11/5x-1 this should be the answer
Answer:
3.6 and 1.2
Or
-3.6 and -1.2
Step-by-step explanation:
Let x and y be the two numbers
xy = 4.32
x/y = 3
x = 3y
3y² = 4.32
y² = 1.44
y = +/- 1.2
x = +/- 3.6

(left to right)
4²-(3.1+6.4)+4.5
According to PEMDAS, we will do what is inside the parenthesis.
3.1+6.4 = 9.5
<em>4²-9.5+4.5</em>
Then we do figure out the exponent.
4² = (4)(4) = 16
<em>16-9.5+4.5</em>
Then we do subtraction then addition because PEMDAS also tells us we should do adding and subtracting from left to right. In this expression, subtracting is on the left side so we should do that first.
16-9.5 = 6.5
<em>6.5 + 4.5 = 11</em>
11 is your answer :)
Answer:
The cross multiplication would be 10(350) = 22(x).
Step-by-step explanation:
We would first convert meters to centimeters. There are 100 cm in a meter; this means 3.5 m = 3.5(100) = 350 cm.
The ratio of the height to base of the model is 10/22. The ratio of the playhouse would then be x/350. This gives us
10/22 = x/350
Cross multiplying, we would have 10(350) = 22(x).
