<h3>Answer: A) 20+10h</h3>

Work Shown:

It grows 2h inches for 4 weeks, so 2h*4 = 2*4h = 8h is the amount it grows for those 4 weeks.

Then it grows h inches per week, for 2 more weeks, giving h+h = 2h additional inches.

Overall, 8h+2h = 10h is the amount the plant grows.

It starts off at 20 inches so its final height is 20+10h

Order these from least to greatest 3 39/40 , 3 19/20 , 3 1/2

Lera25 [3.4K]

Hey!

First change all the fractions so that they have a common denominator: 40

$3 \frac{39}{40} = 3 \frac{39}{40}$

$3 \frac{19 \times 2}{20 \times 2} = 3 \frac{38}{40}$

$3 \frac{1 \times 20}{2 \times 20} = 3 \frac{20}{40}$

Now order them:

$3 \frac{39}{40} , 3 \frac{19}{20} , 3 \frac{1}{2}$

Good luck and hope this helps! :)

What is the solution to the system of equations? y = A system of equations. Y equals StartFraction 2 over 3 EndFraction x plus 3

Sauron [17]

Answer:

The solution to the given system of equations is (-2, $\frac{5}{3}$ )

Therefore the values of x and y are x=-2 and $y=\frac{5}{3}$

Step-by-step explanation:

Given equations can be written as

$y=\frac{2}{3}x+3\hfill (1)$

$x=-2x+3x=-2\hfill (2)$

Solving equation(2) we get

x=-2

Substitute x=-2 in equation (1) we get

$y=\frac{2}{3}(-2)+3$

$=-\frac{4}{3}+3$

$=\frac{-4+9}{3}$

$=\frac{5}{3}$

Therefore the values of x and y are x=-2 and $y=\frac{5}{3}$

The solution to the given system of equations is (-2, $\frac{5}{3}$ )

An icecream shop charges $3.39 for a dish of ice cream. A costomer can also order toppings for $0.59 each. If x represents the n

Leya [2.2K]

Answer:

3.39 + 0.59x

Step-by-step explanation:

Cost of a dish of ice cream = $3.39

Cost of toppings = $0.59 each

x = number of toppings

which expression can be used to determine the total charge in dollars, for a dish of ice cream with x toppings

Total charge for a dish of ice cream with x toppings = 3.39 + 0.59x

The expression is 3.39 + 0.59x

PLEASE HELP... VERY URGENT... WILL GIVE BRAINLIEST!!!

lakkis [162]

Answer:

Step-by-step explanation:

a) Pythagorean theorem,

altitude² + base² = hypotenuse²

h² + (w² - 1)² = (w² + 1)²

h² = (w² + 1)² - (w² - 1)²

{Compare with (a + b)² - (a -b)² = 4ab where a =w² & b = 1}

h² = 4*w²*1

h² = 4w²

$h=\sqrt{4w^{2}} = \sqrt{2*2*w*w} \\\\\\h = 2w$

b) Area of triangle = $\frac{1}{2}b*h$

$=\dfrac{1}{2}*(w^{2}-1) *2w\\\\= (w^{2}-1)*w = w^{2}*w - 1*w\\\\=w^{3}-w$

c) w =2

Area of triangle = 3w = 3*2 = 6
