Answer:

1) A

2) I

3) G

4) B

Step-by-step explanation:

Bottom side: 7c - 1

Tall side: 6c + 2

P = 7c - 1 + 6c + 2 + 3c - 2 + 2c + 4c + 1 + 4c + 2

P = 26c + 2

P = 26(5) + 2

P = 132

P = 2(l + w)

P = 2(3d - 2 + 5d + 1)

P = 16d - 2

P = 16(3) - 2

P = 46

Marcia bought a bag of red white and blue balloons for the party there were 49 balloons in the bag if there are twice as many re

DedPeter [7]

Answer:

Red color= 28 balloon

Blue color= 14 balloon

White color= 7 balloon

Step-by-step explanation:

Given: There are 49 balloons

As given, there are 2 red balloon equal to the number of blue balloon

∴ $2 red= blue\ balloon$

Again given, there are 1/2 white balloon equal to the number of blue balloon.

∴ $\frac{1}{2} \ white= blue\ balloon$

As above equation, we can understand that:

$2\ red= \frac{1}{2} \ white\ balloon$

multiplying both side by 2

⇒ $4\ red= white\ balloon$

which mean, if we have 2 blue balloon then we will have 4 red and 1 white balloon.

∴ Total combination of all color of balloon= $2+4+1= 7$

Now, checking how many number of times combination can we have in 49 balloon.

$\frac{49}{7}= 7 \ times$

Next, finding number of balloon in each color.

Red color= $4\times 7= 28\ balloon$

Blues color= $2\times 7= 14\ balloon$

White color= $1\times 7= 7\ balloon$

What is the equation for <br><br> 6/7 - 1/8=

miv72 [106K]

Another way to put 6/7 - 1/8 is 48/56- 7/56 since the LCM of 7 and 8 is 56 (if you don’t know what that is I can explain it) sorta like subtraction you subtract both numerators (48 and 7 or 48-7) which gives you 41 then you put the denominator (56) below that. So in other words it equals 41/56

Answer:

y = x+1

Step-by-step explanation:

points (0,1) and (2,3)

slope =(y2-y1)/(x2-x1)

m = (3-1)/(2-0)

= (2/2)

m=1

the y intercept ( or where it crosses the y axis) is 1

y = mx+b

y = 1x+1

y = x+1
