Solve the equation: 5(r + 4) = -12 + 7r*

Mathematics
1 answer:
sveticcg [70]3 years ago
5 0

Answer:

r=16

Step-by-step explanation:

5(r + 4) = -12 + 7r

<u>➠ Use the distributive property to multiply 5 by r +4:</u>

5r+20=-12+7r

<u>➠ Subtract 7r from both sides:</u>

5r+20-7r=-12

<u>➠ Combin 5r and -7r to get -2r:</u>

-2r+20=-12

<u>➠ Subtract 20 from both sides:</u>

-2r=-32

<u>➠ Divide both sides by -2:</u>

r=\frac{-32}{-2}

r=16

Find the real numbers x and y that make the equation true (x+6i)=(3-i)+(4-2yi)​
Ronch [10]

Answer:

x = 7

y = -7/2

Step-by-step explanation:

(x+6i)=(3-i)+(4-2yi)​

First look at the real parts

x = 3 +4

x = 7

Then look at the imaginary part

6i= -i -2yi

6 = -1-2y

Add 1 to each side

6+1 = -2y

7 = -2y

Divide by -2

7/-2 = y

The algebraic form of a sequence is 4n+1. write the sequence​
diamong [38]

Answer:

5, 9, 13, 17, 21, .....

Step-by-step explanation:

To generate the sequence, substitute n = 1, 2, 3, 4, ..... into the rule

a₁ = 4(1) + 1 = 4 + 1 = 5

a₂ = 4(2) + 1 = 8 + 1 = 9

a₃ = 4(3) + 1 = 12 + 1 = 13

a₄ = 4(4) + 1 = 16 + 1 = 17

a₅ = 4(5) + 1 = 20 + 1 = 21
