1.shirts were on sale at 3 for $35.59. estimate the cost of one shirt? 2. estimate to decide if you can buy 4.8 pounds of hamburger at $2.99 per pound for $12.00

Number 1:
So, to find the unit price/rate, you do y divided by x. Y is the dependent variable and x is the independent. The number of shirts you buy tells you what the price will be. So, the cost/number of shirts=unit price.
35.59÷3
11.86333≈11.86
So, the cost of one shirt is $11.86.

Number 2:
Let's see. We need to round the bounds and the price per pound. 4.8 is closer to 5 than 4, so let's round it up to 5. 2.99 is closer to 3 than 2, so round it up to 3. We need to multiply it.
5×3=15
15>12
So, you can not purchase the hamburger with $12.

Tell me if this helps!!

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.
