Answer:
1:1 ratio
Step-by-step explanation:
a 1:1 ratio happens when the amount of the item is the same as the other. 1/4 cup of all purpose flour is the same amount as 1/4 rice flour so the recipe uses a 1:1 ratio
41+0.10x = 31+0.15x
10 +0.10x=0.15x
10=0.05x
x=10/.05
x= 200 text messages
check 200*0.10 = 20 +41 =61
200*0.15 = 30+31 = 61
they equal each other so number of texts is 200
46. Fortysix times 2 equals 92.
The answer is x= -3. 0.7(-3)-1.4=-3.5
I think it's 21/100 because I found the common denominator by multiplying by ten so I multiplied 1 times ten to get 10. Does that help?
