Answer:
The resultant expression would be 22 - 12x
Step-by-step explanation:
Let x be the unknown number,
Six plus four times a number = 6 + 4x
Four times four minus four times the number number = 4(4 - 4x)
Thus, Six plus four times the number plus four times four minus four times the number number = 6 + 4x + 4(4 - 4x)
Using distributive property,
6 + 4x + 16 - 16x
Combining like terms,
22 - 12x
If we say:
x = the smaller numbers we want to find
y = the larger number we want to find
Then, we can formulate two equations using the information given:
x + y = 68 [1]
y - 4x = 3 [2]
Now, we can solve simultaneously:
Rearrange [1] & [2] in terms of y:
y = 68 - x [1]
y = 4x + 3 [2]
Now equate them and solve for x:
68 - x = 4x + 3
5x + 3 = 68
5x = 65
x = 13
Sub x-value into either [1] or [2]:
y = 68 - (13)
y = 55
Answer:
YOUR ANSWER IS 9
Step-by-step explanation:
1.80/4= 0.45
2.70/6=0.45
5.40/12=0.45
0.45*20= 9$
Try measuring a different way, maybe with just cups
