How many 1/2cups are there in 3 cups of flour
3x+y-2z=22
x+5y+z=4
x=-3z
3(-3z)+y-2z=22
-9z+y-2z=22
-11z+y=22
-3z+5y+z=4
-2z+5y=4
-11z+y=22
-2z+5y=4
-55z+5y=110
--2z+5y=4
----------------------
-53z=106
z=2
-2(2)+5y=4
-4+5y=4
5y=8
y=1.6
x=-3(2)
x=-6
x=-6
y=1.6
z=2
Answer:
Step-by-step explanation:
When finding the volume, we multiplied the 3 dimensions with degree of 1, 1 and 3 and got the binominal of degree 5. We summed up the degrees: 1 + 1 + 3 = 5.
- The <u>SUM</u> of the degrees of each factor is the degree of the product.
The equation would be y=1/3x. The slope rises 1 unit for every 3 units it moves right.
Option D is the correct answer.
Answer:
D. ∠B and ∠C are congruent.
Step-by-step explanation:
Since, ∠A and ∠B are supplementary.
Therefore,
∠A + ∠B = 180°.....(1)
Since, ∠A and ∠C are supplementary.
Therefore,
∠A + ∠C = 180°.....(2)
From equations (1) & (2)
∠A + ∠B = ∠A + ∠C
=> ∠B = ∠C
Hence, ∠B and ∠C are congruent.
