Answer:
∠x = 72°
Step-by-step explanation:
since two sides are equal, their opposite angles are equal.
Then the upper angle is also equal to 54°.
All triangle angles add up to 180°.
∠x = 180 - 54 - 54 = 72°
Answer:
The cost for 20 students would be $120
Step-by-step explanation:
We know that 4x5=20 therefore we will multiply 30x4 which will give us 120.
Our final answer would be $120

First, you subtract 28 from 100 then divide that by 12 which would give you 6. so, X>6
5400 is the nearest hundred to 5403.264
Answer:x=8 and y=2
Step-by-step explanation:
To find 2x-4y=8 and 3x+6y=36
Solve simultaneously
Using elimination method
6x-12y=24
6x+12y=72
To eliminate x
-24y=-48
Divide through by -24
y=2
To get x
Substitute for y in equation 1
2x-4(2)=8
2x=8+8
2x=16
Divide through by x
x=8
