Ten years from now Sam will be twice as old as she was three years ago.How old is she now?

Answers

Answer 1

Answer:

is ther any information about how old he will be in ten years from now

Step-by-step explanation:

Answer 2

Sam's current age is 16 years old based on the provided condition.

Ten years from now, Sam will be twice as old as she was three years ago. Let's represent Sam's current age as x. According to the given condition:
Age after ten years = x + 10
Age three years ago = x - 3
Given that the age after ten years will be twice the age three years ago:
x + 10 = 2(x - 3)
Solving for x:
x + 10 = 2x - 6
x = 16

Therefore, Sam is currently 16 years old.

∠C and ∠D are vertical angles with m∠C=−3x+58 and m∠D=x−2 .

What is m∠D ?

Answers

vertical angles are equal

-3x + 58 = x - 2
-3x - x = -2 - 58
-4x = - 60
x = -60/-4
x = 15

m < D = x - 2....15 - 2 = 13 <====
m < C = -3x + 58....-3(15) + 58 = 13

Answer:

m<D is [tex]13^{0}[/tex]

Step-by-step explanation:

Vertically opposite angles are said to be equal angles, thus;

m<C = m<D

So that,

-3x + 58 = x -2

-3x - x = -2 -58

- 4x = - 60

x = [tex]\frac{- 60}{- 4}[/tex]

x = 15

Thus,

m< D = x - 2

= 15 - 2

= [tex]13^{0}[/tex]

Therefore, m<D is [tex]13^{0}[/tex]

Si S es el 150% de T, qué tanto por ciento de T es (S + T)?

Answers

Final answer:

If S is 150% of T, then to find what percentage (S + T) is of T, we calculate (S + T) / T * 100. By substituting S = 1.5T into the equation, we determine that (S + T) equals 250% of T.

Explanation:

If S is the 150% of T, this implies that S is 1.5 times T (since 150% can be expressed as 1.5 in decimal form). To express S as a percentage of T, we can set up the equation S = 1.5T.

Now, we are asked to find what percentage of T is (S + T). To find this, we simply add S and T together: S + T = 1.5T + T = 2.5T. Now, to express this sum as a percentage of T, we divide the sum by T and then multiply by 100.

So, ((S + T) / T) * 100 = (2.5T / T) * 100 = 2.5 * 100 = 250%. Therefore, (S + T) is 250% of T.

To find the percentage that (S + T) is of T, we first need to find the value of S and T. The given information states that S is 150% of T. This means that S = 1.5T. To find (S + T), we substitute the value of S in terms of T: (1.5T + T) = 2.5T.

Now, to find the percentage that (S + T) is of T, we divide (S + T) by T and multiply by 100: ((2.5T / T) imes 100) = 250%.

Therefore, (S + T) is 250% of T.

5n-12=3n+4 equals what

Answers

5n-12=3n+4
2n-12=4
2n=16
n=8

Take add 12 to both sides:
5n-12+12 = 3n+4+12
= 5n = 3n+16

Then take away 3n from both sides:
5n-3n = 3n+16-3n
= 2n = 16

Then divide both sides by 2
2n/2 = 16/2
= n = 8

how to do 8c+6j=5p solve for c and plz show how you got it

Answers

The answer is c=3j/4+5p/8 how I got I was by subtracting 6j from both sides then divide

8c + 6j = 5p

We're simply just trying to get c onto it's own side, so we must get everything onto the other side of c.

So, subtract 6j from both side.s

8c = 5p - 6j

Then, divide both sides by 8.

8c ÷ 8 = (5p - 6j) ÷ 8

Simplify.

c = 5p/8 - 6/8j

Simplify.

c = 5/8p - 3/4j → [tex]c = \frac{5}{8} p - \frac{3}{4} j[/tex]

6/x +3=
3x- 6=
6 (x+3)=

tip: 6/x is a fraction

Answers

We don't know exactly what x is, so the best we can do is simplify these expressions. For 6/x+3, we know that both 6 and 3 are factors of 3, so using the distributive property, 3*2/x+3*1=3*(2/x+1). For 6(x+3), we can use the distributive property to get 6*x+6*3=6x+18. Good luck on the middle expression (I'd recommend using a similar strategy to the one I used), and feel free to ask any questions!

Step-by-step explanation:

I couldnt put a division sign so i jsut but the word and yea hope that helps

Final answer:

The percent increases for the given quantities are 6%, 60%, and 12% respectively. To find these, subtract the original quantity from the new quantity to find the amount of increase, then divide this by the original quantity and multiply by 100.

Explanation:

In order to find the percent increase, you can follow this formula:

Step 1: Subtract the original quantity from the new quantity. This gives you the amount of increase.Step 2: Divide the increase by the original quantity.Step 3: Multiply result by 100 to get the percent increase.

Now, let's solve the questions :

a. Original Quantity: 100, New Quantity: 106

Amount of increase = 106 - 100 = 6

Percent increase = (6/100)*100 = 6%

b. Original Quantity: 10, New Quantity: 16

Amount of increase = 16 - 10 = 6

Percent increase = (6/10)*100 = 60%

c. Original Quantity: 50, New Quantity: 56

Amount of increase = 56 - 50 = 6

Percent increase = (6/50)*100 = 12%

The perimeter of a geometric figure is the sum of the lengths of its sides. If the perimeter of the pentagon to the right (five-sided figure) is 96 meters, find the length of each side. 2 of the sides= 2.5x

Answers

Final answer:

The length of each side of the pentagon is 19.2 meters.

Explanation:

To find the length of each side of the pentagon, we need to divide the perimeter of the pentagon by 5, since a pentagon has 5 sides. If the perimeter is 96 meters, each side would have a length of 96/5 = 19.2 meters.

Josh walked a total of 5 miles today. First he walked 1 mile from his house to the park then he walked laps around the 3/4 mile loop trail at the park. Finally he walked back home. Howany laps did Josh walk around the trail?

Answers

Josh walked 4 laps around the trail.

To find out how many laps Josh walked around the trail, we first need to calculate the distance he walked from his house to the park and back, and then subtract that from the total distance.

Distance from home to park: Josh walked 1 mile from his house to the park.

Distance from park to home: He also walked 1 mile back home.

Now, let's calculate the total distance Josh walked around the trail:

Total distance walked = Total distance - (Distance from home to park + Distance from park to home)

Total distance walked = 5 miles - (1 mile + 1 mile)

= 5 miles - 2 miles

= 3 miles

Now, we know that Josh walked laps around a 3/4 mile loop trail, and he walked a total of 3 miles. To find out how many laps he walked, we divide the total distance by the distance of each lap:

Number of laps = Total distance / Distance per lap

= 3 miles / (3/4 mile)

= 3 miles * (4/3)

= 4 laps

So, Josh walked 4 laps around the trail.

Now, subtract 66 (Number of three point shots and one point shots) from 102 (Total amount of shots)

102 - 66 = 36

36 ÷ 2 = 18
