Answer:

angle <B = 76

Step-by-step explanation:

The measure of an exterior angle is equal to sum of two interior angles that is not adjacent to the exterior angle.

We can write the following equation with this information to find the value of angle <B

<B + 71 = 147 subtract 71 from both sides

<B = 76

Mara simplifies the expression: -(7x - 3y) + 2(x + 4). Her work is shown. In what step does she make a mistake?

likoan [24]

Correct steps are shown

Correct simplified expression is:

$-(7x - 3y) + 2(x+4) = -5x + 3y+8$

Solution:

Given that: Mara simplifies the expression

$-(7x - 3y) + 2(x+4)$

Correct steps are:

From given,

$-(7x - 3y) + 2(x+4)$

Use the distributive property,

a(b + c) = ab + bc

Therefore,

$-(7x - 3y) + 2(x+4) = -7x +3y + 2x + 8$

Group the like terms

$-(7x - 3y) + 2(x+4) = -7x + 2x + 3y + 8\\\\Combine\ the\ like\ terms\\\\-(7x - 3y) + 2(x+4) = -5x + 3y+8$

Thus the expression is simplified

Answer:

Step-by-step explanation:

Angle on a straight line = 180

106 + ∠st = 180

∠st = 180 - 106 = 74

x = ∠st + 23

= 74 + 23

= 97

Pls answer 31 and 32. Show all your work.

Veronika [31]

31. diameter is twice radius. volume cylinder = πr²h
112π = π(7)²h
112π/(49π) = h
16/7 = h
32. volume of sphere is (4/3)πr³
if r = 1 the volume just = (4/3)π

both answers are C
