this is because the bottom line has to equal 180, the angles given, 50 and 60, add up to 110, meaning the missing angle is 70 hope this helps :)

Answer:

30

Step-by-step explanation:

Add all the measures 50+35+85+65+60= 210

subtract 180 from 210 and you get

210-180 = 30

we use 180 because  Example: Angles on one side of a straight line always add to 180 degrees. 30° + 150° = 180° When a line is split into 2 and we know one angle, we can always find the other one.

What is the solution to 8x - 3(2x - 4) = 3(x - 6)?
A.30
B.2
C.6
D.No solution

Answers

Answer: A.30

Step-by-step explanation:

Let's solve your equation step-by-step.

8x−3(2x−4)=3(x−6)

Step 1: Simplify both sides of the equation.

8x−3(2x−4)=3(x−6)

8x+(−3)(2x)+(−3)(−4)=(3)(x)+(3)(−6)(Distribute)

8x+−6x+12=3x+−18

(8x+−6x)+(12)=3x−18(Combine Like Terms)

2x+12=3x−18

2x+12=3x−18

Step 2: Subtract 3x from both sides.

2x+12−3x=3x−18−3x

−x+12=−18

Step 3: Subtract 12 from both sides.

−x+12−12=−18−12

−x=−30

Step 4: Divide both sides by -1.

−x/-1 = -30/-1

x=30

Brad has a garden with dimensions 12 feet long x 7 feet wide. He wants to enlarge the garden to an area of 119 square feet. How much farther will he need to extend the length of the garden to attain his desired

Answers

Answer:

the length will need to be increased by 5 feet

He will need to 5 feet extend the length of the garden to attain his desired.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Brad has a garden with dimensions 12 feet long x 7 feet wide.

And, He wants to enlarge the garden to an area of 119 square feet.

Now,

Let the number of additional feet added to the length = x

So, We can formulate;

⇒ 7 (12 + x) = 119

⇒ 84 + 7x = 119

⇒ 7x = 119 - 84

⇒ 7x = 35

⇒ x = 5

Thus, He will need to 5 feet extend the length of the garden to attain his desired.

Step-by-step explanation:

A die has 6 faces with numbers 1, 2, 3, 4, 5, 6.

The faces that are less than 3 are 1, 2.

2 faces have numbers less than 2.

The desired outcome can happen 2 ways, 1 or 2.

The total number of possible outcomes is 6: 1, 2, 3, 4, 5, or 6.

p(event) = (number of desired outcomes)/(total number of possible outcomes)

p(less than 3) = 2/6 = 1/3

The probability of rolling a number less than 3 is 1/3.

Now we find 1/3 of 420.

1/3 * 420 = 420/3 = 140

Answer:

Step-by-step explanation:

-2x+4=6x-12  Add 2x to both sides.

+2x    +2x

4=8x-12         Add 12 to both sides.

+12  +12

/8 /8

2=x

Hope this helps you out and have a great day (～^▽^)～

Answer:

x=2

Step-by-step explanation:

-2x + 4 = 6x - 12

First add 2x to each side: 4=6x−12+2x

Now simplify 6x-12+2x: 4=8x-12

add 12 to both sides: 4+12=8x

Simplify 4+12: 16=8x

Divide both sides by 8: 16/8

you end up with x=2
