Solve the system of equations algebraically.

andrew11 [14]

Answer: d. (17, 20)

Step-by-step explanation:

We have the following system of equations:

$x-3y=8$ (1)

$5x-4y=5$ (2)

Isolating $x$ from (1):

$x=\frac{8+3y}{4}$ (3)

Substituting (3) in (2):

$5(\frac{8+3y}{4})-4y=5$ (4)

Isolating $y$ :

$\frac{40}{4}+\frac{15 y}{4}-4y=5$ (5)

$10-5=4y-\frac{15 y}{4}$ (6)

$y=20$ (7)

Substituting (7) in (1):

$x-3(20)=8$ (8)

Isolating $x$ :

$x=17$ (9)

Hence, the correct option is d. (17, 20)

Which statement is true about polynomial 5s^6t^2 + 6st^9 - 8s^6t^2 - 6t^7 after it has been fully simplified?

Marina86 [1]

Answer: 3t²(2st⁷ - s⁶ - 2t⁵)

Step-by-step explanation:

5s⁶t² + 6st⁹ - 8s⁶t² - 6t⁷ 5s⁶t² and - 8s⁶t² are like terms which = -3s⁶t² when combined

= 6st⁹ - 3s⁶t² - 6t⁷ next, factor out the GCF of 3t²

= 3t²(2st⁷ - s⁶ - 2t⁵)

Subtract 1.05 from a certain number. Multiply the difference by 0.8, add 2.84 to the product then divide the sum by 0.01 and get

attashe74 [19]

Just do the whole process backwards
700*0.01=7
7-2.84=4.16
4.16/0.8=5.2
5.2+1.05=6.25
