Answer:6/8
Step-by-step explanation:
Answer:
yes it is.
x = 4 and y = -3
Step-by-step explanation:
Solve simultaneously using elimination method:
equation 1 - equation 2
3x + y = 9 equation 1
-2x + y = 5 equation 2
_________
x = 4
plug 4 into any of the 2 equations and solve for y.
3(4) + y = 9
12 + y = 9
12-12 + y = 9-12
y = -3
Answer:
No
Step-by-step explanation:
To answer this you have to divide 3 and 3/8 by 1/3. The easiest way to do this without a calculator is to do this separately. First divide 3 by 1/3. When dividing fractions, the second number is flipped upside down and the two numbers are multiplied. From 3 pounds, Jasmine will be able to make nine 1/3 pound burgers.
3 ÷ 1/3 = 3 × 3/1 = 9
Next, divide 3/8 by 1/3. From 3/8 pounds, Jasmine will be able to make 1 1/8 burgers
3/8 ÷ 1/3 = 3/8 × 3/1 = 9/8 = 1 1/8
Add the two numbers together.
9 + 1 1/8 = 10 1/8
This is less than 12.
