x + 25 + 4x + 10 = 180

5x + 35 = 180

5x = 145

x = 29

<1 = 29 + 25 = 54

<2= 4(29) + 10 = 116 + 10 = 126

Mandarinka [93]

x=2y-2

x=y+3

Substitute the second equation into the first

y+3=2y-2

solve for y

y=5

plug into original

x=y+3=5+3=8 or x=2(5)-2=8

Allentown got 8 ft of snow, Georgetown got 5 ft of snow.

Zoe used 3/8 of her ribbon to wrap a present. If she uses 9 feet of ribbon for the present how much ribbon did Zoe have it first

MArishka [77]

Let the total ribbon Zoe had was x feet.

Out of x feet, she used 3/8 part of it.

Hence, $\frac{3x}{8}$

3/8 part of the original ribbon is equal to 9 feet.

Hence, we get

$\frac{3x}{8} = 9$

=> Multiply 8 on both sides.

$3x=72$

Divide both sides by 3

$\frac{3x}{3}=\frac{72}{3}$

$x=24 ft$

Zoe had 24 feet of ribbon in starting... Answer

A right cylinder has the radius of 3.5cm and the height of 11cm if i place 3 ice cube with edge length of 2cm in the glass what

Brrunno [24]

Answer:

Volume of cylinder =

$\pi \times r {}^{2} \times h$

$\pi \times 3.5 {}^{2} \times 11 = 423cm {}^{3}$

Volume of 1 ice cube = 2*2*2= 8cm3

Volume of 3 ice cubes= 3*8= 24cm3

Volume of juice added = 423-24 = 399 cm3

Rudik [331]

Answer:

B) y - 5 = 2(x - 10)

Step-by-step explanation:

Slop = (5+7)/(10-4) = 12/6 = 2

Point slope form:

y - 5 = 2(x - 10)

or

y + 7 = 2(x - 4)
