18 : 3 = 6 : 1

Solution:

Try to reduce the ratio further with the greatest common factor (GCF).

The GCF of 18 and 3 is 3

Divide both terms by the GCF, 3:

18 ÷ 3 = 6

3 ÷ 3 = 1

The ratio 18 : 3 can be reduced to lowest terms by dividing both terms by the GCF = 3 :

18 : 3 = 6 : 1

Therefore:

18 : 3 = 6 : 1

All you do is you divide so in this case you can divide 3 by both 18 and 3 so 18 divided by 3 gives you 6 and 3 divided by 3 gives you 1 so the answer would be 6:1

What are the possible values of x if (4c-5)^2= 49?

kykrilka [37]

Answer:

c = 3 c = -1/2

Step-by-step explanation:

(4c-5)^2= 49

Take the square root of each side

sqrt((4c-5)^2)= ±qrt(49)

4c-5 = ±7

Separate into two equations

4c-5 = 7 4c-5 = -7

Add 5 to each side

4c-5+5 = 7+5 4c-5+5 =-7+5

4c =12 4c = -2

Divide by 4

4c/4 = 12/4 4c/4 = -2/4

c = 3 c = -1/2

How do i solve 51/2x-7=62

Nataly [62]

51/2x-7=62

Multiply both sides by 2x-7

$\frac{51}{2x-7}$ ×(2x-7) = 62(2x-7)

2. Switch sides

62(2x-7) = 51

3. Divide each side by 62

$\frac{62(2x-7)}{62}$ = $\frac{51}{62}$

4. Simplify

2x-7 = 51/62

5. Add 7 on both sides

2x-7+7 = (51/62)+7

6. Simplify

2x = 485/62

7. Divide both sides by 2

2x/2= 485/62/2

x= 485/124

(2/3)^x-1=27/8, Find x. Please, a step-by-step explanation.

Vaselesa [24]

Answer:

x=-2

Step-by-step explanation:

(2/3)^x-1=27/8

Rewriting the right hand side

(2/3)^x-1=(3/2)^3

We know that a^-b = 1/a^b Hint: { 1/(3/2) = 2/3}

(2/3)^x-1=(2/3) ^-3

The bases are the same, so the exponents are the same

x-1 = -3

x -1+1 = -3+1

x = -2

Solve the unknown angle measure?<br><br>Help Any1 ASAP! Will Mark Brainliest!

zlopas [31]

Answer:

X=40°

X=30°

X=50°

Step-by-step explanation:

Let our unknown angles be denoted by $X$

Part I

We are given the sum of the angles as 70°, the known as 30° and the unknown as X;

To find X, we subtract the known angle from the sum as:

X=70°-30°=40°

Hence X= 40°

Part II

We are given the sum of the angles as 70°, the known as 40° and the unknown as X;

To find X, we subtract the known angle from the sum as:

X=70°-40°=30°

Hence X= 30°

Part III

We are given the sum of the angles as 80°, the known as 30° and the unknown as X;

To find X, we subtract the known angle from the sum as:

X=80°-30°=50°

Hence X= 50°
