PLS HELP I REALLY NEED HELP PLS!

Mathematics
1 answer:
Softa [21]3 years ago
8 0

Answer:

1 1/5 or 12/10

Step-by-step explanation:

310+910=?

The two fractions have like denominators so you can add the numerators.

Then:

3+910=1210

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 12 and 10 using

GCF(12,10) = 2

12÷210÷2=65

The fraction

65

is the same as

6÷5

Convert to a mixed number using

long division for 6 ÷ 5 = 1R1, so

65=115

Therefore:

310+910=1 1/5

Hope this Helps!

Brenda and her best friend went on a vacation together. They both paid for a flight, and Brenda had a fancy room for $150 per ni
Mila [183]

Answer:

A. 2x + 150y = 1,500

   2x + 120y = 1,320

The flights were $300 each, and they stayed 6 nights.

B. $1,380

Step-by-step explanation:

Let x be the cost of the flight (in one side) and y be the number of nights on their vacation.

A. Brenda had a fancy room for $150 per night, then she paid $150y for y nights.  Brenda's total is $1,500, then

150y+2x=1,500

Brenda's friend had a smaller room for $120 per night, then she paid $120y for y nights.  Brenda's friend total is $1,320, then

120y+2x=1,320

Subtract two equations:

150y+2x-120y-2x=1,500-1,320\\ \\30y=180\\ \\y=6

Substitute into the first equation:

150\cdot 6+2x=1,500\\ \\900+2x=1,500\\ \\2x=600\\ \\x=300

Hence

2x + 150y = 1,500

2x + 120y = 1,320

The flights were $300 each, and they stayed 6 nights.

B. If a third friend joined them and stayed in a mid-range room for $130 per night, then he paid \$130\cdot 6=\$780

The total cost is

\$780+\$600=\$1,380

For the following right triangle, find the side length x.<br> 12<br> 16<br> х
makvit [3.9K]

Answer:

20

Step-by-step explanation:

which side is x ? the Hypotenuse - the side opposite of the 90 degree angle ? or is it one side touching the 90 degree angle ?

that is important. we need to know which side is the Hypotenuse to make the right calculations.

if I assume x is the Hypotenuse, then the calculation follows Pythagoras like this

x² = 12² + 16² = 144 + 256 = 400

x = sqrt(400) = 20

but just in case, if x is a side touching the 90 degrees angle, then the would look like this (depending on which of the other sides is the Hypotenuse)

either

12² = 16² + x²

144 = 256 + x²

-112 = x²

that did not work. a square root of a negative number did not work for actual distances.

or

16² = 12² + x²

256 = 144 + x²

112 = x²

x = sqrt(112) = 10.58
