Please help if you can <3
Bogdan [553]

Answer:

1) x = 71

2) x = 117

5)

m<1: 35

m<2: 77

m<3: 52

m<4: 77

m<5: 65

m<6: 25

Step-by-step explanation:

1)

x + 41 + 68 = 180

x + 109 = 180

x = 71

2)

x + 47 + 16 = 180

x + 63 = 180

x = 117

3)

<2 + 103 = 180

<2 = 77

<1 + 68 + 77 = 180

<1 + 145 = 180

<1 = 35

<4 + 103 = 180

<4 = 77

<5 + 41 + 77 = 180

<5 + 115 = 180

<5 = 65

<6 + 65 = 90

<6 = 25

<3 + 103 + 25 = 180

<3 + 128 = 180

<3 = 52

What is the solution set?
ki77a [65]
Answer:

1). Simplifying
Y = -5x + 45

Reorder the terms:
Y = 45 + -5x

Solving
Y = 45 + -5x

Solving for variable 'Y'.

Move all terms containing Y to the left, all other terms to the right.

Simplifying
Y = 45 + -5x

(hope this kind of helps) :D

How to turn a fraction to a decimal
Rudiy27


To turn a fraction into a decimal, divide the numerator by the denominator. For example, to turn 5/10 into a decimal, divide 5 with 10 and you will get 0.5. So, the decimal for 5/10 is 0.5.

Hope it helps:)

A spherical balloon is inflated with a gas at the rate of 500 cm3/min. How fast is the radius of the balloon increasing at the i
Burka [1]

The volume of the sphere is expressed in the formula V = 4/3 pi r^3. The rate of change of volume is determined by differentiating the formula: dV/dt = 4pi r^2 dr/dt. When we substitute 500 cm3/min as dV/dt and 30 cm as r. Then dr/dt is equal to 0.0442 cm/min
