Given:ST=3x=3 and TU=2x=9 what is the value of ST

Answer:

-3

Step-by-step explanation:

12x+15=3x+12

12x-3x=-15+12

9x =-3

9÷-3

x=-3

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

the equation of a line is:  y = mx+b

Where:

m is the slope, and

b is the y-intercept

Replace m with -3 and replace b with 4, in the equation y=mx+b.

[tex]m = -3\\b =4\\\\y =mx+b\\\\y =-3x+4[/tex]

Answer:

28

Step-by-step explanation:

[tex]number \: of \: wooden \: blocks \\ = \frac{volume \: of \: box}{volume \: of \: one \: wooden \: block} \\ = \frac{11 \times 10 \times 7}{3 \times 3 \times 3} \\ = \frac{770}{27} \\ = 28.51 \\ [/tex]

Thus, there would be 28 full wooden blocks in the box.

Answer: 28 wooden blocks

Step-by-step explanation: First you must find the volume of the box with the formula: L × W × H so, 10 × 11 × 7 = 770 inches³. Second you must find the volume of the wooden blocks with the formula: x³ ( 'x' is the value of the side of the cube ) so, 3 × 3 × 3 = 27 inches³. Now you can divide the volume of the box by the volume of the wooden block = 770 ÷ 27 = 28.518...*

* Always only count the whole numbers.

Answer:

5

Step-by-step explanation:

-6b> -8-22

-6b> -30

b> -30/-6

b>5

Answer:

So we have this inequality:

[tex]-6b + 22 > -8[/tex]

We substract 22 on both sides:

[tex]-6b > -30[/tex]

Now, we divide both sides by -6 and we change the sign, as, when we multiplicate or divide by a negative number we always have to do it:

[tex]b < \frac{-30}{-6}[/tex]

[tex]b < 5[/tex]

So we know b < 5, so the biggest integer b can represent is 4. Note that the solution is any number which is smaller than 5.

Answer:

x² + 18xi - 81

Step-by-step explanation:

FOIL - First, Outside, Inside, Last

Step 1: Write out expression

(x + 9i)²

Step 2: Expand

(x + 9i)(x + 9i)

Step 3: FOIL

F - x²

O - 9xi

I - 9xi

L - 81i²

Step 4: Combine

x² + 18xi + 81i²

Step 5: Simplify

i² = -1

x² + 18xi + 81(-1)

x² + 18xi - 81

Answer:

[See Below]

Step-by-step explanation:

✦ In this figure there are two shapes; A triangle and a square. So you'll need to know the area formula for both:

  ✧ Square ∼ s² (Side Squared)

  ✧ Triangle ∼ ½ × b × h

✦ So now just solve for each area:

  ✧ Square ∼ 15² = 225

  ✧ Triangle ∼  ½ × 15 × 3 = 22.5

✦ Now add each area together to get the total area:

  ✧ 225 + 22.5 = 247.5

Answer:

I'm pretty sure it $2.96

Answer:

option c) $ 2.96

Step-by-step explanation:

15% = 15 /100 = 0.15

Let last year's price = $ x

x + 15% of x = $ 3.40

x + 0.15*x = 3.40

x + 0.15x = 3.40    {Add like terms}

1.15x = 3.40   {Divide both sides by 1.15}

1.15x/1.15=3.40/1.15

x = 2.956

Last year's price = $ 2.96

Conclusion

Reason

Answer: -1

Step-by-step explanation:

Given by your question

2(3x-1)≥4x-6

Distributive property to take off the parentheses

2×3x-2×1≥4x-6

6x-2≥4x-6

Subtract 4x on both sides (Subtractive property of equality)

6x-2-4x≥4x-6-4x

2x-2≥-6

Add 2 on both sides (Addition property of equality)

2x-2+2≥-6+2

2x≥-4

Divide 2 on both sides (Division property of equality)

2/2 x≥-4/2

x≥-2

----------------------------------------------------------------------------

Looking at the options you've provided.

-10 INCORRECT, it is not greater or equal to -2

-5 INCORRECT, it is not greater or equal to -2

-3 INCORRECT, it is not greater or equal to -2

-1 CORRECT, it is greater than -2

Answer:

6 ounces of oil

Step-by-step explanation:

Well the first salad dressing is probably 8 ounces because 2+6 = 8

Then we must find out how large this recipe compares to the original

24/8 = 3

So we need all the ingredients to be tripled to keep the same ratio of 2:6

The new dressing has 2*3 ounces of oil and 6*3 ounces of vinegar

which equals 6 ounces of oil and 18 ounces of vinegar.

Hope this helps!

$4,000 in the 10% per year account

$11,000 in the 12% per year account

Answer:

4000 for 10% a year

11000 for 12% a year

Answer: OPTION 3. -7

Step-by-step explanation:

Given

-52=-4x-5(-2x+2)

Distributive property (REMEMBER you need to change signs)

-52=-4x-5×(-2x)-5×2

-52=-4x+10x-10

Combine like terms (-4x and 10x)

-52=6x-10

Add 10 on both sides

-52+10=6x-10+10

-42=6x

Divide 6 on both sides

-42/6=6/6x

x=-7

Hope this helps!! :)

Please let me know if you have any question

x = -7

[tex]-52=-4x-5(-2x+2)\\-52=-4x+10x-10\\-52=6x-10\\-42=6x\\-7=x[/tex]

to make sure, plug x in the equation:

[tex]-52=-4(-7)-5(-2(-7)+2)\\-52=28-5(14+2)\\-52=28-70-10\\-52=28-80\\-52=-52[/tex]

The sales price would be $36.00

How I got this answer:

Discount: (45 x 20)/100 = $9.00 the nine dollars is your discount.

Final pricing:

45 - 9.00 = $36.00 when you subtract the cost with the discount you should get thirty-six dollars.

Answer:

A scale factor is a number which scales, or multiplies, some quantity.

Step-by-step explanation:

i.e: this shape multiplied by a scale factor of 2. Usually solved by a ratio

As shadow is directly propotional to height, we can say that,

Height/Shadow =k, where k is a constant.

So, in case of electric pole,

1410=k→(1)

In case of tree,

HT15=k→(2), where HT is height of tree

So, from (1) and (2),

1410=HT15

HT=14∗1510=21m

So, height of tree is 21 meters.
