Answer: 2x+4=10
Step-by-step explanation:
because each notebook would cost $3 so 2 x 3 = 6 +4=10
36/40 would be close to 1
Answer:
(0, 3 )
Step-by-step explanation:
Given the 2 equations
x + 3y = 9 → (1)
- 2x + 2y = 6 → (2)
Multiplying (1) by 2 and adding to (2) will eliminate the x- term
2x + 6y = 18 → (3)
Add (2) and (3) term by term to eliminate x, that is
0 + 8y = 24
8y = 24 ( divide both sides by 8 )
y = 3
Substitute y = 3 into either of the 2 equations and solve for x
Substituting into (1)
x + 3(3) = 9
x + 9 = 9 ( subtract 9 from both sides )
x = 0
solution is (0, 3 )
Answer:
<em>D.) It has a common difference of 3.8</em>
Step-by-step explanation:
When you subtract 
you get a common difference, the same goes for the other values: when you subtract the previous term from the next, you get a common difference of positive 3.8
Given that,
Length of 4 pieces of wood are 16.75 inches, 9 inches, 24.25 inches, and 12.5 inches.
To find,
The length of the strip of wood.
Solution,
Mark glues together four pieces of wood to make one long strip.
Long strip = The sum of 16.75 inches, 9 inches, 24.25 inches, and 12.5 inches.
L = 16.75 + 9 + 24.25 + 12.5
= 62.5 inches
Hence, the strip of wood is 62.5 inches long.
