Solve: y = 2x. y = -x+3. Write the coordinates (__, __)

romanna [79]

Answer:

(1,2)

Step-by-step explanation:

y = 2x. y = -x+3

Set the two equations equal

2x = -x+3

Add x to each side

2x+x = -x+x+3

3x = 3

Divide by 3

3x/3 = 3/3

x = 1

Now find y

y =2x = 2(1) = 2

Evelyn is making a candy that contains 25% dark chocolate and the rest milk chocolate. The candy has 3 pounds of milk chocolate.

Gnesinka [82]

A.
100%=all
so if 25% is dark and the rest is milk then
dark+milk=all
25%+milk=100%
minus 25% both sides
milk=75%

so
if milk chocolate=3lb then
3lb=75%
divide by 3
1lb=25%=dark chocolate
oops, I didn't use an equation
hmm

ratios and things
75%=milk
25%=dark

so we got
for m=pounds of milk chocolate
and d=dark chocolate
m/d=72/25 or m/d=3 and
m=3
duh
3/d=3
3=3d
1=d

B. 1 lb dark chocolate

soda is sold in aluminum cans that measure 6 inches in height and 2 inches in diameter. how many cubic inches of soda are contai

Gekata [30.6K]

Answer:

18.84 cubic inches

Step-by-step explanation:

Height of aluminum cans = 6 inches

Diameter of can = 2 inches

we know that diameter is twice of radius

So,

Diameter of can = 2 inches = 2* radius of can

radius of can = 2 inches/2 = 1 inches

We also know that volume of any cylindrical object is given by

volume of cylinder = $\pi r^2 h$

where h is height of cylinder

and r is radius of cylinder

___________________________________

Amount of soda in can will be equal to volume of can

$volume \ of \ can = \pi r^2h\\\\ volume \ of \ can = 3.14*1^2* 6 \ ( \pi= 3.14)volume \ of \ can = 18.84 \\\\$

Thus, 18.84 cubic inches of soda are contained in the given full can.
