I got 8/10 or 80% because if you add up all sandwichs together, you get 50, then you add up ham and tuna sandwichs and get 40 so 40/50 would be 80/100 to make it a percent or fraction.. hopefully this makes sense and i helped:) i wish i could just send the work to you so it could make more sense lol

Lines m and n are graphed on the coordinate plane below select all of the statements that are true
Bezzdna [24]

Answer:

the answers are: b, c, and e

Step-by-step explanation:

since line m is pointing down, the slope is negative

since line n is pointing up, the slope is positive

since line m's y intercept is 2, and line n's intercept is -3, and 2 is greater than -3, the y intercept for line m is greater than that of line n

Solve the equation (linear equation)<br><br> <img src="https://tex.z-dn.net/?f=8%5E%7B2x%2B7%7D%20%3D%20%28%5Cfrac%7B1%7D%7B32%7
Minchanka [31]

Answer: x=-1

Step-by-step explanation:

By the negative exponent rule, you have that:

(\frac{1}{a})^n=a^{-n}

By the exponents properties, you know that:

(m^n)^l=m^{(nl)}

Therefore, you can rewrite the left side of the equation has following:

(\frac{1}{8})^{-(2x+7)}=(\frac{1}{32})^{3x}

 Descompose 32 and 8 into its prime factors:

32=2*2*2*2*2=2^5\\8=2*2*2=2^3

Rewrite:

(\frac{1}{2^3})^{-(2x+7)}=(\frac{1}{2^5})^{3x}

Then:

(\frac{1}{2})^{-3(2x+7)}=(\frac{1}{2})^{5(3x)}

As the base are equal, then:

-3(2x+7)=5(3x)

Solve for x:

-6x-21=15x\\-21=15x+6x\\-21=21x\\x=-1

Solve mathematics question, please:) Unanswered re-asked question.
Fiesta28 [93]
Remember you can do anything to an equation as long as you do it to both sides

and when multiply by negative, flip sign

8+h>2+3h
minus h both sides
8+h-h>2+3h-h
8+0>2+2h
8>2+2h
minus 2 both sides
8-2>2-2+2h
6>0+2h
6>2h
divide by 2 both sides
6/2>2h/2
3>1h
3>h
