A hamburger costs $2.5 and a milkshake costs $1.75
Step-by-step explanation:
- Step 1: Form equations from the given details. Let cost of 1 hamburger be H and cost of 1 milkshake be M.
4H + 2M = 13.50 ------ (1)
& 3H + 1M = 9.25 ------ (2)
- Step 2: Multiply eq(2) with 2 to make coefficients of M equal.
6H + 2M = 18.50 ------- (3)
- Step 3: Subtract eq(3) from eq(1)
⇒ - 2H = - 5
⇒ H = $2.5
- Step 4: Substitute value of H in eq(2) to find M.
⇒ 3 × 2.5 + M = 9.25
⇒ 7.5 + M = 9.25
⇒ M = $1.75
So the equation would be 10/N+3-6.
10/2=5 5+3=8 8-6=2. so if you plug in 2, it would make an answer of 2.
The triangle inequality applies.
a) 10000 < 1000 +10x
.. 1000 < 100 +x
.. 900 < x
b) 1000 < 10000 +10x
.. 100 < 1000 +x
.. -900 < x
c) 10x < 10000 +1000
.. x < 1100
x can be between 900 and 1100
Answer:
A. t=13 B. K= 23 C. t= 1 3/8
Step-by-step explanation:
A. 2t-30m=20
30 x 1/5= 6
2t-6+6=20+6
2t/2=26/2
t=13
B. 14+m=2k
14+12=2k
14+12=46
46/2=23
k=23
C. 1/8r+t=1
1/8 x (-3)= -3/8
1 - (-3/8)= 1 3/8
t= 1 3/8
Hope it helps!
You divide 690 by 100 which is 6.9
Therefore, one 50cent coin is 6.9g
