Answer: y=0 and x=3
Step 1: Solve for x in 2x+9y=6.
(Subtract 9y from both sides)
( Divide both sides by 2)
Step 2: Replace x with 3-4.5y
Step 3: Solve for y
(By looking at this, we can determine that y=0)
Step 4: Replace y with 0
(Divide both sides 2)
Therefore, y=0 and x=3
Answer:
90 cups
Step-by-step explanation:
First, let's calculate how much cups of sugar we need for 1 batch of chocolate chip.
45 / 4 = 11.25
So, now we know that we need 11.25 cups of sugar to make 1 batch of chocolate chip.
Therefore, we know we need 90 cups of sugar for 8 batches because
11.25 * 8 = 90
Hope this helps ^^
Answer:
v²-1.89
Step-by-step explanation:
Area of wall= v²
Area of pipe= 1.7²
= 2.89
Area needs to be tiles= v²-1.89
Answer:
1. 4.7
2. 5,082
Step-by-step explanation:
1. To find the volume of a cone you use this formula . The diameter is 3 so to find the radius, divide it by 2 (3/2=1.5) and we know the height. Input the numbers into the formula and solve which is equal to . To find HALF, divide that answer by 2. , round to the nearest tenth, making the answer 4.7!
2. To find the volume of a rectangular prism you use . Input the numbers, to find the amount of water for the bigger tank (5,760). Now follow the same process to find the amount of water for the smaller tank which is 678. Now subtract the smaller tank amount (678) from the larger tank since you're taking the water from the bigger tank to fill the smaller one which equals 5,082.
Answer:
x=-1
Step-by-step explanation:
General equation of line is y=mx+n where m is slope. So, if we use point (-4, 8) and slope in equation we have 8= 2/3.(-4)+n
Then we have n=8+8/3, that is n=32/3
Therefore equation of our line is y=2/3.x + 32/3
For the point (x,10) in equation 10=2/3.x + 32/3
Then we have 2/3.x = - 2/3 then x= -1
