Answer:
no solution?
Step-by-step explanation:
2(5)-5=5(5)+7+3(5) <-- plug in 5
10−5=25+7+15
5=32+15
5=47
301 is the correct answer:)
Answer:
It holds approximately 4 litres in accent
Step-by-step explanation:
In terms, 1 litre = 1000 cubic centimetres.
-----------------------------------------
Therefore, to find How many liters of oil the container hold. Divide 4000 cubic centimeters by 1000.
⟼ 4000 ÷ 1000
⟼ 4
Therefore, 4000 cubic centimeters volume of oil holds 4L of oil
<h3>Answer:
122 degrees</h3>
==========================================================
Explanation:
Angle BAC can be shortened to "angle A" since the letter A is in the middle.
Angle BCA can be shortened to "angle C" for similar reasoning.
We're told that angles A and C are base angles. For any isosceles triangle, the base angles are congruent
-----------
Let's use this fact to solve for x.
angle A = angle C
7x+1 = 5x+9
7x-5x = 9-1
2x = 8
x = 8/2
x = 4
Once we know what x is, we can find each base angle
- angle A = 7x+1 = 7*4+1 = 28+1 = 29
- angle C = 5x+9 = 5*4+9 = 20+9 = 29
Both angles A and C are 29 degrees each, so this confirms we have the correct x value.
-----------
The last step is to use the fact that all three angles of a triangle add to 180 degrees. This will help us find angle B, which is the vertex angle.
A+B+C = 180
29+B+29 = 180
B+58 = 180
B = 180-58
B = 122
The vertex angle is 122 degrees.
So we can say either angle B = 122, or we could say angle ABC = 122
"angle ABC" is the same as "angle CBA".
Answer:
let cost of each pound of trail mix be x any y respectively
For 2 pounds of trail mix and 5 pounds of jelly beans, the total cost is $10
2x +5y = 10.....(1)
For 8 pounds of trail mix and 3 pounds of jelly beans, the total cost is $23
8x +3y = 23.....(2)
2x +5y= 10 ....... × 4
8x +20y = 40.....(3)
8x +3y = 23 ( from (2))
(3) - (2)
17y = 17
y= 1
8x +3y = 23
8x +3 = 23
8x= 20
x= 2.5
Cost for each pound of trail mix= $2.5
Cost for each pound of jelly beans= $1
