Answer:

A

Step-by-step explanation:

3/4*(-4/3) + 1/2 = -1 + 1/2 = -1/2

First, B is not the answer, because if x = 0, the whole equation would've been 0.

A) -4/3 ; -1/2

Replace x and y with the 2 fractions, we have : 3/4 x (-4/3) + 1/2 = -1/2
-1 + 1/2 = -1/2 (true)
So, A is correct

But to make sure, we'll go over C and D also.

C) 4/3 ; 1/2

Replace x and y : 3/4 x 4/3 + 1/2 = 1/2
1 + 1/2 = 1/2 (not true)

So this is not the answer

D) 4 ; 3/2

Replace x and y : 3/4 x 4 + 1/2 = 3/2
3 + 1/2 = 3/2 (not true)

So, A is correct.

The equivalent values for the ratio 2 to 3 to 8 is 28kg, 42kg and 112kg

Given the following parameters

Total weight = 182kg

If the weight is divide in the ratio 2:3:8, th3n the total ratio will be;

total ratio = 2 + 3 + 8

Total ratio = 13

For the ratio of 2;

Portion =2/13 * 182

Portion = 28kg

For the ratio of 3;

Portion =3/13 * 182

Portion = 42kg

For the ratio of 8;

Portion =8/13 * 182

Portion = 112kg

Hence the equivalent values for the ratio 2 to 3 to 8 is 28kg, 42kg and 112kg

Step-by-step explanation:

If a system has at least one solution, it is said to be consistent. If a consistent system has exactly one solution, it is independent. If a consistent system has an infinite number of solutions, it is dependent.

and if it has no solutions (lines are parallel), then it is inconsistent.

I think that information can be easily found on the internet.

so, the first one on the left is consistent independent. it has a unique solution at (-2, 1). the solution is always the crossing point of the lines.

the middle system is consistent dependent. both lines are identical, and so we have infinite many "crossing points" or solutions.

the right system is inconsistent, as 2 parallel lines have no solution at all.

Answer:

Step-by-step explanation:

Plugin j = 5  and k = 3 int he expression,

4.7j - 6.8k = 4.7*5 - 6.8*3

                 = 23.5 - 20.4

                  = 3.1

Answer:

y = ½x + 5

Step-by-step explanation:

slope of the line is : a= (8-5)/(6-0) = ½ it's the coefficient of x too.

y = ax + b → y = ½x + b

consider the point (0,5) → 5 = ½(0) + b → b = 5

so equation of the line is: y = ½x + 5

Answer:

Step-by-step explanation:

(6,8)  ; (0,5)

At y-intercept x is o.

y=intercept = b = 5

Equation of line in slope intercept form: y = mx + b

y = mx + 5

In this, Plugin the values of the point (6 ,8)

8 = 6m + 5

8 - 5 = 6m

3 = 6m

Divide both sides by 6

3/6 = 6m/6

1/2 = m

Equation of the line:

[tex]y = \dfrac{1}{2}x+5[/tex]

Problem 2

Rewrite the fraction 2/3 into 4/6. This is valid because we multiply top and bottom by 2.

2/3 = 4/6

Now compare the fractions for Wednesday and Tuesday in that order. We have 4/6 and 5/6. We can ignore the denominators because they effectively cancel out. The numerators will form the answer.

Problem 6

7% = 7/100 = 0.07

7% of 12,500 = 0.07*12500 = 875

Answer: x = 157

Step-by-step explanation:

[tex]1056=6\left(x+19\right)[/tex]

Switch sides:

[tex]6\left(x+19\right)=1056[/tex]

Divide both sides by 6:

[tex]\frac{6\left(x+19\right)}{6}=\frac{1056}{6}[/tex]

Simplify:

Answer:

f < 1

Step-by-step explanation:

8(3f−6)<−24

Divide both sides by 8. Since 8 is positive, the inequality direction remains the same.

3f−6< [tex]\frac{-24}{8}[/tex]

Divide −24 by 8 to get −3.

