Answer:
The temperature had a 6 degrees increase.
Answer: Assuming the unit is dollars, the answer would be $5,010.
Explanation:
Step 1: 8000-300 is 7700.
Step 2: 7700-290 is 7410
Step 3: 7410-400 is 7010
Step 4: 7010-2000 is 5010
So, the answer is Anna has $5,010 dollars left after giving Jim $300, buying shoes for $290, a suit for $400 and spending $2,000 dollars on a new phone.
Answer:81/4
Step-by-step explanation:
Answer:
8) x = 27
Angle P = x - 12 (15)
Angle Q = 5x - 27 (108)
Angle R = 2x + 3 (57)
Equation: (x - 12) + (5x - 27) + (2x + 3) = 180
x = 27
9) x = 14
Angle A = 7x - 6 (92)
Angle B = 3x - 5 (37)
Angle C = 4x - 5 (51)
Equation: (7x - 6) + (3x - 5) + (4x - 5) = 180
x = 14
10) x = 20
Angle K = x (20)
Angle L = x + 13 (33)
Angle J = 6x + 7 (127)
Equation: x + (x + 13) + (6x + 7) = 180
x = 20
11) x = 41
Angle Y = x (41)
Angle W = 2x - 5 (77)
Angle X = x + 21 (62)
Equation: x + (2x - 5) + (x + 21) = 180
x = 41
Answer:
-35,35,0
Step-by-step explanation:
Let's organise our information :
Now let's add them together :
- x+xy²+x-xy²=250y-240y
- 2x=10y
- x=5y ⇒ y= x/5
Let's replace y by x/5 in the first equation :
- x+x*(x/5)²=250*(x/5)
- x+ (x∧3)/25 = 50x
- 49x-(x∧3)/25=0
- x(49-(x²/25))=0
- x=0 or 49-(x²/25)=0
- x=0 or 49= x²/25
- x=0 or x²=1225
- x=0 or x=
or x= -
- x=0 or x=35 or x= -35
so x=[0,35,(-35)]
