Answer:
7y+r+8x+94
Explanation
Given the algebraic expression 7(y+2) + (8+r) + 8(x + 9)
Given A, B and C. According to distributive law;
A(B+C) = AB + AC
A is distributed over C. In the same vein
On expanding the expression;
7(y+2) + (8+r) + 8(x + 9)
7y+7(2) + 8 + r + 8(x)+ 8(9)
7y+14+8+r+8x+72
Bringing the variables and constants together
7y+r+8x+14+8+72
7y+r+8x+94
Answer:
18 ounces of barley
Step-by-step explanation:
If Meg uses barley and wheat flour in a ratio of 2:3, we can set up equivalent ratios in order to find how many ounces of barley Meg would need if she uses 27 ounces of wheat flour:
= =
We can solve for 'x' (the number of ounces of barley) using a few different methods. We can cross-multiply and divide: 27(2) = 3x, or x = 18. We can also see what factor we multiply the 3 by to get 27 and multiply the numerator (2) by the same number. Since 3 x 9 = 27, then 2 x 9 = 18.
Answer:
x=9.768
y=6.972
Step-by-step explanation:
For this problem we have to use the trig relationships of cos and sin to figure out the lengths. Cos is equal to adjacent/hypotenuse so we can set it as x/r=.814 and since r is equal to 12 we can do 12 times .814 to get x.
We do a similar process for sin but sin is equal to opposite/hypotenuse so we can set up the equation y/r=.581 and we simply multiply both sides by 12 to get 12*.581 to get y.
Also for future reference adjacent and hypotenuse are based on the angle at use, since ∅ is on the bottom left x is the adjacent side and y is the opposite side.
