4x + 20 + 40 = 180
4x + 60 = 180
4x = 120
x = 30

Answer:

x = 30

Step-by-step explanation:

Angles on a line equal 180

4x + 20 + 40 = 180

4x + 60 = 180

Minus 60 on both sides.

4x = 120

Divide by 4 on both sides.

x = 30

A garden supply store sells two types of lawn mowers. The smaller mower costs $249.99 and the larger mower costs $329.99. 30 tot
lys-0071 [83]

Answer:

15( b+ a) - 2(a + 0 ) = c

then

c+b = t

We could put the two together to make 15(b+a)- 2(a+0) + b = t

Where t = 8379.70

a= £249.99  b= 329.99

Step-by-step explanation:

Equal amounts are 8549.7 from 30 mowers a+b = small and large.

If we use this as an even and take away a+b at different equations we can find the answer to be 8379.70 on the 2nd equation. First equation = 8579.70

8549.7- 249.99-249.99+329.99 to equal the given year to find c in first equation and total in year = t within the above equation.

Two cylindrical containers, C and D, with different capacities are shown below. What is the total volume of liquid held in these
Zielflug [23.3K]

Answer:

Option D. (x + 4)(x + 1)

Step-by-step explanation:

From the question given above, the following data were obtained:

C = (6x + 2) L

D = (3x² + 6x + 9) L

Also, we were told that half of container C is full and one third of container D is full. Thus the volume of liquid in each container can be obtained as follow:

Volume in C = ½C

Volume in C = ½(6x + 2)

Volume in C = (3x + 1) L

Volume in D = ⅓D

Volume in D = ⅓(3x² + 6x + 9)

Volume in D = (x² + 2x + 3) L

Finally, we shall determine the total volume of liquid in the two containers. This can be obtained as follow:

Volume in C = (3x + 1) L

Volume in D = (x² + 2x + 3) L

Total volume =?

Total volume = Volume in C + Volume in D

Total volume = (3x + 1) + (x² + 2x + 3)

= 3x + 1 + x² + 2x + 3

= x² + 5x + 4

Factorise

x² + 5x + 4

x² + x + 4x + 4

x(x + 1) + 4(x + 1)

(x + 4)(x + 1)

Thus, the total volume of liquid in the two containers is (x + 4)(x + 1) L.
