7. What is the length of XY

A 2
C 120
B 90
D 10

Answer:

20x-21y+14

Step-by-step explanation:

1/5(100x-105y+70)

20x-21y+14

sub 2 for any "x"

3(2)^2-2(2)+1

6^2-4+1            i dont know if you need to simplify even more but if you do

36-4+1         32+1     31

i hope this helps you!

Answer:

The answer is 9.

Step-by-step explanation:

Hey there, so it looks to me that you just have to subsitute 2 in for x, and solve the equation. Like this.

1. Plug in X: 3(2)^2 -2(2) + 1

2. Solve exponents (2)^2 = 4, so the equation is 3(4) - 2(2) + 1

3. Multiplication: 3 × 4 = 12, and -2 × 2 = -4, so the equation is 12 - 4 + 1

4. Addition: -4 + 1 = -3, so it is now 12-3

5. Subtraction: 12-3 = 9, so the answer is 9!

I hope this helps.

Answer:

Step-by-step explanation:

Step-by-step explanation:

The equation is given as;

−4(x−3)=20

Gwendolyn's flaw is in the following lines;

−4x + 12 = 20

−4x = 32

When collecting like terms, the moment 12 crosses over, it becomes - 12 and not + 12

The correct solution is given as follows;

Step 1: Expand the brackets

This results to;

- 4x - (-4 * 3) = 20

-4x + 12 = 20

Step 2: Collect like terms

This results to;

- 4x = 20 - 12

- 4x = 8

Step 3: Solve for x

x = 8 / (-4)

x = -2

Answer:

A. 38°

Step-by-step explanation:

angle of tangents of circle = (Bigger arc - smaller arc) / 2

x = (218 - 142) / 2 = 76 /2 = 38°

minimum is: (8,5)

Answer:

515.5 mph

Step-by-step explanation:

I am fairly confident we are taking the same test/quiz thing right now and I figured this one out so here ya go:

60 degrees + 11 sec = 60.183 degrees

3960 * cos(60.183) = 1969       some number in relation to the distance to the poles

2 * pi * 1969 = 12371.8

12371.8 / 24 = 515.5mph

look up "How to Calculate Rotational Speed Around Earths Axis" on YT, video is by " VAM! Physics & Engineering" that is where I found the formula stuffs

Answer:

2x² - 7x - 15

Step-by-step explanation:

Given

(2x + 3)(x - 5)

Each term in the second factor is multiplied by each term in the first factor, that is

2x(x - 5) + 3(x - 5) ← distribute parenthesis

= 2x² - 10x + 3x - 15 ← collect like terms

= 2x² - 7x - 15

Answer:

24%

Step-by-step explanation:

150 = 54 + 72 = 126 + 24 = 150

24/100 = 24%

Ahhh...first we need to find out the percentage of the oranges+the apples. then take it away from 100%.

I did a bit of tinkering and figured out that the orange percentage is 36% of it.

([tex]\frac{150}{54} =\frac{75}{27} =36%[/tex]%)

That means that the apples are 48% and the pears are 100-(36+48)=100-84=16%

Answer:

6

Step-by-step explanation:

3/4*8=6

The requried number of Ruth filled with soda is 6 cups.

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

Here,

To find the number of cups Ruth filled with soda, we need to divide the amount of soda she poured into cups by the amount of soda in each cup.

Ruth poured 1/8 liter of soda into cups. To convert this to cups, we need to know that 1 liter is equal to 4 cups. So, 1/8 liter is equal to:

(1/8) x 4 cups = 0.5 cups

Ruth has 3/4 liters of soda in her refrigerator, which is equal to:

(3/4) x 4 cups = 3 cups

So, the number of cups Ruth filled with soda is:

= 3 / 0.5
= 6 cups

Thus, the requried number of Ruth filled with soda is 6 cups.

Answer:

x = 180

∠DBC = 23

∠ABC = 157

Step-by-step explanation:

A straight line is always 180 degrees

A to D line = 180

6x + 19 + x = 180

7x + 19 = 180

      -19     -19

7x = 161

/ 7     / 7

161 /7 = 23

x = 23

Then plug it in

6x + 19

6 ( 23 ) + 19 = 157

x

x = 23
