He uses 3/16 gal for 1/3 square foot.
1/3 square foot is 1/3 of 1 square foot.
1 square foot is 3 times as much area as 1/3 square foot, so he must use 3 times as much water. We need to multiply 3 * 3/16.
3 * 3/16 = 3/1 * 3/16 = 9/16
Answer: He uses 9/16 gallon.
Answer:
A
Step-by-step explanation:
Start with variable x.
4x - 6y = 28
Substitute the variables for numbers.
4(1) - 6(-4) = 28
Solve the new equation
4 + -24 = 28
Move to the second equation with variable y.
8x - 4y = 24
Substitute variables
8(1) - 4(-4) = 24
Solve
8 - (-16) = 24
The answer is A, x = 1, y = -4
Answer:
∠7 = 81°
Step-by-step explanation:
∠1 = ∠7
3x + 18 = 2x + 39
3x - 2x = 39 - 18
x = 21
∠7 = 2x + 39
∠7 = 2(21) + 39
∠7 = 42 + 39
∠7 = 81°
Answer:
6 tricycles
Step-by-step explanation:
Since 1 bicycle have 2 wheels..
11 x 2 = 22 wheels
40 - 22 = 18 wheels (Total number of wheels the tricycles have)
A tricycle have 3 wheels..
18 ÷ 3 = 6 tricycles
