Answer 1

Line BC is equal to line AD

∴

x + 17 = 3x + 7

x - 3x = 7 - 17

-2x = - 10

-2x / -2 = - 10 / -2

x = 5

AD

3x + 7

3(5) + 7

15 + 7

22

CD

2x - 6

2(5) - 6

10 - 6

4

BC

x + 17

5 + 17

22

AB

Line AB is equal to line CD therefore its length is 4

Answer:

x = 5

AB = 4

BC = 22

CD = 4

AD = 22

Answer:

[tex]x=\frac{12}{5}[/tex]

[tex]x=2.4[/tex]

Step-by-step explanation:

[tex]6x+2\left(2x-3\right)=18[/tex]

Expand 2(2x-3) by applying Distributive law:

[tex]2\times \:2x-2\times \:3[/tex]

Multiply:

[tex]2\times \:2x=4[/tex]

[tex]2\times \:3=6[/tex]

[tex]4x-6[/tex]

[tex]6x+4x-6=18[/tex]

Combine like terms:

[tex]6x+4x=10x[/tex]

[tex]10x-6=18[/tex]

Add 2 to both sides:

[tex]10x-6+6=18+6[/tex]

[tex]10x=24[/tex]

Divide both sides by 10:

[tex]\frac{10x}{10}=\frac{24}{10}[/tex]

[tex]x=\frac{12}{5}[/tex]

You are given that a = 6.54 (to 3 significant figures) and b = 123 (to 3 significant figures).
Calculate upper and lower bounds for each of the following, give your answers to 3 significant figures:
(a) a + b
(b) ab
(c) a/b
(d) b - 1/a

Answers

The upper and lower bounds for the numbers are illustrations of approximation

How to calculate the upper and lower bounds

The numbers are given as:

a = 6.54 (to 3 significant figures)

b = 123 (to 3 significant figures)

(a) a + b

We have:

a + b = 6.54 + 123

a + b = 129.54

When approximated, the bounds to three significant digits are:

Lower bound = 129

Upper bound = 130.1

(b) ab

We have:

ab = 6.54 * 123

a + b = 804.42

When approximated, the bounds to three significant digits are:

Lower bound = 804

Upper bound = 805

(c) a/b

We have:

a/b = 6.54/123

a/b = 0.0531707317

When approximated, the bounds to three significant digits are:

Lower bound = 0.0531

Upper bound = 0.0532

(d) b - 1/a

We have:

b - 1/a = 123 - 1/6.54

b - 1/a = 122.847094801

When approximated, the bounds to three significant digits are:

Lower bound = 122

Upper bound = 123

Is 2750 a reasonable answer for 917 * 33 explained

Answers

Answer:

No

Step-by-step explanation:

To make this simpler, we will round each number. 917 rounds to 900 and 33 rounds to 30. 900 * 30 = 27,000. We can do this in our head because 9 * 3 = 27, and there are three zeros total between 900 and 30, so we add three zeros after 27. 2750 is not a reasonable answer because the true answer is about 10 times greater than 2750.

The triangle is always 180 degrees
6x + 8x + 7 + 8x - 3 = 180
Simplify
22x + 4 = 180
Minus 4 from both sides
22x = 176
Divide 22 by both sides
X = 8
Can I get brainliest answer

Answer:

x = 8

Step-by-step explanation:

All angles of a triangle must add up to 180 degrees.

So 8x + 7 + 6x + 8x - 3 = 180

Combine like terms

22x + 4 = 180

Subtract 4

22x = 176

Divide

22x ÷ 22 = 176 ÷ 22 = x = 8

We can make sure this is correct by plugging in 8 for all x terms.

8(8) + 7 + 6(8) + 8(8) -3

64 + 7 + 48 + 64 - 3 = 180.

X = 8

Hope this helps.

[DUE TOMORROW] Answer using steps: A truck sprang a leak in its radiator, which held 480 ounces of fluid when it started to leak. Assuming the truck continues at 35 mph and it’s radiator leaks 4 ounces of fluid per minute, how many miles will the truck travel before the radiator is empty

Answers

Answer

It will make it 70 miles because it leaks 4 ounces every minute so divide 480 by 4 and get 120 with would be for how many minutes you would be able to drive with the leak. So convert minutes to hours and you get 2 hours and every hour you go 35 miles so multiply 35 by 2 and you get 70.
