Robert drew a parallelogram with 2 55 degree angles. What are the measures of the 2 other angles? Both of the angles have to be the same number

Answers

Answer 1

Answer: Angles in a parallelogram have to equal 360.

Let x represent the measurement of the unknown angle.

2(55) + 2x = 360
110 + 2x = 360
2x = 250
x = 125

125 degrees

1) 3x-2=x+10

Now, lets solve this step-by-step.

3x - 2 = x + 10
-x -x

3x - x = 2x 2x - 2 = 10

2x - 2 = 10
2x - 2+2 = 10+2 The inverse operation helps isolate the variable.

2x = 12

2x/2 = 12/2

x = 12/2
x = 6

Answer: x = 6

2) x + 4 = 19 - 2x

We can solve this much faster

x + 4 = 19 - 2x
+2x

x+2x = 3x

3x + 4 = 19
-4 -4

19-4 = 15

3x= 15
3x/3 = 15/3
x= 5

Answer: x = 5

3) 8x - 20 = x + 15

Much faster now!!

8x - 20 = x + 15
-x
8x-x = 7x

7x - 20 = 15
+20 +20
15+20 = 35

7x = 35
7x/7 = 35/7
x = 35/7
x = 5

Answer: x= 5

let x be the unknown number of all 3 equations
1.) 3x - 2 = x + 10 x=6
2.) x + 4 = 19 - 2x x=5
3.) 8x - 20 = x + 15 x=5

The perimeter of a rectangular garden is 338
feet. If the length of the garden is
96
feet, what is its width?

Answers

Since the length is 96 ft., there are two sides of that length, so 96x2=192. Now subtract that from 338. 338-192=146. Divide that by two, since there are still two sides left. 146/2=73. The width is 73 ft.

The price of jeans was reduced $6 per week for 7 weeks. By how much did the price of the jeans change over the 7 weeks?

If 120% of a is equal to 80% of b, then what is the value of a b in terms of b

Answers

If you would like to know what is the value of a b in terms of b, you can calculate this using the following steps:

120% of a = 80% of b
120/100 * a = 80/100 * b /*100
120 * a = 80 * b /120
a = 80 / 120 * b
a = 2/3 * b

The correct result would be a = 2/3 * b.

120% = x 1.2

80% = x 0.8

$1.2a=0.8b \n \n a= (0.8)/(1.2)b \n \n \boxed{a= (2)/(3)b }$