3f−6<−3

Add 6 to both sides.

3f<−3+6

Add −3 and 6 to get 3.

3f<3

Divide both sides by 3. Since 3 is positive, the inequality direction remains the same.

[tex]f<\frac{3}{3}[/tex]

Divide 3 by 3 to get 1.

f < 1

Solution:

Note that:

Simplify the inequality to obtain the inequality for f.

The simplified inequality is f < 1.

7. B. 417.6

8. 138.98

Explanation:

6) (7x-5) - (3x-2)

7x-5 - 3x+2

distribute the -1 from the middle into (3x-2) which only changes the signs

7x-5 - 3x+2

collect like terms (7x and -3x) as well as (-5 and 2)

Answer---> 4x-3

7) 0.5x+78.2=287

-78.2 -78.2

move the constant to the right side and change it's sign

0.5x=287-78.2

--> 0.5x= 208.8

Subtract the numbers on the right hand side

0.5x= 208.8

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

0.5x 0.5x

divide both side of the equation by 0.5

answer ---> x= 417.6

8) Given: Graham's monthly bank statement with deposits and withdrawals:

-25.20,−25.20,52.75,-22.04,−22.04,-8.50,$94.11

If Graham's balance in the account was $47.86 at the beginning of the month .

Then the account balance at the end of the month =

=47.86+(-25.20+ 52.75- 22.04- 8.50+ 94.11)

=47.86+(52.75 + 94.11 − 25.20− 22.04− 8.50)

=47.86+(146.86− 55.74)

47.86+(91.12)=47.86+91.12= 138.98

Thus, the account balance at the end of the month= $138.98

Hey there!

[tex]|\displaystyle\frac{x-1}{2} |=7[/tex]

Let's say that x-1 is negative:

[tex]\displaystyle\frac{-x+1}{2} =7[/tex]

The first step is to multiply both sides by 2:

[tex]\text{-x+1=14}[/tex]

Now, move 1 to the right, using the opposite operation:

[tex]\text{-x=14-1}[/tex]

[tex]\text{-x=13}[/tex]

Divide both sides by -1:

[tex]\text{x=-13}[/tex]

I hope you find my answer helpful.

Good luck!

Step-by-step explanation:

1.  circle every 3 mustard seeds, 5 chili power and 1 salt

2. So draw two circles and five squares to represent 1 batch of chocolate milk and to represent 2 do the same thing (make sure to circle the two separate batches)

Answer:

The radius of the circle is about 5

Step-by-step explanation:

The formula for the radius of the circle with a area is:

- R= the square root of the area divide by pi ( π)

or - R= the square root of A/ π

Plug in 78.5 into the formula

then you get the radius which is 5.

Answer:

Adjacent

Step-by-step explanation:because it is right next to 4

The correct term that can be used to classify angles 3 and 4 is: A) adjacent.

If two angles lie next to each other and they share one side and a vertex, then, both angles can be called adjacent angles.

An example of such angles that share a common side and a vertex are angles 3 and 4 as shown in the image.

Therefore, the correct term that can be used to classify angles 3 and 4 is: A) adjacent.

Answer:  2

Step-by-step explanation:

The circumference of a circle is 2*radius*pi.

We can set up an equation as we know the circumference as 4pi.

4pi = 2*radius*pi

Divide both sides by pi:

4 = 2*radius

Divide both sides by 2:

radius = 2

Answer:

2 ft

Step-by-step explanation:

The equation for circumference is:

[tex]C=2\pi r[/tex]

We can plug in the given value for circumference to solve for the radius.

[tex]4\pi=2\pi r[/tex]

Divide both sides by 2π

Answer:

Step-by-step explanation:

3 angles in a triangle always add up to be 180.
So, angle prq = 180 - 49 - 80 = 51

Angle qrx is supplementary to prq => angle qrx = 180 - 51 = 129

No. They are not equivalent because sure, we can multiply them by 5,000 to get these 2 numbers, but 7 is not divisible by 5,000

Therefore, they are not equivalent ratios.
