(-3f+9)-(2-6f) what’s the answer

Answer: 640 students.

Step-by-step explanation:

given data:

number of student chosen to attend by the mayor = 160

amount this student represents of the total population = [tex]\frac{1}{4}[/tex]

solution:

since [tex]\frac{1}{4}[/tex] was chosen which is 160 this means that [tex]\frac{1}{4} is \geq 160[/tex]

therefore;

[tex]\frac{1}{4} = 160\\[/tex]

multiply both sides by 4

[tex]\frac{1}{4} . 4 = 160 .4\\= 640[/tex]

the least number of students that attend melvins school is 640.

Upon drafting an equation based on the information provided and solving it, it is concluded that Steph earns £36 by selling the plain scones.

An equation is a combination of numbers, variables, functions, or often symbols according to a peculiar rule. It consists of expressions and equality sign(=).

Let's assume that Steph earns x from selling cheese scones then she earns 4x from selling fruit scones and 3x from selling plain scones.

The total amount she earns by selling all the scones is 96.

So,

x + 4x + 3x = 96

8x = 96

x = [tex]\frac{96}{8}[/tex]

x = 12

The amount she earns by selling plain scones = 3 × 12 = 36.

So, she makes £36 by selling the plain scones.

Answer: 50 smoothies in one hour

Step-by-step explanation:

1.5 / 3 = 0.5

75 / 3 = 25.

0.5 x 2 = 1.

25 x 2 = 50.

Margo can make 50 smoothies in One hour.

Hope this helps!

Answer:

Margo can make 50 smoothies in one hour.

Step-by-step explanation:

Let's look at the hours first. Margo can make 75 smoothies in 1.5 hours. 1.5 divided by 3 is 0.5. Then, 0.5 x 2 is 1. Now that we have the number of hours we need (1 hour), we have to do the exact same thing to the amount of smoothies.

75 divided by 3 is 25. Then, 25 x 2 is 50 smoothies.

So, Margo can make 50 smoothies in one hour.

Answer:

Olivia sold 16 chocolate bars and Emily sold 32.

Step-by-step explanation:

Let's set the amount of chocolate bars Olivia sold as x.

Since Emily sold twice as many, she would have sold 2x chocolate bars as a result.

Therefore, since the total is 48 bars, the equation would be [tex]x + 2x = 48[/tex].

[tex]x + 2x = 48[/tex]

[tex]3x = 48[/tex]

[tex]x = 16[/tex]

Hence, Olivia sold 16 chocolate bars.

Substituting the new value into the equation, we would find that Emily had sold 2x = 2(16) = 32 chocolate bars.

Checking the answer, we would find that (16 + 32) chocolate bars is indeed 48 chocolate bars, which fits the question.

Finally, we can arrive at the conclusion that Olivia sold 16 chocolate bars and Emily sold 32.

Answer:

The terminal point is (1, 0) ⇒ D

Step-by-step explanation:

In the unit circle, Ф is the angle between the terminal side and the positive part of the x-xis.

In a unit circle

∵ Ф = 2π radians

∵ 2π radians = 360°

→ By using the 1st rule above

∴ The terminal point is (1, 0)

Answer:

c

Step-by-step explanation:

Since the perimeters are equal, then equate the perimeter expressions, that is

4(x - 2) = 6([tex]\frac{1}{2}[/tex] x + 5) ← distribute parenthesis on both sides

4x - 8 = 3x + 30 ( subtract 3x from both sides )

x - 8 = 30 ( add 8 to both sides )

x = 38

Substitute x = 38 into either of the 2 perimeter expressions

perimeter = 4(x - 2) = 4(38 - 2) = 4 × 36 = 144 in → c

Answer:

The measure of all the angles are;

45°, 135°, 45°, and 135°

Step-by-step explanation:

The given parameters are;

The ratio of two adjacent angles of the parallelogram = 1:3

Let x represent one of the adjacent angles, and let y represent the other adjacent angle

Given that two adjacent angles of a parallelogram are supplementary, we have;

x + y = 180°

x:y = 1:3

Therefore, y = 3 × x = 3·x, which gives;

x + 3·x = 180°

4·x = 180°

x = 180°/4 = 45°

y = 3 × x = 3 × 45° = 135°

Given that opposite interior angles of a parallelogram are equal, we have, the measure of all the angles are;

45°, 135°, 45°, and 135°.

Answer:

equation is then y= -5x + 9

Step-by-step explanation:

First the equation of a line is y=mx+b

if parallel the slope is the same

so m= -5

y= -5x +b

plug in point (1,4) into equation to find by

4= -5(1) + b

b=9

equation is then y= -5x + 9
