Answer:
-3°F
Step-by-step explanation:
-15 + 12 = -3
Answer:
-3
Step-by-step explanation:
Julia is deciding how many batches of sugar cookies and how many loaves of banana bread to make. Construct a system of linear inequalities that shows how many batches of sugar cookies (x) and loaves of banana bread (y) she can make with the flour she has but also reflects the fact that she can’t produce negative goods. There are 36 cups of flour available; to make one batch of sugar cookies, Julia needs 2 3/4 cups of flour, and to make one loaf of bread she needs 2 1/2 cups of flour.
Answer:
Step-by-step explanation:
we know that
Trina uses cup of sugar and
cup of flour in a recipe
so
by proportion
Find how many cups of sugar would she need if she uses cups of flour
Answer:
The given system of linear equations has infinite many solutions.
Step-by-step explanation:
Given equations are
σ-2ζ=3 eqn 1
4σ-8ζ=12 eqn 2
We will use elimination method to solve the linear system
Multiplying equation 1 by 4
4(σ-2ζ) = 4(3)
4σ-8ζ=12
We can see that the both equations in the system are same i.e. we get the same equations by simplifying the equations. The graph of both equations will overlap completely.
This means that the system has infinite many solutions.
Hence,
The given system of linear equations has infinite many solutions.
B. decrease the room temperature by 12°C
C. decrease the room temperature by 33°F
D. increase the room temperature by 18 K 2. Jim, Jane, Ann, and Bill measure an object’s length, density, mass, and volume, respectively. Which student’s measurement might be in liters?
A. Bill’s
B. Jim’s
C. Jane’s
D. Ann’s
1) Since 1°F= 9/5 (K - 273) + 32) after the calculus we find 1°F = 255.9 K
The answer is A. increase the room temperature by 22°F, because 55° F + 22° F = 77° and 77° F = 298.1K,
2) The answer is A: Bill’s. Bill has measured the object’s volume, and the unit of volume is the liter
Answer:
x-5+10 = 2x-7
the 2 lengths are equal
x+5 = 2x-7
x-2x=-7-5
-x=-12
x= 12
