The number is 125 and the equation is 0.8x = 100

Step-by-step explanation:

80% of x is equal to 100.

Write an equation that shows the relationship of 80%, x, and 100

80% = 0.8

0.8x = 100

x = 100/0.8

x = 125

The number is 125 and the equation is 0.8x = 100

Your bag of rice says to mix 1 cup of rice with 2 cups of water. dela requ prov a. What is the ratio of rice to water? refer to

EastWind [94]

Answer:

(a) 1:2

(b) 6 cups

Step-by-step explanation:

(a) Given,

amount of rice mixture contains= 1 cup

amount of water mixture contains= 2 cups

$\textrm{So, the ratio of rice to water}\ =\ \dfrac{\textrm{amount of rice in mixturte}}{\textrm{amount of water in mixture}}$

$=\ \dfrac{1}{2}$

So, the ratio of rice to water is 1:2.

(b) Amount of rice in mixture = 3 cups

$\textrm{So, the ratio of rice to water}\ =\ \dfrac{\textrm{amount of rice in mixturte}}{\textrm{amount of water in mixture}}$

$=>\ \dfrac{1}{2}\ =\ \dfrac{3}{\textrm{amount of water in mixture}}$

=> amount of water in mixture = 3 x 2

= 6 cups

(c) $\textrm{amount of rice in mixture}\ =\dfrac{1}{3}$

$\textrm{So, the ratio of rice to water}\ =\ \dfrac{\textrm{amount of rice in mixturte}}{\textrm{amount of water in mixture}}$

$=>\ \dfrac{1}{2}\ =\ \dfrac{\dfrac{1}{3}}{\textrm{amount of water in mixture}}$

$=>\textrm{amount of water in mixture}\ =\ \dfrac{2}{3}$

So, the amount of water in the mixture will be $\dfrac{2}{3}$ cup.

What is the equation of the line whose slope is 3 that passes through the point (-1, 5).

sergey [27]

We knownthe equation of a line is y = mx + b. where m is slope and b is y intercept.

the point slope equation of a line is y - y1 = m (x - x1)

plug in x1 and y1 and m
y- (5) = (3)(x - (-1))
y - 5 = 3x + 3
y = 3x + 8
