Answer:
x = 9Step-by-step explanation:
[tex] \frac{x}{3} = \frac{2x + 3}{7} [/tex]
Cross multiply
That's
7x = 3( 2x + 3)
Multiply the terms
That's
7x = 6x + 9
Subtract 6x from both sides
We have
7x - 6x = 6x - 6x + 9
Simplify
We have the final answer as
x = 9Hope this helps you
1. Conrad spent $48 on art supplies. The canvas for each of his paintings is an additional $2. He plans to sell his paintings for $10. a. Write an equation that could be used to find the number of paintings (p) he will need to sell to break even.
Thanks
The equation for break even is 8P = 48
What is an Equation ?An equation is an expression that states the equality of two things expressed in different form.
In the given question
Conard spent $48 for art supplies
Canvas costs $2
He plans to sell his painting for $10
∴ Without the canvas his paintings costs $(10 - 2)
= $8
So, no. of paintings (P) to break even he needs to sell
8P = 48
P = 6
∴ Conard needs to sell 6 paintings to break even.

The population of Austin, Texas, was about 494,000 at the beginning of a decade. The population increased by 3% each year. Write an exponential growth model that represents the population y (in thousands) t years after the beginning of the decade. Find and interpret the y-value when t = 10.
Answer:
y(t) = 494 (1.03)^t
y(10) = 663,89
Step-by-step explanation:
An increase in population by 3% each year means that at the end of each year, the population is 1.03 times what it was at the start of the year
This increase in population continues for t years
Exponential growth model that represents the population y (in thousands) t years after the beginning of the decade is
y(t) = 494 (1.03)^t
Where,
y = population
t = number of years
Find y when t = 10
y(t) = 494 (1.03)^t
y(10) = 494 (1.03)^10
= 494 ( 1.3439)
= 663.8866
Approximately y(10) = 663.89
This means that after 10 years from when the population was 494,000, it increased to 663,89.

Please help solve the equation 1.5x-0.5=x+3.25
Answer:
x = 7.5
Step-by-step explanation:
Step 1: Subtract x from both sides.
1.5x−0.5−x=x+3.25−x
0.5x−0.5=3.25
Step 2: Add 0.5 to both sides.
0.5x−0.5+0.5=3.25+0.5
0.5x=3.75
Step 3: Divide both sides by 0.5
0.5x ÷ 0.5 = 3.75 ÷ 0.5

The change in kinetic energy (in joules) as a horse accelerates from canter to gallop is found using the expression 1/2 times 350 times (12 2 Minus 6 2
Answer:
[tex]\mathtt{\Delta K.E = 10500 \ J}[/tex]
Step-by-step explanation:
Given that:
the expression for the change in kinetic energy = [tex]\dfrac{1}{2} \times 350 \times ( 122 -62)[/tex]
Recall that
Kinetic energy K.E = [tex]\dfrac{1}{2}mv^2[/tex]
where,
m = mass of the horse
v = velocity of the horse
The change in kinetic energy between two instant times can be expressed by the relation
[tex]\Delta K.E = K.E_2 - K.E_1[/tex]
[tex]\Delta K.E =\dfrac{1}{2}mv^2_2- \dfrac{1}{2}mv^2_1[/tex]
[tex]\Delta K.E =\dfrac{1}{2}m(v^2_2-v^2_1)[/tex]
where;
m = 350
[tex]v_2[/tex] = 122
[tex]v_1[/tex]= 62
[tex]\Delta K.E =\dfrac{1}{2} \times 350 \times (122-62)[/tex]
[tex]\Delta K.E =\dfrac{1}{2} \times 350 \times (60)[/tex]

Answer:
3.
Step-by-step explanation:
1/x = (x+3)/(2x^2), where x ≠ 0.
Cross-multiply to give 2x^2 = x(x+3).
2x^2 - x^2 - 3x = 0
x^2 - 3x = 0
x(x - 3) = 0

10⁴ can also be written as 10×10×10×10= 10000
so, 5.3 × 10000= 53000
Scientific notations are the way through which a very small or a very large number can be written in shorthand. The value of 5.3×10⁴ in standard form is equal to 53,000.
What are Scientific notations?Scientific notations is the way through which a very small or a very large number can be written in shorthand. In scientific notations when a number between 1 and 10s is multiplied by a power of 10.
For example, 6,500,000,000,000 can be written as 6.5e+12.
Given the numerical value 5.3×10⁴ which is needed to be written in the standard form, therefore, we can write,

Mia is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 2 points. What would be Mia's test score (out of 50) if she got 3 questions wrong? What would be her score if she got x questions wrong?
Answer:
Mia's test score is 44 if she got 3 questions wrong.
Mia's test score is (50-2x) if she got x questions wrong.
Step-by-step explanation:
It is given that, Mia is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 2 points.
If she got 3 questions wrong, then
Deducted marks [tex]=2\times 3=6[/tex]
Marks obtained by Mia = Total marks - Deducted marks
[tex]=50-6[/tex]
[tex]=44[/tex]
So, Mia's test score is 44 if she got 3 questions wrong.
If she got x questions wrong, then
Deducted marks [tex]=2\times x=2x[/tex]
Marks obtained by Mia = Total marks - Deducted marks
[tex]=50-2x[/tex]
So, Mia's test score is (50-2x) if she got x questions wrong.
