Answer:
Divide the number of miles (1080) by the number of gallons (15).
1080 miles / 15 gallons = 72 miles per gallons
72 miles per gallons is the unit rate
Step-by-step explanation:
Why did u spread that so much
1/4-3/7*7/8 = 1/4 - 3/8 = 2/8 - 3/8 = -1/8
Out of 6, the chance for a 1 or a 5 is 2. Probability is the something is the number of desired outcomes over the number of all possible outcomes. Therefore the probability is 2/6 to roll a 1 or a 5. From here, we need to find how much 2/6 of 100 is.
2/6 = x/100
200/6 = x
33.3 = x
Since its impossible to roll part of a dice, we'll round to a whole number. 33.3 rounds to 33, therefore he will roll a 1 or a 5 33 times.
Yes, on the left side you are adding 3x+2 in one and 2+3x in the other. these add to the same number because addition is Commutative on the real numbers.
Answer:
x = -1
, y = 5
Step-by-step explanation:
Solve the following system:
{5 x + 3 y = 10 | (equation 1)
x = y - 6 | (equation 2)
Express the system in standard form:
{5 x + 3 y = 10 | (equation 1)
x - y = -6 | (equation 2)
Subtract 1/5 × (equation 1) from equation 2:
{5 x + 3 y = 10 | (equation 1)
0 x - (8 y)/5 = -8 | (equation 2)
Multiply equation 2 by -5/8:
{5 x + 3 y = 10 | (equation 1)
0 x+y = 5 | (equation 2)
Subtract 3 × (equation 2) from equation 1:
{5 x+0 y = -5 | (equation 1)
0 x+y = 5 | (equation 2)
Divide equation 1 by 5:
{x+0 y = -1 | (equation 1)
0 x+y = 5 | (equation 2)
Collect results:
Answer: {x = -1
, y = 5
