Answer:

4x+y=17 that the answer  

Step-by-step explanation:

Answer:

-4x-17=y

Step-by-step explanation:

Distribute the -4 into the parenthises. Then subrtract the 1 from both sides.

let

brenda: b

will: 3b

b + 3b = 240

4b = 240

b = 60 lbs (BRENDA)

3b = will

3 (60) = will

180 = WILL

The solution is

The weight of Brenda = 60 pounds

The weight of Will = 180 pounds

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the weight of Brenda be = x

Let the weight of Will be = y

Now , Will weighs three times as much as Brenda

Substituting the values in the equation , we get

y = 3x   be equation (1)

And , the weight of Will + weight of Brenda = 240 pounds

So , x + y = 240   be equation (2)

Substituting the value of y from equation (1) in equation (2) , we get

x + 3x = 240

On simplifying the equation , we get

4x = 240

Divide by 4 on both sides of the equation , we get

x = 60 pounds

So , the weight of Brenda is 60 pounds

Substitute the value of x in equation (1) , we get

y = 3x

y = 3 x 60

y = 180 pounds

So , the weight of Will is 180 pounds

Hence , the weight of Brenda is 60 pounds and weight of Will is 180 pounds

Answer:

x = -6

Step-by-step explanation:

Answer:

x=-6

Step-by-step explanation:

14=-(x-8)

14=−x+8(Distribute)

flip equation:

−x+8=14

Subtract 8 from both sides

−x+8−8=14−8

−x=6

divide by -1 both sides

x=-6

Answer: chemical decomposition produced by passing an electric current through a liquid or solution containing ions. In chemistry and manufacturing, electrolysis is a technique that uses direct electric current to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell. Electrolysis is used in industry for the production of many metals and non-metals (e.g., aluminium, magnesium, chlorine, and fluorine). Electrolysis is commonly employed for coating one metal with another. The method of coating one metal with another using an electric current is called electroplating.

Answer:

138.5°

Step-by-step explanation:

Since the peach pie is a circle, we have a total angle of 360°.

We need to determine what fraction of the total pie of 13 peaches is the 5 peaches contained in Joe's slice.

This is number of peaches in Joe's slice/total number of peaches in pie = 5/13. To find the angle Joe's slice measures, we multiply 5/13 by 360°.

So, 5/13 × 360°

= 0.3846 × 360°

= 138.46°

≅ 138.5° to the nearest tenth of a degree

Answer:

m = 810 movies

Step-by-step explanation:

6,840 = 3(1740) + 2m

6,840 = 5,220 + 2m

Subtract 5,220 on both sides

1,620 = 2m

Divide each side by 2

m = 810

Answer:

b = -12

Step-by-step explanation:

First isolate b by subtracting 2 from both sides: b/4 = -3

then multiply both sides by 4 to find b: b = -12

Answer:

b= -12

Step-by-step explanation:

b/4 + 2 = -1

Subtract 2 from both sides

b/4 = -3

Multiply both sides by 4

b= -12

Answer:

4 bottles of Water

Step-by-step explanation:

First, we need to find how much each water costs. So, I created this equation below.

9/12=?

The answer to the equation is .75, or 75 cents.

So, we can now make yet another equation to find the amount to buy with 3 dollars.

3/.75=?

The answer to that equation is 4.

Thus, the answer is 4 bottles of water.

5b=2f

Step-by-step explanation:

Priya uses [tex]7\dfrac{1}{2}[/tex] cups of floor to make 3 loaves of banana bread.

Andre will follow the same recipe. He will make b loaves of banana bread using f cups of flour.

To find the relation between b and f, the steps are as follows :

[tex]\dfrac{\text{cups of flour}}{\text{loaves of banana bread}}=\dfrac{7 \dfrac{1}{2}}{3}\\\\=\dfrac{\dfrac{15}{2}}{3}\\\\=\dfrac{15}{2}\times \dfrac{1}{3}\\\\=\dfrac{5}{2}[/tex]

It means,

[tex]\dfrac{f}{b}=\dfrac{5}{2}\\\\5b=2f[/tex]

So, the relationship between b and f is "5b=2f".

Answer:

10

Step-by-step explanation:

The measure of an angle∠I  is 10 degrees between the 450 cm and 640 cm sides.

The Law of Cosines (also called the Cosine Rule) is defined as it relates all three sides of a triangle with an angle of a triangle.

c² = a² + b² − 2ab cos(C)

The cosine rule, also known as the law of cosines, relates all 3 sides of a triangle with an angle of a triangle. it relates the lengths of the sides of a triangle to the cosine of one of its angles.

In the given triangle ΔHIJ,

Sides:

h = 450 m

i = 210 m

j = 640 m

The angle of ∠I  is 10 degrees between the 450 cm and 640 cm sides.

According to the cosine rule,

j² = h² + i² − 2ab cos(I)

Substitute the values in the Cosine Rule,

450² = 210² + 640² - 2(210)(640)cos(I)

After solving we get the value of  angle ∠I :

∠I = 9.56038°

Rounded to the nearest degree.

∠I = 10°

Thus, the measure of an angle∠I  is 10 degrees.
