Answer:

12

Step-by-step explanation:

Multiply both sides of the equation by 8/5.

4x-16=32

Move 16 to the other side

4x=32+16

add numbers on the right side

4x=48

divide both sides by 4

x=12

Answer:

0.0625 miles

Step-by-step explanation:

There is a faster way but this way makes more sense

1/4 miles = 440 yards

440/4 (since 4 people)

110 yards per person

Put back into miles

Everyone ran 0.0625 miles

Question

Daniel expanded the expression as shown. What errors did he make? Select three options.

[tex]-2(-8x-4y+3/4)=-10x-8y-1 \frac{1}{4}[/tex]

A. The first term should be positive.

B. The second term should be positive.

C. The last term should be -1 1/2, not -1 1/4.

D. He divided -8 by -2 instead of multiplying -8 by -2.

E. He did not simplify the expression completely.

Answer:

Daniel's errors are (a), (b) and (c)

Step-by-step explanation:

To do this, we only need to solve the expression on the left.

So, we have:

[tex]-2(-8x-4y+3/4)=[/tex]

Open bracket

[tex]-2(-8x-4y+3/4)=-2 * -8x -2 * -4y - 2 * 3/4[/tex]

[tex]-2(-8x-4y+3/4)=16x + 8y - \frac{2 * 3}{4}[/tex]

[tex]-2(-8x-4y+3/4)=16x + 8y - \frac{6}{4}[/tex]

[tex]-2(-8x-4y+3/4)=16x + 8y - 1\frac{1}{2}[/tex]

From the expression, we can see that:

So, Daniel's errors are (a), (b) and (c)

Answer:

6108795

Step-by-step explanation:

To obtain the number of ways the committee can be selected :

4 teachers from the 12 teachers available and 3 students from the 43 students available

Using combinatorics :

12C4 * 43C3

recall :

nCr = n! ÷ (n - r)!r!

Using calculator :

12C4 = 495

43C3 = 12341

12C4 * 43C3

495 * 12341

= 6108795

Answer:

Using Pythagoras theorem for right angled triangle,

x^2 = 14^2 + 15^2

X= ✓ 421

X=20.5

Answer:

∠1 = 66°

∠2 = 24°

∠3 = 24°

∠4 = 90°

Step-by-step explanation:

∠1 = 90 - 24 = 66°

∠2 = 24°

∠3 = 24° because segment DB bisects ∠ABC

∠4 = 90° because it is a right angle

Answer:

4

Step-by-step explanation:

The LCD (Least Common Denominator) of all the fractions is 4, so you only need to multiply by 4.

Hope this helps :)

Answer:

Step-by-step explanation:

The greatest denominator is 4 so all the fractions will be eliminated when all terms are multiplied by 4.

Answer:

Step-by-step explanation:

56(cos(33) + i sin(33)) = 7(cos(11°) + i sin(11°))

Divide both sides by 7 to get;

8(cos(33) + i sin(33)) = (cos(11°) + i sin(11°))

Expanding and Rearranging gives;

8cos(33) + 8i sin(33)) - cos(11) - isin(11)

This gives ;

8Cos(22) + 8i sin(22) = 8(Cos(22) + I sin(22)

Answer:

111°

Step-by-step explanation:

angles around a point = 360

360-138=222

angles at the centre is double the circumference

Step-by-step explanation:

Answer:

Step-by-step explanation:

Natasha use the distance formula

d = sq rt [ x2 - x1)^2 + (y2-y1)^2 ]

d = sq rt [ 2 - (-5) ) ^2  + (-3 - 4)^2 ]

d = sq rt [ 2 + 5 ) ^2 + -7^2 ]

d = sq rt [ 7^2 + - 7^2 ]

d = sq rt [ 49 +49]

d = sq rt { 98]

d = [tex]\sqrt{98}[/tex]

d = [tex]\sqrt{7*7*2}[/tex]

d = 7[tex]\sqrt{2}[/tex]

leave it in that from b/c the square root is in exact form  :)

Answer:

The answer is D

Step-by-step explanation:

We want to see which of the given values is a solution of the inequality:

x < 4

The correct option is A, x = 3.

So the inequality:

x < 4

This means that the variable must be a number smaller than 4.

Then we just need to select the option that is smaller than 4, the only option that meets this requirement is option A, x = 3

Also, as you can see in the number line, the only number that is in the shaded part is x = 3 (from the ones in the options).

Answer:

Step-by-step explanation:

I saw karma so i came as fast as I could- welp anyways

Lets test the first equation and coordinate #1 first, 3x-2y=12, and (10,9).

Here we can substitute x as 10 and y as 9, and solve the equation to see if 3(10)-2(9) equals 12 or not.

30-18=12, yep

now lets test the second coordinate, (0, -6). Substitute x as 0 and y as -6, and solve the equation.

3(0)-2(-6)=12

0+12=12, yep

So I definitely works

For II, lets do the same thing

(10, 9) -- 9=3/2*10-6

9=15-6, works

(0, -6) — -6= 3/2*0-6

-6=0-6, also works

So uh therefore I and II both work you see what I mean-

i apologize in advance if i made you more confused than you already are-

Step-by-step explanation:

The mean of a set of numbers, sometimes simply called the average , is the sum of the data divided by the total number of data. Example 1 : ... There are 8 numbers in the set. Add them all, and then divide by 8 . so just add all you numbers and divide it by 8. simple

Answer:

x = 13

∠WZX = 57°

Step-by-step explanation:

Because it is a rectangle, ∠XYZ is 90°

∠XZY + ∠YXZ = 90

(5x - 8) + (x + 20) = 90

simplify:

6x + 12 = 90

subtract 12 from each side

6x = 78

divide both sides by 6

x = 13

∠WZX is complimentary to angle (x + 20)

∠WZX = 90 - (13 + 20) = 57°

Answer:

choice 4) x = 27, ∠FDG = 62°, ∠GOF = 118°

Step-by-step explanation:

2x + 8 + 4x + 10 = 180°

6x + 18 = 180

6x = 162

x = 27

∠FDG = 2(27) + 8 = 62°

∠GOF = 4(27) + 10 = 118°

Answer:

Step-by-step explanation:

P=2K

50K+75P=1200, using P from above makes this equation become

50K+75(2K)=1200

50K+150K=1200

200K=1200

K=6, since P=2K

P=2(6)=12
