Answer:

Solving for x. Want to solve for y instead?

1 Factor out the common term 44.

4(7x+8y)=884(7x+8y)=88

2 Divide both sides by 44.

7x+8y=\frac{88}{4}7x+8y=

3 Simplify \frac{88}{4}

to 2222.

7x+8y=227x+8y=22

Solve for x. (have to add extra letters so the question works)

zloy xaker [14]

Answer:

x=11°

Step-by-step explanation:

-Sum of angles of a triangle should alway be 180 degrees

35+110+2+3x=180

-Add all known values

147+3x=180

-Subtract 147 from both sides

3x=33

-Isolate x by divind both sides by 3

x=11°

When is a polynomial factored completely?

Jet001 [13]

Answer:

A polynomial is factored completely when nothing else in the expression can be factored

Example:

x^2+3x-4 completely factored looks like (x+4)(x-1)

If F(x)=3x-2/6 which of the following is the inverse of F(x)?

lana66690 [7]

Answer:

Step-by-step explanation:

I'm seeing that f(x) is

$\frac{3x-2}{6}$

What you do to find an inverse is switch the x and y coordinates and then solve for the new y. Switching the x and y gives us:

$x=\frac{3y-2}{6}$

Now we have to solve for the new y. Begin by muliplying both sides by 6 to get:

6x = 3y - 2 and

6x + 2 = 3y so

2x + 2/3 = y

To put it back into function notation:

$f^{-1}(x)=2x+\frac{2}{3}$

Find the value of x and y

Romashka [77]

Step-by-step explanation:

$\triangle ABC \sim\triangle DEF..(Given) \\ \therefore \frac{AB}{DE} =\frac{BC}{EF}=\frac{AC}{DF}..(CSST)\\\\\therefore \frac{6}{4} =\frac{7}{x}=\frac{8}{y}\\\\ \therefore \frac{6}{4} =\frac{7}{x} \\ \therefore \: x = \frac{7 \times 4}{6} \\ \\\therefore \: x = \frac{28}{6} = \frac{14}{3} \\ \\ \huge \red{ \boxed{ \therefore \: x = \frac{14}{3} }} \\ \\ \because \: \frac{6}{4} =\frac{8}{y} \\ \\ \therefore \:y = \frac{4 \times 8}{6} \\ \\ \therefore \:y = \frac{32}{6} \\ \\ \huge \purple{ \boxed{ \therefore \:y = \frac{16}{3} }}\\ \\$

PLEASE HELP

nata0808 [166]

Answer: the first option is the correct answer.

Step-by-step explanation:

Martin runs 3/4 mile three days a week. We would assume that he runs a total of 3/4 miles in three days of each week.

In four weeks the number of days that he runs would be

3 × 4 = 12 days

Since he runs 3/4 miles in 3 days, the number of miles that he would run in 12 days would be

3/4 × 12 = 9 miles

He would run 9 miles in four weeks
