Jace bought 4 cookies and 2 brownies from the bakery.
Let x represent the number of cookies and y represent the number of brownies.
Since he bought $9 worth of cookies and brownies. Each cookie costs $0.75 and each brownie costs $3. hence:
0.75x + 3y = 9 (1)
Also, he bought twice as many cookies as brownies, hence:
x = 2y
x - 2y = 0 (2)
Solving equation 1 and 2 simultaneously gives x = 4, y = 2
Hence Jace bought 4 cookies and 2 brownies from the bakery.
Answer:
75 degrees
Step-by-step explanation:
30 + 75 = 105
180 - 105 = 75
Answer:
Bob could predict a <u>100%</u>, as if he has studied for a long time, and has learnt the content, he should be able to get 100%!
- Slope-Intercept Form: y = mx + b, with m = slope and (0,b) as the y-intercept.
So firstly, add both sides by 9x: 
Next, divide both sides by 10 and <u>your slope-intercept form is 
</u>
Now looking at our slope-intercept form equation, <u>the slope is 9/10 and the y-intercept is (0, -9/10).</u>
