Solve 5x - 8y = 11 for y.

disa [49]

Answer:

y = $\frac{5x-11}{8}$

Step-by-step explanation:

Given

5x - 8y = 11 ( subtract 5x from both sides )

- 8y = 11 - 5x ( multiply through by - 1 )

8y = - 11 + 5x = 5x - 11 ( divide both sides by 8 )

y = $\frac{5x-11}{8}$

Solve whether the equation have 1 solution no solution or infinity solution

babymother [125]

Steps to solving equations:
Simplify/combine the like terms
Isolate the variable (Get the variable on one side
Solve for the variable

-2y - 7 + 5y = 13 - 2y Simplify/Combine terms
3y -7 = 13 - 2y Isolate variable by adding 2y to both sides
5y - 7 = 13 Add 7 to both sides to get y alone on one side
5y = 20 Divide by 5 on both sides to solve for y
y = 4
You can check your answer by replacing y with 4 in the original equation.

In the 30-60-90 triangle below, side s has a length of

mario62 [17]

Answer:

4, 4√3

Step-by-step explanation:

In a 30-60-90 triangle:

The leg opposite of the 30-degree angle is 1/2 of the hypotenuse: 8/2 = 4

The longer leg is √3 times the shorter leg: 4*√3 = 4√3

Check work: 4^2+(4√3)^2 = 8^2 --> 16+48 = 64 --> 64 = 64

Math help what is the answer will give brainliest.

artcher [175]

The two equations are
$x + y = 7$
and
$4x + 2.5y = 22$
the first equation can be solved for x to be
$x = 7 - y$
next you can substitute x in the second equation
$4(7 - y) + 2.5y = 22$
Distribute 4 to everything in the parentheses
$28 - 4y + 2.5y = 22$
combine like terms:
$28 - 1.5y = 22$
subtract 28 from both sides of the equation
$- 1.5y = - 6$
divide both sides by -1.5
$y = 4$
plug this in to the original equation of x+y=7
$x + 4 = 7$
subtract 4 from both sides.
$x = 3$
