6th grade math , help me please :))

a)4.5:1

b)3.2:1

c)19.2:1

d)3.29:1

Step-by-step explanation:

A - (4.5 grams of salt per every one cup of water)

B - (3.2 ounce each week)

C - (19.2 grams to every 1 cubic centimeter)

D - ($3.29 per gallon of gas)

Divide the larger number by the smaller number to get the ratio.

If this helped, please rate, thanks, and mark brainliest :)

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.

thats not a system of equations, that is a solution
