Answer:

Step-by-step explanation:

let x be the number of one- bedroom and y the number of two - bedroom apartments , then create 2 equations and solve simultaneously.

x + y = 12 ( subtract y from both sides )

x = 12 - y → (1)

360x + 450y = 4950 → (2)

substitute x = 12 - y into (2)

360(12 - y) + 450y = 4950 ← distribute parenthesis and simplify left side

4320 - 360y + 450y = 4950

4320 + 90y = 4950 ( subtract 4320 from both sides )

90y = 630 ( divide both sides by 90 )

y = 7

there are 7 two- bedroom apartments

Marco is making three tiles pictures. he uses 310 green tiles to make each picture. he uses 50 fewer red tiles than green tiles

Anettt [7]

Hi there!

To solve this problem, we need to first find the amount of red tiles he used by subtracting 50 from 310, and then finding the sum of the two numbers.

310 - 50 = 260

Now, we know that there are 260 red tiles.

3 * 310 = 930
3 * 260 = 780

930 + 780 = 1710

So, the answer is 1710 tiles total.

Hope this helps!

Solve 2 log x = log 64. (1 point)

Vladimir79 [104]

Answer:

Step-by-step explanation:

2log(x)=log(64)

By logarithms properties

$xlog_{a}(b)=log_{a}(b^{x} ) \\$

log(x²)=log(64)

When you have log or ln in both sites, you delete them and...

x²=64

$\sqrt[]{x^{2} } =\sqrt{64} \\x=8$

Korvikt [17]

<span>cylindrical vase
r=radius </span>cylinder=radius cone
h= height cylinder=height cone
Volume cylindrical vase (V1)= 63 cm³=pi*r² *h

cone
Volume cone (V2)=pi*r² *h
if radius cylinder=radius cone and height cylinder=height cone
then V1=V2
therefore
V2= 63 cm³

the answer is The volume of cone is 63 cm³
