What is the answer
7a-9b+6a-4b

Im having problems with this and need an answer with explanation if is positive maybe that way can be more easy to understand

Answers

Answer 1
13a-13b
This is because you have to add/subtract your like variables. So 7a + 6a=13a. Then you have -9b-4b=negative 13b. So 13a-13b

Answers

Answer:   39.25

========================================

Work Shown:

d = diameter = 10

r = radius = d/2 = 10/2 = 5

A = area of a full circle

A = pi*r^2 = 3.14*5^2 = 78.5

Cut this in half to get the area of a semicircle (aka half circle)

(78.5)/2 = 39.25

This result is approximate.

The question is in the picture.

Answers

Answer:

x = 7[tex]\sqrt{3}[/tex]

Triangle area formula: base * height * 1/2

We are given:

Base - 14 cm

Height - x

Using the pythagorean theroem (a^2 + b^2 = c^2) we can figure out the height.

We are given:

Side a - 14 / 2 = 7 cm

Side b - the height (x)

Side c - 14 (it's an equilateral triangle)

Now, substitute the given values:

7^2 + x^2 = 14^2

49 + x^2 = 196

x^2 = 147

x = [tex]\sqrt{147}[/tex]

x = 7[tex]\sqrt{3}[/tex]

K

measure of angle H =
measure of angle K = 137

Answers

Answer:

∠H = 137°

∠K = 76°

Step-by-step explanation:

The sum of the interior angles of a trapezoid = 360°

In a trapezoid, the angles on the same leg (called adjacent angles) are supplementary, meaning they add up to 180°

The legs are the non-parallel sides:  JK and HI

Therefore, 104 + ∠K = 180

⇒ ∠K = 180 - 104 = 76°

And, ∠H + 43 = 180

⇒ ∠H = 180 - 43 = 137°

Sum of two adjacent angles in trapezium equals 180°

[tex]\\ \tt\hookrightarrow <H+43=180[/tex]

[tex]\\ \tt\hookrightarrow <H=180-43[/tex]

[tex]\\ \tt\hookrightarrow <H=137[/tex]

And

HELP ME FIND MIDPOINT

Answers

Answer: (-1/2, 0) which is the same as saying (-0.5, 0)

================================================

Explanation:

The x coordinates of A and B are -2 and 1 respectively.

Add up those values to get -2+1 = -1

Then cut that result in half: -1/2 = -0.5

This is the x coordinate of the midpoint.

--------

Repeat for the y coordinates:

Add: 1 + (-1) = 0

Cut in half: 0/2 = 0

The y coordinate of the midpoint is 0

-------

Overall, the midpoint is located at (-1/2, 0) which is the same as writing (-0.5, 0). This is where the segment AB crosses the x axis.

If you only have a 1 3 cup measuring cup and a recipe calls for 5 1 3 cups of flour, how many 1/3 cups would you need to use?

Answers

Answer:

You would need 16 1/3 cups!

Step-by-step explanation:

I used an equation, but you could also use mental conversions! :

1/3c = 5 1/3

(1/3c)3 = (5 1/3)3 (multiply each side by 3 (3/1))

3c /3 = (48) /3 (divide each side by 3)

c = 16

:)

(c = cups!)

The requried number of 1/3 cups to make the recipe is 16.

What are equation models?

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

here,
Measuring cup = 1/3
Recipe required number of cups = 5 1/3 of flour,
Let the number of 1/3 cups = x
1/3x = 5 1 / 3
x/3 = 16 / 3
x = 16

Thus, the requried number of 1/3 cups to make the recipe is 16.

While shopping at the mall, Tom bought 3 hats and 4 pairs of glasses and spent $123. His friend Jerry bought the same type of items consisting of 1 hat and 3 pairs of glasses and spent $66. How much does a pair of glasses cost? How much does a hat cost?

Answers

Answer:

a pair of glasses costs $17

a hat costs $21

Step-by-step explanation:

h = hat

g = glasses

3h + 4g = 123

1h + 3g = 66

multiply the 2nd equation by 3

3h + 9g = 198

negate everything in the 1st equation and add it to the 'new' 2nd equation

    3h  + 9g = 198

+  -3h  - 4g = -123

5g = 75

g = 15

substitute the 15 in either one of the 1st equations

1h + 3(15) = 66

h + 45 = 66

h = 66-45

h = 21

to check, substitute both g=15 and h=21 into BOTH 2 original equations.
