Fred earns $6.50 an hour, plus tips, as a waiter. suppose he works 26 hours in a week. how much money must he receive in tips to earn at least $229 that week?

To solve this problem, we set up an equation for the problem statement. We let x as the number of hours Fred works and y as the tips he earned. The equation would be:

6.50x + y = 229

Since we are given the number of hours he worked which is 26 hours. Therefore, we can solve for the tip he should earn.

6.50(26) + y = 229
y = 60

Fred's total earning is the sum of its wage and the tips. Let x be the amount he must receive in tips. This value should be equal or greater than 229. The inequality that represents this is, 
                                           ($6.5)(26) + x ≥ 229
The value of x is 60. Therefore he must receive at least $60 as tips. 

Need the graph to answer this.

Answer: question no. 1 -a. yes, the sides are in the ratio 2 : 5.question no. 2 -b. 59°question no. 3 -c. angles x and y are remote interior angles.question no. 4 -d. 90°, 45° and 45°question no. 5 -b. mn and qrstep-by-step explanation: question no. 1 -rs : xu = 3 : 7.5 = 2 : 5rt : x? = 6.4 : 16 = 2 : 5st : u? = 6 : 15 = 2 : 5as the ratios of all sides are equivalent, the triangles must be congruent and the sides must be proportional.therefore, the answer is: a. yes, the sides are in the ratio 2 : 5.question no. 2 -in the second diagram, angle b is the only letter not shown. therefore, the number must be equivalent to angle b.if we substitute the value of angle b as being 22° in the first diagram, we can now use the angle sum of a triangle to obtain the value of angle a.angle sum of a triangle = 180°therefore: let angle a = aa + 99 + 22 = 180a = 180 - 99 - 22a = 59°therefore, the answer is: b. 59°question no. 3 -angles x and y don't share the vertex of the triangle with the exterior angle w. remote interior angles don't share a vertex of a triangle with an exterior angle. this means that angles x and y are remote interior angles.therefore, the answer is: c. angles x and y are remote interior angles.question no. 4 -the sum of all interior angles of a triangle must be equivalent to 180°.90°, 45° and 45° are the only set of angle measures that are equivalent to 180°.therefore, the answer is: d. 90°, 45° and 45°question no. 5 -the only pair of sides stated in the options which are corresponding are mn and qr.therefore, the answer is: b. mn and qr.
