Rosie weighed 7 pounds (lb.) 11 ounces (oz) when she was born. Linda weighed 8 lb. 10 oz when she was born. What is the total weight of these girls when they were born?

Answer:

-5

Step-by-step explanation:

Answer:

- 5

Step-by-step explanation:

A rational number has the form

[tex]\frac{a}{b}[/tex] ← where a and b are integers

Given

- [tex]\frac{20}{4}[/tex] ( divide numerator/ denominator by 4 )

= - [tex]\frac{5}{1}[/tex] ← a rational number

= - 5

Answer:

h=9.0991 ≈ 9.1

Step-by-step explanation:

V=π r²h

1400=3.14 (7)²h

1400=153.86 h

h=9.0991 ≈ 9.1

Answer:

Answer:

3/4

Step-by-step explanation:

you would get 6/8 but need to simplfiy to 3/4 since they both can divide by 2

Answer:

slope = [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 4, - 2) and (x₂, y₂ ) = (4, 4) ← 2 points on the line

m = [tex]\frac{4-(-2)}{4-(-4)}[/tex] = [tex]\frac{4+2}{4+4}[/tex] = [tex]\frac{6}{8}[/tex] = [tex]\frac{3}{4}[/tex]

Answer:

x = 60

m∠G = 114 degrees

Step-by-step explanation:

In the given figure

∵ EFGH is a parallelogram

∵ ∠E and ∠G are opposite angles

→ By using the rule above

∴ m∠E = m∠G

∵ m∠E = (2x - 6)°

∵ m∠G = (x + 54)°

→ Equate them

∴ 2x - 6 = x + 54

→ Subtract x from both sides

∵ 2x - x - 6 = x - x + 54

∴ x - 6 = 54

→ Add 6 to both sides

∵ x - 6 + 6 = 54 + 6

∴ x = 60

→ Substitute the value of x in the expression of ∠G to find it

∵ m∠G = 60 + 54

∴ m∠G = 114 degrees

all of them are parrelel, they are all forming right angles

and im pretty sure the answer is number twooooooo for the next thing????? i hope this helped!

Answer:

56x + 34

Step-by-step explanation:

12(3 + 5x) + 1/4(16x - 8)

First, use the distributive property. You will get:

(12)(3) + (12)(5x) + (1/4)(16x) - (1/4)(8)

Next, multiply the numbers. You will then have:

36 + 60x + 4x - 2

Now, rearrange the numbers. The variables go in the front. This is what it should look like:

60x + 4x + 36 - 2

Add 60x and 4x, then subtract 36 and 2. This is your answer:

56x + 34

Step-by-step explanation:

25 x 100% / 5%

Answer:

(3,7)

Step-by-step explanation:

x-3y=-2 -----equation i

x+3y=16-----equation ii

Subtract the two equations from each other

-6y=-18

-6y/-6=-18/-6

y=3

Substitute for x in equation i

x-3(3)=-2

x-9=-2

x=-2+9

x=7

x=7,y=3

Answer:

X is 7, and Y is 3.

Step-by-step explanation:

Step 1: Add 3y to both sides

x - 3y + 3y = -2 + 3y

x = 3y - 2

Step 2: Substitute 3y - 2 for x in x + 3y = 16

x + 3y = 16

3y - 2 + 3y = 16

Step 3: Simplify both sides of equation

6y - 2 = 16

Step 4: Add 2 to both sides

6y - 2 + 2 = 16 + 2

6y = 18

Step 5: Divide both sides by 6

6y/6 = 18/6

y = 3

Step 6: Substitute 3 for y in x - 3y = -2

x - 3(3) = -2

Step 7: Multiply 3 by 3 for 9

x - 9 = 2

Step 8: Switch sides!

x = 9 - 2

Step 9: Subtract 9 minus 2 to get 7

x = 7

With that we have our final answers: x = 7, and y = 3.

Answer:

n=-6

Step-by-step explanation:

2(n+5)=-2

distribute

2(n+5)

2xn 2x5

2n+10

2n+10=-2

subtract 10 from both sides

10-10=0

-2-10=-12

2n=-12

divide each side by 2

2n/2=n

-12/2=-6

n=-6

Answer:

Only Integers are considered even or odd. So this is not possible to solve. But if you HAD to choose, I believe that it will be even because you round up then its 8 and there you have a even number

Answer:

c=13

Step-by-step explanation:

Answer:

x=13

Step-by-step explanation:

divide both sides by 5

then move the constant to the right and change signs

2x=18+8

add numbers

divide both sides by 2

Answer:

y+2x=7 (1)

x=3+y (2)

Replace x = 3+y (2) into (1) => y+2(3+y) = 7

=> y = 1/3 and x = 3+1/3 =10/3

Step-by-step explanation:

Answer:

YES its 8

Step-by-step explanation:

Answer:

Let's define the variables:

x = yards of Organza ribbon that you buy.

y = yards of Satin ribbon that you buy.

We know that the price per yard of Organza ribbon is $0.07, this means tat if you buy x yards, the cost will be:

C = x*$0.07

And the cost of the Satin ribbon is $0.04, so if you buy y yards of that ribbon, the cost will be:

C = y*$0.04

Adding that together, the total cost is:

C = x*$0.07 + y*$0.04

Now we know that you pay $5, this means that the total cost is exactly $5, then we have the equation:

$5 = x*$0.07 + y*$0.04

Now we can isolate the variable y to get:

y = ($5/$0.04) - x*($0.07/$0.04)

y = 125 - x*1.75

Now we can just input different values of x to find the correspondent value of y.

This means that:

if x = 0 (0 yards of the Organza ribbon)

then:

y = 125 - 0*1.75 = 0

This combination is:

0 yards of organza, and 125 yards of satin.

Now, if x = 20, then:

y = 125 - 20*1.75  = 90

This combination is:

20 yards of organza, and 90 yards of satin.

if x = 40, then:

y = 125 - 40*1.75 = 55

This combination is:

40 yards of organza, and 55 yards of satin.

The 3 combinations that we found cost exactly $5.

Answer:

slope = [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1,3) and (x₂, y₂ ) = (4, 4) ← 2 points on the line

m = [tex]\frac{4-3}{4-1}[/tex] = [tex]\frac{1}{3}[/tex]

Answer:

no 5/3 is larger

Step-by-step explanation:

Answer:

no

Step-by-step explanation:

5/3 is a improper fraction, therefore it is bigger.
