3x+7-6=(8/7)-0 Value of x?

ArbitrLikvidat [17]

Answer:

$\boxed{\sf x = \dfrac{1}{21}}$

Explanation:

$\rightarrow \sf 3x+7-6= \dfrac{8}{7} - 0$

simplify the following

$\rightarrow \sf 3x+1= \dfrac{8}{7}$

subtract 1 from both sides

$\rightarrow \sf 3x+ 1 -1= \dfrac{8}{7} - 1$

simplify the following

$\rightarrow \sf 3x= \dfrac{1}{7}$

multiply both sides by 1/3

$\rightarrow \sf 3x \cdot \dfrac{1}{3}= \dfrac{1}{7}\cdot \dfrac{1}{3}$

simplify the following

$\rightarrow \sf x = \dfrac{1}{21}$

Name an equivalent ratio for 1/2 with a denominator of 20

Westkost [7]

To begin with, equivalent fractions represent the same part of a whole number. So I need to find a fraction, with a denominator of 20, that is the same value as 1/2:
1/2 = ?/20
1*10/2*10 = 10/20

Since the denominator needed to be 20, I multiplied the numerator and the denominator (1/2) by 10 to get 10/20. So, 1/2 and 10/20 are equivalent.

An automatic doughnut machine can produce 1500 doughnuts in 9 hours.

Svetllana [295]

Answer:

1 hr, 48 minutes

Step-by-step explanation:

you can create a proportion:

doughnuts/hours = doughnut/hours (h)

1500/9 = 300/h

cross-multiply to get:

1500h = 2700

h = 27/15

h = 1 12/15, which is 1 hr, 48 minutes because 12/15 = 48/60
