X = 25
X + 20 = 45
3x = 75

Answer 2

Answer:

h=V/lw

Step-by-step explanation:

1. Since your trying to get h by itself, divide both sides by lw.

2. You will know have lwh divided by lw and V divided by lw.

3. you cross out the lw next to the h because the division cancels it.

4. Now you have h=V/lw.

The first part you would add the -1/16 with -11/16 to get an answer of -12/16. Fill in the first blank from the left to be 11 so it is 11/16. The other blank in that row should be a 1 like it is in the original equation.
Second row blank would become 12 because 11+1 =12. The third row of blanks would then simplify 12/16 to be 3/4 because both 12 and 16 can be divided by 4 to make 3 and 4 respectively.
-3/4 + -1/4 equals -1 because -4/4 simplifies to -1.

In the diagram, which two angles must be supplementary with angle 6?

4 lines intersect to form 16 angles. The angles created, clockwise from top left are 1, 2, 3, 4; 5, 6, 7, 8; 13, 14, 15, 16; 9, 10, 11, 12.
Angle 5 and Angle 7
Angle 1 and Angle 10
Angle 14 and Angle 16
Angle 7 and Angle 11

Answers

i believe it’s 5 and 7

The two angles must be supplementary with angles 6 will be angle 5 and 7.

What is mean by Angle?

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

⇒ 4 lines intersect to form 16 angles.

And, The angles created, clockwise from top left are 1, 2, 3, 4; 5, 6, 7, 8; 13, 14, 15, 16,

Here, two combinations of angles 5 and 7 are having a sum of 180 degrees with angle 6.

So, The supplementary angles to angle 6 are angle 5 and angle 7.

Thus, The two angles must be supplementary with angles 6 will be angle 5 and 7.

If granola costs $2.20 per pound, how much does 0.8 pound of granola cost?

$1.40
$1.76
$2.28
$2.75

Answers

Answer:

$1.76

Step-by-step explanation:

when you multiply 2.20x 0.8 you get 1.76. at first I thought division was needed, but the answer to 2.20/0.8 is 2.75- which is more than the original cost. (sorry if this is confusing but) 0.8 pound is less than 1 pound, so the answer would need to be less than 2.20.

The correct answer is 1.76
