OLEASE HELPP ILL GIVE 30 points

Answer:

A) 12-10

B)36+225

Step-by-step explanation:

A) 3x4=12, 5x2= 10= 12-10

B) 3x2=6x6=36, 3x5=15x15=225=36+225

For x = 3 and y = 5 the values of the given expressions are (a) 4x - 2y = 2 and (b) 2x² + 3y² = 93.

Substitution is a mathemaical technique for replacing variables with specific or covnient values according to the context.

When the values of variables are given to solve an equation we just have to replace those numerical values in place of the given variables.

Given, x = 3 and y = 5.

∴ 4x - 2y is,

= 4(3) - 2(5).

= 12 - 10.

= 2.

And

2x² + 3y².

= 2(3²) + 3(5²).

= 2(9) + 3(25).

= 18 + 75.

= 93.

Answer:

The value of b = -2.7

Step-by-step explanation:

Given

As  the equation is given by

[tex]-5=b-2.3[/tex]

To determine

Solve the equation for b

Given the equation

[tex]-5=b-2.3[/tex]

switch the sides

[tex]b-2.3=-5[/tex]

Add 2.3 to both sides

[tex]b-2.3+2.3=-5+2.3[/tex]

Simplify

[tex]b=-2.7[/tex]

Therefore, the value of b = -2.7

Step-by-step explanation:

A pack of pens costs 8 dollars at the store. you decide to buy three packs of them the tax is three dollars. so your total is 27 dollars.

alternatively:

You have 27$ to spend on pens. you know the tax will be 3$, and that each pack of pens costs 8$. what is the maximum amount of packs of pens you can buy?

Answer:

For High School A, let [tex]S_A(t)[/tex] denote the number of students after [tex]t[/tex] years. Define [tex]S_B(t)[/tex] analogously.

Then [tex]S_A(t) = 850 + 35t[/tex] and [tex]S_B(t) = 700 + 60t[/tex].

After 6 years the number of students in both high schools would be the same.

Step-by-step explanation:

For High School A, let [tex]S_A(t)[/tex] denote the number of students after [tex]t[/tex] years. Define [tex]S_B(t)[/tex] analogously.

Since we start out at 850 students at High School A and it is growing by 35 students every year, we must have that [tex]S_A(t) = 850 + 35t[/tex].

Since we start out at 700 students at High School B and it is growing by 60 students every year, we must have that [tex]S_B(t) = 700 + 60t[/tex].

Setting the two equations equal to each other, we see that [tex]850+35t=700+60t\\850-700=60t-35t\\25t=150\\t=6[/tex]

So after 6 years the number of students in both high schools would be the same.

Answer:

128

Step-by-step explanation:

Let's start by figuring out the last side of the triangle

we can use the pathagoryous theroem and get

11.9²+x²=16.9²

Solve this and get x=12

Let's now compute the area of the triangle

b*h*.5

12*11.9*.5=71.4

So 71.4 is the area of the triangle

we now need to find the area of the semi circle.

to do this we are going to find the area and then divide it by 2

We know that the length is equal to 12 which means that the radius is 6

so we have

π6²/2

which is 56.55

We add the 71.4+56.55= 127.94 which rounds to 128

Answer:

212.758

Step-by-step explanation:

Find the semi-circle first, the diameter is 16.9 ft.

To find area:

Formula:

pi x radius x radius x 1/2

16.9 ÷ 2 = 8.45 (radius)

22/7 x 8.45 x 8.45 = 224.407 (Circle)

224.407 ÷ 2 = 112.203 (Semi circle)

Find the triangle:

1/2 x base x height or length x base x height

But for now, we will use the first one.

1/2 x 16.9 x 11.9 = 100.555

Now add them up.

100.555 + 112.203 = 212.758

(I don't know what units you to put for your answer since I don't learn American mathematics, so it's up to you)

thats the answer

p+x= 12x

Answer:

4 12/18, simplified is 4 6/9

Step-by-step explanation:

You change the fractions to improper fractions so 10 1/2 to 21/2 and 2 1/4 to 9/4. Since we can't divide, we change 9/4 to 4/9 and multiply. 21 times 4 is 84 and 2 times 9  is 18.  Since that is an improper fraction, we have to change it to a mixed number. 18 can go into 84 4 times, and 18 x 4 is 72. 84 minus 72 is 12 so the final answer is 4 12/18 (simplified 4 6/9)

Answer:

6, 7, 2, 3

Step-by-step explanation:

supplementary means that two or more angles add together to equal 180 degrees

a straight line equals 180 degrees so the intersecting of a line creates two angles that are supplementary. That means <5 is supplementary with 6 and 7.

<5=<1 because the lines intersecting it are parrell. Using the same thinking process for angle 1 as above, it is supplementary with 2 and 3. and since 1 is equal to 5 it is also supplementary to 2 and 3.

Step-by-step explanation:

To find the missing leg, we need to use a^2 + b^2 = c^2.

Let's call the missing leg a, and then substitute the numbers the other numbers

a^2 + 12^2 = 13^2

Simplify

a^2 + 144 = 169

To solve, subtract 144 from both sides (169-144)

a^2 = 25

This means that a squared is 25; to find a, we need to find the square root of 25.

a = 5

Your answer is 5.

Answer:

5m

Step-by-step explanation:

set it up

[tex]12^{2}[/tex]+[tex]a^{2}[/tex]=[tex]13^{2}[/tex]

do what you know

equation becomes: 144+[tex]a^{2}[/tex]=169

subtract both sides by 144

equation becomes [tex]a{2}[/tex]=25

square root both sides

equation becomes: a=5

Answer:

7 hours

Step-by-step explanation:

We are given that

At sunset, the temperature=-5 degrees Fahrenheit

Each hour, temperature falling=2degrees Fahrenheit

We have to find time taken to reach the temperature -19° F.

Let x be the time time taken to reach the temperature -19° F

According to question

[tex]-5+x(-2)=-19[/tex]

Where we taking 2 negative because temperature decreases.

[tex]-5-2x=-19[/tex]

[tex]-5+19=2x[/tex]

[tex]14=2x[/tex]

[tex]x=\frac{14}{2}[/tex]

[tex]x=7[/tex]

Hence, it will take 7 hours for the  temperature to reach -19° F.
