Simplify the expression 8+10p-4-7p

Answer:

x = 2

Step-by-step explanation:

Given

[tex]\frac{5}{2}[/tex] x - 3 = 2 ( add 3 to both sides )

[tex]\frac{5}{2}[/tex] x = 5 ( multiply both sides by 2 to clear the fraction )

5x = 10 ( divide both sides by 5 )

x = 2

Answer:

Mary has 12 friends, and a total of 13 people including her. Or, she has 25 friends, and a total of 26 people including her.

Step-by-step explanation:

First, we know that 26 is divisible by 1, 2, 13, and 26 because (2x13) and (1x26) both equal 26 but we know that Mary has more than 1 friend and if Mary is also added to the group where the candy is divided, that means that 1 and 2 are both out because Mary has more than 1 friend so 1 cannot be the answer and if Mary has 2 friends, that means that the candy would have to be divided 3 ways which is not possible evenly so the answer is either 12 friends or 25 friends.

Answer:

1/2x³y^6

Step-by-step explanation:

Answer:

let cp be x

mp= x+ (20% 0f x)= 1.2x

sp = mp -d%of mp= 1.2- 15% *1.2 =1.02x

profit = 40

sp-cp =40

1.02x-x=40

x=2000

cp =2000

mp= 1.2*2000=2400

Step-by-step explanation:

Answer:

  20

Step-by-step explanation:

Your equation is correct. To solve it subtract 1.5r from both sides and divide by the resulting coefficient of r.

  15 = 0.75r

  15/0.75 = r = 20

Answer:

6

Step-by-step explanation

265+48=313

553-313=240

240/60=6

Answer:

equation : 265 + 48T = 553

T = 6 hours

Step-by-step explanation:

equation

553 - 265 = 288

288 /48 = 6

the number of hours spent is 6

equation : 265 + 48T = 553

T = 6 hours

Answer:

8

Step-by-step explanation:

Answer:8 or -16

Step-by-step explanation:

a) If you mean 10x - 3(x²) when x=2

10(2)- 3(2²)= 20-12=8

b) If you meant 10x - 3x²=

10(2)-(3 x 2)²= 20-6²

20-36=-16

Step-by-step explanation:

Answer:

X=7 ST=11 RT=17

Step-by-step explanation:

RT=RS+ST. RS= 2(7)-8. ST=11

X+10=2x-8+11. =14-8=6. RT= x+10

X+10=2x+3. RS=6. 7+10=17

10=x+3. RT=17

X=7

Option 2

Step-by-step explanation:

[tex](5,4) = (x_1,y_1) \\ m = \frac{4}{5} [/tex]

Substitute values into the point slope form

y-y1 =m(x-x1)

y- 4= 4/5(x-5)

y -4= 4/5x -4

y= 4/5 x -4+4

y= 4/5x

At starting hot-air balloon starts 6 feet.

So, at t = 0 , h = 6 feet.

Now, distance travelled per minute is 20 feet.

So, extra distance travelled in t minutes is 20t feet.

Now,

Total height = Staring height + increase in height w.r.t time.

h = 6 + 20t

Therefore, the height h in feet as a function of time t in minutes is h = 6 + 20t .

Hence, this is the required solution.

Answer:

what was the temperature at first?

We just take the square root of 16384.

√16384 = 128

128^2 = 16384

Best of Luck!

According to the question,

Slant height, l = [tex]\displaystyle{\sf{ \sqrt{{r}^2 + {h}^2} = \sqrt{{3.5}^2 + {8.5}^2}}}[/tex]

[tex]\implies[/tex] [tex]\displaystyle{\sf{ = 9.192m}}[/tex]

curved surface area = [tex]\displaystyle{\sf{ \pi rl}}[/tex]

[tex]\implies[/tex] [tex]\displaystyle{\sf{ \frac{22}{7} \times 3.5 \times 9.192{m}^2}}[/tex]

[tex]\implies[/tex] [tex]\displaystyle{\sf{ 101.112}}[/tex]

i.e., Area of the cloth is 101.11m²

Now, length of the cloth required = [tex]\displaystyle{\sf{ \frac{area}{width}}}[/tex]

Answer:

p=2

Step-by-step explanation:

-7p = -3p - 8

Add 3p to each side

-7p+3p = -3p+3p - 8

-4p = -8

Divide each side by -4

-4p/-4 = -8/-4

p = 2

Answer:

Answer:

pit it on -4 because your reflecting it on x

Answer:

4:00

Step-by-step explanation:

Step-by-step explanation:

4ˣ + 2¹⁺²ˣ = 50

Rewrite 4 as a power of 2.

2²ˣ + 2¹⁺²ˣ = 50

Factor out 2²ˣ.

2²ˣ (1 + 2) = 50

2²ˣ = 50/3

Take log of both sides.

ln(2²ˣ) = ln(50/3)

Use exponent property.

2x ln 2 = ln(50/3)

Solve for x.

x = ln(50/3) / (2 ln 2)

Simplify.

x = ln(50/3) / (ln 4)

x ≈ 2.03

[tex] r^2 [/tex]

All choices are incorrect.

Step-by-step explanation:

Remember that [tex] r = r^1 [/tex].

Also remember the rule: [tex] \dfrac{a^m}{a^n} = a^{m - n} [/tex]

[tex] \dfrac{r^3}{r} = [/tex]

[tex] = \dfrac{r^3}{r^1} [/tex]

[tex] = r^{3 - 1} [/tex]

[tex] = r^2 [/tex]

Answer: [tex] r^2 [/tex]

All choices are incorrect.

Answer: 12

Step-by-step explanation:

The answer is 12 because:

sizes are 3

toppings are 4

Using the Fundamental Counting Principal you multiple the selections

( 3 x 4=12)

So just learn the fundamental counting principal and it'll be easier. :)

The number of unique ways that you can order a bag of popcorn if you can only select one topping is 12 ways.

Combinations in probability refer to sequences of outcomes where the order does not matter.

Combinations are a way to calculate the total outcomes of an event where the order of the outcomes does not matter. To calculate combinations, we will use the formula nCr = n! / r! × (n - r)! where n represents the total number of items, and r represents the number of items being chosen at a time.

We are given the 3 different sizes of popcorn as;

Small

Medium

Large

Now, we are told that an order of popcorn comes with 4 different topping choices. Thus;

A number of unique ways that you can order a bag of popcorn are;

N = 3×4 = 12 unique ways
