There are three strategies used to resolve structures of equations: graphing, substitution, and elimination. To solve a gadget via graphing, you honestly graph the given equations and locate the factor(s) in which they all intersect. The coordinate of this point will provide you with the values of the variables that you are fixing.

To remedy a machine of linear equations without graphing, you may use the substitution technique. This method works by way of solving one of the linear equations for one of the variables, then substituting this price for the same variable in the different linear equation and solving for the other variable.

Answer:

40 minutes

Step-by-step explanation:

Day 1) Monday --> 10 min.

Day 2) Tuesday --> 15 min.

Day 3) Wednesday --> 20 min.

Day 4 )Thursday --> 25 min.

Day 5) Friday --> 30 min.

Day 6) Saturday --> 35 min.

Day 7) Sunday --> 40 min.

Using the formula for the nth term in an arithmetic sequence, we find that Jasmine will practice for 40 minutes on the 7th day.

The problem can be solved by using arithmetic progression. The first term of this sequence is the amount of time Jasmine spent practicing on Monday, which is 10 minutes. The common difference is the amount of time she adds to her practice every day, which is 5 minutes. To find out how long she will practice on the 7th day, we can use the formula for the nth term in an arithmetic sequence: a + (n-1)d.

Plugging in our values, we find:
10 + (7-1)*5 = 10 + 30 = 40.

So, Jasmine will practice for 40 minutes on the 7th day.

Answer:

£72

Step-by-step explanation:

Firstly, if half of 96 coins are £1 coins then:

96/2 * 1 = value of half the coins = £48

Now, we simply need to multiply 96/2 by 0.5 to find the value of these coins:

48 * 0.5 = 24

Now we can add the two:

48 + 24 = 72

So the value of the 96 coins are £72.

Answer:

44 hours

Step-by-step explanation:

Decreasing the people by a factor of 2 means we have 3 people

The job takes 6* 22 = 132 people hours

When we decrease the people, it will take more hours

132 people hours = 3 people * t hours

Divide each side by 3

132/3 = 3t/3

44 = t

It will take 44 hours

Answer:

Step-by-step explanation:

We are given that a shade of green is prepared using 2 cups of yellow and 3.5 cups of blue.

We want to make the same shade of green, but lesser quantity. We can assume a smaller value for either of the yellow or the blue colors, and find the corresponding value of the other to figure out the answer.

Let us assume that 1 cup of yellow is mixed with x cups of blue to prepare the same shade of the green. Now we can set up the ratios as shown below:

[tex]\frac{1}{x}=\frac{2}{3.5}\\2x=3.5\\x=1.75[/tex]

Therefore, 1 cup of yellow and 1.75 cups of blue color will also make the same shade of green

Answer:

A). $50.27

Step-by-step explanation:

Add $39.99 and -$10.28 to get $50.27

Final answer:

Julie withdrew $50.27 from her account, which can be calculated by adding her previous balance of $39.99 to the absolute value of her negative current balance, $10.28.

Explanation:

The question asks to determine how much was withdrawn from Julie's bank account, given that her balance went from $39.99 to -$10.28. To do this, we subtract the current balance from the previous balance. So the calculation is $39.99 - (-$10.28).

First, subtracting a negative is the same as adding its absolute value, so the equation can be rewritten as $39.99 + $10.28.

When these two values are added together, we get a total of $50.27. This means that Julie withdrew $50.27 from her account.

Therefore, the correct answer is A). $50.27.

Step-by-step explanation:

Final answer:

To determine 'a' and 'd' for tn = a + (n-1)x, substitute the values of 'n' and 't' into the equations and solve the system of equations.

Explanation:

To determine 'a' and 'd' for tn = a + (n-1)x, we need to find the values of 'a' and 'd' that satisfy both t7 = 3 + 5x and t11 = 3 + 23x.

Step 1: Set up two equations

t7 = 3 + 5x

t11 = 3 + 23x

Step 2: Use the formula tn = a + (n-1)x to substitute the values of 'n' and 't' in the equations.

a + 6d = 3 + 5x (equation 1)

a + 10d = 3 + 23x (equation 2)

Step 3: Solve the system of equations.

Subtract equation 1 from equation 2: (a + 10d) - (a + 6d) = (3 + 23x) - (3 + 5x)

Cancel out the 'a' terms and simplify the 'd' and 'x' terms: 4d = 18x

Divide both sides by 18: d = 4.5x

Substitute the value of 'd' in equation 1 to solve for 'a': a + 6(4.5x) = 3 + 5x

Expand and simplify the equation: a + 27x = 3 + 5x

Subtract 5x from both sides: a + 22x = 3

Subtract 22x from both sides: a = 3 - 22x

So, the values of 'a' and 'd' are a = 3 - 22x and d = 4.5x.

To find the probability that the first grape candy chosen from the bag will be, at least, the third candy chosen overall, you multiply the probability that a candy is not grape (0.74) by itself (since we're considering two independent events, both candies not being grape). The answer is 0.5476.

The subject of this question is probability which is a branch of mathematics. You're looking to find the probability that the first grape candy drawn from a bag of Sandy's Sours will be, at least, the third candy chosen overall.

Given that 26% of the candies are grape, the probability that the first candy drawn is not grape is 1 - 0.26 = 0.74 (or 74%). Since we're looking for the first grape candy to be the third candy drawn or later, we need the first two candies to be not grape.

The probability that the first candy drawn is not grape is 0.74. Because each candy draw is an independent event (the result of one draw does not affect the results of any other draws), the probability that neither the first nor the second candy drawn is grape is 0.74 * 0.74 = 0.5476 (or 54.76%).

B) y = x – 7.5

-6.75 = 0.5 - 7.5

-6.75 ≠ -7

C) 2y = x + 13

2 x -6.75 = 0.5 + 13

-13.5 ≠ 13.5

y = 0.5x – 7

-6.75 = 0.5 x 0.5 -7

-6.75 = -6.

Step-by-step explanation:

x^2 + 3x - 18 = 0

(x+6)(x-3)=0

x=-6 x=3

i had this on my book so i just wanted to help.

Final answer:

The quadratic equation x^2 + 3x - 18 = 0 can be solved using the quadratic formula, resulting in two solutions, x = 3 and x = -6.

Explanation:

To solve the quadratic equation x^2 + 3x - 18 = 0 using the quadratic formula, we must first identify the coefficients a, b, and c in the standard form ax2 + bx + c = 0. In our equation, a = 1, b = 3, and c = -18. Substituting these values into the quadratic formula gives us:

x = [-b ± √(b^2 - 4ac)] / (2a)

By substituting the values we have:

x = [-(3) ± √((3)^2 - 4(1)(-18))] / (2(1))

Which simplifies to:

x = [-3 ± √(9 + 72)] / 2

x = [-3 ± √(81)] / 2

x = [-3 ± 9] / 2

Therefore, we have two possible solutions for x:

x = (-3 + 9) / 2 = 3

x = (-3 - 9) / 2 = -6

So, the solutions to the equation x2 + 3x - 18 = 0 are x = 3 and x = -6.
