Answer:

x= -3/2 y +6

Step-by-step explanation:

take 2x+3y = 12 and add 3y to both sides to get 2x= -3y + 12

then divide both sides by 2 to get x alone

x= -3/2y +6

Surface Area=7238in^2

We know

$\boxed{\sf Surface\:area=4\pi r^2}$

$\\ \sf\longmapsto 4\pi r^2=7238$

$\\ \sf\longmapsto 4\times \dfrac{22}{7}r^2=7238$

$\\ \sf\longmapsto r^2=\dfrac{7238\times 7}{88}$

$\\ \sf\longmapsto r^2=\dfrac{5066}{88}$

$\\ \sf\longmapsto r^2=575.75$

$\\ \sf\longmapsto r^2\approx576$

$\\ \sf\longmapsto r\approx\sqrt{576}$

$\\ \sf\longmapsto r\approx24in$

Tamara and Amir shared a candy bar. Tamara ate two fifths. Amir ate two fifths. How much is left?

marin [14]

Answer:

1/5

Step-by-step explanation:

Both Amir and Tamara ate 2/5 each.

2/5 + 2/5 = 4/5

If 4/5 of the candy bar was eaten, 1/5 of the candy bar remains because

5/5 - 4/5 = 1/5

(Remember that 5/5 just equals one whole, representing the whole candy bar)

4 glue sticks cost $7.76<br><br> Which equation would help determine the cost of 13 glue sticks?

Elza [17]

Answer:

$y=1.94x$

13 glue sticks cost $25.22.

Step-by-step explanation:

4 blue sticks cost $7.76, this means that one glue stick costs

$7.76/4 = $1.94.

Let $y$ be the cost of the glue sticks, and $x$ be the number of glue sticks; then

$\boxed{y=1.94x}$

We can use this equation to find the cost of 13 glue sticks; we just put $x=13\$ into our equation and it gives:

$y=1.94(13)=25.22$

So 13 glue sticks cost $25.22.
