So x + y = 45, and 4x + 5y = 195. Get y by itself. Subtract x from both sides in the first equation to get y = 45 -x, and subtract 4x from the second equation to get 5y = 195 - 4x. Divide by 5 to both sides to get y = 39 - 4/5x. 39 - 4/5x = 45 - x. Add x to both sides to get 39 - 1/5x = 45. Subtract 39 from both sides to get -1/5x = 6. Divide by -1/5 to get x = -30, or 30. In the first equation, do 30 + y = 45. Subtract 30 from both sides to get y = 15. Check. 4(30) + 15(5) = 195, or 120 + 75 = 195.
Replace x and y with the given values:
2(1/8 + 4) - (3/16*8)
Use distributive property:
1/4 + 8 - (3/16 * 8)
Simplify to get final answer:
8 1/4 - 1 1/2 = 6 3/4
Absolute value of -2 is 2
absolute value of -3 is 3
so now the equation is 4 x 2 - 3
do 4 x 2 first = 8
now do 8 - 3 = 5

Answer:
92 tablespoons
Step-by-step explanation:
16 tablespoons = 1 cup, in the recipe you need 1/4 cup for a batch, Rhonda needs 23 batches, so 23/4 to get the 1/4 cup, that's 5.75 cups, then you do 5.75*16 to get the tablespoons
