Answer:

x = 11(13/14)

Step-by-step explanation:

3/5(x – 7/10) = -31/4

open the bracket:

3/5 * x – 7/10 = -31/4

3/5 * –7x/10 = -31/4

3/5 + 31/4 = 7x/10

(12+155)/20 = 7x/10

167/20 = 7x/10

cross multiply:

140x = 1670

x =1670/140

x = 11(130/140)

x = 11(13/14)

The value of x is 1/5.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

3/5 (x − 7/10)= −3 1/4

Now, Solving for x

3/5 ( x- 7/10 )= 13/4

x- 7/10 = -13/4 x 5/3

x- 7/10 = -65 /12

x= -65/12 + 7/10

x= 24/ 120

x= 1/5

hence, the value of x is 1/5.

Answer: 1/(x^6)

Step-by-step explanation:

(x^-2)^3=

(x^(-2*3))=

(x^(-6))=1/(x^6)

Answer:

1/\(x^{6}\)

Step-by-step explanation:

(x^-2)^3

If you have parentheses around an exponent, you multiply them together.

x^-6

Change it to reciprocal so it is 1/\(x^{6}\)

Proof:

\(x^{-2}\) × \(x^{-2}\) × \(x^{-2}\) = \(x^{-2 - 2 - 2}\) = \(x^{-6}\)

Answer:

B.) 1020 mi ^2

Since the next largest city is Anchorage, Alaska you would just subtract Juneau's land area from Anchorage's land area.

Answer:

The perimeter of the stained glass semi-circle is 3π feet.

Step-by-step explanation:

The perimeter of a semi-circle is half of the circumference of the full circle with the same diameter.

The circumference of a circle with diameter 3 feet is:

C = πd = π(3) = 3π feet

Therefore, the circumference of the full circle is 3π feet, and the circumference of the semi-circle is half of that:

C(semi-circle) = 1/2(3π) = 3/2π feet

However, the stained glass semi-circle has a curved edge, so we need to add the length of that edge to the perimeter. The curved edge of a semi-circle is half of the circumference of the full circle, or:

C(curved edge) = 1/2(2πr) = πr, where r is the radius of the circle

Since the diameter of the circle is 3 feet, the radius is half of that:

r = d/2 = 3/2 feet

So the curved edge of the stained glass semi-circle is:

C(curved edge) = π(3/2) = 3/2π feet

Adding this to the straight edge perimeter, we get:

Perimeter = C(semi-circle) + C(curved edge)

= (3/2π) + (3/2π)

= 3π feet

Therefore, the perimeter of the stained glass semi-circle is 3π feet.

Answer:

B and (3.5,5)

Answer: idfk

Step-by-step explanation:

The correct answer is (D) -2x - 8.

To simplify the expression -1/3 ( 6x + 15 ) - 3, we can first apply the distributive property to the term in parentheses:

-1/3 ( 6x + 15 ) - 3 = -1/3 * 6x - 1/3 * 15 - 3

Then we can simplify using the properties of multiplication and division:

-1/3 * 6x - 1/3 * 15 - 3 = -2x - 5 - 3

Finally, we can combine like terms:

-2x - 5 - 3 = -2x - 8

The correct answer is therefore (D) -2x - 8.✅

Answer:

For A: The first function has a greater ROC

For B: The first function has a negative slope

Step-by-step explanation:

Explication for A:

We already know that the R.O.C. (slope) is 2 for the first function, so all we need to do is substitute the values in the table into the following formula: y2-y1/x2-x1

after substituting: (-3-(-6))/(0-(-1))

simplify 3/1=3, since the ROC is 3, the second equation has a greater ROC than the first

Explanation for B:

The first function described is f(x)=20-3.5x

This is because the y intercept is the starting point, or how much money she has in the gift card. She spends 3.5 dollars per week, so we add a variable to represent the number of weeks, and its negative since she is spending, not earning. We also know that the slope is negative since y is decreasing as x is increasing, on the table.

The second function described is c(m)=5x+10

This is because the equation represents the total cost of renting a calculator, so both terms are positive.

Answer:

y=5x-3

Step-by-step explanation:

y-7=5(x-2)

Based on the information, it can be inferred that the difference in the circumference of the two circles is 6.31 cm.

To calculate the circumference of a circle we must apply the following formula:

According to the previous formula, we must replace R with the radius of each of the radii of both circles as shown below:

So, to find the difference of the circumferences of both circles we must subtract the smaller number (circumference of the small circle) from the larger number (circumference of the large circle).

According to the above, the difference of the circumferences would be 6.31 cm.

R = Radius of the circle.

According to the previous formula, we must replace R with the radius of each of the radii of both circles as shown below:

Alright, sweetheart. Your answer is C. I'm gonna tell you how so you can do it on your own from now on.

Step-by-step explanation:

Slope is the number of times you go up over the number of times you go over. This slope is a positive slope because up and right are both positive directions. Look at where the line crosses over on -3. Go up till you see where the line intersects again and then count the number of spaces you have to go over to get to the next intersection.
