HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!
castortr0y [4]

Answer:

$3.75

Step-by-step explanation:

dimes= x

quarters= x+2

nickels= 2x+2

sum is 3.75

.10x+.25(x+2)+0.05(2x+2)=3.75

.10x+.25x+.50+0.10x+0.10=3.75

0.45x=3.15

x=7 dimes (0.70)

x+2=9 quarters (2.25)

2x+2=16 nickels (0.80)

They add to $3.75

Write an equation in slope-intercept form for the line passing through the pair of points.
Umnica [9.8K]
First find your slope! by doing
y2-y1/x2-x1
in this case it would be
2-(-3)/-1-(-6)
It would give you 5/5 which would reduce to 1 meaning your slope equals 1
with your slope now you should use the point slope formula y-y1=m(x-x1)

i’m going to use the point (-1,2) so the equation would be

y-2=1(x-(-1))

simplifying that you would get

y-2=1x+1

then put it in y=mx+b form and get

y=x+3

Please help me is this statement true or false 3(36 - 11) = 45?
viva [34]
Hi there! The answer is FALSE

To find the answer we need to work out the parenthesis.
3(36 - 11) =
3 \times 36 - 3 \times 11  =
108 - 33 =
75

75 does not equal 45 and therefore the statement is false.

PLSS HELP IF YOU TURLY KNOW THISS
yaroslaw [1]

Answer:

x = 11

Step-by-step explanation:

(0.3x - 2.1)/3 = 0.4

0.3x - 2.1 = 0.4 * 3

0.3x - 2.1 = 1.2

0.3x = 1.2 + 2.1

0.3x = 3.3

x = 3.3/0.3

x = 11
