Choose the equation below that represents the line passing through the point (2, -4) with a slope of 1/2.
A) y = 1/2 x + 5
B) y = 1/2 x - 3
C) y = 1/2 x - 5
D) y = 1/2 x + 3

we only need to put the values and find the equation

$y=(1)/(2)*x+5$

$-4=(1)/(2)*2+5$

$-4=6$

False

$y=\frac{}{}*x-3$

$y=(1)/(2)*x-3$

What percent of 90 is 50

Answers

The question is asking...

x% of 90 is 50

In math

"of" means multiply
"is" means equals

x% of 90 is 50 means

x% x 90 = 50
90x = 50
x = 50/90
x = .5555

Multiply by 100 to convert to percent (move decimal 2 places to the right)

.5555 = 55.55% = 55.6% rounded to the nearest tenth

% of 90 = 50
Lets keep n as the percentage
$(n)/(100)$ × 90 = 50
$(n)/(100)$ × $(90)/(90)$ = $(50)/(90)$
90 and 90 cancels out
$(n)/(100)$ = $(5)/(9)$
$(n)/(100)$ × 100 = $(5)/(9)$ × 100
100 and 100 cancels out
n = 55.55..% ≈ 55.6%

Kenny's weight is 6/7 times melvin's weight. what is the ratio of melvin's weight to the total weight of the two boys?

Answers

Answer:

$(7)/(13)$

Step-by-step explanation:

Let

x------> Melvin's weight

y------> Kenny's weight

we know that

$y=(6)/(7)x$

$x+y=x+(6)/(7)x=(13)/(7)x$ -----> total weight of the two boys

Find the ratio of Melvin's weight to the total weight of the two boys

$ratio=(x)/(((13)/(7)x)) =(7)/(13)$

Answer=7:13

Kenny's Weight*6/7=Melvin's Weight

So, for example, if Melvin's weigh was 7...

Kenny's Weight*6/7=7
divide both sides by 6/7
Kenny Weight=6

So we can say that Melvin's weight to Kenny's weight is 7:6

The boys total weights would be...
7+6=13

So Melvin's weight over the total weight of the two boys is:

7:13
