We have to determine the number of blocks. We know that that number have 9 in the ones place. It also has the number in the hudreds place ( x ) which is 1 more than the number in the tens place ( y ). And: x + y = 11. Another equation is: x = y + 1. Therefore y + 1 + y = 11; 2 y = 11 - 1; 2 y = 10; y = 10 : 2; y = 5 and x = 5 + 1 = 6. Answer: There are 659 blocks<span>.</span>
Answer:
50 gallons of red
30 gallons of blue
Step-by-step explanation:
5 parts of the whole must be red, 3 parts of the whole must be blue, and there are 5+3=8 parts in total.
therefore, 1 part = 80/8 = 10 gallons
red : 5 parts
5×10 = 50 gallons
blue : 3 parts
3×10 = 30 gallons
Answer:
(g◦f)(-6) = -9
Step-by-step explanation:
(g◦f)(-6) means g(f(-6))
Put the number where the variable is and evaluate.
f(-6) = 3/2(-6) +5 = -9 +5 = -4
g(f(-6)) = g(-4) = 7 -(-4)² = 7 -16 = -9
Then ...
(g◦f)(-6) = -9
