Ebony earned scores of 72 70, 81, 99, and 88 on five math tests. Determine her

Minchanka [31]

Let it be x

$\boxed{\sf Average=\dfrac{Sum\:of\:terms}{No\:of\:terms}}$

$\\ \sf\longmapsto \dfrac{72+70+81+99+88+x}{6}=83$

$\\ \sf\longmapsto \dfrac{410+x}{6}=83$

$\\ \sf\longmapsto 410+x=498$

$\\ \sf\longmapsto x=498-410$

$\\ \sf\longmapsto x=88$

Write and solve an equation based off the verbal phrase: 6 more than x is equal to 33

kenny6666 [7]

Answer:

x + 6 = 33

Step-by-step explanation:

6 more than x means there's an increment in the value of x by addition of 6

x + 6 = 33

This leads to an algebraic linear equation. x is an unknown variable and can be solved for

we subtract 6 from both sides of the equation

x + 6 - 6 = 33 - 6

x = 27

Therefore, we can say 6 more than 27 is 33

Remer<br> 1) 5k? + 10k + 6 = 0

IceJOKER [234]

Ignoring the "?" in your question:

$5k+10k+6=0 \iff 15k+6=0 \iff k=-\dfrac{6}{15}$

If the "?" is a squared symbol that wasn't caught:

$5k^2+10k+6=0$

Use the quadratic formula

$x_{1,2}=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

to get the solutions:

$x_{1,2}=\dfrac{-10\pm\sqrt{100-120}}{10}$

as you can see, the discriminant is negative, so the equation has no solution.
