.

Each survey takes him about 10 minutes to complete

Let h stand for the number of hours

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

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

5.

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

Let A stands for the average.

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

6.

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.

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

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

Hiro and his co-workers had lunch at a restaurant near their work. An 18% tip on their bill was $10.08. How much was the bill, n

Ghella [55]

Answer:

$8.27

Step-by-step explanation:

First we need to find the tip. We know it was 18% of the total. So...

x (the variable we need to find) 18%

__ = ___

10.08 (the total bill including tip) 100%

cross multiply

100x = 181.44

-------------------- (divide by 100 to get x by itself)

100

x = 1.81 (The 18% tip that was given)

So now we know how much the tip was, we subtract it from the bill

10.08 - 1.81 = $8.27

Which of the following is NOT equivalent to -3(10 - 4)?

Alex787 [66]

Answer:

-3(10) - 4

Step-by-step explanation:

-3(10 - 4) = -18

-3(10) - 4 = -34

-30 - (-12) = -18

-3(10) - (-3)(4) = -18

-18 = -18

7th Grade Mock EOG - Math Ne

D. 17 inches
To be a triangle, any two sides have to add to be larger than the remaining side. An isosceles triangle has two sides that are the exact same length, which eliminates options B and C. 8 + 8 = 16, which is less than 17, so option A is out, leaving only option D.

Use the commutative property to write an equivalent expression to 4g + 13, and show that they are equivalent for g = 10 and g =

Ivan

4g+13 is the same as 13+4g when using the commutative property.

Specifically, it is the commutative property of addition.

This says we can add two numbers in any order. For example, 7+9 = 16 and 9+7 = 16 as well. So 7+9 = 9+7. More generally, x+y = y+x for any pair of real numbers for x and y.

---------------------

If we plug in g = 10, then

4g+13 = 4*10+13 = 40+13 = 53

and

13+4g = 13+4*10 = 13 + 40 = 53

We get 53 both times, so 4g+13 = 13+4g is confirmed to be true when g = 10

---------------------

Repeat for g = 2

4g+13 = 4*2+13 = 8+13 = 21

and

13+4g = 13+4*2 = 13+8 = 21

both results are the same, so 4g+13 = 13+4g works for g = 2 as well.

You should find it works for any number you pick for g.
