Answer: the answer to #3 is a= 4

Step-by-step explanation:

I have to answer each question with a separate box

Answer:

3) a = 4

4) m = 10

5) x = 2

6) (correct as is)

9) t = 14

Step-by-step explanation:

3:

Step 1: Add 4 to both sides.

[tex]8+4=3a-4+4[/tex] [tex]12=3a[/tex]

Step 2: Divide both sides by 3.

[tex]12/3 = 3a/3[/tex] [tex]a = 4[/tex]

4:

Step 1: Subtract 9 from both sides.

[tex]m/5 + 9 - 9 = 11 - 9[/tex] [tex]m/5 = 2[/tex]

Step 2: Multiply both sides by 5.

[tex]m/5 * 5 = 2 * 5[/tex] [tex]m = 10[/tex]

5:

Step 1: Subtract 13 from both sides.

[tex]13+7x-13=27-13[/tex] [tex]7x=14[/tex]

Step 4: Divide both sides by 7.

[tex]7x/7 = 14/7[/tex] [tex]x=2[/tex]

6: (correct as is)

9:

Step 1: Subtract 5t from both sides.

[tex]42+5t-5t=8t-5t[/tex] [tex]42=3t[/tex]

Step 2: Divide both sides by 3.

[tex]42/3=3t/3[/tex] [tex]t=14[/tex]

14)  2x - 5 = 7

15) 4x - 1 = 11

16) 6x - 6 = 12

17) x/3 + 10 = 12

18) 2x + 7 = 1

19) 9 + x/7 = 11

20) 8(n - 3)

Step-by-step explanation:

The quotient of x and 2 = x ÷ 2 = x/2

The product is the result of multiplying two or more other numbers

The sum is the result of adding two or more numbers

The difference is the result of subtracting one number from another

13) 7 + x/2 = 10

14)  2x - 5 = 7

15) 4x - 1 = 11

16) 6x - 6 = 12

17) x/3 + 10 = 12

18) 2x + 7 = 1

19) 9 + x/7 = 11

Freddie needs to buy 3 dozen cookies for a party. The first 20 cookies cost $0.27 each. The rest cost $0.17 each.
How much will Freddie spend on cookies?
$2.72
$5.40
$8.12
$9.72

Answers

Answer:

$8.12 is the total amount Freddie will spend on the cookies.

Step-by-step explanation:

3 dozen = 36 cookies

20 x $0.27= $5.4

we still need 16 more cookies

16 x $0.17= $2.72

add $5.4 and $2.72 together. which = $8.12

Answers

Answer:  D) 8

Explanation:

The green, light blue, and red bars all indicate scores that are 70 or higher.

We add up the heights of those bars to find out how many people passed.

green bar = height of 2light blue bar = height of 5red bar = height of 1

So 2+5+1 = 8 people passed.

Unfortunately 2 people (dark blue bar) got below 70 so they didn't pass.

Answer:

x = 25

scalene, acute

Step-by-step explanation:

Sum of the interior angles of a triangle = 180°

[tex]\implies (2x+11)+(3x-7)+(2x+1)=180[/tex]

[tex]\implies 2x+11+3x-7+2x+1=180[/tex]

Collect like terms:

[tex]\implies 2x+3x+2x+1+11-7=180[/tex]

Combine like terms:

[tex]\implies 7x+5=180[/tex]

Subtract 5 from both sides:

[tex]\implies 7x=175[/tex]

Divide both sides  by 7:

[tex]\implies x=25[/tex]

Substituting found value of [tex]x[/tex] into the three angle expressions:

∠A = (2 x 25) + 11 = 61°

∠B = (3 x 25) - 7 = 68°

∠C = (2 x 25) + 1 = 51°

This is a scalene triangle as it has three different angles and three different side lengths (non-congruent).

It is also an acute triangle as all interior angles are less than 90°

x=25 because a triangle is 180° so 2x+11+3x-7+2x+1=180

(SAT Prep) If the lengths of two sides of a triangle measure 8 and 13 what could the length of the third side measure
(A) 6

(B) 21

(C) 3

(D) 4
Hint its not D.

Answers

Answer:

A)6

Step-by-step explanation:

Use the triangle inequality theorem, which states that the third side of a triangle can not be greater than or equal to the sum of the other two sides, and can be no less than the or equal to the difference of the two other sides.

The sum is 8+13=21

The difference is 13-8=5

So if we call our third side x, then

[tex]5

If the lengths of two sides of a triangle measure 8 and 13 units, using triangle inequality theorem, the length of the third side could be 6 units.

What is triangle inequality theorem?

The triangle inequality theorem describes the relationship between the three sides of a triangle. According to this theorem, for any triangle, the sum of lengths of two sides is always greater than the third side.

Given the two sides be 8 and 13 units.

Let the third side be x units.

First,

8 + 13 > x

21 > x

x < 21

Second,

8 + x > 13

x > 5

Third,

13 + x > 8

True for all values of x.

So,

5 < x < 21

From the given options, only 6 satisfies our condition.

Answers

Answer:

BC > AC and BC < AB.

Step-by-step explanation:

Given that,

To construct △ABC with m∠A=30°, m∠B=60°, and  m∠C=90°.

We have to find,

The statements about the triangles are true.

According to the question,

In △ABC

This means that the side opposite to the right angle in the triangle is AB.

Since, the side opposite to the right angle is the hypotenuse and is the longest side of the triangle, thus AB cannot be shorter than any other side of the triangle.

Then, BC < AB.

And, In the triangle △ABC ,

tan60° =

tan60° =

By comparing the equations,

Then, BC > AC

Hence, The required correct statement in △ABC are BC > AC and BC < AB

You have been asked to build a scale model of your school out of toothpicks. Imagine your school is 30 feet tall. Your scale is 1 ft:1.26 cm. If a toothpick is 6.3 cm tall, how many toothpicks tall will your model be?

Answers

Answer: If your school is 30 feet tall and 1 feet is 1.26 cm,
you would multiply 30 and 1.26 to get the height
of the scale model which is 37.8 cm. Then, if
each toothpick is 6.3 cm, you would take 37.8
and divide it by 6.3 to get the number of
toothpicks you need to build the school, which
is 6.
The model will be 6 toothpicks tall.
6 tooth picks would be the answer to your question

Start with parentheses, so 6+4. 10.

Then your equation is 5 x 10 - 1.

Then Multiplication, since there are no exponents- 5 x 10 = 50.

Then since there’s no division, skip to addition.

Since there is no addition either go to subtraction, 50 - 1.

50 - 1 = 49.
