The answer I think is 2. 150/7 is 21 R 3. 296/7 is 42 R 2.
Answer:
Let the weight of the leader dog = X
Then Darlene's dog weighs = 5X ( fives times as much)
Now add both together to equal 84 pounds:
5X + X = 84
Simplify:
6x = 84
Divide both sides by 6:
x = 84 / 6
x = 14
The leader dog weighs 14 pounds.
Darlene's dog weighs 70 pounds.
Answer:
-29
Step-by-step explanation:
y = 2 (-2) ^3 + 5 (-2) - 3
y = -16 -10 -3
y = -26 - 3
y = -29
Answer:
3.5
Step-by-step explanation:
(-8)(-1) -2[2-5(-1)]
8 -2 [ 2-5(-1)]
8 -4+10+2
-32+80+16
+32 +32
80=48

When put in matrix form, the coefficients of
... 3x -2y = 7
... x + 4y = 2
look like
The determinant is 3×4 - 1×(-2) = 14.
