Solve 4(r+1.9)-9r=12.2 r= type integer or decimal rounded to the nearest hundredth as needed

zimovet [89]

4(r+1.9)-9r=12.2
4r + 7.6 -9r = 12.2
-5r = 12.2 - 7.6
-5r = 4.6
r = 4.6/-5
r = - 0.92

Solve the equation -x/6greaterthanequalto3

enot [183]

Answer (depending if the fraction is positive or negative):

x ≥ 18
x ≤ -18

Step-by-step explanation:

If the fraction is positive:

Write it out: $\frac{x}{6} \geq 3$
Multiply each side by 6 to cancel out the 6 under x. It should now look like this: x ≥ 18

If the fraction is negative:

Write it out: $-\frac{x}{6} \geq 3$
Multiply each side by -6 to cancel out the -6 under x. It should now look like this: x ≤ -18

I hope this helps!

This i forgot and i need help fast can someone please help.. I will give brainliest

GalinKa [24]

Answer:

1.) 471.24

2.) 1231.5

3.) 113.1

Step-by-step explanation: A = pi x r^2 + pi x r x ^2

1.) a = 3.14 x (5)^2 + 3.14 x 5 x ^2

a = 3.14 x 25 + 3.14 x 5 x 25

a = 78.54 + 392.70

a ≈ 471.24

2.) A = 3.14 (7)^2 + 3.14 x (7) x ^2

a = 3.14 x 49 + 3.14 x 7 x 49

a = 153.93 + 1077.57

a ≈ 1231.5

3.) a = 3.14 (3)^2 + 3.14 x 3 x ^2

a = 3.14 x 9 + 3.14 x 3 x 9

a = 28.27 + 84.82

a ≈ 113.1

Lisa completed the table to describe the product of a mystery one - digit factor and factor and each numbers

deff fn [24]

Answer: part A is 0, 2, 4, 6, 8 and part B is Because the products all are even, the mystery factor must also be an even number. We have selected all of the even one-digit numbers.

Step-by-step explanation:

So, the number you need to find is between 0 and 9, because is a 1-digit number. For example, it cannot be 10 because 10 is a 2-digit number.

So, the number could be like 0,1,2,3...etc

In the table, the "X" in the left upper corner is the symbol for multiplication.

The "?" in the left lower corner represents the mystery number.

The table shows that the product of the mystery number and 1,2,3,4 and 5 is always an even number

For example, the product of the mystery number and 3 is even.

That means that our mystery must be even.

So, we know that the mystery number is between 0 and 9 and it must be even.

Therefore, the mystery number can be one of the following numbers:

0, 2, 4, 6, 8
