Annie has $18.00 to spend at the grocery store. She is going to buy bags of nuts that cost $5.70 each and one box of cookies tha
Tcecarenko [31]

Answer: She can buy up to 2 bags of nuts

Step-by-step explanation:

Hi, to answer this question we have to write an inequality:

The product of the number of bags of nuts bought (n) and the price per bag (5.70); plus the price of one box of cookies (4.25) must be less or equal to Annie's money (18).

5.70n +4.25 ≤18

Solving for x:

5.70n ≤18 -4.25

5.70n ≤13.75

n ≤13.75/5.70

n ≤2.41  

n ≤2 (rounded)

She can buy up to 2 bags of nuts

I WILL MARK BRAINLIEST PLEASE HELP FIND ANGLE DEB <br><br> ITS DUE AT 12 PLEASE HELP PLEASE
Gemiola [76]

Answer:

\boxed {\boxed {\sf \angle DEB = 111 \textdegree}}

Step-by-step explanation:

We want to find angle DEB. We know AB is perpendicular to AC, CD is congruent to CE and angle B is 48 degrees.

ABC is a triangle. The angles in a triangle must add up to 180 degrees. Therefore:

  • ∠A+∠B+∠C= 180°

We know two angles: ∠B= 48° and ∠A= 90° (the little square denotes a right angle).

  • 90°+48°+ ∠C= 180°                               <em>Substitute values in.</em>
  • 138°+ ∠C =180°                                      <em>Add</em>  
  • 138°-138° ∠C= 180°-138°                       <em>Subtract 138 from both sides.</em>        
  • ∠C= 42°    

Note that angle C is part of another triangle. It is isosceles because the two legs (CD and CE) are congruent. Therefore, the two base angles (E and D) are congruent.

  • ∠C+∠D+∠E= 180°
  • ∠C+ 2∠D= 180°                             <em>Angles D and E are congruent</em>
  • 42°+ 2∠D= 180°                             <em>Substitute 42 in for angle C</em>
  • 42°-42° +2∠D= 180°-42°               <em>Subtract 42 from both sides.</em>
  • 2∠D=  138°
  • 2∠D/2= 138°/2                              <em>Divide both sides by 2.</em>
  • ∠D= 69°

∠D and ∠E equal 69 degrees.

Angle CED (∠E)  and DEB are on a straight line together. Therefore, they are supplementary and equal 180 degrees.

  • ∠CED+ ∠DEB= 180
  • 69° +∠DEB= 180°                    <em>Substitute 69 for angle CED</em>
  • 69°-69° +∠DEB= 180°-69°      <em>Subtract 69 from both sides</em>
  • ∠DEB=111°

Angle DEB is equal to <u>111 degrees</u>
