9.25 − 4.5q = -19.37 − 15.1q

Mathematics

Natalija [7]3 years ago
5 0

Step 1: Simplify both sides of the equation.

9.25−4.5q=−19.37−15.1q

9.25+−4.5q=−19.37+−15.1q

−4.5q+9.25=−15.1q−19.37

Step 2: Add 15.1q to both sides.

−4.5q+9.25+15.1q=−15.1q−19.37+15.1q

10.6q+9.25=−19.37

Step 3: Subtract 9.25 from both sides.

10.6q+9.25−9.25=−19.37−9.25

10.6q=−28.62

Step 4: Divide both sides by 10.6.

\frac{10.6q}{10.6} =  \frac{-28.62}{10.6}

q=−2.7

The irrational numbers are: √8, √10 and √15

Step-by-step explanation:

A rational number is a number that can be written in the form p/q where p&q are integers and q≠0.

"All the numbers whose square root is not a whole number and has an infinite number of digits after decimal, are irrational numbers"

So in the given options

\sqrt{4} = 2

Which can be written in the required form so √4 is a rational number

\sqrt{8}=2.828427124746190097603.....

√8 has an infinite expansion hence it cannot be written in the p/q form, so it is an irrational number

\sqrt{10}=3.16227766016837933....

√10 has an infinite expansion hence it cannot be written in the p/q form, so it is an irrational number

\sqrt{15}=3.87298334620.....

√15 has an infinite expansion hence it cannot be written in the p/q form, so it is an irrational number

\sqrt{36} = 6

Which can be written in the required form so √36 is a rational number

Hence,

The irrational numbers are: √8, √10 and √15

Arnold's entire workout consisted of 10 minutes of warm up exercise, 25 minutes of lifting weights, and 15 minutes on the treadm
lord [1]

Add all the times together:

10 + 25 + 15 = 50 minutes total.

For the ratio divide the time for weights by total time:

25/50 which reduces to 1/2

The ratio is 1/2

Hello,

I suppose equations are:

x+y=3 (1)
x+2y=9 (2)

(2)-(1)==>y=6
(1)==>x=3-6

x=-3, y=6
Sol={(-3,6)}

Move the -7p over to the right....by adding
-7 = 10p +23
Move the 23 over to the left by subtracting
-30 = 10p
divide by 10
p = -3
