Answer:

A. m∠ 2= 41°

B. m∠4 =61°

Step-by-step explanation:

Compliment means that the two angles will add up to 90°, and Supplement means to add up to 180°.

A. m∠1 + m∠2 = 90°

49°+ m∠2 = 90°

m∠2 = 90° - 49°

m∠2 = 41°

-----------------------------------------------------------------------------

B. m∠3 + m∠4 = 180°

119 + m∠4 = 180°

m∠4 = 180° - 119°

m∠4 = 61°

------------------------------------------------------------------------------

I hope you understand the topic now.

→ (7xy - 2xy) + (5yz + 4yz) + (-3zx + 9zx - 3xz) + (5x) + (-4y)

→ 5xy + 9yz + 3zx + 5x - 4y

Hence, option (a) is the correct answer.

What is the solution to 2(x - 3) = 2x + 5
laila [671]

Answer:

X cannot be decided

Step-by-step explanation:

According to the question,we will start solving the problem by dealing with the bracket first

So let's get to work

2(x-3)=2x+5

Bracket first

2x-6=2x+5

So let's collect like terms

2x-2x=5+6

0=11

Which means the that we can't get the value for x because x has already been eliminated

So to my own understanding there is no definite solution to get the real value of x

I hope you understand

kirill [66]

Answer:

Last week the owner spend <u>$42.32</u> on waffle cones.

Step-by-step explanation:

Given:

An ice cream shop owner pays $0.12 per regular cone and $0.23 per waffle cone. Customers are allowed to choose which type of ice cream cone they would prefer.

If two thirds of the 276 vibes sold last week were waffle cone.

Now, to find the amount the owner spend on waffle cones last week.

Last week waffle cone sold were = \frac{2}{3}\ of\ 276.

=\frac{2}{3} \times 276\\\\=\frac{552}{3} \\\\=184.

<u><em>Last week number of waffle cones sold were = 184.</em></u>

<u><em>Price of per waffle cone = $0.23.</em></u>

Now, to get the owner spend on waffle cones last week we multiply last week number of waffle cones sold were by price of per waffle cone:

184\times 0.23\\\\=\$42.32.

Therefore, last week the owner spend $42.32 on waffle cones.
