The weight of the jar after solving equation simultaneously is w=0.

A set of two or more first-degree equations with two or more connected unknowns is known as a system of linear equations.

A system of equations is solved by determining the value of each unknown until the system's equations are all satisfied. That is, it is necessary to find the values of the unknowns so that, when substituted, they will produce the suggested solution in both equations.

j+w=1.5

2j+w=3

Simultaneously solving gives

w=0

the weight of jar is 0.

The total number of muffins in 4 boxes by the arithmetic equation is (4 × 10) + (4 x 3) = 52.

The series where the common difference between any two next words stays constant is known as an arithmetic sequence. Let's review what a sequence is. A collection of numbers that follow a pattern is called a sequence.

Every term in an arithmetic sequence is created by adding a specified number (either positive, negative, or zero) to the term before it.

the number of boxes of muffins is 4

The muffins in each box is 13

so the total number of muffins in 4 boxes is 4 x 13

⇒ 4 x (10 + 3)

⇒ (4 x 10) + (4 x 3) = 52

Answer:

Question 1: 29

Question 2: 50

Question 3: AD≅BC

Step-by-step explanation:

question 1: Since it's a parallelogram opposite sides are equal.

4x+5=5x-1   add one to both sides

4x+6 =5x subtract 4x from both sides

6 = x

So AD is equal to 5(6) - 1 = 30-1 =  29=AD

Question 2: Since diagonals in a parallelogram bisect each other AE = EC

So...

5x+5 = 8x- 7 add 7 to both sides

5x+12 = 8x subtract 5x from both sides

12=3x divide both sides by 3

4=x

AC= 5(4) + 5 + 8(4) - 7

AC= 20 + 5 + 32 - 7

AC= 50

Question 3: Lines can only be congruent, represented by ≅, not equal which is represented by =. Values can be equal.

By using the elimination method you get the answer  line AD ≅ line BC

The closest to the number of yards of ribbon Mario had altogether will be ;

⇒ 11 yards

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.

Given that;

Mario had 8 1/5 yards of ribbon for a project.

And, Sue gave him 2 3/4 more yards of ribbon.

Now,

Since, Mario had 8 1/5 yards of ribbon for a project.

And, Sue gave him 2 3/4 more yards of ribbon.

Hence, Total ribbon for the project Mario have = 8 1/5 yards + 2 3/4 yards

                                                                        = 41/5 + 11/4

                                                                        = (164 + 55) / 20

                                                                         = 219 / 20 yards

                                                                         = 10.95 yards

                                                                         ≈ 11 yards

Thus, Total ribbon for the project Mario have = 11 yards

Step-by-step explanation:

Answer:

The interval of minutes that the middle 95% of customers have to wait is between 24 and 44 minutes.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean of 34 minutes, standard deviation of 5 minutes.

Interval of minutes that the middle 95% of customers have to wait.

Within 2 standard deviations of the mean. So

34 - 2*5 = 24 minutes.

34 + 2*5 = 44 minutes.

The interval of minutes that the middle 95% of customers have to wait is between 24 and 44 minutes.

[tex]\implies \boxed{\red{\sf ( x +1)^2 = \dfrac{1}{4}}} [/tex]

Step-by-step explanation:

Given :-

And we need to write the equation by completing the square. Here's the step by step explanation .

Step 1: Make the coefficient of x² as 1 :-

[tex]\implies \dfrac{4x^2}{4} + \dfrac{8x}{4} + \dfrac{3 }{4}= 0 [/tex]

Step 2: Rewrite the equation :-

[tex]\implies x^2 + 2x +\dfrac{3}{4}= 0 [/tex]

Step 3: Add 1² to both sides :-

[tex]\implies x^2 + 2x + 1^2+\dfrac{3}{4}= 0 + 1^2 [/tex]

Step 4: Rewriting in whole square form:-

[tex]\implies ( x +1)^2 = 1 - \dfrac{3}{4} [/tex]

Step 5: Simplify the RHS :-

[tex]\implies ( x +1)^2 = \dfrac{4- 3}{4} [/tex]

Step 6: The required form of equⁿ :-

[tex]\implies ( x +1)^2 = \dfrac{1}{4} [/tex]

Hence the equation by rewriting it by completing the square is ( x + 1)² = 1/4 .

The quadratic equation that models the situation is

h(t) = - 4.9t² + 60.

A quadratic equation is a equation that is of the form -

y = f{x} = ax² + bx + c

Given is that the function h(t) = - 4.9t² + h₀ gives the height (h), in meters, of an object (t) secs after it falls from an initial height h₀. The table shows data for a pebble that fell from a cliff as -

TIME (t)     HEIGHT (h)

1                   55.1

2                  40.4

3                  15.9

The given function is -

h(t) = - 4.9t² + h₀

For the point (1, 55.1), we can write as follows -

55.1 = - 4.9 x 1 x 1 + h₀

h₀ = 55.1 + 4.9

h₀ = 60

So, we can write the function as -

h(t) = - 4.9t² + 60

Therefore, the quadratic equation that models the situation is

h(t) = - 4.9t² + 60.

Answer:

Step-by-step explanation:

A'(-2, -3) would result if A (2, -3) was reflected over the x axis. Point (2,3)'s representation under the x-axis is (2,-3). from the y-axis P image (-a,b).

Changing the sign of the value on the opposite axis, in this case the y-value, is all that is required to reflect a point such as (-2,3) across the x-axis in a question. As a result, this location has a y-value of 3. A positive number, this. A negative sign produces a result of -3.

While the Y coordinate remains the same when you reflect across the Y-axis, the X coordinate changes sign. Determining the reflection of (2, 3) across the Y-axis is therefore (-2, 3). The Y-coordinate of each point must be negative while reflecting across the X axis, but the X value must remain constant.

Therefore the correct answer is option a ) A'(-2, -3)

Therefore , the solution to the given problem is the equation of the midline is: y = M+m /2 .

An equation is a mathematical formula that connects two assertions using the equal sign (=) to denote equivalence. In algebra, an equation is a mathematical statement that establishes the equality of two mathematical expressions. For instance, an equal sign separates the components 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula is used to express the connection between two phrases on either side of a letter. Frequently, there is just one variable, which is also the symbol. for example, 2x - 4 = 2.

Here,

The midline equation is y = M+m /2

when a function has: o a max M AND a min m or o (if it does not have extrema) a bound above M and a bound below m, where M is the minimum bound above and m is the maximum bound below.

When one of the following conditions is true for a function, even though it has a bound below, there is no midline (even if it has a bound above)

It is solely constrained from above (or below)

Any line is midline if a function has the values (-∞, +∞)

Therefore , the solution to the given problem is the equation of the midline is: y = M+m /2 .
