Mathematics
1 answer:
ololo11 [35]3 years ago
5 0

Answer:

x =  \frac{86}{5}   = 17 \frac{1}{5}  = 17.2

Step-by-step explanation:

( - 30 - 5x - 1) + 7 =  - 110

( - 31 - 5x) + 7 =  - 110

- 31 - 5x + 7 =  - 110

- 24 - 5x =  - 110

- 5x =  - 110 + 24

- 5x =  - 86

\boxed{\green{x =  \frac{86}{5}   = 17 \frac{1}{5}  = 17.2}}

Find the equation of a line that passes through the point (4,15) and is perpendicular to the equation below.
mr Goodwill [35]
The answer is D because to find the slope of a line that is perpendicular to another, you have to find the opposite reciprocal. so here the slope would be -1/4. now, take that slope and put it into an equation. like the following:
y =  \frac{ - 1}{4} x + b
now to find b you must insert the points into the equation (plug in 4 for x, and 15 for y).
15 =  \frac{ - 1}{4} (4) + b
b then equals 16. so, the answer is D.

Please help on this please thank you

30% = 0.3

Since 30% of 90 is 27, the average person uses approximately 27 gallons of water outdoors per day.

Solution:

To write percent to decimal, divide the number by 100.

$30\%=\frac{30}{100}

       $=\frac{30\div10}{100\div 10}

       $=\frac{3}{10}

       = 0.3

30% = 0.3

Average use of water each day = 90 gallons

30\%  \ \text{of} \ 90=0.3 \times 90

                = 27

Since 30% of 90 is 27, the average person uses approximately 27 gallons of water outdoors per day.

PLZ HELP WILL MARK BRAINLIEST!
mel-nik [20]

Answer:

So far we have looked at linear systems of equations in which the lines always intersected in one, unique point. ... When we graph them, they are one line, coincident, meaning they have all points in common. This means that there are an infinite number of solutions to the system.
