Charles bought a box of fruit that contained only oranges and tangerines.
There were 5 oranges for every 3 tangerines in the box,
there were 20 oranges in the box.
Which of the following proportions can be used to find x, the number of tangerines in the box?

x=12

S1tep-by-step explanation:

oranges=20                                                              

20/5=4

tangerines=x

x=4x3

x=12

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
