I NEED HELP WITH THIS. PLZZZZ HELP!!!!!!!! :(

Answer:

[tex]x=-\frac{17}{28}[/tex]

Step-by-step explanation:

[tex]\frac{1}{4}(4x-1)=-\frac{1}{7}-\frac{5}{7}[/tex]

[tex]x-\frac{1}{4}=-\frac{6}{7}[/tex]

[tex]x = -\frac{6}{7} + \frac{1}{4}[/tex]

[tex]x = -\frac{17}{28}[/tex]

plug [tex]x[/tex] in the equation to make sure of your answer:

[tex]\frac{1}{4}(4x-1)=-\frac{1}{7}-\frac{5}{7}\\\frac{1}{4}(4(-\frac{17}{28}) -1)=-\frac{1}{7}-\frac{5}{7}\\-\frac{17}{28} -\frac{1}{4}=-\frac{6}{7}\\-\frac{6}{7}=-\frac{6}{7}[/tex]

The distributive property is used when you have a value multiplied by 2 values separated by an operation.

For example, if you have x (y + z), then you would use the distributive property to get x (y + z) = xy + xz.

Step 1:

First, let's order the number from least to greatest.

A. -0.31

B. -0.33

C. -0.38

D. -0.29

We could see that A, B, and C's numbers are already from least to greatest, so all we have to do is to move -0.29 (D) up to the top, since -0.29 is the number with the lowest value.

C. -0.38

B. -0.33

A. -0.31

D. -0.29

Step 2:

Let's look at the four number lines. Remember that we already organized the numbers from least to greatest, so the order they go in on the number line is: C, B, A, and D. Since Line C and D Don't follow that rule, we know those are not our answers. Also on line B, C is on the left of -0.4, but C's value is less than -0.4, so B is wrong. We are left with line A.

Line A: C. -0.38, B. -0.33, A. -0.31, D. -0.29

Our answer: Line A

Answer:

B: -0.3

Answer:

Step-by-step explanation:

To construct an equilateral triangle so that segment AB is one of the sides of the triangle we will follow the following steps.

1). Set a distance equal to the segment AB in the compass and draw two arcs on the same side of AB.

2). Join the point of intersection of these arcs to A and B with the help of a straightedge.

3). Hence an equilateral triangle (with all equal sides) is constructed.

Answer:

Step-by-step explanation:

a) P = N 150000

R = 5%

T = 5 years

Plug in the values P,R & T in the  formula

I = PRT

[tex]I=150000*\frac{5}{100}*4\\\\= 1500 * 5 * 4\\[/tex]

I = N 30000

b) I = N 16100

R = 7%

T = 5 years

[tex]PRT = I\\\\P*\frac{7}{100}*5=16100\\\\P=16100*\frac{100}{7*5}[/tex]

P= N 46000

Answer:

[tex] \boxed{ \bold{ \boxed{ \sf{a. \: \: interest \: = \: N \: 30000}}}}[/tex]

[tex] \boxed{ \bold{ \boxed{ \sf{b. principal \: = \: N \: 46000}}}}[/tex]

Step-by-step explanation:

a. Given,

Principal ( P ) = N 150000

Rate ( R ) = 5 %

Time ( T ) = 4 years

Interest ( I ) = ?

Finding the Interest ( I )

[tex] \boxed{ \bold{ \sf{interest = \frac{principal \times time \times rate}{100} }}}[/tex]

⇒[tex] \sf{interest = \frac{150000 \times 4 \times 5}{100} }[/tex]

⇒[tex] \sf{interest = \frac{3000000}{100}} [/tex]

⇒[tex] \sf{interest = N \: 30000}[/tex]

Interest = N 30000

------------------------------------------------------------

b. Given,

Interest ( I ) = N 16100

Time ( T ) = 5 years

Rate ( R ) = 7 %

Principal ( P ) = ?

Finding the principal

[tex] \boxed{ \bold{ \sf{principal = \frac{interest \times 100}{time \times rate}}}} [/tex]

⇒[tex] \sf{ \frac{16100 \times 100}{5 \times 7} }[/tex]

⇒[tex] \sf{ \frac{1610000}{35} }[/tex]

⇒N [tex] \sf{46000}[/tex]

Principal = N 46000

Answer:

x = -5

Step-by-step explanation:

4 + 2(x - 4)= -7(x + 7)

4 + 2x - 8 = -7x - 49

2x - 4 = -7x - 49

2x + 7x = -49 + 4

9x = -45

x = -45/9

x = -5

Answer:

The answer is A, 19/49

Step-by-step explanation:

normally you would do the equation as usual, but if you notice the words (without replacing the first) then that means there will be 24 marbles left.

that means it can't be B C or D because 24 can't be simplified into the denominators 5, 20, or 15

Answer:

Addition Property of Equality.

Inverse property of multiplication.

Step-by-step explanation:

Given the equation:

[tex]7y-15=-29[/tex]

First of all, let us use Addition Property of Equality.

According to the property, if we add a number on both sides of an equality, there is no change in the equality.

In other words, the equality will be same if we add the same number on Left Hand Side and Right Hand Side of the equality.

First of all, let us add 15 on both sides of the equality:

[tex]7y-15+15=-29+15\\\Rightarrow 7y=-14[/tex]

Now, let us Inverse property of multiplication.

i.e. Multiplication of a number with its inverse is equal to 1.

[tex]a\times \frac{1}{a} = 1[/tex]

So, let us multiply the given equation with [tex]\frac{1}7[/tex]

[tex]7y \times \dfrac{1}{7}=-14 \times \dfrac{1}{7}\\\Rightarrow 1y =-2\\\Rightarrow y=-2[/tex]

The properties used are:

Addition Property of Equality.

Inverse property of multiplication.
