Answer 1

Answer:

x = 16

4x = 64

Step-by-step explanation:

The sum of the exterior angles of any polygon is 360°

Add the given angles and solve for x

93 + 46+ 3x + 62 + 4x +47 = 360

7x + 248 = 360

7x = 360 –248

x = 16

4(16) = 64

Bo' sister Anna is 3/4 his age minus 1 year. She is 11 years old.Write an equation to find Bo's age.

Answers

Answer: 16 years

Step-by-step explanation:

Let's Bo's age be represented by x.

Since Bo' sister Anna is 3/4 his age minus 1 year and she is 11 years old, this can be formed into an equation as:

(3/4 × x) - 1 = 11

3/4x - 1 = 11

3/4x = 11 + 1

3/4x = 12

Multiply both side by 4/3

x = 12 × 4/3

x = 16

Bo's age is 16 years

Answer:

x = 12 × 4/3

if 100 grams of meat costs 30 pesos,how much does 8 kilograms costs

Solution:
Answer:
Check:

Answers

Solution:

First, we need to find out the amount for one kilogram. Since 100 grams = 30 pesos, and 1000 grams = 1 kilogram, we need to multiply it by 10.

30 x 10 = 300

Now we have the amount for 1 kilogram. Now in order to get the amount for 8 kilograms, we need to multiply it by 8.

300 x 8 = 2400 pesos

Answer:

The answer is 2,400 pesos.

Check:

30 x 10 = 300 So 300 pesos for a kilogram

300 x 8 = 2400 So 2400 pesos for 8 kilograms.

Answer:

uuuummmmmm go to khanacademy but i think 140

Step-by-step explanation:

Three numbers add up to 210. The second number is 10 more than the first and the third number is 3 times the first. Find the numbers by modelling the problem using an algebraic equation.

Answers

Answer:

I. First number, a = 40.

II. Second number, b = 50.

III. Third number, c = 120.

Step-by-step explanation:

Let the three numbers be a, b and c respectively.

Given the following data;

Translating the word problem into an algebraic equation, we have;

a + b + c = 210

b = a + 10

c = 3a

Substituting the value of b and c into the equation, we have;

a + a + 10 + 3a = 210

5a + 10 = 210

5a = 210 - 10

5a = 200

a = 200/5

a = 40

To find the value of b;

b = a + 10

b = 40 + 10

b = 50

To find c

c = 3a

c = 3*40

c = 120

A line is parallel to y = 4x + 1 and
intersects the point (-2,-5). What is the
equation of this parallel line?
y = [?]x + [

Answers

Answer:

y = 4x+3

Step-by-step explanation:

The equation in point slope form is expressed as y - y0 = m(x-x0)

m is the slope

(x0, y0) is the point on the line

If a line is parallel to y = 4x + 1, the slope of the line m = 4

Substitute m = 4 and the point (-2, -5) into the equation above;

y - (-5) = 4(x - (-2))

y+5 = 4(x+2)

200 - 400 = -200

x=17 - hope this helps!

To solve this we are using the Pythagorean Theorem which is c^2=a^2+b^2.

In this case the c (hypotenuse) is x. Our equation will look like this:

x^2=15^2+8^2
x^2=225+64
x^2=289
We do the square root to undo ^2
x = 17
