This one is worded oddly, but I think it's going to be:
(2x)/19
The equation would look like
Y=-4x+7
Y=mx+b
Answer:
x = 4
Step-by-step explanation:
We can use cross products to solve
84/12 = 28/x
84 * x = 12 *28
Divide each side by 84
84x/84 = 12*28/84
x =4
Answer:
water is Arthur's favorite drink
Step-by-step explanation:
The three drinks are lemonade, milk, and water.
If Paige's drink is a dairy product, milk would be the only answer there.
If Frank's drink comes from a fruit, lemonade would be the answer. Lemonade is made from lemons and sugar.
Water is the only choice left and Arthur is the only person who doesn't have a drink.
So, Arthur's favorite drink would be water.
You can set up an equation based off of the information given:
x represents the unknown number
3/5x - 1 = 23
add 1 to both sides to isolate the 3/5x
3/5x = 24
divide both sides by 3/5 to solve for x
x = 120/3
120/3 can be simplified into 40
Final answer: x = 40
