Answer quick please! <3
Answer:
sorry if this is wrong
Step-by-step explanation:
Maggie = X
Brother = 2X-3 <--- 3 years younger than twice her age.
2x - 3 + x = 24 <--- the sum of their ages is 24
3x - 3 = 24
3x = 27
x = 9
Maggie is 9.
Brother is 2*9 - 3 = 18 - 3 = 15
Answer:
15

Part A: The sun produces 3.9 ⋅ 1033 ergs of radiant energy per second. How many ergs of radiant energy does the sun produce in 1.55 ⋅ 107 seconds? (5 points)
Part B: Which is the more reasonable measurement of the diameter of a human hair:
1.8 ⋅ 10−2 mm or 1.8 ⋅ 102 mm? Justify your answer. (5 points)
Using the multiplication operation, the Number of ergs produced in [tex]1.55 \times 10^{7} [/tex] is [tex] 6.045 \times 10^{40} \: ergs [/tex]
Eggs produced per second = [tex]3.9 \times 10^{33} [/tex] Number of seconds = [tex]1.55 \times 10^{7} [/tex]Total number of ergs produced can be calculated thus :
Ergs per second × number of seconds[tex]3.9 \times 10^{33} \times 1.55 \times 10^{7} = 6.045 \times 10^{33+7} = 6.045 \times 10^{40} \: ergs [/tex]
Therefore, the Number of ergs produced in [tex]1.55 \times 10^{7} [/tex] is [tex] 6.045 \times 10^{40} \: ergs [/tex]
B.)
Due to the very small measure of the diameter of the human hair, a measure of [tex]1.8 \times 10^{2} mm[/tex] would be too large, Hence, the value [tex]1.8 \times 10^{-2} mm[/tex] would be more appropriate

Answer:
Yellow = 2/3(Blue)
Step-by-step explanation:
You only really need the first row of the table since it shows the volume of yellow to the volume of blue.
Before we write the equation we have to find the ratio and to do that we divide.
Divide the amount of yellow by the amount of blue:
3.5/ 5.25 = 0.666 = 2/3
now we can write the eqaution:
Yellow = 2/3(Blue)

Use the Distributive Property to simplify the expression.
1/2(2n+4+6m)
Answer:
n + 3m + 2, or also the same as 1n + 3m + 2
The simplified form of the given expression is [tex]n+2+3m[/tex].
Important information:
The given expression is [tex]\dfrac{1}{2}(2n+4+6m)[/tex].Distributive Property:[tex]a(b+c)=ab+ac[/tex]
We have,
[tex]\dfrac{1}{2}(2n+4+6m)[/tex]
Using the Distributive Property, the given expression can be written as:
[tex]=\dfrac{1}{2}(2n)+\dfrac{1}{2}(4)+\dfrac{1}{2}(6m)[/tex]
[tex]=n+2+3m[/tex]
Thus, the simplified form of the given expression is [tex]n+2+3m[/tex].

Complete the steps to solve the equation.
1/5t + 2 - ____ = 17 - _____
1/5t=______
_____ * 1/5t =______
t=_______
The complete steps are;
⇒ 1/5t + 2 - 2 = 17 - 2
⇒ 1/5t = 15
⇒ 5 * 1/5t = 5 * 15
⇒ t = 75
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or variable raised to the power one.
We have to given some steps of equation.
Now, The complete steps to solve the equation are;
1/5t + 2 - ____ = 17 - _____
Subtract 2 from both sides;
⇒ 1/5t + 2 - 2 = 17 - 2
⇒ 1/5t = 15
Multiply 5 in both sides;
⇒ 5 * 1/5t = 5 * 15
⇒ t = 75
So, The complete steps are;
⇒ 1/5t + 2 - 2 = 17 - 2
⇒ 1/5t = 15
⇒ 5 * 1/5t = 5 * 15
⇒ t = 75
