Answer:

x = 4

Step-by-step explanation:

7.5 + 7.5 = 15

[tex]\frac{x}{8}[/tex] = [tex]\frac{7.5}{15}[/tex]

cross multiply

15x = 60

divide

x = 4

or

since the bigger one is 2x smaller

8/2 = 4

Answer:

A is your correct answer.

1, 3, 5, and 7 are equal to each other and 2, 4, 6, and 8 are equal to each other.

Step-by-step explanation:

Congruent angles are angles that have the same measure. In this example, where two parallel lines are cut by a transversal line, the angles in the same position on the top line and bottom line are congruent. For example, angle 1 and 5 are in the same position, so they have the same measure.

Also, vertical angles (opposite angles, like 5 & 7 in your example) have the same measure.

Answer:

The tree grows 3,14 centimeters per year

Answer: First you have to look at the years and see how much it increase each year. We start by seeing that in 1 year it is 3.14. In two years it will be 6.28. So, the answer each year the tree gets older it is 3.14 that you have to add. Hope it helps.

Answer:

Step-by-step explanation:

Answer:

x = 27, y = 74

Step-by-step explanation:

Hi again :)

Since the angles of 5x + 4 and the one adjacent to x = 14 are corresponding angles, they are equal. That means that (5x + 4) + (x + 14) = 180 degrees.

5x + 4 + x + 14 = 180

6x + 18 = 180

6x = 162

x = 27

Also, the angle (5x + 4) and (2y - 9) are vertical angles, they are equal in value. We know the value of x now, so we'll substitute that in and solve for y.

5(27) + 4 = 2y - 9

135 + 4 = 2y - 9

139 = 2y - 9

148 = 2y

y = 74

As always, lmk if you have questions.

Answer:

The equation of a right triangle is given by a2 + b2 = c2, where either a or b is the height and base of the triangle and c is the hypotenuse. Using the Pythagorean Theorem, finding the missing side of a triangle is pretty simple and easy. The two special right triangles include: 45°; 45°; 90° Triangle.

Answer:

You will pay $18.69 for a item

Step-by-step explanation:

if you buy an item at $74.75 with 75% discount, you will pay 74.75 - 56.0625 = 18.69 dollars.

Answer:

$299

Step-by-step explanation:

The discount is 75%, so the sale price represents 25% of the original price.

25% : $74.75

(multiply both sides by 4 to get 100%)

100% : $299

Answer:

Answer:

6 units^2

Step-by-step explanation:

[tex]a^{2} +b^{2} =c^{2}[/tex]

[tex]3^{2} +b^{2} =5^{2}[/tex]

[tex]9+b^{2} =25[/tex]

[tex]b^{2}=16[/tex]

Answer: (1, 10)

Step-by-step explanation:

When you translate, you add or subtract the value you are moving to each coordinate

(6,7) left 5 would be -5 to the x coordinate and 3 up would be +3 to the y coordinate.

6-5=1

7+3=10

new point is (1,10)

moving left 5 units is subtracting 5 from the x value:

6-5 = 1

Moving up 3 units is adding 3 to the y value:

7 + 3 = 10

The answer is (1,10)

Answer:

Lien: $26300 Her husband: $24700

Step-by-step explanation:

x+(x+1600)=51000

2x+1600=51000

2x=49400

x=24700

Her husband earned 24700

24700+1600=26300

Lien earned 26300

Answer:

325 boys

Step-by-step explanation:

The ratio 5:7 represents 5+7=12 students. If we were to proportionalize this ratio to 780 students, we would multiply the ratio by 65/65 since 780/12=65.

Therefore, you have (5*65)/(7*65)=325/455 as your ratio. This means that there are 325 boys in the school

Answer:

15,000

Step-by-step explanation:

1/3 times 45,000 = 15,00

The number of blue pens produced at the factory in a week when 45,000 pens are produced is 15,000.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given that,

A factory produces blue pens and black pens.

2/3 of the pens produced at the factory are black.

If T is the total pens produced at the factory, then the number of black pens produced is 2/3 T.

Number of blue pens = T - 2/3 T = 1/3 T

Given that,

Total pens produced = 45,000

Equation to find the number of blue pens is,

x = 1/3 × 45,000

Solving,

x = 15,000

Hence the number of blue pens produced is 15,000.

3. 1+5v+v= 1+6v

Like: 5+1

You are doing this with n:

10-7=3 and this with numbers:

-7-8=-15 (both negative again)

6.a-2+1+4a= 5a-1

Like this: 4+1=5 and -2+1=-1

7. 8(x+10)= 8*x+8*10= 8x +80

8. 8(1+6p)= 8*1+8*6p= 8+48p
