Which answer describes the solution to each equation a. 2x+6-x=1/3(3x+18

Answers

Answer 1

Answer: 1., simplify
x+6=x+6
0=0
true
x's cancel out eventually so therefor there are infinite soluions
C

2.
1/8x=12
x=96
A 1 solution
A

3. times 3 both sides
3x+3=3x+3
0=0
infinite solitons
C

4. 7x+9=7x+5
9=5
false
no soluiton

1.C
2.A
3.C
4. B

To solve this, all we need to do is substitute the values of x and y at which they are the same into each equation and see if it holds true.

A. $(y)/(x) = (1)/(2)$

$(-8)/(4) = (1)/(2)$

$-2 = (1)/(2)$

Since this is not true, we can scratch choice A off our list.

B. $(y)/(x) = -2$

$(-8)/(4) = -2$

$-2 = -2$

This is true, so choice B is one of the correct answers.

C. $-2x = y$

$-2 (4) = -8$

$-8 = -8$

This equation also holds true, so choice C is also correct, but let us do the final option just for the sake of completion.

D. $x = 2y$

$4 = 2 (-8)$

$4 = -16$

This is obviously not true, so choice D is also false.

The correct answer choices are B and C.
Hope that helped! =)

varies directly, so x times a number = y
let z be that number
y= zx
-8=4z
z=-2
y=-2x
which is equals to y/x=-2 and -2x=y , so its B and C

Explain how you know whether to add or subtract when you use the distributive property to multiply

Answers

Distributive property of multiplication has two expressions:

1. $a\cdot (b+c)=a\cdot b+a\cdot c$

2. $a\cdot (b-c)=a\cdot b-a\cdot c$

If you use these formulas from the left side to the right side, you should see for the sign in the brackets: "+" - use addition, "-" - use subtraction. If you use these formulas from the right side to the left side, you should also take into account sign between $a\cdot b$ and $a\cdot c$ : for "+" - use addition in brackets and for "-" - use subtraction in brackets.

The correct answer is:

We treat the addition or subtraction signs inside the parentheses as positive and negative signs and follow our integer rules.

Explanation:

Take for example -3(x+y). The distributive property tells us to take -3*x + -3*y; we have a positive multiplied by a negative, which is a negative, and another positive multiplied by a negative, which is again a negative. This gives us -3x+-3y, or -3x-3y.

If we consider the sign of the value outside the parentheses as well as the signs of those inside, we can be sure to use the write operation sign.

Which value of x will make the equation2x-30=6 true?

Answers

18 should be the value of x to make the equation true.

2x - 30 = 6

2x = 6 + 30
2x = 36
2x/2 = 36/2
x = 18

to check:
2x - 30 = 6
2(18) - 30 = 6
36 - 30 = 6
6 = 6

What is the mixed number for 4.8

Answers

it is 4 $(8)/(10) or (4)/(5)$

4.8 in a mixed number is 4 4/5 because 4.8 in a fraction is 48/10, simplified 24/5. Then you divide 24 by 5 and it will give you 4 4/5!

s?
@ 0.45 cup
Ⓡ 0.04 cup
☺ 0.54 cup

What is the answer

Answers

Answer:

Option C: 0.04 is the correct answer.

Step-by-step explanation:

Given that:

cups of sugar used = 7.5

cookies = 14 dozen

As we know that 1 dozen cookies equal 12 cookies so,

14 dozen cookies = 14* 12 = 168 cookies

Now,

we have to find the rate of cups of sugar per cookie, So:

Rate = cups of sugar / total cookies

By putting values:

Rate = 7.5/ 168

By simplifying we get

Rate = 0.04464

By rounding it off to nearest hundred:

Rate = 0.04

Hence the rate of cups of sugar per cookie is 0.04

i hope it will help you!
