Answer:

The x-coordinate of the solution to this system of equations is $2$

Step-by-step explanation:

we have

$3x-y=2$ ------> equation A

$x+y=6$ ------> equation B

Adds equation A and equation B

$3x-y=2\\x+y=6\\--------\\ 3x+x=2+6\\4x=8\\x=2$

3x − y = 2

y = 3x - 2

x + y = 6

x + 3x - 2 = 6

4x - 2 = 6

4x = 6 + 2

4x = 8

x = $\frac{8}{4}$

x = 2

Hence, the x co-ordinate is 2.

Answer:

C. $72\pi$

Step-by-step explanation:

The radius of the circle is 24 units, then the area of the whole circle is

$\pi r^2=\pi \cdot 24^2=576\pi \ un^2.$

The shaded circle is limited by 45° angle, so its area is

$\dfrac{45}{360}=\dfrac{1}{8}$

of the area of the whole circle.

The area of the shaded circle is

$\dfrac{1}{8}\cdot 576\pi =72\pi \ un^2.$

Gianna put $1000 in a savings account for 18 months, The interest on the account is 3.5%. How much will Gianna earn in interest?

zimovet [89]

Answer:

amount of interest = 52.5

amount at the end of the period = 1052.5

Step-by-step explanation:

use the formula for simple interest

PRT/100

P is the principle

R is the rate of interest charged

T is the Time taken

18 months = 1 years 6 months ( 1.5 years)

1000 * 3.5 * 1.5 = 5250

5250/100 = 52.5

the amount of interest = 52.5

the amount she will have at the end of the period

= 1000 +52.5

= 1052.5
