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

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!

Have a great day!

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:

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

6. C. 4x-7

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

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:

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.

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

[tex]\frac{4\pi}{2\pi}=r\\r=2\ ft[/tex]

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]

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

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.

Answer:

x = 20; angles = 58°

Step-by-step explanation:

Since the given triangle is an isosceles triangle & the 2 opposite angles are equal, then even the opposite angles of the equal opposite sides will be equal.

So,

3x - 2 = x + 38

3x - x = 38 + 2

2x = 40

x = 40/2

x = 20

Angles:

■ 3x - 2

= 3(20) - 2

= 60 - 2

= 58°

■ x + 338

= 20 + 38

= 58°

=》Both the angles are equal & each measure 58°
