Step-by-step explanation:

Answer:

3/2

Step-by-step explanation:

Answer:

x= 1

y= -2

Step-by-step explanation:

equation (1): y= -3x+1

equation (2): y=x-3

solve the system of equations by substitution:

step1: sub ( x-3 ) for y in equation 1:

y = -3x+1

x-3 = -3x+1

step2: simplify the equation to get x:

(add 3 for both sides)

x = -3x+4

(add 3x for both sides)

4x = 4

(divide 4 from both sides)

x = 1

step3: sub the value of x (x=1) in equation 2:

y = x-3

y = 1-3

step4: solve the equation to get y:

y = -2

Step-by-step explanation:

The value of x for equation x /45 = 3 is 135, value of expression −5.8 + (−2.5) is -8.3, the sale price is $319.20, volume of cube is 125 cubic centimeter, y = x /8 represents a proportional relationship.

An expression is combination of variables, numbers and operators.

1. The given equation is x /45 = 3

Now value of x is 45×3

x=135

3. The expression is −5.8 + (−2.5)

−5.8 −2.5

The value of expression is -8.3

4.To find the sale price  after a 20% discount, we need to subtract 20% of the original price from the original price:

20% of $399 = (20/100) x $399 = $79.80

Sale price = $399 - $79.80 = $319.20

Therefore, the sale price is $319.20.

5.  The side length of cube is 5 cm

Volume = 5³

=125 cubic centimeter

6. y = 8/ x equation represents a proportional relationship

7. 5 ft² is area of the wall will the game board cover

9. The given expression is 5 /8 x 4 /5

20/40

1/2

Hence, the value of x for equation x /45 = 3 is 135, value of expression −5.8 + (−2.5) is -8.3, the sale price is $319.20, volume of cube is 125 cubic centimeter, y = x /8 represents a proportional relationship.

Answer:

4a - 3b + 5 = 5

Step-by-step explanation:

Express the ratios in fractional form

[tex]\frac{a}{3}[/tex] = [tex]\frac{b}{4}[/tex] ( cross- multiply )

4a = 3b ( subtract 3b from both sides )

4a - 3b = 0

Step-by-step explanation:

Answer:

6.82 kg

Step-by-step explanation:

set up a proportion based on 2.2 lbs in 1 kg

2.2/1 = 15/x

cross-multiply:

2.2x = 15

x = 6.82

The value of 15 lb in kg is 6.81 kg.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

We know that;

⇒ 1 lb = 0.454 kg

Hence, We get;

⇒ 1 lb = 0.454 kg

⇒ 15 lb = 15 × 0.454 kg

            = 6.81 kg

Thus, We get;

⇒ 15 lb = 6.81 kg

Answer: 4

Step-by-step explanation:2+4=6 and the highest number of animals is 5

Answer:

b = 5√3 (units)

Step-by-step explanation:

To solve this problem, use the pythagorean theorem, where a^2+b^2 = c^2, a and b are the legs of the triangle and c is the hypotenuse.

In this case, we are finding the missing leg, and we were given one of the legs and the hypotenuse.

a^2+b^2 = c^2 (pythagorean therorm)

5^2+b^2 = 10^2 (substitute one leg and the hypotenuse)

25+b^2 = 100 (square the numbers)

b^2 = 75 (subtract 25 from both sides)

b = √75

b = √25 * √3 (factor out√75)

b = 5 * √3 (find square root of√25)

b = 5√3

Answer:

x = 7

AC = 44

Step-by-step explanation:

Find the diagram attached

According to the parallelogram,

BD = 2BE

5x-3 = 2(2x+2)

5x-3 = 4x+4

5x-4x = 4+3

x = 7

Hence the value of  x is 7

Also AC = 2AE

AC = 2(4x-6)

AC = 8x - 12

AC = 8(7) - 12

AC=  56-12

AC = 44

Hence the measure of AC is 44

Answer:

Step-by-step explanation:

Answer:

a) The length of segment AC is approximately 5.83 centimeters.

b) The angle ACD is approximately 34.5º.

Step-by-step explanation:

a) Since [tex]AB \perp BC[/tex], the length of segment [tex]AC[/tex] is determined by Pythagorean Theorem, that is:

[tex]AC = \sqrt{(5\,cm)^{2}+(3\,cm)^{2}}[/tex]

[tex]AC \approx 5.831\,cm[/tex]

The length of segment AC is approximately 5.831 centimeters.

b) Since [tex]AB \perp BC \perp AD[/tex], the length of segment [tex]AD[/tex] is determined by this Pythagorean identity:

[tex]AD = \sqrt{(3\,cm)^{2}+(5\,cm)^{2}+(4\,cm)^{2}}[/tex]

[tex]AD \approx 7.071\,cm[/tex]

The angle ACD is determined by the following trigonometric expression:

[tex]\cos C = \frac{AC}{CD}[/tex]

[tex]\cos C = \frac{5.831\,cm}{7.071\,cm}[/tex]

[tex]\cos C = 0.825[/tex]

[tex]C = \cos^{-1} 0.825[/tex]

[tex]C \approx 34.448^{\circ}[/tex]

The angle ACD is approximately 34.448º.

Answer: y = (1/3)*x - 7

Step-by-step explanation:

When we have a line:

y = a*x + b

A perpendicular line to this one needs to have a slope s equal to:

s = -(1/a)

Then any line written as:

y = -(1/a)*x + c

is perpendicular to the lines of the form "y = a*x + b"

Then if we have the line:

y = -3*x - 8

The family of perpendicular lines to this one is:

y = -(1/-3)*x + c

y = (1/3)*x + c

where c can be any real number.

Now we also want that this line passes through the point (9, -4)

Then we need to replace x by 9, and y by -4

-4 = (1/3)*9 + c

Now we can solve this for c.

-4 = 9/3 + c

-4 = 3 + c

-4 - 3 = c

-7 = c

Then the line that is perpendicular to the line y = -3x – 8 and that goes through (9, -4) is:

y = (1/3)*x - 7
