Answer:
we have 10 red marbles and 15 white marbles
Step-by-step explanation:
<u>Step 1:</u> Given data
Total marbles = 25
Ratio red: white = 2:3
<u>Step 2:</u> Write an equation
Red marbles = X
White marbles = Y
X+ Y = 25
X = 2/3 Y
2/3 Y + Y = 25
5/3 Y = 25
Y = 15
X =2/3 * 15 = 10
To control this we can plug this in the equation X + Y = 25
10 + 15 = 25
10/15 = 2/3
This means we have 10 red marbles and 15 white marbles
The diagram tells you it is 33°, so the answer is B
Answer:
the answer is b
Step-by-step explanation:
The addition of a negative is basically the same as subtraction.
Since your adding -35 to 90, your just taking away 35 from 90.
You would set up the problem like this:
90 + – 35
Or you could write it out like this:
90 – 35
Either way, 90 + – 35 = 55
The answer would be B, 1.7 and 1.8.
HOPE THIS HELPS! ^_^
