1 answer:

3 0

Easy peasy

sub random points for x and solve for y
or solve for y and sum points for x and get y values

some easy points that work most of the time
sup
x=0
y=0

if x=0
0-4y=-18
4y=18
y=9/2
y=4.5
(0,4.5) is one point

if y=0
x-4(0)=-18
x=-18
(-18,0) is aonther

another is
(-5,2)

3 points are
(0,4.5)
(-18,0)
(-5,2)

How do I work out 60% of 25?

ira [324]

Answer:

Step-by-step explanation:

Multiply: 25x.60=15

The reason why you multiply 25 times .60 is because you need to change the percentage to a decimal. The way you change you from a percentage to a decimal is by moving the decimal twice to the left.

So, 60%=.60

Solve each equation.SHOW work plz

$3 \frac{1}{2} r = 28 \\ \frac{7}{2} r = 28 \\ \frac{ \frac{7}{2} }{ \frac{7}{2} } r = \frac{28}{ \frac{7}{2} } \\ r = \frac{ \frac{56}{2} }{ \frac{7}{2} } \\ r= \frac{56}{7}$

$1 \frac{1}{2} c =6 \\ \frac{3}{2} c= \frac{12}{2} \\ \frac{ \frac{3}{2} }{ \frac{3}{2} } c= \frac{ \frac{12}{2} }{ \frac{3}{2} } \\ c= \frac{ \frac{12}{2} }{ \frac{3}{2} } = \frac{12}{3} =4 \\ c=4$
