Answer:

jackson is 12

Step-by-step explanation:

let the age be represented by x

jackson is 2 times older than shelly so

2x is jackson’s age and x is shelly’s age

since the sum of their ages is 18 then:

2x + x = 18

solve:

3x = 18 ➔ divide by 3 on both sides

x = 6

so now we know shelly is 6

jackson is 2 times older than her so:

2(6) = 12

hope this hello and hope it is right

Answer:

12

Step-by-step explanation:

since we know that Jackson is 2x Shelly - we can use trial and error.

for instance,

let's suppose Shelly is 6; that means that Jackson must be 12 (6 x 2)

we can check this answer by adding the two;

12 + 6 = 18

therefore, Jackson is 12

Hi!

Let's start with the facts:

Therefore:

[tex]\frac{m}{4}=43[/tex]

Now, we have an algebraic equation. In order to solve, we must multiply both sides by 4 so that way m is by itself.

[tex]\frac{m}{4}*4=43*4[/tex]

[tex]m=172[/tex]

I believe it is 32.

Step-by-step explanation:

32 doubled would be 64 and if you added 4 it would become 68.

Answer:

Solution,

Let the number be x

Now we have,

(x × 2)+4=68

2x=64

x=32

Answer:

Ratio of e : f is 13 : 10

Step-by-step explanation:

area of square E = e x e = e² cm²

area of square F = f x f = f² cm²

The area of square E is 69% greater than the area of square F

If the area of square F = 100%

then the area of square E = 100% + 69% = 169%

So the ratio of  e² : f²  =  169 : 100

square root both sides:   e : f = √169 : √100

so e : f = 13 : 10

Answer:

w = 13 m

l = 32

Step-by-step explanation:

let 'w' = width

let '2w+6' = length

P = 2l + 2w

90 = 2(2w+6) + 2w

90 = 4w + 12 + 2w

90 = 6w + 12

78 = 6w

w = 13

length = 2(13) + 6  → 32

l = 32

check:

2(13) + 2(32) should equal 90

26 + 64 = 90

90 = 90 checks out

Answer:

Step 1: Calculate the mean of the data—this is \muμmu in the formula.

Step 2: Subtract the mean from each data point. These differences are called deviations. Data points below the mean will have negative deviations, and data points above the mean will have positive deviations.

Step 3: Square each deviation to make it positive.

Step 4: Add the squared deviations together.

Step 5: Divide the sum by the number of data points in the population. The result is called the variance.

Step 6: Take the square root of the variance to get the standard deviation
