2(3x-2)+2(2x+7)=30 x=?​

Answer:

42 square units

Step-by-step explanation:

imagine the rectangle around the original shape, it would be LxW which wold be 9 x 6 = 54. Then if you find the area of the two triangles cut out of the left and right sides, each triangle area is 1/2 base x height, which is 1/2(6x2)=1/2(12)=6 and x2 for 2 triangles and that = 12.

Now subtract 54-12=42 sq. units shaded.

Answer:

Step-by-step explanation:

1.) 700*0.42 = 294. Out of the 700 people at the concert, 294 are tennagers.

2.) 1.07*$450 = $481.50, including sales tax (final price)

3.) 120/(100%-85%) = 120/0.15 = 800. Original amount of water is 800 ml (Check by 800mL*0.15, which equals 120 mL)

4.) 100-35-45 = 20%

250*20% = 50; Out of the 250 sandwiches, Josh made 50 ham sandwiches.

Answer:

Step-by-step explanation:

Answer:

6^5 * a^3 * b ^2

Step-by-step explanation:

6 occurs 5 times in this equation

so it would be 6^5 (6 to the 5th)

a occurs 3 times in this equation

so it would be a^3 (a to the 3rd)

b occurs 2 times in this equation

so it would be b^2 (b to the 2nd)

Answer:

6*4

b*2

a*3

Step-by-step explanation:

Answer:

$2500

Step-by-step explanation:

Given data

Percent commission from sale= 2%

We are told that an associate earned $50 from sales

Let the amount of the sales be x

so

2/100*x= 50

0.02x=50

Divide both sides by 0.02

x=50/0.02

x=2500

Hence the sales made was $2500

Answer:

The answer is c, 250.

Step-by-step explanation:

Smaller number = n - 100

Bigger number = n

n + n - 100 = 400

2n = 500

n = 250

Check that this is true:

250 + 250 - 100 = 400

Answer:

20 π unit ^3 is your answer mate. . .

Answer:

V = 62.8

Step-by-step explanation:

To get the answer. The equation is pi(r)^2. You square the radius (2 x 2) which equals 4 and then you times it by the height, which is 5. This gives you 20, and then you multiply pi to it (3.14) to get an exact answer of 62.8.

Answer:

2m - 20

Step-by-step explanation:

Given that:

First week minutes = m

Second week minutes = (2 * first week minutes - 20)

Second week = 2m - 20

Therefore, the expression for the number of practice minutes for the second week is :

2m - 20

Answer: 34%

Step-by-step explanation:

Given

Price is marked down by 60% with an additional discount of 15% on the marked down price

Suppose x is the original price of the item

After marking down, it is

[tex]\Rightarrow x-x\times 0.6=0.4x[/tex]

after additional discount it is

[tex]\Rightarrow 0.4x(1-0.15)=0.4x\times 0.85=0.34x[/tex]

Effective discount on the item is

[tex]\Rightarrow \dfrac{x-0.34x}{x}\times 100=66\%[/tex]

Thus, a person is paying [tex]100-66=34\%[/tex] of the original price

Answer:

Remain garden Area = 311 ft²

Step-by-step explanation:

Given:

Dimension of vegetable garden = 15 ft by 25 ft

Dimension of garden = 8 ft by 8 ft

Find:

Remain garden Area

Computation:

Remain garden Area = Area of vegetable garden - Area of Garden

Remain garden Area = [(15)(25)] - [(8)(8)]

Remain garden Area =  375 - 64

Remain garden Area = 311 ft²

Answer:

The Triangle

Step-by-step explanation:

Answer:

b and c

Step-by-step explanation:

Answer:

the third number is 11

Step-by-step explanation:

the first number is 5 so the second number since its five times the first is 25 and the third being 14 less then the second is 11

so 5+25+11= 41

Answer:

464 feet

Step-by-step explanation:

The Sine of the angle of inclination gives the increase in altitude.

This is because the Sine of an angle is equal to the Opposite side divided by the Hypotenuse side. i.e

Sin Ф = Opposite  ÷ Hypotenuse

Sin 5° = O ÷ 5328

0·08716 = O ÷ 5328

Make O the subject and multiply every fraction by 5328

(0·08716/1 × 5328)= (O/5328 × 5328)

464·388 = O

∴ The increase in altitude is 464·388 feet

This is supposed to be to the nearest foot so we round off

464·388 becomes 464 feet

Answer:

Step-by-step explanation:

A straight line has 180 degrees.

43 + b + 50 = 180       Collect like terms

b + 93 = 180                Subtract 93

b = 180 - 93

b = 87

a + b + 75 = 180      All triangles have 180 degrees.

a + 87 + 75 = 180    Combine like terms

a + 162 = 180           Subtract 162 from both sides

a = 180 - 162

a = 18

Step-by-step explanation:

as an = a(n-1)+4

then a4. = 7(4-1)+4

= 7(3)+4

= 21 +4

= 25

Answer:

C(68) = 20 degrees Celsius

Step-by-step explanation:

In the given formula C = 5/9 (F - 32), substitutte 68 for "degrees Fahrenheit:"

C(68) = (5/9)(68 - 32), or

          +(5/9)(36), or

C(68) = 20 degrees Celsius

Answer:

-18v + 9w +15

Step-by-step explanation:

-3(6v-3w-5)

You can use a table or multiply each term

-3(6v)  + -3(-3w) + -3(-5)

= -18v + (9w) + (15)

= -18v + 9w + 15

Answer:

You can buy 4 Pizzas

Step-by-step explanation:

if you think carefully the devilery fee is still $7

because even how many pizzas you odered,the devilery man can deliver them all together

divide the spare change with the price of each pizza.

55÷12=4 r.7

4×12= 48

$48 dollars for 4 pizzas and $7 for the delivery.

48+7=55

thus he bought 4 pizzas
