If c = 18, what is 2 x (74 - c)?

Answers

Answer 1

Answer: First you substitute 18 into c and solve what's inside the paranthesis which is 56. Distribute the 2 to 56 and you should be getting 112 as your answer. 2x(74-c)=112 if c=18.

Answer 2

Answer: 2 x (74 - 18)
74-18=56
2x(56)
112x

The conversion of square feet to square yards can be represented by direct variation. Three square yards are equivalent to 27 square feet. Let y represent the number of square yards and x the number of square feet. Then y varies directly with x.What is the constant of variation?

Answers

Let y represent the number of square yards
Let x the number of square feet.
Then y varies directly with x.

y = kx
where k is the constant of variation.
y = 3 yards^2
x = 27 feet^2

3 = k(27)
k = 3/27
k = 1 yard^2 /9 feet^2

So the constant of variation is 1 yard^2 /9 feet^2.

Answer:

constant of variation is 1/9 and equation is y=1/9x

Step-by-step explanation:

3/27 = 1/9

No, you can clearly see that angle4 is an obtuse angle while angle2 is more of a right angle. Since 3 and 5 are vertical angles means that 180-angle3=angle4 BUT 180-angle3=angle2 AND angle 1. So they are not vertical angles.

Vertical angles are pairs of each other.

Answers

X= 25 because you set both equations equal to each other so 6x - 2 = 4x + 48 then to find the measure of the angle you plug in the value of X. So angle A = 6(25) -2 = 148

Answer:

x = 25 ; m∠A = 148°

Step-by-step explanation:

∠A ≅ ∠B (alternate exterior angles)

(6x - 2)° = (4x + 48)°

2x = 50

x = 25

m∠A = 6(25) - 2 = 148°

Answer:

C. Associative Property of Multiplication

Step-by-step explanation:

The associative property of multiplication is a.(b.c) = (a.b).c

The associative property of multiplication is true for all the real numbers.

Let me show you an example.

Let's take a = 2, b= 5 and c = -2

a.(b.c) = 2.(5.-2)

=2(-10)

= -20

(a.b).c = (2.5).-2

= 10.-2

= -20

You can see a.(b.c) = (a.b).c

-20 = -20

So the associative property of multiplication holds good.

Given: 3.(x.y) = (3.x).y

It is an example of "associative property of multiplication"

Even if we change the brackets and multiply the terms, the result will be the same.

It's Associative Property of Multiplication.
