Answer:

t = 4.5

Step-by-step explanation:

Distribute 3 to the parentheses:

3(t + 4) = 25.5

3t + 12 = 25.5

Subtract 12 from both sides:

3t = 13.5

t = 4.5

So, the answer is t = 4.5

Answer:

1/6

Step-by-step explanation:

When subtracting or adding fractions, you always want the denominator (aka the bottom number of the fraction) to be the same number. Since both of your denominators are both the same, we can subtract!

                                                 2/6 - 1/6 = 1/6

Remember that you don't subtract the bottom, just the top. Hope this helped :)

Answer:

y= -1/4x - 6

Step-by-step explanation:

So the point slop form is y = mx + b, where m is the slope : -1/4, and b is the y-intercept (which we don't know yet).

To find b, all you need to do is plug in -1/4 for m and the point (4, -7) for x and y respectively, giving you:

-7 = (-1/4)(4) + b

Then do some algebra shenanigans: multiply -1/4 by 4 to get -1

-7 = -1 + b

then add the 1 to both sides.

b = -6

Then, you can plug the b and the m back into the problem to give you:

y = -1/4x - 6

Answer:

C

Step-by-step explanation:

Point slope form looks like this: [tex]y-y_1=m(x-x_1)[/tex]

We already have our slope (-1/4)

Our [tex]y_1[/tex] is -7 and our [tex]x_1[/tex] is 4

In this case, our equation would be [tex]y-(-7)=-1/4(x-4)[/tex] and the -(-7) would turn into +7

Therefore, the answer is C

Answer:

Indeed, men and women are not the same. They have structural differences in their genetic makeup that make them different and compatible with each other. In addition, they have differences in character, behavior, strength and even emotional sensitivity.

Even the scriptures themselves speak of differences between the two: according to the book of Genesis, the woman was created from the rib of Adam, the first man on earth. With this, the woman, theoretically, has one more rib than the man.

Answer: x = 12, ∠B = 45°

Step-by-step explanation:

Angle A and Angle B are alternate exterior angles meaning that they are equal

5x - 15 = 2x + 21

3x - 15 = 21

3x = 36

x = 12

B = 2(12) + 21

B = 24 + 21

B = 45

Answer:

135ft^2

Step-by-step explanation:

Area of the smaller parallelogram = Base * Height

15 = 3 * height

Height = 15/3

Height = 5ft

Since they are both similar

Height of the big parallelogram = 3(5) = 15ft

Area of the other parallelogram = 9 * 15

Area of the other parallelogram = 135ft^2

Third table is true with 4 rows titled School Play Tickets. The first column is labeled tickets (x) with entries 0, 10, 51, 400 and the second column is labeled money collected (y) with entries 0, 50, 255,2000.

Here, the equation is given as;

y = 5x

Where, x is the number of tickets sold for the school play and y is the amount of money collected for the tickets.

What is linear equation?

A linear equation is an algebraic equation of the form y = mx + b

involving only a constant and a first order (linear) term.

Now, we have the following equation;

y = 5 x

For finding the table that complies with this restriction and also have the corresponding values for x and y.

The third table complies with the given condition and has correct values for the given variables;

⇒ x = 0 then y = 0

⇒ x = 10 then y= 50

⇒ x = 51 then y = 255

⇒ x = 400 then y = 2000

Clearly, Third table is true with 4 rows titled School Play Tickets. The first column is labeled tickets (x) with entries 0, 10, 51, 400 and the second column is labeled money collected (y) with entries 0, 50, 255,2000.

Step-by-step explanation:

The bird food lasts 1½ weeks.

Your birdseed mixture last till 10 and a half weeks.

A fraction that has the numerator higher than or equal to the denominator is said to be an improper fraction.

Given:

You have 5[tex]\frac{3}{4}[/tex] cups of sunflower seeds and 1[tex]\frac{1}{4}[/tex] cups of peanuts for birdseed.

The total mixture,

= 5[tex]\frac{3}{4}[/tex] + 1[tex]\frac{1}{4}[/tex]

= 23/4 + 5/4

= 28/4

= 7 cups.

You use 2/3 of the total mixture each week.

That means,

the number of weeks,

= 7 x 3/2

= 21/2

= 10.5 weeks.

Therefore, the mixture will last till 10 and a half weeks.

Answer:

x = 70°

Step-by-step explanation:

the interior angle which is supplemental to 140° is 40°

the sum of the interior angles of any triangle is 180°

so:

180° = 40° + 2x

subtract 40° from each side of the equation:

2x = 140°

x = 70°

Step-by-step explanation:

This is because the bus can hold up to 40 people so 0 to 40

The solution will be the intersection points thus options A (1,-3) and B (-2,0) will be correct.

The graph is a geometrical representation of a function and can be plotted by taking x's and y's corresponding values within the interval.

For example plot of y = x³ ,y = sinx.

The solution will be the intersection points of both functions.

At the intersection point,

x² - 4 = -x - 2

x² + x - 2 = 0

x² + 2x - x - 2 = 0

x(x + 2) - (x + 2) = 0

(x - 1)(x + 2) = 0

x = 1,-2

At x = 1

y = -1 - 2 = -3 so first intersection is (1,-3)

At x = -2

y = -(-2) - 2 = 0 so second intersection is (-2,0)

Hence "The solution of the given system of equations is (1,-3) and (-2,0)".
